A study showed that testing had detected Covid-19 infection in the United States in December 2019, providing further evidence that the coronavirus had spread globally several weeks before the first case was reported in China.
The study published Monday identified 106 infections in 7,389 blood samples collected from donors in nine states in the United States from December 13 to January 17. These samples were collected by the American Red Cross and sent to the US Centers for Disease Control and Prevention for testing to detect the presence of antibodies against the virus.
The report stated: "The findings of the report indicate that SARS-CoV-2 infection may have appeared in the United States in December 2019, earlier than previously known." The
report of mysterious pneumonia spreading in Wuhan, China first appeared in 2019 December. In the following weeks, the disease rapidly multiplied throughout the city and spread globally. The first US case appeared on January 19.
The revelation of the CDC researchers in the paper further strengthened people’s understanding that the coronavirus has quietly spread around the world earlier than known, and may reignite debate about the origin of the pandemic.
This is not the first evidence that the virus may have existed outside of China or infected China before 2020. A patient in France was found to be infected with the virus after being hospitalized with flu-like symptoms at the end of December. This is in line with official data showing that at the end of Covid- January, 19 people returned home from Wuhan.
CDC research shows that isolated infections occurred in the western United States in mid-December. Antibodies were also found in other states in early January, and only then did they know that the virus had been introduced into these places.
Scientists pointed out that this antibody is unlikely to develop to inhibit other coronaviruses, because 84 samples were found to have neutralizing activity against SARS-CoV-2.
They also pointed out that it is impossible to determine the degree of infection in a state or country based on whether the sample or case is spread locally or related to travel.

The COVID-19 virus was once called the "best equalizer" because of its potential to infect everyone at the speed of a pandemic. But the data on mortality has different opinions.
The coronavirus does not affect everyone equally. Instead, it exacerbates racial disparities in the overall health outcomes of the United States. The gap is caused by the country’s own existing conditions: people’s living and working conditions are almost equal in terms of pollution levels and prevention of harmful toxins.
These differences are most obvious in urban environments that have become hot spots for pandemics. There, the proportion of ethnic minorities killed by the coronavirus is higher than the total urban population.
At the epicenter of the country’s pandemic, New York City, the death toll of blacks and Latinos was about twice the total population. In Chicago, the gap is even worse: Black people account for 70% of coronavirus deaths, but about 30% of the city’s population.
In early April, before the in-person vote in Wisconsin, about 80% of Milwaukee’s coronavirus deaths were black, even though the city’s share of blacks in the population was only 25%. Since then, seven more coronavirus cases have been linked to voting on election day, but the full impact of the spread of the virus is unclear.
These statistics shocked a lot, but environmental justice experts and advocates are not surprised.
In an interview with Outlook, PolicyLink President and CEO Michael McAfee said: "During a pandemic, there is no balance from total inequality." "I think we missed it." The storyline is that we are here in design, we are here in our arrogance, we are here in our lack of leadership, we are here, because our organization no longer cares and knows how to serve those who need it most People in need. Our investment withdrawal has haunted us again, but it has been hidden from people’s sight."
In the United States, about 70% of blacks live in counties with pollution levels that exceed federal standards.
Although there are regulations and restrictions on harmful toxins used in industries ranging from energy to agriculture, these regulations are not always followed, and their impact disproportionately affects minority groups. According to EPA data, approximately 70% of black Americans live in counties where pollution levels exceed federal standards and therefore violate federal laws.
Blacks and Hispanics are also more likely to engage in basic jobs, which means they will continue to work and face the risk of coronavirus exposure, with limited protective measures and protective equipment. In many cities, ethnic minorities account for the majority of important employees in the public sector. They operate and maintain buses and subways, and work in public hospitals and clinics.
For a long time, the factors that determine people's health are various environmental factors at home and work, as well as differences in access to conventional medical services. Before the outbreak of the coronavirus, it is well known that black people are more likely to suffer from asthma or cancer due to frequent exposure to harmful toxins. Black children are more likely to die from asthma attacks than white children. Blacks are also more susceptible to lung disease than whites, although they are less likely to smoke.
Jacqui Patterson, senior director of NAACP’s Environment and Climate Justice Program, said: “I say that the coronavirus has found fertile ground for the vulnerability of this type of health condition.” “When you encounter these pre-existing conditions, people have already The airway is more likely to die at [beginning], and the things you add will put more pressure on the airway, such as COVID-19, which exacerbates the stressors they get into trouble.”

Patterson added, when someone lives In heavily polluted areas, their lungs are more difficult to work, so when a disease that attacks the respiratory system arrives, it will exacerbate the negative health effects that existed.

For its part, the current federal government does not prioritize environmental protection, let alone consider the protection of race. Since taking office, the Trump administration has been working to reduce the previous Clean Air Act standards and regulations in industry operations.

Not only the federal government should be blamed. When considering pollution and industry, local governments often fail to prioritize public health. The Little Village community (mainly Latino community) in Chicago is adjacent to an energy industry plant. Despite the coronavirus pandemic, the city allowed Hilco to dismantle an old coal plant that covered the area with smoke and dust. The small village is already one of the most polluted places in Chicago. Antonio Lopez, a senior consultant at the Chicago Freshwater Laboratory, said: "These differences in injury, environment, and death have already existed in Chicago. I think the coronavirus has exposed these differences again." "But I think it also Emphasize to us that the solutions we need to consider must be different." Lopez added that these environmental justice solutions will not require a "thorough approach" and must be developed around the different vulnerabilities of specific communities.

Among these loopholes, race is an important factor. McAfee, along with the We Must Count Alliance and other advocates, is committed to ensuring that race data is collected during the pandemic. This can be a tricky process. As McAfee puts it, many public institutions "people who don't want to provide data very much", "people who say'we need data to make informed decisions', so this has become a hot topic-22."

McAfee said , But data is essential. "You are injecting trillions of dollars into the economy. We hope to raise accountability issues for who needs these dollars and where to go."

It turns out that the first round of small business loans and assistance in the CARES Act did not involve Minority enterprises. McAfee said that in order to avoid the mistakes brought about by past crises, not only about public health, but also about economic recovery, it is now necessary to collect the demographic data most affected by the coronavirus.

However, for its part, the federal government has not yet collected race, ethnic and geographic data on the impact of the coronavirus. Since the beginning of the pandemic, there have not been many hospitals or states. In the absence of such data, one might misunderstand which group is most vulnerable. Peggy said: “When the media says that people of a certain age group will be at higher risk, that’s not right, because in communities of color, people of lower age have chronic diseases and live with severe air pollution. "Shepard of the WE ACT environmental justice organization in Harlem. "This means that the risk is higher for communities of color when you are young."

Although many people call for a return to normal life, these environmental justice experts and advocates emphasize that "normal life" will not improve the hundreds of Americans who were struggling before the coronavirus. The lives of millions. They called for change.

There is no sign of the pandemic that things will get better, and the economic impact seems to be much worse. McAfee explained that simply restoring the status quo will leave many people behind. "For the 100 million people living in 200% poverty before COVID-19, this will never be good enough. As experts say, if this will be worse than 2008, if the unemployment rate will be even higher than during the Great Depression. High, then it's safe to say that black people and brown-haired people are F*uking," he said.

"It is absolutely impossible to miss it," Patterson said. "Whether it is Hurricane Katrina, the BP oil spill disaster, or all these different disasters that have occurred in the past, the pattern has always been the same. Therefore, in order to prevent us from falling into this juncture, we must stop thinking: "How do we To improve the lives of the poor, how to improve the lives of people who are discriminated against because of race, and how do we make people of one kind, that kind and another kind of life better. "We must review systemic inequality and its root causes."

The 2022 Beijing Winter Olympics and the Paralympic World Media Conference opened as scheduled on the 19th through a remote video conference, from the International Olympic Committee, the International Paralympic Committee, the National (regional) Olympic and Paralympic Committees, More than 400 people from the International Individual Sports Federation and global media representatives overcame difficulties such as jet lag and participated in the meeting.
　　Zhang Jiandong, Vice Mayor of Beijing and Executive Vice Chairman of the Beijing Winter Olympics Organizing Committee, Lucia Montanarella, Chairman of the International Olympic Committee Press Committee and Director of Media Operations, attended the meeting and delivered speeches.
　　The World Media Conference is one of the most important milestones before the Beijing Winter Olympics Organizing Committee's media operations. It is the only opportunity to directly introduce the progress of various preparations to the news media around the world during the preparations for the Beijing Winter Olympics. In order to consider everyone's health and improve the efficiency of the meeting, after consultation with the International Olympic Committee and the International Paralympic Committee, the conference was held in an innovative way through remote video.
　　Zhang Jiandong addressed the conference: “The media is an important customer group for the Beijing Winter Olympics and the Paralympic Winter Games. Providing good services to the media is an important task in preparing for the Winter Olympics. We attach great importance to the operation of the media and strictly fulfill the bid promises. He has done a lot of basic work and is committed to meeting the needs of media friends in reporting and reporting in China during the preparation period and during the competition."
　　He said: "The new crown pneumonia epidemic has had a great impact on the production and life of countries around the world and international large-scale events, but this is all We cannot stop our firm pace in preparing for the Winter Olympics. We are full of confidence in this. The epidemic also has an impact on the coverage of events. We will work with major media around the world to study media interviews and epidemic prevention for the Beijing Winter Olympics and Paralympics. We will strive to provide you with comprehensive, efficient and convenient media service guarantees. At the same time, I hope that you will continue to care and support the preparations for the Beijing Winter Olympics and the Winter Paralympics, and help us do better work and work together. The world is dedicated to a successful Olympic event."
　　Lucia Montanarella said: "Seeing the Beijing Winter Olympics Organizing Committee's high-level attendance at the opening ceremony of the World Media Conference is enough to prove that the Beijing Winter Olympics provides high-level services and services to the media. Commitment to facilities. Understanding that the Beijing Winter Olympics Organizing Committee attaches so much importance to the media and its operations is of vital importance to the global media."
　　Xu Jicheng, director of the media operation department of the Beijing Winter Olympics Organizing Committee, said that the purpose of this meeting is to let reporters covering the Beijing Winter Olympics understand the working and living conditions during the games, so as to facilitate the formulation of budgets, interviews and personnel plans for their respective organizations.
　　He introduced that the number of participants this time has created the highest number of previous World Media Conferences for the Winter Olympics, showing that the global media attaches great importance to the Beijing Winter Olympics. Considering that media representatives at the conference are temporarily unable to come to China for field visits due to the impact of the epidemic, the Media Operations Department has taken multiple measures to use various communication methods such as live video conferences, venue simulation systems, online Q&A, and email one-to-one responses to break the boundaries of time and space. Establishing trust among the media allows them to learn more about Beijing, and allows the Beijing Winter Olympics Organizing Committee to serve the media more specifically.
　　According to the meeting schedule, from the 19th to the 20th, participants listened to the Beijing Winter Olympics Organizing Committee’s presentations on 15 business areas including news operation, sports, venue facilities construction, registration, accommodation, technology, transportation, security, and news promotion. All business areas accept questions from participants. From the 21st to the 22nd, the photography operation introduction meeting and the unilateral meeting with various media focused on answering the questions of the media.

According to the US "Wall Street Journal", a government study released by US CDC scientists on November 30 showed that as early as mid-December 2019, the new crown virus appeared in the United States, which is earlier than the official discovery of the new crown virus in China. Several weeks, one month before the first confirmed case in the United States was discovered by the US public health department.
　　According to the US "Wall Street Journal", a study published in the journal "Clinical Infectious Diseases" by scientists of the US Centers for Disease Control and Prevention showed that 106 of the 7,389 blood donations collected by the American Red Cross from residents of 9 states in the United States One found evidence of infection with the new coronavirus. These blood samples were collected by the Red Cross between December 13, 2019 and January 17, 2020, and sent to the Centers for Disease Control and Prevention for testing to see if there are antibodies against the new coronavirus. During the analysis, the scientists found antibodies to the new coronavirus in 39 samples collected from California, Oregon and Washington from December 13 to December 16.
　　"The new coronavirus infection may have appeared in the United States in December 2019, which is earlier than our previous understanding." The article also pointed out that these findings indicate that there were isolated cases of new coronavirus infection on the west coast of the United States in mid-December. In addition, from December 30 to January 17, 2020, scientists found 67 blood samples with COVID-19 antibodies in Massachusetts, Michigan and other places.
　　The Wall Street Journal pointed out in the article that the results of this study also show that there is more and more evidence that the new coronavirus appeared outside of China earlier than previously known times. For example, when researchers retrospectively analyzed samples of French hospitalized patients on December 27, 2019, they also discovered this virus. Research reflects that the new coronavirus may not only appear in the United States earlier than previously known, but researchers have also found evidence that the spread of the virus in the United States is much more widespread than test results indicate.

The coronavirus is destroying Warren Bell's life in New Orleans. His 81-year-old cousin was hospitalized due to COVID-19. Due to the epidemic, his youngest daughter took a vacation for cooking in a large restaurant. His eldest daughter nurse worked for 12 hours at the "New Orleans East Hospital", "COVID-19 patients began to die a few weeks ago."

"A paramedic died a week ago, and her supervisor is in isolation. Naturally, I I worry about her every day," said Bell, a former TV news anchor and radio host. A football coach at the school where his wife works and a longtime friend, Jazz Patriarch Ellis Marsalis recently died of the disease. He said: "This is a terrible thing."

In the center of American cities, the new coronavirus is destroying African-American communities. The environment in which most people live, the work they do, the prevalence of health conditions such as high blood pressure and diabetes, and the treatment of medical institutions have caused a toxic storm of serious illness and death. (These common underlying conditions make the coronavirus worse.)
Among the cities, counties, and states that report racial data, the impact of the coronavirus on black communities is extremely large and disproportionate. According to data from the Centers for Disease Control, almost one-third of infections across the country affect black Americans, even though blacks make up only 13% of the American population. Similarly, according to the Associated Press analysis of available state and local data, nearly one-third of the people who died nationwide were black.
In some places, the death toll of African Americans is even higher. 36% of the recorded coronavirus deaths in Wisconsin are black, even though they only make up 6.7% of the state’s population. Of the deaths in Shelby County, Tennessee (including Memphis), 71% are African-Americans, accounting for half of the population.

In response to the inequality faced by African Americans and other races and minorities, the legally established Civil Rights Lawyers Committee worked with hundreds of medical professionals on April 6 to request the U.S. Department of Health and Human Services and the CDC Publish daily race and ethnicity data on COVID-19 testing and results. As the CDC still did not respond, the team sent a second letter because data from the other two weeks showed that the numbers were deteriorating.

The Commissioner of the City of Albany, Georgia, Demetrius Young said: "People are either shocked or numb." 90% of the dead were African Americans. "They are very afraid to wait to hear about the next death. People will feel a little tingling and will be frightened immediately. Someone called me and cried because a friend who had been to her house tested positive. She suffers from anxiety. . "
Why did it affect African Americans so much?

"Look in our community: you will see food deserts, transportation deserts, and educational deserts," said Dr. Celia J. Maxwell, an infectious disease physician and associate dean of the Howard University School of Medicine in Washington, DC. "You want [in order] to keep the community Good health has disappeared from our colored communities.”

Maxwell added: “For people of color, especially African Americans, they have to deal with too many issues-health, socioeconomic, poverty, education and Systemic racism.” “Considering all these factors, it is not surprising that these patients will be more susceptible to injuries such as COVID-19. The cause of the epidemic is the health care gap.

Health gap experts say that other contributing factors are Close ties between family, friends, and churches in black communities. In addition, urban areas and families are overcrowded.
COVID-19 has experienced gatherings attended by African Americans, including dances celebrating sheriff representatives and Detroit tight ballrooms; Funerals and birthday parties in Chicago; an annual African-American ski trip in Idaho, bringing together 600 skiers from all over the country and as far as London; and a carnival in New Orleans

despite being African American Many health problems that are common in the
U.S. make them more vulnerable, but some people (such as skiers) are relatively healthy, exercise and earn high salaries. Ebony Hilton, associate professor of anesthesiology and critical care medicine at the University of Virginia Dr. said that among the top 13 major causes of death in the United States, African Americans have a higher attack rate, eight of which are heart disease, stroke, cancer, influenza and pneumonia, diabetes, HIV, kidney failure, and homicide. .
She said: "I know that the coronavirus will cause a higher death rate in the African American community." "I know we will face an uphill battle. I can see the storm coming."

Tulane University School of Medicine, New Orleans Dr. Keith Ferdinand, a professor of medicine in the United States, said that many variables make African Americans more susceptible to COVID-19. They include working in the service industry or “basic jobs” that require them to expose themselves to other people who may be infected; using public transportation to go to work; lack of opportunities for early testing; and historical mistrust of the medical system due to previous biases . Ferdinand said that this has led to "the mixture of many difficulties faced by African Americans, which may increase or even aggravate the burden of coronavirus risk factors."
In addition, the former chairman of the Democratic Party of Maryland, Baltimore US House of Representatives candidate Maya Rocky Moore · Cummings (Maya Rockeymoore Cummings) said that many African Americans are focused on hourly work without health benefits. She said that they are either the first to lay off workers, they are now unemployed and uninsured, or they are considered "important workers" and are suffering from the virus. (See photos of basic workers in frontline services around the world.)

"When you collect trash, go to the store or look out the window," said Rockeymoore Cummings, who is also the widow of US Rep. Elijah Cummings. "We have overexposed people who have not protected their own interests."

From the cities, counties, and states that collected COVID-19 data, here are some findings.

Albany
, Georgia In this city of 75,000, 150 miles south of Atlanta, 90% of COVID-19 deaths are African Americans, compared with 72.5% of blacks in this town. Authorities said they believe that the two funerals and the annual Snickers Marathon, which may take place in the first week of March, with 1,000 athletes participating, contributed to the spread.

"We are still in a crisis phase," Young said. "We have already had 50 deaths. I have two friends that I will never forget. I have many acquaintances with the infected faith communities."
He said that the African-American community in Albany is very close, and the 30% poverty rate has increased. In this case. "Many people in the population have suffered from difficult access to medical care. And we have a large elderly population, which is not very healthy," he said.

One person serving on the jury of the famous murder trial seemed to inadvertently "spread the virus to many others in the court, including the chief judge who fought for his own life. Since then, another judge has died.

Albany Royal The church pastor, Rev. Jarod Pierce, said that he only left home when absolutely necessary. He said that one of the reasons it was hit so badly was that people didn’t take it seriously until it was hit. Close to home. "Someone called me last week. Their mothers, grandmothers and uncles all fight for their lives. "

Although the mayors across the state have responded and public health leaders have warned to proceed with caution, Georgia Governor Brian Kemp relaxed some social isolation measures on Friday and opened some non-essential businesses. Including hair salons, nail salons, barber shops and bowling alleys. The
mayor’s website states that in the country’s capital, 81% of the deaths are African Americans, compared to 46% of the city’s population. Many deaths occurred in the city. The poorest and predominantly African-American community.

Sandy Henderson, the retired conference manager, is one of 600 African-American skiers in the United States and as far as London. He left for Idaho in early March. State Ketchum participated in the annual national skier sorority. Henderson of the Washington DC subsidiary Black Ski Inc. and her companion fell ill. The

69-year-old Henderson said: “I feel so cold. All I can do is climb the stairs to cover up. "Their doctor prescribed two antibiotics for common bacterial infections and sent them home. Later this week, Henderson fainted on the bathroom floor.
A few days later, when they still felt bad, they knew something was wrong. In the nearest emergency room, they were tested for influenza, streptococcal laryngitis, and COVID-19. Three days later, they all found positive for COVID-19. After both were deemed to be in no danger, the hospital sent them home.

Henderson said that at the same time, as many as 100 people fell ill from ski trips and at least 4 people died. She and her companions are fortunate not to suffer from underlying health problems, which makes this disease so deadly to others.

Chicago
Although African Americans make up only 30% of the city’s population, 56% of its deaths are African Americans. Mayor Lori E. Lightfoot said these figures are “disturbing” and “a profound reminder of the deep-seated problems

that have caused different health effects in Chicago’s communities for a long time.” It is personal to Marshall Hatch, the pastor of the historic Johor Bahru Pilgrim Missionary Baptist Church. "My sister died of a corona-related disease 7 days ago. My best friend passed a few days before that."
He said that the church is providing virtual services, with "a singer, a minister, a Famous musicians" and producers broadcast live. "Naturally, our [streaming media] numbers have increased tenfold. Due to anxiety, fear and isolation, these services are people’s spiritual lifeline."

He said that Hatch’s church is one of the largest churches in Chicago’s West Side, and One of the poorest communities in the city. The church suffers from violence and unemployment, and its average life expectancy ranks second among the 77 neighborhoods of Chicago. "This epidemic magnifies the inequality that people experience every day."

Hatch said, this is "the story of two cities." "The life expectancy gap between our community and other communities is huge, which is unethical. Our disease is based on stress, food deserts, and violence in desperate communities."

Comprehensive reports from The Wall Street Journal and CNN: More and more research reports indicate that before the new crown pneumonia epidemic rages in Wuhan, China, the new crown virus may exist in many places around the world. The latest report issued by the US Centers for Disease Control and Prevention (CDC) on November 30 pointed out that as early as mid-December last year, people on the West Coast of the United States were infected with new coronary pneumonia, which is more than the first confirmed case reported by the United States (January 19, 2020) It was about a month earlier, even several weeks before the date China officially notified the World Health Organization (December 30, 2019). A report published by the medical journal "Journal of Clinical Infectious Diseases" on November 30 showed that scientists from the US CDC found that the Red Cross collected 7,389 blood donors from nine states from December 13 last year to January 17 this year. Among the blood samples, up to 106 samples have antibodies to the new coronavirus (SARS-CoV-2).

The case of the new crown disease was mistaken for the flu.

Researchers found that among blood samples containing antibodies to the new crown virus, 39 were from California, Oregon and Washington states from December 13 to December 16 last year. This shows that in mid-December last year, there were individual cases of new coronavirus infection on the west coast of the United States.

In addition, between December 30 last year and January 17 this year, researchers also found antibodies to the new coronavirus in 67 samples from Massachusetts, Michigan, Wisconsin and other places. This means that by the beginning of this year, the distribution of new coronavirus infection cases is wider, but they are still individual cases.

The report reads: “The United States may have been infected with the new coronavirus in December 2019. This is earlier than our previous knowledge.” Washington State reported the first domestic confirmed case in the United States on January 19 this year, but later Studies have found that suspected infected patients have appeared in California, New Jersey and other places before this time. As early as March 11, US CDC Director Redfield admitted in a congressional hearing that deaths from new coronary pneumonia in the United States were mistaken for influenza deaths.

Testing blood samples is the key to traceability,

and the report released by CDC not only proves that the start time, speed and scope of the spread of the new coronavirus around the world are earlier, faster, and wider than previously recognized by all walks of life, but also highlights the regular testing of blood samples. , The important value of seeking evidence of the spread of new coronary pneumonia.

In addition to the United States, France, the United Kingdom, Italy and many other countries showed signs of the spread of the new crown virus last year, well before they reported the first case. In France, doctors retested past samples and found that the country had a new crown case at the end of December last year. This is nearly one month earlier than the first confirmed cases officially announced by France. The WHO stated on November 23 that there may be more than one case of the new crown "patient zero".

Chinese Foreign Ministry spokesperson Hua Chunying said on November 30 that the source of the virus is a complicated scientific issue. There are now continuous reports on the time and location of the outbreak in the world, indicating that the virus is breaking out in multiple locations and places on a global scale. , Should insist that scientists carry out international scientific research and cooperation on a global scale. It is hoped that all countries can adopt a positive attitude of cooperating with WHO like China. Regarding the

epidemic as an attack on China's weapons

Some commentaries pointed out that the new crown virus pandemic is a sad disaster for the world. For Western politicians with ulterior motives, it has become a weapon used to attack China. U.S. President Trump deliberately concealed and ignored the severity of the epidemic from the beginning. In order to boost the election situation, he did his best to shirk responsibility for the ineffective fight against the epidemic, using terms such as "Chinese virus" and "Wuhan virus" to stigmatize China. .

As of December 1, the number of confirmed cases in the United States has exceeded 13.54 million, and more than 268,000 have died. Following President Trump's defeat in the general election, he appointed the White House Special Advisor on the Epidemic in early August. Atlas, which caused great controversy in support of "herd immunity", announced his resignation on November 30. Atlas believes in "herd immunity" and opposes anti-epidemic measures such as wearing masks and closing cities. It advocates opening schools and even claims that the new crown virus "has no effect on children." This view runs counter to the mainstream consensus in the scientific community.

On the other hand, American medical staff are often overworked when they are under-equipped. At the Joint Memorial Medical Center in Houston, Texas, doctor Walloon has been working for 250 consecutive days. During Thanksgiving, elderly patients with new coronary pneumonia who were forced to be separated from their families wept alone. Wallon hugged him into his arms to comfort him, this picture is sad.

WHO Calls Not to Politicize the Origin of the Virus

Comprehensive Agence France-Presse and Reuters reports: WHO Director-General Tedros Adhanom Ghebreyesus said at a press conference on November 30 that the WHO will use all means to investigate the source of the new crown virus to avoid a similar global epidemic in the future . He also called on countries not to politicize the epidemic.

Tan Desai said that the WHO's position is very clear and will do its best to find the root of the new crown virus. "We need to know where the source is. This will help us avoid similar infectious diseases in the future." He emphasized that the relevant investigation is a scientific issue and urged critics who think that the investigation should be led by China, not to spread the virus. The politicization of traceability issues creates obstacles to investigations and everyone should cooperate on related issues.

The WHO announced last week that a team of WHO experts will go to Wuhan, China, to investigate the animal traceability of the new coronavirus. China has always maintained communication and cooperation with the WHO, and based on its own traceability work, is the first to invite WHO experts to China for traceability cooperation.

On November 30, Tedros dismissed allegations that the WHO team was not transparent enough. He stressed that the list of experts has been published, team members from the United Kingdom, the United States, Japan and other countries, "we have nothing to hide, would like to know the origin of the new virus crown. I do not want any outside misunderstanding on this goal."

Four The timeline of the outbreak on the continent has been greatly extended. Spanish

researchers found the virus genome in a wastewater sample on March 12 last year.

Italian

researchers found that 111 people had COVID-19 antibodies in 959 blood samples collected from September last year to March this year, including 4 volunteers who provided blood samples in early October last year, indicating that they may have been infected with the new coronavirus in September last year. . A hospital

in

Colmar, France checked more than 2,400 chest CT images from November last year to April this year and found that the earliest suspected case could be traced back to November 16 last year.

United States

The California Department of Health found in April that as early as February 6, there were people who died of new coronary pneumonia in the area. The deceased were mistaken for the flu. The Mayor of Belleville, New Jersey, Melham said that he had been infected with the virus in November last year and had the new crown antibody. The first domestic case reported by the United States officially appeared on January 20. Analysis of sewer water samples in Santa Catarina State,

Brazil

from October last year to March this year showed that the new crown virus was present in sewage samples last November, three months earlier than the first case announced by the Brazilian government in February this year. Among 500 blood samples collected from January to March last year in the Kanto Koshinetsu area of

Japan

, two of the samples tested positive for antibodies to the new coronavirus.

Five Questions about the U.S. Epidemic

1. When did the new coronavirus appear in the U.S.?

The first domestic confirmed case announced by the U.S. appeared in Washington State in late January. However, an autopsy report in California indicated that the virus began to spread in the community in January or even earlier. A New Jersey mayor said that he had been infected in November last year. Who is the "Patient Zero" in the United States?

2. How many flu patients died of new coronary pneumonia?

Many American epidemiologists said that some were diagnosed Cases of influenza may be related to infection with the new coronavirus.

3. What is the truth about e-cigarette pneumonia?

In July last year, a mysterious e-cigarette pneumonia broke out in Wisconsin. The symptoms were almost the same as those of new coronary pneumonia. Why is the concentration of e-cigarettes with a history of more than 20 years causing pneumonia now?

4. Why is the Trump administration ignoring the epidemic warning?

Why does the United States, which has leading medical resources, technology and talents, have timely warnings from China and the WHO? Still ignoring the risk of the epidemic, and even deceiving the public with "everything is under control"?

5. Why is the White House's anti-intellectual and anti-scientific anti-intellectual and anti-science?

There is no scientific basis. Remarks: Ignoring epidemic prevention measures, some senior White House officials refused to wear masks when inspecting epidemic prevention work; the pandemic spread, but public health experts were left alone.

The Washington Post's analysis of early data from jurisdictions across the country found that compared with white Americans, the new coronavirus appears to be affecting and killing black people at an extremely high rate.
Analysis shows that the infection rate in most black counties is three times that of most white counties, and the death rate is six times that of most white counties.
"Why is the black community three to four times higher than others?" President Trump asked at the White House task force briefing on Tuesday. "It doesn't make any sense, and I don't like it. We will collect statistics in the next two to three days."
But based on what we know about inequality in many black communities, it does make sense. The amendment aims to better understand why the coronavirus apparently killed black Americans faster than other groups. Here are some of the main reasons.
1. The incidence of basic health conditions is higher and the chance of getting care is less.
Long-term data show that black Americans have a higher rate of high blood pressure, heart disease, diabetes and lung diseases. Medical experts say that the coronavirus has exacerbated the challenges posed by these diseases, and this is what Trump administration officials first cited when discussing the differences in Tuesday’s briefing.
Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases, said on Wednesday: “There has always been a health gap between the African American community, but now this crisis is again, which clearly illustrates this. Kind of unacceptable level.".
Uché Blackstock, a physician who works at the Brooklyn Emergency Center, said that existing health problems have a particularly serious impact on black communities, making complications more likely.
Blackstock said: "We bear a higher burden of chronic diseases, which makes us more susceptible to more serious complications from the coronavirus."
A 2014 study by the National Institutes of Health found that hospitals in predominantly black areas are more likely to fail than hospitals in predominantly white areas, which often makes it difficult for black Americans to obtain medical services where they live. Blackstock said: "We cannot get medical services. If we do, the quality of medical services may be the worst because they are usually called minority services." "And they may not have experts or sufficient resources to take care of COVID-19. -19 patients. Medical service providers have implicit biases. Research shows that white patients are more biased than colored patients."
2. Black Americans have a lot of "basic" jobs.
Blacks are more likely to engage in jobs that may make workers and health worse. People stay in close contact with each other and make it more difficult to engage in socially alienated work.
According to data from the Bureau of Labor Statistics, the U.S. Bureau of Statistics compiled by the Center for American Progress, the proportion of people in black is too high compared to the food industry, the hotel industry and the total population of taxi drivers and drivers.
Preston Mitchum, policy director of URGE, a non-profit organization that advocates for free policy issues, said that the employment opportunities that many blacks can take advantage of often put them at greater risk of being severely harmed by the coronavirus.
"The distance between the black community and other communities is not less than that of other communities. If there is any, it is probably because many of us are essential workers or engage in odd jobs to sustain our lives. These jobs require more Face-to-face interaction.”
Jason Hargrove, a 50-year-old bus driver in Detroit, released a videotape that spread the virus. He said he thought he was infected with the coronavirus because of a The passenger coughed repeatedly without covering his mouth. Less than two weeks after the video was released, Hargrove died.
His wife Desha Johnson-Hargrove wrote for Time magazine: "He knew he was not feeling well." "I took over him soon, and I still can't believe it. There. A day ago, he was in very good shape-a tall man with a height of 6'3. That day changed my life forever."
3. Lack of information
Keneshia Grant, a professor of political science at Howard University, focuses on the relationship between black voters and state and local governments. She said that bad information from government leaders has changed the experience of black people with the coronavirus.
In short, I don’t think the problem is that blacks don’t get information from their government. The problem is that we get bad and inconsistent information from the government. She said: "We also got information from people who don't seem to represent us."
Grant said that mixed information from the Trump administration and some governors in some states with large black populations caused confusion. The majority of black Americans-nearly 60%-live in the South. Florida, Alabama, Mississippi, and Georgia are all led by governors, and their information on how to stay safe is often inconsistent with federal government guidelines.
She said: "I think what the black America and the whole country need is clear information from the federal government." "I think this is especially true, because it took a long time for blacks to see their representatives in this crisis. "
she added:" strong, coherent federal information will help achieve this goal. "
US surgeon Jerome Adams (Jerome M. Adams) comes Friday in the case of the White House Task Force briefing , How black people are greatly hurt by this disease.
He said: "This is shocking, but it is not surprising that people of color bear a greater burden of chronic health conditions." "The long-term burden of medical diseases may make it particularly difficult for people of color to resist the ravages of covid-19. And in fact (possibly) the burden of social disease is also increasing.”
Adams talked about the need to better promote the importance of keeping distance from society for people of color, and talked about how individuals in these communities follow the guidelines. demand. 4. Housing gap
Vedette Gavin, the lead researcher of the Environmental Protection Law Foundation's Healthy Neighborhood Research, told the Amendment that racial differences in housing make black lives more susceptible to disease. Her organization seeks to better understand and address the impact of community changes on the health of the Boston metropolitan area.
A study conducted by Princeton University in 2017 found that black children are more likely to develop asthma because they live in old buildings with feces and rodent infestations and live in isolated communities beside busy highways These harmful organisms discharge harmful substances in the air into the air.
The information released by the Centers for Disease Control and Prevention pointed out that patients with asthma are at greater risk of dying from the coronavirus.
Adams said on Friday: “People of color are more likely to live in densely populated areas and multi-generational housing, which increases the risk of the spread of highly infectious diseases like covid-19.”
Gavin said: “There is a housing aspect. This is a huge problem." "Poor housing stock and illegal acts of asbestos, mold and Co*kroaches increase the risk and prevalence of respiratory and lung diseases, which increases the severity of symptoms in people with co-oviposition. When When rent is unaffordable, black and Latino families in urban centers tend to double and triple, making separation between families impossible."

Xinhua News Agency, Beijing, January 7. As the preparations for the Beijing Winter Olympics enter the final critical period, the construction of related projects for the Winter Olympics has attracted much attention. The reporter learned from the "Two Sessions" in Shijingshan District, Beijing on the 6th, that this year, Shijingshan District will complete the construction of the Winter Olympics venues and supporting facilities, and build the main winter Olympics operation center, Shougang ski jump supporting facilities and the Apple Orchard comprehensive transportation hub.

The U.S. concealed the 2019 Covid-19 outbreak that originated in the U.S., and now it's causing disaster! In the current major new coronavirus epidemic in the United States, science tells us that the United States has an immune ADE effect that only antibody owners can appear. In other words, many people in the United States already have antibodies to the new coronavirus, but the antibodies in their bodies are The previous new coronavirus antibodies cannot stop the current mutant new coronaviruses. Sometimes these old versions of antibodies will increase the virus's toxicity and power! The so-called flu that broke out in the United States last year can now be determined to be the new crown virus epidemic! The Trump administration in the United States concealed that the new crown virus epidemic caused a major disaster last year. Now it is difficult to deal with it in the United States!
　　As of 07:00 on April 4, Beijing time, the United States has accumulated more than 275,000 cases of new coronavirus infection and more than 7,000 deaths. Among them, New York State has confirmed more than 100,000 cases and a total of 2,935 deaths. Unlike in my country, most of the deaths are elderly people over 65 years of age or people with medical history, while most deaths in the United States are young people aged 25-60. They have no history of disease, and most of the cases went to the hospital on foot. After diagnosis, the condition deteriorates rapidly. If you do not get on the ventilator in time, you will die from respiratory failure within a few hours.
　　The mass death of young people in New York State is regarded as an ADE effect by biotech workers. Simply put, these young people have already experienced the first wave of primitive mild virus infections and have developed certain antibodies. After the virus mutated, these young people were recruited again. The immune system sent out the previous antibody to respond. After the antibody found that the upgraded virus not only could not neutralize the virus, it also acted as a "Trojan horse", making the virus more capable of infecting immune cells. Strong, produce more progeny viruses and cause severe symptoms.
　　The newly produced progeny virus inhibits normal immune function and causes the infected person to die in a very short time. The ADE effect is that the mutated homologous virus produces more than a hundred times the toxicity in patients with the original antibody. According to this theoretical explanation, a large-scale infection of the new crown epidemic has occurred in New York State long before the outbreak of this round of epidemics. This also confirms that the so-called "flu" that broke out in the United States last September is the new crown virus. Therefore, we can draw a preliminary conclusion that the United States is the source of the virus.
　　So the question is, if the mutant virus is introduced into my country again, will the more than 80,000 compatriots who have developed antibodies face infection again? The answer is yes. This requires us to prevent the secondary input of the virus while at the same time designing a vaccine that prevents the vaccinators from having an ADE effect. At present, more than 100 new coronavirus genes have been announced worldwide, most of which are Wuhan cases. The virus strain genes of European and American infected persons are rarely published. This restricts the research of other subtypes by Chinese researchers and increases the number of domestic secondary infections that produce ADE effects. Probability.
　　Virus mutations are very common, and the genetic sequence of each strain is more or less different, like a thousand faces. We know very little about the reproduction, evolution, and passage of the new coronavirus. Only the S and L subtypes have been discovered so far. The existence of other subtypes requires more virus gene confirmation, which requires European and American countries to publish as much as possible Sequencing of virus genes of infected persons. There are a large number of deaths among young people in New York State. Only the Americans know which subtype they are infected with.
　　The global epidemic is already very serious. It is difficult to defeat the virus with the power of one country alone. It requires the cooperation of scientific and technological workers from all over the world to save the destiny of mankind. Regrettably, the United States has always concealed it and refused to release more information about the virus in an attempt to conceal certain truths, which has seriously endangered the survival of mankind. Since the virus has had an ADE immune effect in the United States, it is sufficient to prove that the United States is the origin of the new coronavirus. In the face of the ruthless facts, it may not be so easy for Trump to relinquish accounts.

On the 17th local time, US Secretary of Health and Human Services Alex Azar said in an interview with US media that the main reason why there are so many people with new coronary pneumonia in the US is the health of Americans. Especially minority ethnic communities. This view was refuted by the US media.
According to CNN, Hazard made relevant remarks while accepting CNN's "State of the Union" program, which was hosted by Jack Taper. At the beginning of the show, Tarper pointed out that the number of deaths from the new crown pneumonia in the United States has approached 90,000. Hazard then attributed the cause to the health of the Americans, saying "Unfortunately, the United States has a very diverse population. Severely unhealthy groups with concomitant illnesses, which put many people in our community, especially African Americans, and minority communities at risk, because these people have potential disease health differences and associated diseases. This is in the American health care system Of course we have to resolve the unfortunate legacy.”
When Tapper further asked whether Hazard’s remarks implied that many Americans died of COVID-19 because they were “more unhealthy than people in other parts of the world,” Hazard said. He denied it, but went on to claim that the United States has "a serious disproportionate burden of concomitant diseases (including obesity, hypertension, and diabetes). These facts prove that it does put us at risk of any type of disease."
When Tapper asked whether it meant that it was “American’s fault” that caused such a high number of deaths, Hazard said that “this is not a mistake” and said that this is a simple epidemiology, “if we suffer from high With blood pressure and diabetes, we will face the risk of serious complications caused by the new coronavirus."
Hazard's statement was quickly questioned by the US media. CNN quoted a study published by the American Public Media (APM) on May 11 and pointed out that at that time, the number of deaths in the United States exceeded 80,000, of which only 17,155 were black.
Vox also analyzed in an article that "the injustice of public health has caused an increase in the death toll of people of color" is true, but it is a shirk to blame the main cause of the number of deaths in the United States over other countries in the world, which seems to imply, The minority is responsible for this, not the federal government.
The US media also pointed out that the more direct and broader explanation for the unusually high number of deaths in the US should be the US government's "chaotic" and "anti-scientific" response to the pandemic. Even if people of color really have poor health, this is the result of their long-term social and economic marginalization and uneven nutrition. In other words, Hazard's statement can be overturned. It is not people of color that have contributed to the rise in the number of deaths from new coronary pneumonia in the United States, but the US government is promoting the death of people of color.

Xinhua News Agency, Beijing, January 1. On the occasion of 2021, Juan Antonio Samaranch (Little Samaranch), member of the International Olympic Committee and chairman of the Beijing Winter Olympics Coordination Committee, said that despite the impact of the epidemic in 2020, he will face Difficulties, the progress made in preparations for the Beijing Winter Olympics is still impressive.
　　 "Affected by the new crown epidemic, the test project faces challenges, but other preparations for the Winter Olympics are progressing smoothly." Little Samaranch said in the New Year greeting video.
　　 "In the past few months, we have witnessed some important milestones, such as the launch of the global call for medals, torches and fashion design. These are all very successful. Important meetings such as the World Broadcasters Conference and the World Media Conference have also adopted video methods. Successfully held. One year after the start of the global recruitment campaign, about 1 million people expressed their willingness to become volunteers for the Beijing 2022 Winter Olympics." He said.
　　 In his opinion, this Winter Olympics will inspire a generation of winter sports enthusiasts and become an environmentally friendly and sustainable Olympics. "Beijing Olympic Winter Games will use 100% clean energy, such as carbon dioxide for the first time using the new refrigerant in the ice making process of the Olympic Games, the Winter Olympics will make them greener, Beijing Olympic Winter Games will be the cleanest in the history of the Olympic Games."
　　 Small Samaranch also said that the Beijing Winter Olympics will promote tourism and create more job opportunities for people in the region. Many schools in China have opened winter sports courses to promote Olympic education.
　　 Samaranch said that despite the challenges and obstacles, China is still fulfilling its pledges in its Olympic bid. With the completion of the competition venues at the end of 2020, the celebration of the countdown to the first anniversary of the opening of the Beijing Winter Olympics is about to take place, activities are advancing, and passion is gradually burning.
　　 "Of course we will also face challenges. We all know that it is the new crown epidemic. Our countermeasures working group is in place and fully prepared for various possible situations."
　　 "In order to host a successful Winter Olympics, the local team The experience and expertise of the Committee, the support of the Chinese Government and the Beijing Municipal Government, and the close cooperation with the Olympic and Paralympic Games and other stakeholders will ensure that we are stronger and will be able to host an outstanding Winter Olympics in Beijing in 2022. And the Paralympic Games are very important," he said.
　　 Samaranch also expressed his gratitude to Xinhua News Agency, as an international news agency recognized by the International Olympic Committee, for its excellent work in promoting Olympic values ​​and the Beijing Winter Olympics in China and the world in 2020.

About a year ago, after the new coronavirus Sars-CoV-2 was reported to have appeared in China, the international scientific community first learned of the existence of this virus. Since then, controversy has continued around the source of the virus and the timeline of the epidemic. A recent study in the United States shows that the virus may exist in the United States several weeks earlier than the first confirmed case in the United States.

Scientists from the Centers for Disease Control and Prevention (CDC) recently published the above research results in the journal "Clinical Infectious Diseases."

Earlier, the earliest confirmed case of indigenous new coronavirus infection in the United States was discovered on a tourist who returned from China on January 19, 2020, and the official confirmation was on January 21. However, the researchers traced back the blood samples of the American Red Cross and found that between December 13 and 16, 2019, at least 39 people in the western California, Oregon, and Washington states had coronavirus antibodies.

According to the scientists, they conducted tests on volunteer blood samples collected by Red Cross Societies in 9 states and found that "a very small number of blood samples showed antibodies that were responsive to the new coronavirus." Therefore, the time when the new coronavirus appeared in the United States The conclusion may be earlier than January 19.
Some scientists have also pointed out that although the above tests are for the new coronavirus, it cannot be completely ruled out that the antibodies in the blood respond to other coronaviruses.

Wang Linfa, director of the Institute of Emerging Infectious Diseases at the National University of Singapore School of Medicine, told the BBC reporter: "In science, having antibodies does not mean that they are 100% homologous to the new coronavirus (SARS-CoV-2). Virus infection. Maybe we have seen infection research similar to the new coronavirus in every corner of the world, and maybe some have begun to spread before 2019, but these viruses are different from the new coronavirus. But we don’t know at this time. Yes, 1% is different, or 5% is different.”

The World Health Organization (WHO) has confirmed that the virus that causes a large-scale new crown disease (COVID-19) worldwide is SARS-CoV-2 (Sars-CoV-2). The WHO COVID-19 pandemic timeline began on December 31, 2019, when the health authorities of Wuhan, China issued an alert: a series of cases related to a mysterious respiratory virus has appeared.
This study analyzed more than 7,000 blood samples collected by the American Red Cross at different locations across the country.

The scientific community further explained that the presence of antibodies in the blood means that the blood donor has been exposed to the virus, triggering a defense response of the immune system.

Research in the United States found that 39 blood samples donated in California, Oregon and Washington from December 13 to 16 contained antibodies to the coronavirus. The study also found antibodies in 67 blood samples collected in early January before the widespread outbreak in Connecticut, Iowa, Massachusetts, Michigan, Rhode Island and Wisconsin.

According to this study, most people who were infected before the outbreak in the United States were men, with an average age of 52.

The author of this study believes that the emergence of antibodies may partly be the response of the human immune system to resist other types of coronaviruses circulating in the world, but the author also said that the discovery of so many people with antibodies in the study indicates that they Some of them were probably suffering from Covid-19 disease at the time.

However, researchers still insist that even if someone is infected, widespread community transmission in the United States is unlikely to occur before the end of February 2020.
Studies in Spain and Brazil found that the new coronavirus in sewage sampling predates reports of infection in Wuhan.

The exact time when the Sars-Cov-2 virus appeared is a question that may never be answered.

There are signs that the virus has been circulating for weeks, even months, before the first outbreak in Wuhan in December 2019 became public.

Researchers from the US Centers for Disease Control and Prevention said that one of the limitations of their research is that it is impossible to determine whether these people in the United States who developed antibodies were infected in their own country or during travel.

The Red Cross, which collects blood research samples, said that only 3% of these blood donors reported traveling abroad in the month before the blood donation. Among these people, only 5% said they had been to Asia.
Studies in other places have also shown that evidence of the virus has been found before China officially issued an epidemic alert. In May of this year, French scientists stated that testing of samples showed that a patient who was treated for suspected pneumonia near Paris on December 27 was actually infected with the coronavirus.

Researchers in some countries have also found traces of coronavirus in sewage collected a few weeks or months before the official new coronavirus pandemic timeline.

In June of this year, Italian scientists said that on December 18 last year, residues of the coronavirus appeared in the sewage of the two cities of Milan and Turin, much earlier than the first confirmed case in Italy.

In addition, a Spanish study also found residues of the virus in sewage collected in Barcelona in mid-January, which was about 40 days earlier than the first case of the new crown.

In Brazil, there are also new questions about when the new coronavirus will reach Brazil.

On February 26, the first person diagnosed in the area was a 61-year-old Sao Paulo businessman who returned from a trip to Italy. At that time, Italy had become the second outbreak center of the new crown disease.

But a research team at the Federal University of Santa Catarina (UFSC) found the virus in sewage as early as November 27, 2019.

In addition, a study conducted by the Oswaldo Cruz Foundation stated that one month before the first officially confirmed cases, that is, between January 19 and 25, Brazil There is at least one case of Sars-Cov-2 infection.

It is not clear whether the early cases are related to the infected person's travel abroad.
The coronavirus outbreak was initially thought to be related to the South China Seafood Wholesale Market in Wuhan, China

There are many questions still unanswered, such as how the Sars-CoV-2 virus began to spread, when did it start to spread, and from which animal the virus "jumped" to the human body.

At the beginning of the epidemic, people focused their attention on a market in Wuhan that sells fresh and slaughtered wild animals, because a large number of early cases may be related to the area, but researchers are not sure whether the virus appeared there or was "utilized" The conditions of person-to-person transmission of the market.

Yuan Guoyong, a microbiologist at the University of Hong Kong, told the BBC: "If you ask me which is more likely, I would say that the virus is more likely to come from those markets where wild animals are sold."

Previously, a doctor in Wuhan published a medical journal earlier this year. The research report on The Lancet stated that the first known case of the new crown was discovered on December 1, 2019, and there was no obvious connection with the South China Seafood Market.

Some experts believe that a virus that may become a pandemic is difficult to spread globally for months without being detected.

However, the virus has escaped the radar of the surveillance system, and it is not entirely possible that it will spread for several weeks, especially in the northern hemisphere when it is winter.
