What happened when a large number of Americans revealed that they had arrived in COVID-19?

According to a recent survey, more than 1000 users on social media Twitter said that they or their family and friends were infected with COVID-19 virus in 20 19, 12 or even earlier. Among them, at least more than 100 real-name users described the infection experience seriously, and the symptoms they described were very close to those of COVID-19.

"My wife and doctors are convinced that I got COVID-19 in 20 19 10/0. It's terrible. They didn't know what it was. I was isolated in the intensive care unit for 10 days, and my blood oxygen content was low. X-rays (lungs) are like broken glass. They can't identify viruses and bacterial pneumonia after many tests. " Jamie Kettenhoffen, a resident of Washington, wrote in a tweet on February 22, 2020.

Another American user, James Krutoks, wrote in June 5438+February 65438+August 2020: "It is estimated that I got COVID-19 in June 2065438 +065438+2009 10 or June 65438+February 2020. Severe recurrent fever, respiratory problems (I had to go to the emergency room twice, wearing an atomizer every time), steroids and X-rays found a lung problem-the most serious disease in my life. I feel that if I don't go to the emergency room, I won't wake up from sleep. "

"My son suffered from viral respiratory diseases and pneumonia in both lungs in June and February of 5438. He looks hardly ill, but in fact he is very ill. He ended up in this hospital. The blood sample donated by 20 19 showed COVID-19 antibody, and now I 100% confirm that he has COVID-19. He is fine now, which happened in 65438+February last year. " This is February 65438+February 2020 1 1, a tweet from a female user named Chersi in Detroit, USA.

Recently, the website of Nature magazine reported that researchers from the US Department of Agriculture analyzed some serum samples from white-tailed deer in the northeastern United States, and found that COVID-19-related antibodies existed in white-tailed deer samples of13. Among the samples collected in 20 19 years, 1 sample detected relevant antibodies, indicating that it has been infected with COVID-19. The first case of COVID-19 officially reported by the United States was June 65438+1October 265438+1October 2020.

On June 30th, 2020, 165438+ researchers from the US Centers for Disease Control and Prevention reported in the bimonthly issue of Clinical Infectious Diseases that they had tested the American Red Cross from February 20th19th13rd to October 20th120th.

Experts believe that early suspected cases and early clues found in animals and the environment should be the focus of the next stage of virus traceability. In an interview with the media, Liang Wannian, the Chinese leader of the China-WHO Joint Traceability Research Expert Group in COVID-19, suggested that WHO should evaluate and analyze early suspected cases and early evidence found in animal and environmental studies to determine the scientific validity and reliability of existing evidence.
