According to a study published in the journal Clinical Infectious Diseases by researchers at the Centers for Diseases for Diseases and Prevention on November 30, according to tests for blood donation samples from residents in nine states in the United States, the novel coronavirus may have appeared in the United States as early as mid-December 2019. This is a month earlier than the first confirmed case in the United States, which was officially reported in the United States.
106 of 7,389 blood donation samples were antibodies
In this study, the American Red Cross provided 7,389 blood donation samples collected by residents of nine states in the United States from December 13, 2019 to January 17, 2020 to the U.S. Centers for Disease Control and Prevention. The results showed that COVID-19 antibodies were found in 106 blood samples, of which 39 samples were collected from California, Oregon and Washington from December 13 to December 16 last year, and 67 blood donation samples from December 30 last year to January 1 this year. Collected from Massachusetts, Michigan, Wisconsin and other places on the 7th.
According to researchers from the Centers for Disease Control and Prevention, these dates date predate the first confirmed case reported in the United States in January this year.
Researchers from the U.S. Centers for Disease Control and Prevention wrote in the report that the latest findings indicate that “coronavirus cases in the United States may have appeared in December 2019, earlier than previous findings”.
In December last year, I or my family were infected with the novel coronavirus.
This study has attracted the attention of many netizens on social media. Many Americans left messages saying that as early as December last year, or even earlier, they or their families had symptoms similar to COVID-19, and some even used ventilators.
Some American netizens said:
“After learning about the symptoms of COVID-19, I think I got it last December. I have many other symptoms, although I don’t remember losing my taste.”
“The four people in our family were very ill after attending a wedding last December. Everyone has symptoms similar to COVID-19 and it took a long time for the symptoms to disappear.”
“I knew so. Because my aunt and her friend fell ill when they went shopping the week before the public holiday last December. They were all hospitalized, and my aunt stayed for a week. After three months on a ventilator, her friend also went to a rehabilitation center to take oxygen.
“I’m sure I got the novel coronavirus in mid-12 of 2019. At that time, I had a fever for 13 consecutive days, but I was diagnosed with viral pneumonia.
“I’m sure I got the coronavirus last November.”
“We didn’t realize that the coronavirus was in that time. It didn’t spread at first, so people didn’t pay attention to it.”
In addition to American netizens, some netizens from other countries said that they had symptoms similar to the novel coronavirus in December last year.
“I’m glad that what I experienced last December and January was finally reported by scientists. I’m pretty sure I got the coronavirus back then.”
“The same is true in Ethiopia, early December (last year)! Even without this study, many people have already reported the same symptoms as the novel coronavirus.”
Several studies have found that the novel coronavirus has spread around the world last year.
Previously, some American studies said that the novel coronavirus may have spread in Los Angeles before the first confirmed case of the novel coronavirus was officially reported in the United States. Reporting the latest report of the Centers for Disease Control and Prevention on November 30, the Wall Street Journal also pointed out that research further showed that the virus had spread in many parts of the world long before public health departments and researchers realized the existence of the novel coronavirus. For example, France has previously found that a patient admitted to the hospital on December 27 last year had contracted the novel coronavirus.
Infection cases appeared in Paris at the end of December last year
On May 3 this year, Coen, the head of the intensive care unit of the Jean-Virtier Hospital in the northeastern suburb of Paris, France, said in the French media that after re-testing the viral nucleic acid test samples of 24 previous pneumonia patients, one male patient admitted to the hospital on December 27 last year was found to be infected with the novel coronavirus. This shows that the Paris region of France had a new coronavirus case at the end of December last year.
Coen said that the male patient had been repeatedly checked to confirm that he was suffering from COVID-19 at that time. This case appeared nearly a month earlier than the imported case first confirmed by the French Ministry of Health on January 24.
Italian research shows that blood detected antibodies against COVID-19 last year.
According to a study recently published by the Italian media on November 15, the National Institute of Oncology in Milan, Italy, found antibodies against the novel coronavirus in some blood samples collected by the residents last September, which means that the novel coronavirus spread in Italy well before February this year. Month. The paper said that the National Oncology Institute of Milan recruited 959 volunteers to participate in a lung cancer test between September 2019 and March 2020. After the outbreak of COVID-19, researchers tested the preserved blood samples for COVID-19, and the results showed that 111 of the 959 samples were positive.
Lead author of the paper Professor of Public Health at the University of Siena Montomory: This is a solid scientific conclusion we have, from which we can infer that the novel coronavirus had spread in Italy and even Europe by the end of September last year.
