The virus was first officially reported in China in late December 2019. French researchers analyzed 10,000 blood samples, of which at least 44 showed antibodies against the coronavirus. Seven of these samples were taken in November 2019 and three in December of the same year.
The authors emphasize that there may be false positives among these samples. However, it is impossible for all the results to be wrong.
Recently, scientists have repeatedly come across information that the virus was already circulating even before China notified the World Health Organization (WHO). Although the new study does not provide any new and definitive evidence, in any case it confirms this conjecture.
As early as August 2020, French researchers in Alsace evaluated photos of patients’ lungs and discovered a case in mid-November 2019 showing COVID-19.
The question of the origin of the virus is complicated. Among other things, China claims that the virus may have first spread to other countries and possibly entered the People’s Republic with imported frozen food.
A panel of experts sent to China by the WHO could not identify the origin of the virus earlier this year.
