The SARS-Co" coronavirus was in the United States earlier than the known weeks. A new study analyzed blood donation activities from December to early January 2019, which showed that the time of the coronavirus infection in the United States was earlier than previously thought. According to a new government report published on Monday, the emergence of the coronavirus in the United States was weeks earlier than scientists and public health officials had previously thought, and before the Chinese case was publicly identified.
The virus and the disease COVID-19 that it causes were first discovered in Wuhan, China in December 2019, but it was not until around January 20 that a traveler returning from China confirmed a COVID-19 case for the first time, and it was discovered in the United States
However, new findings published in the journal Clinical Infectious Diseases indicate that the coronavirus (formally known as SARS-CoV-2) infects people even earlier in the United States. "
V-2 infection may appear in the U.S. in December 2019
