SARS-CoV-2

The first case of the SARS-CoV-2 that causes COVID-19 was a market vendor at Huanan Market in China's Wuhan, said a US study on November 18. So far, it was thought that an accountant was the source of the virus and his symptoms were found on December 16. However, the study reported that, before the accountant, vendors at the market were diagnosed with a similar ''illness onset 11 December''.
