The Covid-19 virus may have originated from humans, a Chinese scientist has claimed.
The genetic sequences of viral samples taken from the Huanan Seafood Market in Wuhan – thought to be the ground zero site of the pandemic – were “almost identical” to those of patients infected with the coronavirus, suggesting that Covid-19 may have originated from humans, said Tong Yigang of the Beijing University of Chemical Technology.
Speaking at the same event, a Chinese Center for Disease Control and Prevention researcher, Zhou Lei, called for global scientific collaboration in tracing the origins of the virus, saying that the site where Covid-19 was first discovered was not necessarily where it originated. China has in the past been heavily criticized for blocking international investigations into the origins of the virus.
