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.
Tong, who was speaking at a press conference held by the Chinese State Council regarding research into the origin of the virus, said more than 1,300 environmental and frozen animal samples had been taken at the market between January 2020 and March 2020, and researchers had isolated three strains of virus from the environmental samples.
