A new genetic analysis of animals in the Wuhan market in 2019 may help find COVID-19′s origin

By Maria Cheng, Associated PressShopping mall workers undergo a COVID-19 swab test during the opening at the Paragon shopping mall in Bangkok, Thailand, Wednesday, Sept. 1, 2021.

Michael Worobey, one of the new study’s authors, said they found which sub-populations of animals might have transmitted the coronavirus to humans. That may help researchers pinpoint where the virus commonly circulates in animals, known as its natural reservoir. Mark Woolhouse, a professor of infectious diseases at the University of Edinburgh, said the new genetic analysis suggested that the pandemic “had its evolutionary roots in the market” and that it was very unlikely COVID-19 was infecting people before it was identified at the Huanan market.
