Apparently China's disease-control center had done a great deal of investigating of the Wuhan market, a WHO team member told the New York Times:
They'd actually done over 900 swabs in the end, a huge amount of work. They had been through the sewage system. They'd been into the air ventilation shaft to look for bats. They'd caught animals around the market. They'd caught cats, stray cats, rats, they even caught one weasel. They'd sampled snakes. People had live snakes at the market, live turtles, live frogs. Rabbits were there, rabbit carcasses... Animals were coming into that market that could have carried the coronavirus. They could have been infected by bats somewhere else in China and brought it in. So that's clue No. 1... Some of these are coming from places where we know the nearest relatives of the virus are found. So there's the real red flag...
There were other markets. And we do know that some of the patients had links to other markets.
