Chinese government researchers isolated more than 2,000 animal viruses, including deadly bat coronaviruses, and carried out scientific work on them just three miles from a wild animal market identified as the epicenter of the COVID-19 pandemic.
Several Chinese state media outlets in recent months touted the virus research and lionized in particular a key researcher in Wuhan, Tian Junhua, as a leader in bat virus work.
The coronavirus strain now infecting hundreds of thousands of people globally mutated from bats believed to have infected animals and people at a wild animal market in Wuhan. The exact origin of the virus, however, remains a mystery.
Reports of the extensive Chinese research on bat viruses likely will fuel more calls for Beijing to make public what it knows about such work.
