Remember my tweet 18 days ago about a South China University of Technology study? The study concludes that “the killer coronavirus probably originated from a laboratory in Wuhan.” Now China clamps down on further research on the genesis of the deadly virus https://www.theguardian.com/world/2020/apr/11/china-clamping-down-on-coronavirus-research-deleted-pages-suggest

The study said the virus likely escaped by accident from either Wuhan Center for Disease Control or Wuhan Institute of Virology. State-run China Daily in 2018 called the latter "Asia's largest virus bank." It deleted its 2018 tweet—screenshot below—soon after I cited it recently.
