Opinion | SARS-CoV-2: A preprint provides ammunition to conspiracy theories about virus origin

R. Prasad In a preprint that was posted on Research Gate (but now available only in the Wayback Machine), two researchers — Botao Xiao and Lei Xiao —from Chinese institutions have claimed without attributing scientific evidence, that the “killer coronavirus probably originated from a laboratory in Wuhan”. The claim has provided much ammunition to the conspiracy theory that is already circulating on the Internet.The authors are from South China University of Technology in Guangzhou and Wuhan University of
