[O]n Fox News and social media, a dangerous conspiracy theory about the origin of the health crisis won’t die.
There are two main versions of the rumor, and they have one common thread: that the coronavirus, SARS-CoV-2, originated in a level 4 (the highest biosafety level) research laboratory in Wuhan.
In one version of the rumor, the virus was engineered in the lab by humans as a bioweapon. In another version, the virus was being studied in the lab (after being isolated from animals) and then “escaped” or “leaked” because of poor safety protocol.
But already, virologists who’ve parsed the genome and infectious disease experts who study coronaviruses say they have enough evidence the virus is brand new and came from nature. A large group of them, citing genome analyses from multiple countries, recently affirmed in The Lancet that the virus originated in wildlife.
“Conspiracy theories about manmade viruses are not new. We saw this with HIV — the rumor that the US made it and introduced it into Africa. But they are really dangerous kinds of things to get spread around,” Gerald Keusch, a professor of medicine and international health and associate director of Boston University’s National Emerging Infectious Diseases Laboratories, told Vox.
