Covid first emerged in Wuhan, China, before spreading to the rest of the world. Like SARS, it is derived from from viruses that evolved naturally in bats.
It is possible that Covid leaked from a lab in Wuhan that was doing "gain of function" research on natural coronaviruses[1]. This theory has recently moved from fringe to something taken seriously by authorities[2].
Chinese state-owned media claims that Covid-19 was intentionally created by the US.[3]
