The principal hypothesis for the origin of COVID-19 is that it became infectious to humans through a natural spillover event (zoonosis). That it became infectious to humans through escape from a laboratory where it was being studied is a minority position. The available evidence supports zoonosis.
From the early outbreak of the COVID-19 pandemic, rumors and speculation arose about the possible lab origins of SARS-CoV-2, the causative agent of the COVID-19 disease.. Different versions of the lab origin hypothesis present different scenarios in which a bat-borne progenitor of SARS-CoV-2 may have spilled over to humans, including a laboratory-acquired infection of a natural or engineered vir

Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
