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.
The FBI concluded with "moderate confidence" that COVID-19 may have been created in a laboratory, based in part on genomic analysis conducted by scientists at the National Center for Medical Intelligence. [98] On 20 March 2023, the COVID-19 Origin Act of 2023 was signed into law. On June 23, 2023, the Biden administration released its report ...
Natural selection produced the human coronavirus by mutation in humans. The spike protein of SARS-CoV-2 interacts with furin, an enzyme found in human cells. Furin-like sites are present in other viruses such as HIV and Ebola virus, but not in bat or pangolin coronaviruses, suggesting that the specific furin interaction developed only in humans.

SARS-CoV-2, the causative agent of COVID-19, was first introduced to humans through zoonosis (transmission of a pathogen to a human from an animal), and a zoonotic spillover event is the origin of SARS-CoV-2 that is considered most plausible by the scientific community.
Conspiracy theories and misinformation about coronavirus damage society in a number of ways.
Most Americans now have some immunity against the virus, either by vaccination, infection or both. But there have been some rare cases in which certain unvaccinated people seem to have been able ...
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. The Centers for Disease ...
