The origin of COVID-19, caused by the SARS-CoV-2 virus, is most likely zoonotic, meaning it originated from animals. The first known outbreak started in Wuhan, China, in late 2019, with early cases linked to the Huanan Seafood Wholesale Market where live wild animals were sold. The scientific consensus is that the virus was transmitted from animals (probably bats or an intermediate host) to humans, although there is also discussion about a possible laboratory leak, but this hypothesis lacks definitive evidence as of now. Key points include:

• SARS-CoV-2 is genetically similar to viruses found in bats.
• Early cases were concentrated around the Wuhan market, which sold wildlife.
• Genetic studies show the virus's diversity can be traced to the market environment.
• The lab-leak theory has been investigated but remains less supported by current evidence, with some intelligence agencies considering both possibilities plausible.

Thus, the global scientific view leans strongly towards a natural animal origin, potentially from wildlife sold at the market, rather than a laboratory creation or intentional release.
