How did the coronavirus disease start?


Several of the early cases had visited Huanan Seafood Wholesale Market and so the virus is thought to have a zoonotic origin. The virus that caused the outbreak is known as SARS‐CoV‐2, a newly discovered virus closely related to bat coronaviruses, pangolin coronaviruses, and SARS-CoV.
The scientific consensus is that COVID-19 has a natural origin. The probable bat-to-human infection may have been among people processing bat carcasses and guano in the production of traditional Chinese medicines.
