origin the coronavirus
Answers
Answer:
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.
The earliest known person with symptoms was later discovered to have fallen ill on 1 December 2019, and that person did not have visible connections with the later wet market cluster. Of the early cluster of cases reported that month, two-thirds were found to have a link with the market.
