SARS-CoV-2 made the dive to humans at one of Wuhan’s open-air “wet markets.” They’re where consumers acquire fresh meat and fish, including animals that are eliminated on the spot.

Some wet markets offer wild or prohibited varieties like cobras, wild boars, and raccoon dogs. Crowded problems can allow infections from different animals to swap genes. Often the disease changes a lot. It can start to contaminate as well as spread among individuals.

Still, the Wuhan market didn’t offer bats at the time of the breakout. That’s why early uncertainty additionally fell on pangolins, also called scaly anteaters, which are marketed illegally in some markets in China. Some coronaviruses that infect pangolins resemble SARS-CoV-2.
