COVID-19, caused by the coronavirus, is a zoonotic disease, meaning it originated from an animal. The source of the outbreak is believed to have been a "wet market" in Wuhan, China, that sold live and dead wildlife and domestic animals, along with other foods for human consumption. Such markets can be a living petri dish, with viruses shed by stressed animals warehoused together mixing with other bodily fluids in unhygienic conditions. When these often new or unknown viruses jump to people, the results can be catastrophic.
Although the origin of severe acute respiratory syndrome–coronavirus 2 (SARSCoV-2)—the virus that causes coronavirus disease 2019 (COVID-19)—has not been identified, it is clear that China's wildlife market played an important role in the early spread of the disease
Among threatened wildlife species, those with population reductions owing to exploitation and loss of habitat shared more viruses with humans
Shi and her American collaborators have shown that in a laboratory environment bat coronaviruses can jump directly to humans.
