Answer:

good questis

Explanation:

there is not a clear way of the origin

Here’s what I know about the virus that was first detected in Wuhan, China, in late 2019 and has set off a global pandemic. Some wet markets sell wild or banned species like cobras, wild boars, and raccoon dogs. Crowded conditions can let viruses from different animals swap genes. Sometimes the virus changes so much it can start to infect and spread among people. Scientists first identified a human coronavirus in 1965. It caused a common cold. Later that decade, researchers found a group of similar human and animal viruses and named them after their crown-like appearance.
