Novel coronavirus pneumonia is actually a coronavirus infection pneumonia, and there are a total of 6 coronaviruses that are currently capable of infecting humans. This novel coronavirus pneumonia is currently the seventh coronavirus. The origin of the coronavirus has not yet reached a particularly clear conclusion, but when researchers compared the sequence of the novel coronavirus with other known viral sequences, they found that the sequence of this novel coronavirus and the sequence of the coronavirus in wild animals such as bats have a very high homology, suggesting that this novel coronavirus may come from wildlife in the wild. However, it has not been particularly clear to conclude which wildlife the novel coronavirus comes from. Content source: Dr. Arigato
