The etiology of the novel pneumonia is caused by infection with a novel coronavirus, but the source of the novel coronavirus is unclear. It is currently speculated that the natural host may be a bat and the intermediate host may be a snake. More than 100 species of SARS coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus and Ebola in 2003 are known to have originated from bats. But it is not necessarily bats that transmit them. Bats can transmit viruses to wild animals such as civets, snakes, rabbits, etc. Humans who eat such intermediate hosts can also be infected with coronaviruses, parasites and other diseases carried by the animals. Therefore it is better not to eat wild animals and keep your natural health and body healthy.
