Novel coronavirus pneumonia is caused by a coronavirus that emerged at the end of 2019, and the source of the virus is not yet conclusive. Based on extensive research by scientists and scholars in China and around the world, it is believed that the novel coronavirus originated from wildlife, with the Chinese chrysanthemum-headed bat being the most likely source. The novel coronavirus is the seventh coronavirus to infect humans to date and can be transmitted continuously from person to person, mainly through respiratory droplet transmission and contact transmission. In addition, the virus can cause various respiratory symptoms in humans, and the elderly and those with underlying diseases are in critical condition and have a high mortality rate.
