According to research, the natural host of novel coronaviruses is bats, and the intermediate hosts are usually wild animals, and people are often infected with novel coronaviruses through close contact with or consumption of wild animals carrying the virus. Infected patients usually have common respiratory symptoms such as fever, malaise, cough, or gastrointestinal symptoms such as diarrhea. The novel coronavirus can be transmitted through respiratory droplets, contact transmission and lead to mass infection, so the main focus of the novel coronavirus is prevention.
