Novel coronavirus pneumonia broke out around the end of December 2019 in Wuhan, Hubei province. Novel coronavirus pneumonia is a respiratory infectious disease that can be spread by droplet transmission and contact transmission, as well as by aerosol transmission. Novel coronavirus pneumonia belongs to category B infectious diseases, but strict prevention and control should be carried out according to category A infectious diseases, because the novel coronavirus was first discovered in Wuhan, but gradually spread to the whole country and even international outbreaks of novel coronavirus pneumonia. Therefore, proper prevention and control and normalization of epidemic prevention are the most important things to be done in China now. The main prevention and control of novel coronavirus pneumonia is to wear a mask, go to fewer places where people gather, do hand disinfection and hand hygiene, and avoid going to places where cases occur.
