The incubation period of novel coronavirus infection is usually 1 to 14 days. Novel coronavirus infection is a respiratory infection, and it usually takes a certain period of time from exposure to the novel coronavirus to the onset of clinical symptoms, which is the incubation period of novel coronavirus infection. Novel coronavirus infection usually develops within 1 to 14 days after exposure to the virus, which means that the incubation period is usually 1 to 14 days. For people with an epidemiologic history of novel coronavirus pneumonia, isolation for two weeks with close monitoring and nucleic acid testing is usually required to assess the presence of novel coronavirus infection. In addition, after two weeks, home isolation and health surveillance may still be necessary.
