The likelihood of being infected with novel coronavirus pneumonia at home is low because patients with novel coronavirus pneumonia must have a history of epidemiology in the infected area, have been in close contact with people in the infected area, and the novel coronavirus is transmitted mainly through respiratory droplets and close contact. There is no epidemiological history at home, and the transmission of infectious diseases is blocked, so the possibility of being infected with novel coronavirus pneumonia is unlikely. It is important to keep indoor and outdoor air circulation, wash hands frequently, increase nutrition, and enhance physical fitness in order to improve the immune function of the body, which can play a role in preventing the occurrence of the disease.
