Novel coronavirus pneumonia is an infectious disease, and the so-called infectious disease has an infectious source and a transmission route. New coronavirus pneumonia is characterized by a relatively high level of infectiousness, and current research suggests that its ability to be transmitted is basically a patient passing at least 2-3 patients. Transmission is mainly through the following ways: 1. Transmission through respiratory droplets. Patients with viral infection in the lungs, the virus with the spray droplets infect others, this is the most common way. For the prevention of this way need to wear a mask, try to maintain a certain distance, droplets generally do not exceed 2 meters, so try to maintain a certain distance; 2, contact transmission, that is, droplets fall to the table, door handles, other people touch touch the table or handle, hands are infected and touch the nose, eyes, mouth, through the mucous membrane can also be related to the infection. So these two ways are very important ways of transmission. If you want to avoid being infected, you need to interrupt these two ways, and you need to wear a mask, wash your hands frequently, and disinfect, so that the transmission route will be interrupted.
