New coronary pneumonia is currently transmitted mainly by droplet transmission, contact transmission, and aerosol transmission may occur under certain special conditions, such as when performing specialized medical operations such as clinical tracheal intubation. Properly worn masks are sufficient to protect the general public from infection if they are under routine clinical care, general working and living conditions, and there is no need to be overly concerned. It is recommended to pay close attention to the health status of family members during an outbreak. If symptoms such as fever or cough occur, they should consciously avoid contact with others, wear a good mask and go to the nearest fever clinic as soon as possible and cooperate fully with treatment.
