The incubation period of coronavirus can be transmitted to others. The incubation period of novel coronavirus infection in patients is around 1-14 days, usually 3-7 days. During the incubation period of novel coronavirus, usually the patient does not have any clinical symptoms, but the carrier of the virus may carry and excrete the virus in the upper respiratory tract, which can be transmitted to normal healthy adults through close contact or respiratory droplets and other forms. Therefore, if there is a possibility of novel coronavirus infection, early isolation and early treatment are recommended. At the same time, healthy people are advised to wear masks when going out, reduce access to public places, keep indoor and outdoor air circulation, as well as wash hands regularly, increase nutrition and strengthen the body’s resistance, etc., so as to reduce and prevent the possibility of novel coronavirus infection.
