After a patient is exposed to the new coronavirus, the incubation period is as short as 1 day, the longest is now reported to be 24 days, and it is usually 3-7 days. If exposed to the new coronavirus, the virus can multiply rapidly in the organism to cause disease, resulting in fever and cough in the patient. Respiratory symptoms such as sneezing, runny nose, sore throat pain time is about 4 days, usually about 7 days can appear lung infection, manifested as dyspnea, wheezing, fever increase, or sepsis, refractory acidosis, coagulation disorders, and other more serious conditions. From infection to the appearance of symptoms is the patient’s incubation period, usually 1-7 days, not more than 14 days.
