Novel coronavirus can be tested by the latest nucleic acid test kits and if the nucleic acid test is positive, the diagnosis is confirmed as an infected person. The incubation period for novel coronavirus pneumonia ranges from 2 to 12 days, with an average of 7 days. After recent exposure to a suspected or confirmed case, you should isolate yourself for 14 days. If cough and temperature exceeds 37.3°C occur during the isolation period, you should go to a nearby sentinel hospital for screening and confirmation. Fever is a typical symptom of novel coronavirus infection, and the doctor should be accurately informed of the contact history with the suspected or confirmed patient at the time of consultation.
