In a calm state, the axillary temperature of 36℃-37℃ is the normal body temperature, which is not fever, while fever is the body temperature over 37.3℃. After the novel coronavirus infects human body, patients mostly have fever as the first and main symptom, but some patients have mild symptoms and can have no obvious fever, so the body temperature of 37℃ cannot indicate that the body has been infected with novel coronavirus. Patients with a clear history of epidemiological exposure are advised to isolate themselves at home. If symptoms such as increased body temperature, malaise, dry cough, loss of energy, loss of appetite, diarrhea and respiratory distress gradually appear subsequently, they should be promptly treated at fever clinics around the world.
