Fever is the most prominent and common symptom of novel coronavirus infection, and the temperature of fever varies among patients. The vast majority of patients do not have a high fever, usually below 38.5°C, but some patients may have a high fever of 39°C or higher. Some patients have mild symptoms and may not even have significant fever symptoms. For people with a history of significant epidemiological exposure, if they develop fever or other uncomfortable symptoms, it is best to go to a fever clinic at any hospital and ask a doctor to perform pathogenic testing to confirm whether they are infected with the virus. Once the diagnosis is confirmed, the person should be promptly treated in isolation at a designated hospital to avoid cross-infection or delayed illness.
