Fever is the most common symptom in patients with novel coronavirus pneumonia because the three most common symptoms of novel coronavirus pneumonia are fever, dry cough, and malaise. 37.5°C is only a low fever, but low fever may also be severe or critically ill patients, and the patient should go to the fever clinic of the hospital in time. Combine clinical symptoms, epidemiologic history, exposure history, and nucleic acid testing to make a definitive diagnosis. If the nucleic acid test is positive, it can be regarded as a confirmed case, and isolation and symptomatic treatment should be taken promptly. If the fever is only 37.5℃ and there is no other relevant evidence of infection with novel coronavirus pneumonia, only close observation is needed. Of course, many other illnesses can raise body temperature, and most cases of novel coronavirus pneumonia are characterized by high fever lasting more than 72 hours. Source: Dr. Yurai
