37.5℃ is not necessarily a novel coronavirus infection. To clarify whether it is a novel coronavirus infection, we need to have epidemiological history, i.e. whether we have been to the infected area or whether we have had close contact with people in the infected area, and also whether there are clinical respiratory symptoms such as fever, cough and malaise, whether there are imaging changes in chest CT, and whether there are dynamic changes in laboratory and blood routine, and also whether the patient’s throat swab is nucleic acid test Positive. If the above conditions are met, it is clear that it is a novel coronavirus infection, so a simple 37.5℃ is not necessarily a novel coronavirus infection.
