A fever of 37.8°C may not necessarily be caused by a novel coronavirus infection, but may also be caused by bacteria or common viruses, such as rhinovirus and influenza virus, and cannot be determined by the temperature alone. To confirm the diagnosis of novel coronavirus fever, the first requirement is that the patient has an epidemiological history, that is, the patient has been to the infected area or has had close contact with people in the infected area. In addition to fever, the patient also has respiratory symptoms such as cough and malaise, and a positive laboratory swab test for viral nucleic acid, which is the only way to consider fever caused by novel coronavirus infection.
