A body temperature of 37 degrees 2 generally does not require isolation. However, as this is a special period of the epidemic, it is necessary to take into account the epidemiologic history of the patient, as well as the clinical manifestations and nucleic acid test results, to make a comprehensive judgment, and it is not recommended to determine the need for isolation solely by body temperature. If the patient comes from or passes through an infected area and has a history of contact with infected people, with close monitoring of body temperature, it is also necessary to conduct a new coronavirus nucleic acid test in time to further investigate whether the patient is infected with the new coronavirus, and then decide whether isolation is necessary. If there is a history of contact with patients with novel coronavirus pneumonia, asymptomatic infected persons, close contacts, or persons in contact with areas infected with novel coronavirus with a temperature of 37°C2, home isolation or centralized medical isolation is recommended, and further relevant tests should be performed to detect the presence of novel coronavirus. If there is no history of novel coronavirus exposure and no obvious clinical manifestations, isolation is not required and temperature changes can be monitored. The degree of fever is categorized into 4 grades, low fever: body temperature at 37.3-38℃; moderate fever: body temperature at 38.1-39℃; high fever: body temperature at 39.1-41℃; and ultra-high fever: body temperature >41℃. If the fever, or accompanied by cough, cough sputum, abdominal pain, diarrhea and other symptoms, should be timely hospital consultation.
