For adults, a body temperature of 37.1°C is not considered a fever. A body temperature above 37.3°C can be called a fever, while below 37.3°C is the normal range. If the body temperature of adults is 37.1℃, it is also necessary to observe whether there are other symptoms, such as sore throat, cough, phlegm or chest tightness, dizziness, generalized, weakness and other manifestations. If the clinical manifestations are more serious, it is also necessary to improve the blood routine and inflammatory markers, and if necessary, it is also necessary to improve the chest CT examination for clarification. If there are obvious symptoms of discomfort, it is necessary to measure the body temperature regularly. Observe whether the temperature is high, and if necessary, medication, such as antiviral drugs, should be administered. If the blood test results indicate a high temperature, additional antibiotics may be required.
