37.4 ℃ does not necessarily belong to the new coronavirus pneumonia, the new coronavirus pneumonia is required to do nucleic acid testing to be clear, the normal adult axillary body temperature is 36 ~ 37 ℃, clinically, the temperature between 37.3 ~ 38 ℃ is known as low fever. There are many causes of low-grade fever, including respiratory tract infections and non-infectious diseases. Respiratory tract infections such as colds, pharyngitis, laryngitis, tonsillitis, bronchitis, pneumonia, etc., can lead to a low fever of 37.4 ℃. Non-infectious diseases such as rheumatism, rheumatoid rheumatism, endocarditis, and connective tissue diseases can also cause the temperature to rise to 37.4°C. Therefore, 37.4°C does not necessarily mean that you have neocoronavirus pneumonia. Patients with neocoronavirus pneumonia may have no symptoms in the early stages, or they may present with a low-grade fever, dry cough, and malaise; or some patients may develop symptoms such as nasal congestion, runny nose, and sore throat. If you are suspected of having new coronavirus pneumonia, it is important to go to the hospital for nucleic acid testing or notify the staff to visit your home for testing in a timely manner in order to reduce the risk of transmission of the virus.
