37.4℃ is not necessarily new coronavirus pneumonia. A body temperature of 37.4℃ is usually clinically classified as hypothermia. There are many causes of hypothermia, such as respiratory infections, colds, pharyngitis, laryngitis, tonsillitis, bronchitis, and pneumonia, which can all cause 37.4℃ hypothermia. Non-infectious diseases can also cause 37.4°C hypothermia, such as connective tissue diseases, rheumatoid, rheumatism, and endocarditis, which can also cause 37.4°C hypothermia. Therefore, it does not mean that 37.4°C is new coronavirus pneumonia. In addition to a low-grade fever, patients with novel coronaviral pneumonia can also have a dry cough and fatigue, and some patients may even have symptoms of acute upper respiratory tract infection such as sore throat, nasal congestion, and runny nose. Therefore, novel coronaviral pneumonia is often not judged by clinical symptoms, but requires nucleic acid testing to clarify.
