Patients with new coronavirus pneumonia will have a high temperature, and fever is the first symptom of new coronavirus pneumonia. However, there are some patients who do not have a high temperature and simply have a cough, which can be diagnosed by CT and nucleic acid testing of both lungs. Most patients with novel coronavirus pneumonia have a low-grade fever, with an approximate temperature of 37.3-38°C. A small number of patients with severe coronavirus pneumonia have a low temperature. There are a few severe cases with persistent high fever, chest tightness, shortness of breath and respiratory distress syndrome, and in severe cases, acute respiratory failure and systemic sepsis, which can lead to death in a short time. Therefore, in general, the body temperature of patients with neoconiosis is not fixed, and the diagnosis of neoconiosis cannot be made solely on the basis of body temperature.
