Fever is the prominent manifestation of novel coronavirus pneumonia, but during the incubation period there can be no symptoms or no fever, but past the incubation period, the patient can have a fever. Some people may have a fever of 37.3°C, some may have a fever of 37.5°C, and some may have a fever of more than 38°C. However, once diagnosed with novel coronavirus pneumonia, they have to be isolated. This is because the disease is characterized by contagiousness. The most important way to treat infectious diseases is to identify and isolate the source of infection. Therefore, once it is clear that this is a novel coronavirus pneumonia, isolation is necessary. At the same time, the patient may have recurrent fever, because this disease may be induced in the process of infection, the patient has chronic underlying diseases, such as chronic bronchitis, chronic obstructive pulmonary disease, after this coronavirus infection, may be induced on the basis of viral infection and bacterial infection, which will make the disease very complex, the condition of the disease will fluctuate greatly. There is a possibility that after the fever is under control, the infection will come back and the fever will come back again. Viral infection itself is characterized by the process of self-healing, from the incubation period and then to the onset of the disease to the recovery period, so from the perspective of fever, the monitoring of fever is from the fever lasted for a few days to the improvement of the disease, cure, normal temperature, which is also the pattern of change in the development of the disease itself.
