Recurrent fever is not necessarily a novel coronavirus. Recurrent fever is a typical symptom of viral infections, which can be classified as other viral infections such as herpes virus, influenza virus and common viral infections. In case of recurrent fever, other clinical symptoms such as dry cough and chest tightness and chest pain need to be observed at the same time. In severe cases, the patient may experience a dramatic worsening of the disease within a short period of time. If there is a change in the condition, it is necessary to go to the hospital in time to improve the relevant examination to clarify.
