Fever and fever remission is a characteristic manifestation of novel coronavirus pneumonia, but not all patients with fever remission are suffering from novel coronavirus pneumonia. There are many other diseases, such as acute rhinovirus, adenovirus, herpes zoster virus, and other infections, that also present with fever and fever remission. In addition to fever, other symptoms such as malaise, dry cough, chest tightness, etc. may also be present after a person has been infected with a new coronavirus. Once the body temperature exceeds 37.3°C or higher, you need to visit a fever clinic in a hospital for investigation. If you are in an infected area or have been in contact with someone from an infected area, you need to pay high attention to the symptoms of the flu, and you need to urgently rule out any infection of the new crown pneumonia. At the same time, it is necessary to do a good job of protection in daily life, especially for people with occupational exposure.
