There are certain criteria for diagnosing novel coronavirus pneumonia, and the diagnosis can be confirmed early on with sufficient clinical evidence. The diagnosis is usually made by a hospital fever clinic. A suspected case can be identified with an epidemiological history and associated clinical manifestations until the diagnosis is confirmed by nucleic acid testing, as required by the latest treatment protocol. If there are early symptoms, such as fever or respiratory reactions, as well as clinical findings of inflammatory exudate and hematological reactions in the lungs, the case should be treated as a suspected patient. If there is a history of exposure to the infected area, it is best to go directly to the relevant place for screening, both to protect yourself and to be responsible for your family and those around you.
