Novel coronavirus pneumonia may present with fever, gastrointestinal and respiratory symptoms. Clinical manifestations of novel coronavirus pneumonia may include fever and/or respiratory symptoms such as fever, dry cough, fatigue, and sore throat, as well as gastrointestinal symptoms such as loss of smell (taste) and diarrhea. However, these symptoms are not specific and should not be used as the main basis for diagnosis of novel coronavirus pneumonia. The diagnosis of novel coronavirus pneumonia needs to be verified with epidemiologic history and lung imaging and nucleic acid testing. Novel coronavirus pneumonia is suspected when fever and/or respiratory symptoms are present along with a history of travel or residence in the case-reporting community within 14 days prior to onset of illness. If the patient’s serology or nucleic acid test is positive for the new coronavirus nucleic acid test, or if the new coronavirus-specific IgM and IgG antibodies are positive without the new coronavirus vaccine, the patient can be identified as a confirmed case. [Note: In this article, the terms “neocoronavirus pneumonia and novel coronavirus pneumonia” were renamed to “novel coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
