The main manifestations of novel coronavirus are fever, malaise, sometimes sore throat, nasal congestion, gastrointestinal symptoms such as nausea, vomiting, diarrhea, and in severe cases, respiratory distress, respiratory failure, and even coma. If the patient has a history of epidemiological exposure and the above clinical manifestations occur, the possibility of novel coronavirus infection should be considered and the patient should actively seek medical attention to improve the relevant tests, including routine blood tests, calcitoninogen and nucleic acid. If the patient is diagnosed with novel coronavirus infection, he/she should be treated in isolation at a designated hospital and it is crucial to seek active medical attention.
