If you suspect you have a novel coronavirus infection, you can make a preliminary determination based on your epidemiologic history and clinical symptoms. If you have been to a moderate-to-high risk area within 14 days and are currently experiencing respiratory symptoms such as fever, malaise, and dry cough, you should consider the possibility of novel coronavirus infection. The diagnosis should be made at the fever clinic as soon as possible, with blood tests, chest CT, and coronavirus nucleic acid testing. The tests will confirm whether the patient is infected with the novel coronavirus, and once confirmed, the patient should be isolated immediately, and close contacts of the patient should be isolated and examined.
