The common symptoms of novel coronavirus infection include fever, dry cough, malaise, and some patients have flu-like symptoms such as nasal congestion, runny nose, sore throat, headache, and general aches and pains. The symptoms alone cannot determine whether there is novel coronavirus infection. If novel coronavirus infection is suspected, it is usually important to look at the epidemiological history within the last 14 days, for example, whether there has been close contact with patients with confirmed novel coronavirus pneumonia within the last 14 days, such as eating together, studying in a classroom or working in an office. If this is the case, further testing for novel coronavirus nucleic acid should be performed, usually by taking a nasopharyngeal swab, or sputum, blood, urine, or stool to test for novel coronavirus nucleic acid, and if the test is positive, then there is a possibility of novel coronavirus infection.
