Novel coronavirus infection may cause dry and itchy throat, but this symptom is not caused only by novel coronavirus infection, other bacterial and viral infections can also cause it. Novel coronavirus infection is often characterized by fever, dry cough, malaise, nasal congestion, runny nose and other symptoms, and in severe cases, progressive dyspnea. However, the above symptoms lack specificity and are not diagnostic. For people with obvious exposure history, if they only have dry and itchy throat, treatment at fever clinic is not recommended and they can isolate themselves at home. However, if symptoms gradually worsen and the above-mentioned manifestations appear, it is necessary to promptly go to the fever clinics in each region for pathogenic testing and to receive isolation treatment at designated hospitals after the diagnosis is confirmed.
