Itchy throat is not necessarily a new coronavirus infection, in the clinical appearance of itchy throat is likely to be considered as a result of acute pharyngolaryngitis. Because of the new coronavirus pneumonia, most patients with fever as the first symptom, accompanied by fatigue, dry cough, some patients may have nasal congestion, runny nose, sore throat and other symptoms of upper respiratory tract infection. For new coronavirus pneumonia, the main thing is to confirm the diagnosis. The diagnosis can be confirmed by the following tests, such as routine blood test, C-reactive protein, myocardial enzyme profile, lung CT, if the routine blood test suggests that the total number of leukocytes is decreased, the total number of lymphocytes is decreased, myocardial enzyme is increased, and the CT of the lung has a glass-like change, then it is highly suspected to be a coronavirus infection. Viral nucleic acid testing can be further refined, and if the nucleic acid test is positive, the diagnosis of coronavirus infection can be confirmed. Once the diagnosis of novel coronavirus pneumonia is confirmed, the patient should be isolated and treated promptly.
