A sore throat is not necessarily a new coronavirus pneumonia, because a variety of upper respiratory tract diseases can cause a sore throat, such as acute tonsillitis, parapharyngeal abscess, peri-tonsillitis, etc. It is not possible to determine whether a single manifestation of a sore throat is a new coronavirus. The typical symptoms of novel coronavirus infection are fever, malaise and dry cough at the beginning of the disease, and respiratory symptoms such as difficulty in breathing gradually appear as the disease progresses, and a few patients have nasal congestion, runny nose, sore throat and diarrhea. To confirm the diagnosis of novel coronavirus infection, in addition to the history of close contact with the infected person or suspected infected person and related clinical symptoms, the diagnosis must be confirmed by combining relevant laboratory and chest imaging examinations, novel coronavirus nucleic acid testing, viral gene sequencing and other indicators, so the diagnosis of novel coronavirus cannot be made simply based on a sore throat.
