There are many causes of a sore throat, which need to be clearly diagnosed and treated. The diagnosis of novel coronavirus pneumonia due to novel coronavirus is based on epidemiology (in medium or high-risk areas and belonging to dense or sub-dense populations), symptoms (fever, cough, sore throat, diarrhea, conjunctivitis, etc.), positive nucleic acid tests, and a CT scan of the chest, and cannot be confirmed on the basis of the symptom of a sore throat alone. In addition to the new coronavirus pneumonia, sore throat can be caused by acute tonsillitis, acute pharyngolaryngitis, common cold, gastroesophageal reflux, tumors and other diseases, and will be accompanied by the clinical symptoms and manifestations of the corresponding diseases. The symptoms of sore throat, need to go to the hospital for relevant examinations to clarify the diagnosis, can not be randomly used medication.
