Patients with novel coronavirus infection may have a sore throat, but not all patients with a sore throat have a novel coronavirus infection. Because the more common causes of sore throat are bacterial or viral infections, and viral infections are divided into herpes virus, adenovirus and rhinovirus, etc., different treatment plans are chosen according to the type of virus. If you have a sore throat, you should first apply antiviral medication to treat it, and improve blood tests and nucleic acid tests if necessary to determine whether it is a coronavirus.
