A little sore throat is not necessarily a novel coronavirus infection, but may also be a pain caused by upper respiratory tract infection or acute pharyngitis, which can be treated symptomatically with medications to clear heat and detoxify the throat or apply antibiotics if necessary. If the sore throat improves significantly, it can also be disregarded as novel coronavirus infection. However, if the patient has been to an infected area within 14 days, or has been in contact with people infected with novel coronavirus, or has the characteristics of aggregated onset of novel coronavirus infection in the surrounding area, the sore throat should also be noted as a possible novel coronavirus infection, and a nucleic acid test can be done to confirm whether the patient is infected with novel coronavirus. People with epidemiological history must be isolated for observation, temperature measurement, and isolation and treatment for those who develop symptoms.
