The presence of a sore throat does not prove that a person is infected with a novel coronavirus, but it cannot be completely ruled out either. The epidemiological data on novel coronaviruses are not yet complete. According to a study of current cases, the main symptoms of novel coronavirus infection in humans are mainly fever, accompanied by dry cough, general malaise and progressive dyspnea. Some infected individuals with atypical symptoms may first present with other systemic manifestations, such as nasal congestion, runny nose, headache, sore throat, diarrhea, heartburn, chest tightness, and conjunctivitis. For people with a history of exposure and symptoms of sore throat, the first step should be self-isolation at home. If the symptoms gradually decrease, it means that there is no viral infection; if the symptoms gradually worsen in the next few days and manifestations such as fever and respiratory distress appear, you should promptly go to each regional fever clinic for pathogenetic testing to confirm the diagnosis.
