Is cough and sore throat a symptom of new crown infection?

Cough and sore throat are symptoms of COVID-19 infection, but they are not common clinical manifestations of COVID-19 infection. The most common clinical manifestations of COVID-19 infection are fever and symptoms of lower respiratory tract infection, but cough and sore throat are symptoms of upper respiratory tract infection, not symptoms of lower respiratory tract infection, so cough and sore throat are not common clinical manifestations of COVID-19 infection. For patients with cough and sore throat, upper respiratory tract infection will be considered first. If the patient has no history of exposure to COVID-19 infection, the possibility of COVID-19 infection is unlikely. However, for patients with a history of COVID-19 exposure, even if they only present with cough and sore throat, the possibility of COVID-19 infection cannot be ruled out. For some mild COVID-19 infections, symptoms of upper respiratory tract infection can be presented.
