Some patients with novel coronavirus infection have sore throat, but it is not the main symptom of novel coronavirus pneumonia. As an infectious disease, novel coronavirus infection is a warm disease, there should be evidence of heat, fever itself is evidence of heat, so do not rule out the presence of respiratory mucosal heat manifestations, such as sore throat or chest pain, but it is not the main manifestation, because the disease develops relatively quickly, the virus infection directly into the lungs, the tendency is particularly strong, directly into the respiratory tract. So the surface heat evidence in the early stage is not as much as other common colds, the incidence of sore throat is not very high, and can not be used as the main diagnostic basis. Once the patient has fever and dyspnea, it is a sign of critical illness and an important indication for observation. Source: Dr. Yurai
