Some patients with novel coronavirus can present with nasal congestion and sore throat, but nasal congestion and sore throat are not necessarily due to novel coronavirus infection. Many infectious diseases of the respiratory tract can cause nasal congestion and sore throat, such as colds. In addition, pharyngitis, laryngitis, and bronchitis can all have corresponding symptoms. The symptoms are similar to those of neocoronavirus infection, but patients with neocoronavirus infection tend to have fever, cough, and also have difficulty breathing. Other patients may have digestive symptoms, such as weakness, poor appetite, nausea, vomiting, abdominal pain, diarrhea, etc., which are not the same as the common cold or sore throat, so care should be taken to differentiate them.
