The current method of temperature measurement is based on axillary temperature measurement with a thermometer. If the axillary temperature exceeds 37.3℃, it is considered to have fever, and 37.3℃-38℃ is considered to be hypothermia. There are many diseases that can present with hypothermia, so we cannot judge whether the patient is suffering from novel coronavirus pneumonia simply based on the elevated body temperature, i.e., a simple body temperature of 37.5℃ cannot be diagnosed as novel coronavirus pneumonia. At present, the diagnosis of novel coronavirus pneumonia is based on the following three criteria: 1) the patient has fever, cough, sputum, chest pain, dyspnea, and severe coughing up of blood, which are the clinical manifestations of the patient; 2) the patient has typical viral infections on chest X-ray or chest CT or imaging features; 3) the patient has respiratory secretions such as sputum, snot, or pharyngeal mucus, which are detected in the secretions of novel coronavirus pneumonia; 4) the patient has a low-grade fever. The patient’s respiratory secretions, such as sputum, nasal mucus or pharyngeal mucus, from which novel coronavirus nucleic acids are detected. The diagnosis of a patient with novel coronavirus infection can only be made if all three of the above criteria are met, and the diagnosis cannot be made by a body temperature of 37.5°C alone.
