A fever of 37.5°C cough is not necessarily due to novel coronavirus pneumonia. There are more causes that can cause a fever of 37.5°C cough, such as cold, bronchitis, and common pneumonia. In particular, colds need to be differentiated from novel coronavirus pneumonia. In addition, patients with novel coronavirus pneumonia do not always present with fever of 37.5°C. Patients with mild symptoms may have no significant fever. Severely and critically ill patients may have a low fever (37.5°C-38°C) to moderate fever (38.1-39°C) or even no significant fever during the course of the disease. Some patients may present with only a low fever. A small number of infected patients even have no obvious clinical symptoms.
