Headache and fever are not necessarily symptoms of novel coronavirus pneumonia, but patients with novel coronavirus can present with headache and fever. Many diseases can present with headache and fever, such as influenza, common cold, other pneumonia such as bacterial pneumonia, mycoplasma, chlamydia or non-novel coronavirus infected pneumonia, can present with headache and fever. Therefore, headache and fever should not be taken as diagnostic evidence when diagnosing patients with novel coronavirus infections. Evidence of headache and fever should be highly suspicious of the possibility of infection, but should not be used as a confirmatory criterion. To confirm the diagnosis, the patient must have symptoms of cough and sputum, clear imaging features of viral infection on chest imaging, and the ability to isolate novel coronavirus nucleic acid from the patient’s respiratory secretions. The diagnosis of novel coronavirus pneumonia can be made only after the three conditions are met. Headache and fever alone cannot be used as a basis for the diagnosis of novel coronavirus pneumonia.
