Headache is not a common symptom of novel coronavirus pneumonia, and only a very small number of patients or those with more severe symptoms have headache. If there is no epidemiologic history and there is only headache without fever, it is not considered novel coronavirus pneumonia. If there is an epidemiologic history of headache but there is no fever, it is important to go to the hospital for further examination. For close contacts, that is, those who have had contact with a confirmed infected person within 2 meters, the presence of any symptoms in a close contact cannot be easily ruled out. On the contrary, there are some infected people who do have no symptoms but are also contagious. If isolation is not done properly, the virus may be transmitted to other people. Although there are no symptoms, there are more examples of others who may have symptoms or even critical symptoms after infecting others. Therefore, the diagnosis or exclusion of novel coronavirus pneumonia should not be based on a single symptom, but rather on the epidemiologic history. For symptoms that occur during isolation, it is important to go to the hospital and ask the doctor to do relevant tests to evaluate. For those who have no epidemiological history and have only headache symptoms, they need to continue observation and comprehensive judgment of the cause, or go to a specialist, such as a neurologist, to diagnose the cause of the headache if necessary.
