Headache is an important clinical complaint. In several infectious diseases, headache might be a common clinical presentation. COVID-19 is the new emerging viral infection where patients commonly present with fever and dry cough. However, headache could be a clinical complaint in a subset of patients.
The available medical literature on clinical presentation of 46 patients, showed that headache was observed in three cases (rate = 6.52, 95% confidence interval = 2.18%–19.48%). In our setting in Thailand, where the disease has already emerged, of 42 cases of COVID in Thailand, three have headache (rate = 7.14, 95% confidence interval = 2.40%–21.25%). Regarding the nature of headache, it is usually bilateral generalized pounding headache. However, there are no available data on the duration and frequency of headache. No major precipitating or relieving factor is described in these patients. There is no effect of noise or light or no significant alteration of vision or sleep. Since there is no significant neurological deficit, there is no need for additional neuroimaging in such patients.
The rate in Thai patients is similar to that in Chinese patients. Based on this information, headache might be a possible but not common clinical presentation in COVID-19 infection.
