A questionnaire survey was conducted to clarify the headache situation in people with chronic headache during the new coronavirus disease 2019 (COVID-19) infection. A questionnaire survey was conducted on the internet. The subjects were 600 women in their 20s to 40s who were infected with the 7th wave of COVID-19 infection from July to October 2022. Subjects (55.7%) had headaches at the time of infection, and most of the infected people were recuperating at home. Other headaches (excluding migraine) accounted for about 60% of existing headaches in both the headache group and the headache-free group, but people with migraine accounted for 30.5% of the headache group, and those without headache accounted for 23.3% of the headache-free group. In the headache group, 40.3% had headaches even at the time of vaccination against COVID-19. In both the migraine group and other headache groups, compared to regular headaches, headaches during COVID-19 infection had a greater impact on daily life. Migraine headaches may have worsened in migraine carriers, as accompanying symptoms of migraine were observed at the time of infection. It is therefore important to note that chronic headache patients may develop severe headaches during COVID-19 infection.
