COVID-19-induced headache in Boston and the vicinity.

Headache is a common neurological symptom of Coronavirus disease 2019 (COVID-19) patients. However, the prevalence, comorbidities, and ethnic susceptibilities of COVID-19-induced headaches are not well-defined. We performed a retrospective chart review of patients who tested positive for SARS-CoV2 by reverse transcriptase-polymerase chain reaction (RT-PCR) in March and April 2020 at Massachusetts General Hospital, Boston, Massachusetts, USA. In the study, we identified 450 patients, 202 (44.9%) male, and 248 (55.1%) female, who tested positive for COVID-19. Headache is a significant painful symptom affecting 26% of patients. Female predominance is determined in sore throat, nasal congestion, hypogeusia, headache, and ear pain. In contrast, pneumonia and inpatient hospitalization were more prevalent in males. Younger patients (< 50) were more likely to develop sore throat, fatigue, anosmia, hypogeusia, ear pain, myalgia /arthralgia, and headache. In contrast, older (> 50) patients were prone to develop pneumonia and required hospitalization. Ethnic subgroup analysis suggests Hispanic patients were prone to headaches, nausea/vomiting, nasal congestion, fever, fatigue, anosmia, and myalgia/arthralgia compared to non-Hispanics. Headache risk factors include nausea/vomiting, sore throat, nasal congestion, fever, cough, fatigue, anosmia, hypogeusia, dizziness, ear pain, eye pain, and myalgia/arthralgia. Our study demonstrates regional gender, age, and ethnic variabilities in COVID symptomatology in Boston and the vicinity. It identifies mild viral, painful, and neurological symptoms are positive predictors of headache development in COVID-19.
