Headache May Predict Clinical Evolution of COVID-19
-
Headache may be a key symptom of COVID-19 that predicts the disease's clinical evolution in individual patients, new research suggests. An observational study of more than 100 patients showed that headache onset could occur during the presymptomatic or symptomatic phase of COVID-19 and could resemble tension-type or migraine headache. Headache itself was associated with a shorter symptomatic period, while headache and anosmia (loss of sense of smell) were associated with a shorter hospitalization period. In a subgroup of participants, headache persisted even after the symptoms of COVID-19 had been resolved.

@milind Headache is one of the main symptoms of COVID-19. A recent study of 214 patients with COVID-19 showed that approximately 13% of the participants had headache and 5% had anosmia. SARS-CoV-2 penetrates the cells through the ACE2 receptor, which is present throughout the body.
