Headache as a Cardinal Symptom of Coronavirus Disease 2019: A Cross‐Sectional Study	2020-09-28		.txt	text/plain	4335	256	46	OBJECTIVE: To describe the semiology of pain and its associated features in patients with coronavirus disease 2019 (COVID‐19) and headache presenting to the emergency department who do not require urgent services. 27 We hypothesized that COVID-19-related headache might be one of the most frequent symptoms of the infection and can have a more severe presentation in patients with migraine. We aimed to describe the semiology of pain and associated symptoms in patients with COVID-19-related headache in a clinical setting who visit the emergency department but do not require urgent services. Study Population and Eligibility.-Patients attending the emergency department of our hospital were included if they met all of the following inclusion criteria: (1) patients classified by the Manchester Triage System 29 as priority levels 5 (non-urgent) and 4 (standard); (2) fulfilled the criteria for a "probable COVID-19 case" or "confirmed COVID-19 case" according to the WHO guidance on global surveillance for COVID-19; 30 (3) and presented with headache alongside other COVID-19-related symptoms.	./cache/cord-321552-lsz1onrj.txt	./txt/cord-321552-lsz1onrj.txt
