Several pathological studies conducted on COVID-19 patients show that headache is one of the most common symptoms of the infection.
According to PubMed Central (PMC), a systematic review and meta-analysis estimated that 80 percent of the patients infected with SARS-CoV-2 developed one or more long-term symptoms. The five most common symptoms were fatigue (58 percent), headache (44 percent), attention disorder (27 percent), hair loss (25 percent), and dyspnea (24 percent).
The Journal of Headache and Pain also conducted a study on the COVID-19 related headache. A binary logistic regression model was performed to differentiate the characteristics of headaches related to COVID-19. The study included 3,458 participants with a mean age of above 40 years, of that 262 participants had COVID-19 related headaches associated with anosmia/ageusia and gastrointestinal complaints.
Also, some studies and reviews highlighted headache as the most common neurological symptom that, often accompanied by high fever.
Moreover, a study published in the Journal of Neurology, Neurosurgery, and Psychiatry also found that headache is a common symptom in COVID-19 patients. A team led by University College London researchers conducted a systematic review and meta-analysis of 215 COVID-19 studies from 30 countries involving 105,638 symptomatic COVID-19 patients from January to July 2020 and found that headache was more prevalent in many patients, even among those with milder COVID-19 infection.
Therefore, headache is considered a common symptom of COVID-19.
