Urticaria is one of the most common skin manifestations reported in patients with coronavirus disease 2019 (COVID-19), with more than half of urticarial rashes occurring before or during classic symptoms of COVID-19, according to research data published in Dermatologic Therapy.
Based on findings from this review, the presence of urticarial rashes coupled with “fever should require clinicians to strongly consider COVID-19 testing during the pandemic, as this may the only presenting symptom in some patients,” according to the researchers.
