Case report: SARS-CoV-2-induced urticaria or just a concomitance?

Abstract

The association between urticaria and different virus infections has been reported in many studies. Different virus infections have been reported to be comorbidities of spontaneous urticaria. In this paper, we report the case of a male patient with acute urticaria 7 days after he left the hospital where he was treated for coronavirus disease 2019 (COVID-19). This infection may act as a causative or a facilitating factor for the initiation of acute urticaria and additional cofactors such as stress may contribute for the urticaria phenotype to be expressed. Additional facts for severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus in future will clarify if urticarial rash is one of the COVID's multiple faces.
