In this issue of JAMA Dermatology, clinical cases and images of rashes in patients infected with severe acute respiratory syndrome coronavirus (SARS-CoV-2) are presented. Although these early observations are not comprehensive of all skin manifestations seen, our intention in publishing them is to help dermatologists recognize emerging patterns of rashes in patients with coronavirus disease 2019 (COVID-19). The reported prevalence of cutaneous signs in association with this pandemic is conflicting; one study reported a rash in only 0.2% of a cohort of Chinese patients, whereas the estimated prevalence in a cross-sectional Italian study was 20.4%. In the latter study, performed by dermatologists, the cutaneous manifestations were most commonly described as an erythematous rash; however, a range of additional morphologic features was observed, including generalized urticaria and vesicular eruptions. A predilection for the trunk was also noted. It may not be possible to determine the exact prevalence of skin findings in infected patients until serologic testing is more widely available, given that some individuals may lack the typical respiratory signs of COVID-19.
