SARS-CoV-2 Infection and Vaccination Cutaneous Manifestations for the Inpatient Dermatologist.

Abstract

Purpose of ReviewThe overall purpose of this review was to characterize and summarize cutaneous eruptions associated with coronavirus disease 2019 (COVID-19) as well as COVID-19 vaccination.Recent FindingsCutaneous eruptions associated with COVID-19 infection have a reported frequency of 1–20%. Increased COVID-19 disease severity has been associated with morbilliform exanthems, urticaria, retiform purpura, and livedo racemosa. Papulovesicular eruptions were associated with a milder COVID-19 disease course. A range of dermatoses have also been reported with COVID-19 vaccination but have rarely prevented subsequent vaccination.SummaryDermatologists should be aware of the associations between COVID-19 disease severity and cutaneous eruptions. Livedo racemosa and retiform purpura are particularly associated with increased disease severity and death. In the setting of COVID-19 vaccination, cutaneous eruptions can largely be managed symptomatically and very rarely do these reactions prevent subsequent vaccination.
