Skin Diseases Associated With COVID-19: A Narrative Review

COVID-19 is an infectious disease caused by SARS-CoV-2, which emerged in China in 2019 and rapidly spread worldwide to become a pandemic in March 2020. Although the most severe manifestations concern the lower respiratory tract, COVID-19 is a multiorgan disease that also affects the skin. Several types of skin lesions have been reported to be associated with SARS-CoV-2 infection, though their causal relationship with the virus has not yet been well documented. In addition to the cutaneous manifestations that develop in patients with COVID-19-thought to be caused by the virus-other findings associated with the pandemic in a broader sense include dermatoses triggered or aggravated by the infection, the adverse cutaneous effects due to the drugs and protective devices used to prevent or fight the infection, and the adverse cutaneous effects of COVID-19 vaccines. We provide an overview of these dermatoses associated with the COVID-19 pandemic.
