From ‘COVID Toes’ to Hives, These Are the Skin Conditions Dermatologists Think Could Be Signs of Coronavirus

Dermatologists around the world are gathering data on what may be largely overlooked symptoms of COVID-19: skin conditions ranging from rashes to “pseudo-frostbite.”
Many viral illnesses—including chickenpox, measles and mononucleosis—are accompanied by telltale skin rashes, often a result of the body’s heightened inflammatory response while fighting off infection. Though more research is needed, a growing number of case reports and preliminary studies suggest SARS-CoV-2, the virus that causes COVID-19, can also affect the skin.
In late March, an Italian physician submitted a letter to the editor of the Journal of the European Academy of Dermatology and Venereology, describing skin conditions that affected about 20% of 88 COVID-19 patients analyzed in the Lombardy region of Italy. Most of them developed a red rash on their torsos, while a few suffered hives or blisters resembling chickenpox. Then, in early April, a dermatology organization representing more than 400 French dermatologists issued a statement noting that among probable COVID-19 patients they had seen skin symptoms including hives, red rashes and frostbite-like lesions on the extremities. And finally, in mid-April, in a letter to the editor of the Journal of the American Academy of Dermatology, a group of Italian physicians described a chickenpox-like rash as “a rare but specific COVID-19-associated skin manifestation.”
