COVID-19 dermatology registry

Thank you for agreeing to take part in this important effort on behalf of the American Academy of Dermatology and the International League of Dermatologic Societies. Our hope is that information you and others provide will help us understand dermatologic manifestations of the COVID-19 virus, as well as skin reactions to the COVID-19 vaccine. This survey is for all health care professionals taking care of either (a) COVID-19 patients who develop dermatologic manifestations, including patients with “long COVID,” (b) dermatology patients with an existing condition who then develop COVID-19, or (c) patients who have received the COVID-19 vaccine and developed a skin reaction that you wish to report.

The case report form should take about 5-7 minutes to complete. Patient identifiers such as name or date of birth will not be collected. All de-identified information will be kept strictly confidential and will only be shared with researchers compiling information. Data will be stored on a secure Redcap server at Massachusetts General Hospital (Partners Healthcare). Information and updates will be shared via the COVID-19 American Academy of Dermatology website.

The success of this collaborative effort depends on active participation by our international health care community to obtain accurate and reliable information. This registry is for health care professionals from all countries. We ask that you share this site with your colleagues and encourage them to report any cases of COVID-19 related dermatoses.


Please only enter a case if you are a physician or health care professional. Patients should not enter their own cases.

If you are a patient who would like your case included, share the link www.aad.org/covidregistry with the person providing your care. Want to learn more about COVID-19 and skin? Visit our public coronavirus resource center.
