However, this is the first and largest study to systematically gather data about skin rashes in milder cases in the wider population. This type of rash is most specific to COVID-19, is more common in younger people with the disease, and tends to present later on.Īlthough COVID-19 is often thought of as a disease that affects the respiratory system, rashes had been reported in a number of cases of people in China and Europe who had been hospitalised with severe symptoms of the disease. COVID fingers and toes (chilblains): Reddish and purplish bumps on the fingers or toes, which may be sore but not usually itchy. ![]() ‘Prickly heat’ or chickenpox-type rash (erythemato-papular or erythemato-vesicular rash): Areas of small, itchy red bumps that can occur anywhere on the body, but particularly the elbows and knees as well as the back of the hands and feet.These rashes can present quite early on in the infection, but can also last a long time afterwards. It can involve any part of the body, and often starts with intense itching of the palms or soles, and can cause swelling of the lips and eyelids. Hive-type rash (urticaria): Sudden appearance of raised bumps on the skin which come and go quite quickly over hours and are usually very itchy.The rashes associated with COVID-19 fall into three categories: And for one in five people (21%) who reported a rash and were confirmed as being infected with coronavirus, the rash was their only symptom. ![]() The team particularly sought images from people of colour, who are currently under-represented in dermatology resources. Thank you to all who submitted photographs of their rashes.ġ7% of respondents testing positive for coronavirus reported a rash as the first symptom of the disease. To investigate further, the team set up a separate online survey, gathering images and information from nearly 12,000 people with skin rashes and suspected or confirmed COVID-19. ![]() Similar results were seen in a further 8.2% of users with a rash who did not have a coronavirus test, but still reported classic COVID-19 symptoms, such as cough, fever or anosmia (loss of smell). Researchers discovered that 8.8% of people reporting a positive coronavirus swab test had experienced a skin rash as part of their symptoms, compared with 5.4% of people with a negative test result. After noticing that a number of participants were reporting unusual skin rashes, the researchers focused on data from around 336,000 regular UK app users. The COVID Symptom Study, led by researchers from King’s College London and health science company ZOE, asks participants to log their health and any new potential symptoms of COVID-19 on a daily basis. Data from the COVID Symptom Study shows that characteristic skin rashes and ‘COVID fingers and toes’ should be considered as key diagnostic signs of the disease, and can occur in the absence of any other symptoms. ![]()
