Rashes had been reported, China and Europe in hospitalised patients
Study to systematically gather data about skin rashes in milder cases in the wider population
Viral skin rashes, (Dr Veronique Bataille)
“Many viral infections can affect the skin, so it’s not surprising that we are seeing these rashes in COVID-19,”
“However, it is important that people know that in some cases, a rash may be the first or only symptom of the disease
So if you notice a new rash, you should take it seriously by self-isolating and getting tested as soon as possible.”
Study initial findings
336,000 regular UK app users
8.8% of people reporting a positive coronavirus swab test had experienced a skin rash as part of their symptoms
Also, rash reported in a further 8.2% of users with cough, fever or anosmia
5.4% of people with a negative test result
To investigate further
Images and information from 12,000 people
17% of respondents testing positive for coronavirus reported a rash as the first symptom of the disease
21% of those confirmed as being infected with coronavirus, the rash was their only symptom
Rashes, three categories
Hive-type rash (urticaria)
Raised bumps on the skin which come and go quite quickly (hours) and are usually very itchy
Can involve any part of the body
Often starts with intense itching of the palms or soles
Can cause swelling of the lips and eyelids
These rashes can present quite early on in the infection, but can also last a long time afterwards
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
Particularly the elbows and knees, back of the hands and feet
The rash can persist for days or weeks.
COVID fingers and toes (chillblains)
Reddish and purplish bumps on the fingers or toes
May be sore but not usually itchy
This type of rash is most specific to COVID-19
More common in younger people
Tends to present later on
Dr Justine Kluk
“These findings highlight the importance of keeping an eye on any new changes in your skin, such as lumps, bumps or rashes.
Early reporting of COVID-associated rashes by members of the public and recognition of their significance by frontline healthcare practitioners
May increase the detection of coronavirus infections and help to stop the spread.”
Dr Tanya Bleiker, President, British Association of Dermatologists
“Documenting the skin symptoms associated with COVID-19 is an important piece of the puzzle in building our understanding of the disease.
Skin symptoms may play a crucial role in detecting infection in people who are otherwise asymptomatic."
We’re delighted to be working with the team at KCL to make an image library of COVID-19 skin manifestations accessible on a dedicated website.
This will help healthcare professionals guide their decision making in clinical settings
and may have a role in educating the public about skin symptoms which would warrant self-isolation.”
