Scientists from King’s College London discovered that 8.8% of those who reported positive test results for “Covid-19” had a rash as part of their symptoms, compared to 5.4% of people who tested negative.For further investigation, the team created a separate online questionnaire, collecting photos and information from nearly 12,000 people suffering from a rash and suspected of having “Covid-19” or confirmed by it.
A study of the symptoms of “Covid-19” also found that this rash can be divided into three categories, including:
A rash of the type of hives (urticaria), which is the sudden appearance of raised bumps on the skin that appear and disappear very quickly over hours, and it is usually very itchy.It can involve any part of the body, and it often starts with intense itching in the palms or soles of the feet and can cause swelling of the lips and eyelids.
A rash caused by prickly heat or the type of chickenpox that turns into areas with small, itchy red bumps that can occur anywhere on the body, especially the elbows and knees as well as the back of the hands and feet.
This rash can last for days or weeks.
Fingers of the hands and feet affected by what has been called “Covid toes” (frostbite), which are reddish and purple bumps on the fingers or toes. They may be painful but do not usually itch.
This type of rash is most specific to “Covid-19”, and it is more common in young people with the disease, and it tends to appear later.
The British Association of Dermatologists said: “This is a common pattern of viral infections with a symmetrical rash consisting of many red spots or bumps on the body.”
It is usually accompanied by symptoms of a viral illness such as fever, cough, and malaise. Covid-19 patients can develop this pattern, but they may not have other symptoms.
Dr. Mario Valchi, senior lecturer at Kings College London, who led the research, said that “Covid-19” patients reported suffering from a rash for weeks, much longer than the more common symptoms of the disease.
Dr. Falchi added in the study, which has not yet been published in a journal or reviewed by other scientists, “The rash of Covid-19 may appear in many forms and at different stages of the disease.”
Valchi noted that the rash “although it is less common than fever, is more specific to Covid-19 and lasts longer.”
