While the usual symptoms of COVID-19 infections include a dry cough, fever, and shortness of breath, some persons also suffered chilblain-like lesions, which include redness and swelling of the hands and toes.
The fundamental mechanisms involved in such diseases, commonly known as “COVID toes,” are investigated in a new study published in the British Journal of Dermatology.
According to the BBC, researchers at the University of Paris used blood and skin testing to discover that two elements of the immune system, which include mechanisms to combat COVID-19, could be the cause.
The first is an antiviral protein called Type-1 interferon, and the second is an antibody that fights the person’s own cells and tissues rather than the invading virus.
According to experts from the University of Paris, France, cells lining small blood arteries supplying the damaged areas are also involved.
In the spring of 2020, the researchers evaluated 50 persons with probable COVID toes, as well as 13 others with comparable chilblains lesions that were not linked to COVID infections since they happened before the pandemic began, according to the article.
“The lesions, like conventional chilblains observed during cold spells and in patients with circulatory difficulties, usually go away on their own for the most part. Some people, however, may require therapy with lotions and other medications “UK podiatrist Ivan Bristow was cited as stating.
“The validation of the reason will aid in the development of new medications to better manage it,” he added.
COVID toe, which appears to be a side effect of the body’s move to attack mode to combat the virus, can afflict anyone of any age, but it is more frequent in children and teenagers.
It may be mild for some, but for others, the rash can be exceedingly painful and itchy, with acute blisters and swelling. Some, on the other hand, develop painful raised bumps or rough skin regions with pus. People who have the disease typically don’t show any of the classic COVID symptoms, which might last for months or weeks.
The COVID toe condition was common in the early stages of the pandemic, but it is now less common. According to Veronique Bataille, a consultant dermatologist and spokeswoman for the British Skin Foundation, this could be due to more people being vaccinated or having some protection against COVID-19 from previous infections.
