MOSCOW, November 1 - RIA Novosti. Doctors have published photos of an atypical manifestation of coronavirus: red and purple bumps on the fingers and toes of patients. Reported by the Huffington Post.
Before the pandemic, such bumps on the legs and arms were considered the result of frostbite. However, with the increase in the number of people infected with coronavirus infection, more and more people began to complain of this symptom even in the warm season, which alarmed doctors.
Researchers have found 12,000 people infected with COVID-19 with bumps on their fingers and toes. The doctors asked them to provide photographs of the skin manifestations of the infection.
Patients interviewed noted that red and purple bumps may hurt, but usually do not itch. When the rash heals, the top layers of the skin can peel off.
Doctors clarified that the connection between such inflammation of the skin and the coronavirus was revealed thanks to skin biopsies of children with "covid fingers". Despite the negative COVID test they passed, the virus was found in endothelial cells, as well as in sweat glands.
"Endothelial damage may be a key mechanism causing such lesions," notes one of the experts Nino Jesus.
The International League of Dermatological Societies and the American Academy of Dermatology have found that "covid fingers" can persist in patients for 15 days, but sometimes they appear up to 130-150 days.
The researchers added that such a symptom could be key for detecting the virus, especially in those who carry COVID-19 without other symptoms.
