While dry cough, fever, and shortness of breath are the classic symptoms of COVID-19 infections, some people also experienced redness and swelling of the hands and toes known as chilblain-like lesions.
A new study published in the British Journal of Dermatology explores the underlying mechanisms involved in such conditions, also known as “COVID toes”.
In the study, researchers at the University of Paris conducted blood and skin tests and found that two parts of the immune system, which involve mechanisms to fight COVID-19 might be the reason, BBC reported.
One is an anti-viral protein called Type-1 interferon and the other is a type of antibody that mistakenly attacks the person’s own cells and tissues, not just the invading virus.
