The skin condition known as Covid toe may be a side-effect of the immune system's response to fighting off the virus, according to a study.

The symptom results in chilblain-like inflammation and redness on the hands and feet, with the condition sometimes lasting for months at a time. It typically develops within a week to four weeks of being infected and can result in toes and fingers becoming swollen or changing colour.
