A new study provides insights about a symptom called COVID toes that causes redness and swelling of the hands and toes during the COVID-19 pandemic.

The mechanisms behind both types involved an immune response with high levels of certain autoantibodies as well as type I interferon, a key protein in the antiviral response.
In addition to the immune system, endothelial cells that line blood vessels also appeared to play a critical role in the development of COVID toes and chilblains.
The epidemiology and clinical features of chilblain-like lesions have been extensively studied and published. However, little is known about the pathophysiology involved. Future studies involving a large population can provide more insight.
