Among one of the odder reported symptoms of Covid-19 has been the mysterious “COVID toes.” People have been reporting that their toes are red, sore, itchy and discolored, often with no or limited other symptoms that would indicate they were sick with Covid-19. For many, the condition feels and looks like chilblains, which can be experienced when toes and feet get too cold, but shortly after the pandemic started, reports and even tweets from people experiencing these symptoms started to roll in from all over the world, including in warm places where this was unlikely to be the cause.

Dermatologists have been puzzling over this for months, collecting more information and cases and now they might have just found out why the SARS-CoV2 seems to cause these rather unusual symptoms.
