People don't get it. The inflammatory process can do these sort of thing to any organ or system, or parts of them.

People got a thing called COVID Toe. This is where you and every person already has some fungus that live on their feet and which gets into the skin and toenails. Maybe you have a little yellowing of the toenails or you're just "prone to athletes foot."

Then you get COVID and suddenly your immune system is working overtime. The fungus starts to multiply faster and spreads more aggressively. Your toes start to get itchy and red, more than usual. They swell. They yellow. Then they start to crack and ooze, possibly requiring surgical debridement or in the most severe cases, such as where the patient already had diabetes affecting their peripheral nerves, amputation of the foot to prevent necrosis and sepsis.
