Worms don’t cause ringworm.  Instead, this skin infection is caused by a fungus living off dead skin, hair, and nail tissue.

 

Starting as a red, scaly patch or bump, it develops into itchy red ring(s) with raised, blistery, or scaly borders.

 

Ringworm is passed on by skin-to-skin contact with a person or animal, and by sharing items like towels or sports gear.

 

Most ringworm infections can be treated with antifungal creams that can be bought over the counter such as Daktarin.
