Ringworm--despite its misleading name--is actually caused by a fungal infection. It's not a worm. It is a superficial skin infection, and it's unlikely to cause serious harm unless left untreated. It can affect the skin on the body, scalp, groin (jock itch), or feet (athlete's foot). It is spread through contact and can affect both domesticated animals and humans.
Red, Raised, Scaly Patches
Ringworm often shows as a circular shaped ring of red rash. The skin on the inside of the rash is normally clear. This tell-tale "ring" gives ringworm its name.
Rash, Itching
Not all ringworm infections take the ring shape. They can also look like a regular rash, or there may be an area that itches. Ringworm does not always itch.
