Ringworm causes a rash that's often ring-shaped. It may look red or darker than the surrounding skin, depending on your skin tone.
Ringworm is a fungal infection. It's not caused by a worm. It can be passed on by close contact with an infected person, animal, bedsheets and towels.
You can avoid spreading ringworm to others by getting treated as soon as possible, and by not sharing towels or bedding.
