, or ringworm, is a skin infection caused by a fungus. It usually affects the skin on your face, chest, or limbs. Tinea corporis is most common in children and athletes.
Common signs and symptoms include the following:
Tinea corporis may begin as 1 or more flat, red patches. As the infection grows, it spreads out in a circle or ring, leaving normal-looking skin in the middle. At the edge of the ring, the skin is red and raised. It may be either dry and scaly, or moist and crusty. The infected skin may itch. Although the infection looks like you have a worm under your skin, there is no worm.
Contact your healthcare provider if:
- You have a fever.
- Your rash continues to spread after 7 days of treatment.
- Your rash is not gone in 2 weeks.
- The area around your rash becomes red, warm, tender, swollen, or smells bad.
- You have questions or concerns about your condition or care.
Tinea corporis is usually treated with antifungal medicine. It may be given as a cream or pill. Take the medicine until it is gone, even if it looks like your infection is gone sooner.
Prevent the spread of tinea corporis:
- Wash all items that come into contact with infected skin. Wash all towels, clothes, and bedding in hot water. Use laundry soap. Clean shower stalls, mats, and floors with a germ-killing or fungus-killing cleaner.
- Do not share personal items. Do not share towels, brushes, combs, or hair accessories.
- Keep your skin, hair, and nails clean and dry. Bathe every day, and dry your skin before you put medicine on the infected area. Wash your hands often. Do not scratch your sores. This may cause the infection to spread.
- Do not participate in contact sports , such as wrestling, for 72 hours after starting treatment. Talk to your healthcare provider before you participate in contact sports.
- Have infected pets treated by a veterinarian. A patch of missing fur is a sign of infection in a pet. Wear gloves and long sleeves if you handle an infected animal. Always wash your hands after handling the animal. Vacuum your home to remove infected fur or skin flakes. Disinfect surfaces and bedding that your animal comes into contact with.
