Fungal infection of the body (tinea corporis) is a rash caused by a fungus. It's usually well defined red, itchy, circular lesion with clearance of skin in the middle.
Mild fungal infections responds to topical antifungal creams. For more-severe infections, you may need to visit your dermatologist.
Causes
Ringworm is a contagious fungal infection caused by parasites that live on the cells in the outer layer of your skin. It can be spread by:
- Human to human. Ringworm often spreads by direct, skin-to-skin contact with an infected person.
- Animal to human. You can contract ringworm by touching an animal with ringworm. Ringworm can spread while petting or grooming dogs or cats. It's also fairly common in cows.
- Object to human. It's possible for ringworm to spread by contact with objects or surfaces that an infected person or animal has recently touched or rubbed against, such as clothing, towels, bedding and linens, combs, and brushes.
- Soil to human. In rare cases, ringworm can be spread to humans by contact with infected soil. Infection would most likely occur only from prolonged contact with highly infected soil.
Management
You're at higher risk of ringworm of the body if you:
- Live in a warm climate
- Have close contact with an infected person or animal
- Share clothing, bedding or towels with someone who has a fungal infection
- Participate in sports that feature skin-to-skin contact, such as wrestling
- Wear tight or restrictive clothing
- Have a weak immune system
Complications
A fungal infection rarely spreads below the surface of the skin to cause serious illness. But people with weak immune systems, such as those with HIV/AIDS, may find it difficult to get rid of the infection.
Prevention
Ringworm is difficult to prevent. The fungus that causes it is common, and the condition is contagious even before symptoms appear. Take these steps to reduce your risk of ringworm:
Educate yourself and others. Be aware of the risk of ringworm from infected people or pets. Tell your children about ringworm, what to watch for and how to avoid infection.
Keep clean. Wash your hands often. Keep shared areas clean, especially in schools, child care centers, gyms and locker rooms. If you participate in contact sports, shower right after practice or a match and keep your uniform and gear clean.
Stay cool and dry. Don't wear thick clothing for long periods of time in warm, humid weather. Avoid excessive sweating. Avoid infected animals. The infection often looks like a patch of skin where fur is missing. If you have pets or other animals, ask your veterinarian to check them for ringworm.
Don't share personal items. Don't let others use your clothing, towels, hairbrushes, sports gear or other personal items. And don't borrow such things.
Treatment options include:
- Topical antifungal application
- Oral antifungal capsules or tablets
- Keeping the affected area clean and dry.
