Fungal infections are common skin conditions that may cause redness, itching, burning and scaling. They can also cause blisters or peeling. Fungus can grow anywhere on the body, but tends to develop in warm, moist areas such as the feet, groin and armpit area. Common types of fungal infections include athlete's foot, jock itch, ringworm and yeast infections.
Fungal infections can usually be successfully treated with antifungal oral or topical medications. They are not usually serious, but may be contagious, so treatment is important. Keeping the body clean and changing socks and underwear everyday can help prevent fungal infections.
