Common types Ringworm may form a circular scaly rash. Athlete’s foot affects the feet and spaces between toes. Jock itch affects the groin, while yeast can affect moist skin folds.
Diagnosis Many rashes resemble fungal infection, including eczema and psoriasis. A dermatologist may examine skin scrapings when the diagnosis is uncertain or treatment has failed.
Treatment Localized infection may respond to topical antifungal medicine used for the full recommended duration. Scalp, nail, widespread or resistant infection often needs oral medication and medical supervision. Steroid creams used alone can disguise and worsen fungal infection.
Prevention Keep folds and feet dry, change sweaty clothing, avoid sharing towels and footwear and treat infected household members or pets when advised. Seek care for spreading infection, pus, fever, diabetes, reduced immunity or scalp hair loss.
