Fungal Skin Infections
Fungal skin infections, such as athlete's foot and ringworm, are common infections caused by fungi that thrive in warm, moist areas of the skin
About fungal skin infections
These infections are usually caused by dermatophyte fungi, which feed on keratin in skin, hair and nails. They spread through direct contact or contaminated surfaces (such as shared towels, socks or shower floors) and thrive in warm, sweaty environments like between the toes or in skin folds
Treatments
Symptoms
• Itchy, red or scaly patches of skin
• A ring-shaped rash with a clearer centre (ringworm)
• Cracking or peeling skin, particularly between the toes
• Soreness or a burning sensation
• Occasionally, blistering
Diagnosis
Fungal skin infections are usually diagnosed from their typical appearance. A skin scraping can confirm the diagnosis if it's unclear, doesn't respond to treatment, or affects the nails, where infection can be harder to identify visually
Treatment
Most fungal skin infections respond well to topical antifungal creams, sprays or powders used for the full course, even after symptoms improve, to prevent recurrence. Widespread, severe or nail infections may need oral antifungal tablets
Prevention and self-care
• Dry skin thoroughly, especially between toes and in skin folds
• Wear breathable footwear and change socks daily
• Avoid walking barefoot in communal areas like pools and changing rooms
• Don't share towels, shoes or clothing
• Keep skin cool and dry
• Treat affected areas promptly to avoid spreading
