Fungal Infections
Itchy, ring-like or scaly patches caused by superficial fungal growth.
What is Fungal Infections?
Superficial fungal infections affect the skin, nails and scalp. They are common in warm, humid conditions and in areas that stay moist, such as body folds and between the toes.
Symptoms
- Itchy, ring-shaped patches with an active edge
- Scaling, cracking or peeling skin
- Discoloured or thickened nails
- Recurrence in the same areas
Common Causes
- Warm, humid environments and heavy sweating
- Tight or non-breathable clothing
- Sharing towels, footwear or personal items
- Incomplete or interrupted previous treatment
- Misuse of combination steroid creams
Who May Be Affected
Fungal infections are widespread, particularly in humid climates, and often affect multiple members of a household.
Diagnosis
Diagnosis is clinical and may be confirmed with a simple skin or nail sample examined in the laboratory when the picture is unclear or treatment has failed.
Treatment Options
- Topical antifungal therapy for localised infection
- Oral antifungal medication for extensive or resistant cases
- Longer courses for nail and scalp involvement
- Household and clothing hygiene measures
- Stopping inappropriate steroid-containing creams
Prevention & Skincare Advice
- Keep skin folds dry and wear loose cotton clothing
- Dry thoroughly after bathing
- Do not share towels, combs or footwear
- Complete the full prescribed course
When to See a Dermatologist
