What are fungal skin infections (tinea)?
Tinea refers to a group of common fungal infections that affect the skin, hair, or nails. They are caused by dermatophyte fungi, which thrive in warm, moist environments. These infections are often named based on the body area affected, such as tinea corporis (body), tinea pedis (feet/athlete’s foot), and tinea cruris (groin/jock itch).
Tinea can affect anyone, but it is more common in people who sweat heavily, wear tight clothing, or share personal items such as towels or footwear. While not usually dangerous, fungal infections can be uncomfortable, itchy, and persistent if untreated.
What causes tinea?
- Dermatophyte fungi (Trichophyton, Microsporum, Epidermophyton species)
- Warm, humid environments that allow fungi to grow
- Sharing personal items (towels, shoes, sports equipment)
- Minor skin injuries or compromised skin barrier
- Immune suppression increases susceptibility
Common triggers:
- Damp shoes or socks
- Hot, humid climates
- Sweating after exercise
- Skin-to-skin contact in communal areas (gyms, swimming pools)
What are the common symptoms of tinea?
You may notice:
- Circular or ring-shaped red patches with clearer centre (tinea corporis)
- Scaling, cracking, or peeling of skin (tinea pedis)
- Itching, burning, or discomfort
- Nail thickening, discoloration, or crumbling if nails are affected (onychomycosis)
- Rash spreading slowly over weeks if untreated
How are tinea infections diagnosed?
Diagnosis is primarily clinical:
- Visual inspection of rash, scaling, and lesion shape
- Symptom history and risk factors
- Skin scraping or nail clippings may be sent for fungal culture if diagnosis is uncertain
Online GP consultations are suitable for initial assessment and treatment advice. In-person review may be needed if:
- Infection is severe or extensive
- Nail involvement is complicated
- Response to treatment is poor
How long does tinea last?
- Mild skin infections: 2–4 weeks with treatment
- Nail infections: several months due to slow nail growth
- Untreated infections can persist or recur
Is tinea contagious?
Yes. Fungal infections can spread through:
- Direct skin-to-skin contact
- Shared personal items (towels, shoes)
- Contaminated surfaces in communal areas
