What is Tinea?
Tinea is a fungal infection of the skin caused by dermatophyte fungi. Despite the common name "ringworm," it has nothing to do with worms. The infection gets its name from the characteristic ring-shaped rash it can produce.
Tinea infections are very common in tropical climates like Sri Lanka due to heat and humidity. The fungi thrive in warm, moist areas of the body.
Types of Tinea
| Type | Affected Area | Common Name |
|---|---|---|
| Tinea corporis | Body (trunk, arms, legs) | Ringworm |
| Tinea pedis | Feet (between toes) | Athlete's foot |
| Tinea cruris | Groin and inner thighs | Jock itch |
| Tinea capitis | Scalp | Scalp ringworm |
| Tinea unguium | Nails | Fungal nail infection |
| Tinea versicolor | Chest, back, shoulders | Pityriasis versicolor |
Symptoms
Ringworm (Body)
- Red, circular, ring-shaped patches

How You Can Get Tinea
- Direct skin contact with an infected person
- Sharing personal items: Towels, combs, clothing, slippers
- Contact with infected animals: Dogs, cats, cattle
- Contaminated surfaces: Gym floors, bathrooms, swimming pools
- Warm, moist environments: Sweaty clothing, wet shoes, humid climate
Treatment
Managing Tinea
- Antifungal cream: Apply clotrimazole (Canesten) or miconazole cream to the affected area twice daily for at least 2-4 weeks. Continue for 1 week after the rash disappears.
- Keep the area clean and dry: Wash with gentle soap and water. Dry thoroughly, especially between toes and skin folds.
- Wear loose, breathable clothing: Cotton is best. Avoid tight synthetic clothing.
- Change clothes and socks daily: Wash infected clothing in hot water.
- Do not share personal items: Towels, razors, combs, and clothing.
- For nail infections: Oral antifungal medication (prescribed by a doctor) is usually needed as creams don't penetrate nails well.
Prevention
- Keep skin clean and dry, especially after exercise
- Wear slippers in shared bathrooms and swimming pool areas
- Change underwear and socks daily
- Avoid sharing personal items
- Treat infected pets promptly
- Use antifungal powder in shoes and skin folds during humid weather
When to See a Doctor
Seek medical attention if:
- The infection does not improve after 2 weeks of antifungal cream
- The rash is spreading rapidly or is very extensive
- Signs of bacterial infection (pus, increased pain, fever)
- Scalp or nail involvement (requires oral medication)
- You have diabetes or a weakened immune system
- The infection keeps coming back
