"Doctor, I have a red, circular rash around my groin and thighs. It's very itchy, and I can't sleep at night. It got worse after I applied a steroid cream a friend gave me, Doctor," 26-year-old Kamal told Dr. Priya at the clinic, recounting his ordeal.
Dr. Priya calmed her down and kindly explained, "Kamal, this is not ordinary eczema. In medical terms, this is called Tinea or a fungal infection. It is also commonly called 'Ringworm'. Steroid creams should never be used on fungal infections like this. They reduce the skin's immunity and the fungus spreads even faster. This can be completely cured with proper antifungal treatment."
What is tinea, or fungal infections of the skin? In this article, we will briefly discuss its types, symptoms, transmission, and possible medical treatments.
What are tinea fungal infections?
Tinea is a contagious fungal infection that occurs on the skin, nails, and scalp. It is also known as ringworm . However, it is not a disease caused by worms at all, but is caused by a fungal infection.
This fungus grows rapidly in warm and moist areas of the body (public bathrooms, swimming pools, and in creases where sweat accumulates due to tight clothing).
❓ Types of Tinea
Tinea is known by different names depending on where the infection occurs in the body:
- Tinea Pedis (Athlete's foot): Itching, dry, cracked, and odorous skin on the soles of the feet and between the toes.
- Tinea Cruris (Jock itch): Severe itching and red spots that appear on the thighs, buttocks, and groin.
- Tinea Capitis (Scalp Ringworm): A fungal infection of the scalp. It causes hair loss and bald spots, and rarely, pus-filled cysts (kerions) can form.
- Tinea Corporis (ringworm): Circular, red, scaly patches that appear on the hands, feet, and body.
- Tinea Unguium (Nail Fungus / Onychomycosis): Thickening of the nails, discoloration (yellowing/browning) and decay.
🤒 What are the symptoms?
- Ring-shaped, red spots on the skin with slightly raised edges.
- Scaly skin and severe itching on the surface of the spots.
- Dry and cracked skin (especially on the soles of the feet and between the toes).
- Circular patches of hair loss on the scalp.
👥 How are fungal infections transmitted?
Tinea is a highly contagious disease. It can be spread in the following ways:
1. Person-to-person: Direct skin contact with an infected patient.
2. From animals to humans:By touching animals such as dogs, cats, cows, or goats that have this fungus.
3. Through items: Sharing towels, combs, bedding, or clothing used by the patient.
4. Public places: Walking barefoot in public bathrooms or pool areas.
⚠️ Serious Dangers of Using Steroid Creams (Red Flags)
Avoid applying steroid creams such as Betamethasone, Clobetasol, or Hydrocortisone, which many people obtain from pharmacies without a doctor's prescription, to treat fungal infections.
- Result: Steroids suppress the skin's local immunity.
- Danger: Although the itching may initially subside temporarily, the fungus can spread unhindered into the skin and the disease can become very severe (Tinea Incognito).
- Scalp infections: If fungal infections of the scalp are not treated properly, they can lead to a severe, pus-filled inflammation called kerion and permanent baldness.
🛠️ Action Steps to Control Tinea Fungus Infection
- Step 1: If you develop a circular, itchy rash, see a doctor immediately to confirm whether it is a fungal infection.
- Step 2 (Apply): Apply an antifungal cream containing Clotrimazole, Miconazole, or Terbinafine, as directed by your doctor, twice a day, extending about 2 cm around the area.
- Step Three (Time): After the spot heals, continue to apply the cream for about another week to completely kill the fungus.
- Step Four (Hygiene): Dry your body thoroughly (especially the groin, armpits, and between your toes) after bathing. Do not share towels or clothes with family members.
- Step Five (Household Cleaning): Wash your clothes and bedding in hot water and dry them in the sun before using them. Clean the floor and toys with disinfectant.
📊 Comparison of Antifungal Treatments
| Drug type (Type) | Common chemical names (Active Ingredients) | How it is used |
|---|---|---|
| Topical | Clotrimazole, Miconazole, Terbinafine cream and powder. | For minor fungal infections of the skin, apply twice a day for 2-4 weeks. |
| Oral pills | Fluconazole, Itraconazole, Terbinafine tablets. | For severe fungal infections of the scalp, nails, or throughout the body, take for 2-12 weeks as directed by a doctor. |
| Antifungal shampoo | Ketoconazole shampoo. | Use 2-3 times a week to control the spread of scalp infections. |
❓ Some other questions you may have (FAQ)
Is ringworm really a worm? ▼
No. This is not a disease caused by a worm. It is called ringworm because it appears as a ring-shaped spot on the skin, but it is purely a fungal infection.
Is it okay to take oral pills for yeast infections during pregnancy? ▼
No. Oral antifungals for fungal infections during pregnancy should only be taken when absolutely necessary and under the advice of a specialist. In most cases, it is safe to use only topical creams during pregnancy.
Can fungal infections from pets be transmitted to humans?▼
Yes. People can get fungal infections from touching dogs and cats, especially if they have loose fur. Therefore, you should wash your hands with soap and water after touching your pets and seek veterinary care for your animals.
How to distinguish between a fungal infection (Tinea) and eczema? ▼
Eczema is not contagious and its lesions are not round. However, tinea versicolor is contagious and the edges of the lesions are clearly circular. Also, steroid creams are effective for eczema, but applying steroids to tinea versicolor can worsen the condition.
