Most skin infections have similar symptoms, like redness, itching, or rashes on the skin. The symptoms and conditions might be difficult to differentiate.
The two most common type of skin infections is eczema and ringworm. Both infection types have different causes, risk factors, and treatments.
Key Takeaways
- Eczema is a skin condition that causes red, itchy, and dry patches, while ringworm is a fungal infection that causes circular rashes.
- Eczema is not contagious, while ringworm is highly contagious and can spread from person to person or from animal to human.
- Eczema is commonly caused by genetics or environmental factors, while ringworm is caused by a fungus that thrives in warm and moist environments.
Eczema vs Ringworm
The difference between eczema and ringworm is that eczema is caused by irritants, microbes, allergens, fluctuation in temperature, and certain food products, while ringworm is caused by fungus. Eczema can spread all over the body but is most prominent in areas like the legs, hands, feet, arms, and torso, while ringworm mainly affects the feet, scalp, beard, nails, and groin.
Eczema is a skin infection found only in humans. It is not a contagious infection. Eczema has multiple patches.
The different types of eczema are atopic dermatitis, Allergic contact dermatitis, dyshidrotic eczema, neurodermatitis, discoid eczema, and stasis dermatitis.
On the other hand, ringworm is a skin infection found in humans as well as animals. It is a contagious infection. Ringworm is seen only in one or two patches.
The different types of ringworm are ringworm of the scalp, Jock itch or tinea cruris, ringworms of the body, Athlete’s foot or tinea pedis.
Comparison Table
| Parameters of Comparison | Eczema | Ringworm |
|---|---|---|
| Causes | Irritants, allergens, microbes, hot and cold temperatures, food products, stress, and hormones | Three types of fungus – Microsporum, Trichophyton, and Epidermophyton |
| Symptoms | Dry, scaly skin, itching in the skin, skin flushing, open, crusted or weeping sores | Darkening, peeling of the skin, fissures, scaly patches on the skin, red rashes, hair loss, or even itchy scalp |
| Types | Atopic dermatitis, Allergic contact dermatitis, dyshidrotic eczema, neurodermatitis, discoid eczema, stasis dermatitis | Ringworm of the scalp, Jock itch or tinea cruris, Ringworm of the body, Athlete’s foot or tinea pedis |
| Age group affected | Most common in children | Most common in children or people who own pet cats and dogs |
| Treatment | Treatment Topical corticosteroid Creams and ointment, oral medications, antibiotics, topical calcineurin inhibitors, antihistamines, phototherapy, and other injected biological drugs | Ringworm can be treated with medications like anti-fungal ointment, creams, sprays, gels, or oral antifungals like griseofulvin and lifestyle changes. |
What is Eczema?
Eczema is a condition of the skin which brings itchiness, roughness, cracks, or inflammation to the skin. Some kinds of eczema also cause blisters.
The most common type of eczema is atopic dermatitis. Eczema can be triggered by certain foods like dairy or nuts, which are allergic to the body.
Other than food triggers, there can be environmental triggers also, like soap, pollen, smoke, fragrances, and several other factors.
Eczema is not contagious. Some people have a period of symptoms that improves later, while some carry the symptoms throughout their life.
Since the skin becomes rough, dry, and itchy, it urges the patients to continuously rub and scratch the skin, leading to other skin infections or making eczema severe.
Some eczema sores and rashes appear grey or brown and later get dark or light skin patches. These patches are termed hyperpigmentation and depigmentation or hyperpigmentation.
Such patches are treated with steroid creams.
Most eczema conditions do not have a particular treatment but can be minimized with certain care like regular moisturizing, wearing softer fabrics, switching to milder soaps and washes, avoiding rubbing or scratching of the skin, and taking lukewarm baths.
Eczema conditions flare up in winter; hence extra precautions should be taken during this season. There are other topical corticosteroid creams and ointments prescribed to eczema patients.
In case of no improvement from tropical ointment, doctors prescribe oral medications, antibiotics, antihistamines, and other therapies to improve the condition.
What is Ringworm?
Ringworm refers to a fungal infection of the skin. Unlike its name, it is not a worm but a fungus. It is also known as dermatophytosis, dermatophyte infection, or even tinea.
The lesion formed resembles a worm in the shape of a ring. Skin infection is common in both humans and animals.
The skin infection appears as red patches on the skin and tends to spread to other body parts like feet, scalp, beard, nails, groin, and several other areas.
Three main fungus types are responsible for causing ringworm – Microsporum, Trichophyton, and Epidermophyton.
Most of these fungi are present in the soil as spores. Ringworm is diagnosed with a black light as the fungus closes and has fluorescence under black light.
Other tests like skin biopsy, fungal culture, or a KOH exam are also done to determine the type of fungus. Ringworm has two main stages the initial stage and the second stage. Ringworm is contagious.
Ringworm can be treated with medications and lifestyle changes. Topical medications like anti-fungal ointment, creams, sprays, or gels are prescribed to patients with ringworm.
Changes in lifestyle, like ensuring cleanliness and proper sanitization and wearing loose clothes in the affected area, can minimize the existing conditions.
Main Differences Between Eczema and Ringworm
- Eczema is not contagious, while ringworm is contagious.
- Eczema can spread all over the body, while ringworm affects certain parts of the body.
- Some eczema patches may have a burning sensation, while ringworm patches do not have any burning sensation.
- Eczema only occurs in humans, while ringworm occurs in both humans and animals.
- Eczema forms multiple patches on the skin, while ringworm forms one or two patches on the skin.
