Red, itchy skin that’s hard to ignore—even in public? You might think it’s eczema, but skin conditions vary widely. Atopic dermatitis in eczema can mimic tinea symptoms, leading to confusion. Early stages are often mild, so many head to the pharmacy for self-treatment ointments. But mistaking tinea for eczema and using steroids recklessly could worsen it. Learn the key differences between eczema and tinea, plus smart medication choices—Bowtie breaks it down for you below to keep your skin healthy and protected.
What is Ringworm? Types in Hong Kong
Ringworm is common in Hong Kong, caused by fungal infections (mold-like parasites) that thrive in moist and warm environments 1 . Hong Kong’s humid and stuffy summers create the perfect breeding ground for these fungi, making it peak season for ringworm. These fungi can invade the skin’s outer layer, hair, and nails, leading to various types of tinea. Think of it like everyday items getting moldy – that’s ringworm on your skin.
Common types of ringworm in humans include the following 1,2 :
| Athlete’s Foot | Commonly known as “Hong Kong Foot” , it causes blisters or dry, cracking skin between toes or on soles, with intense itching. Scratching can lead to bacterial infections with pus. |
| Nail Fungus | Known as “onychomycosis,” fungi attack toenails or fingernails, causing discoloration, deformity, thickening, and brittleness. |
| Jock Itch | Red, ring-shaped rashes with severe itching in the groin area (inner thighs). More common in overweight, sweaty men. |
| Body Ringworm | Also called “tinea corporis” or “ringworm,” it appears as one or more ring-shaped red patches on the body (like face, arms, or shoulders), with extreme itching. |
| Tinea Versicolor | Known as “pityriasis versicolor,” it shows light-colored, round, scaly patches on the back, upper chest, arms, and neck, with itching. |
Ringworm Symptoms: Is It Contagious?
People with ringworm typically experience these skin symptoms 2,3 :
- Itching and pain
- Thickened skin with darker pigmentation
- Red spots or oval red marks of varying sizes
- Dryness or blisters
- White scales and peeling on the surface
Ringworm spreads through 3 :
- Person-to-person: Usually via direct skin contact with an infected person.
- Animal-to-person: Contact with infected animals can transmit it, especially when petting cats, dogs, or grooming them – it’s also common in cows.
What’s the Difference Between Ringworm and Eczema?
Ringworm and eczema have very similar symptoms, but they differ greatly in causes, affected areas, contagiousness, and prevention measures.
Causes
Eczema is mainly triggered by exposure to environmental allergens, and those affected often have other allergic conditions like asthma or hay fever due to genetic factors. In contrast, ringworm is heavily influenced by environmental factors, especially humid and stuffy weather, or contact with infected animals or people. Additionally, malnutrition, poor personal hygiene habits—such as not changing into dry clothes promptly after sweating—skin injuries, weakened immunity, and chronic conditions like diabetes can all increase the risk of ringworm 4,5 .
Affected Areas
Eczema is a chronic skin condition that flares up intermittently and can affect localized or widespread areas. Ringworm, however, is a temporary and localized skin infection, most commonly appearing in confined spots like between the toes, fingers, underarms, groin, or inner thighs 5 .
Contagiousness
Eczema is not contagious 4 ; whereas ringworm is contagious 3 .
Prevention
Since eczema stems mainly from immune system imbalances, it can’t be prevented. Most cases of ringworm, however, are caused by environmental infections and can generally be prevented.
How to Treat Ringworm? Is Ointment Effective?
If you suspect you have ringworm, it’s best to see a doctor early. They’ll make a professional clinical judgment and prescribe the appropriate medication to treat the fungal infection.
Mild cases of ringworm can be treated with topical antifungal medications. Doctors typically prescribe ointments for a course of one to four weeks 2 . Targeted ointments come in liquid or cream forms and are applied to the affected area. For dry, cracked skin, creams are suitable, but they’re not effective for nail fungus.
For stubborn or severe fungal infections, oral antifungal medications are needed to fully eradicate it. A common one is griseofulvin, mainly for nail ringworm or body ringworm that doesn’t respond to topical ointments. Since treatment often takes a while, patience is key—stick strictly to your doctor’s instructions and complete the full course. At the same time, maintain good personal hygiene to speed up recovery and reduce the chance of recurrence.
How to Prevent Ringworm?
- Pay attention to personal hygiene—shower thoroughly, cleaning all body parts, especially skin folds and between toes 1,3
- Wear appropriate clothing to keep skin dry and ventilated, especially between fingers, toes, and in the groin area 4
- After exercise or if you sweat easily, shower frequently and dry off completely
- If you have foot ringworm, avoid foot massages, going barefoot in changing rooms, public showers, pools, or walking barefoot on park paths. Treat it early to prevent spreading to other body parts or infecting others 4
- If you touch the affected area, wash your hands immediately to avoid spreading ringworm to other parts of the body 1
- Those with athlete’s foot shouldn’t wear nylon socks—opt for cotton ones and change them often. Also, wear dry, breathable shoes. For groin ringworm, avoid tight pants like jeans
- Change socks, clothes, and towels daily. Rotate shoes and keep them dry
- Don’t share personal items like clothes, shoes, socks, combs, pillows, towels, or hair accessories 1
- Avoid scratching itchy areas to prevent inflammation, and don’t soak in overly hot water
- Keep your home clean regularly. If family members have athlete’s foot or nail fungus, clean and disinfect floors and bathtubs periodically 4
- Ringworm can easily recur, so keep clothes clean and avoid dampness
- Diabetics are especially prone to infection, so follow the hygiene tips above and manage your diabetes 1
