Atheletes foot/ Ringworm/ Tinea

Tinea is a fungal infection caused by dermatophytes — a type of mold that infects the skin, nails, or hair.
Common conditions such as athlete’s foot (mizumushi) and ringworm (tamushi) are types of tinea.

• Tinea pedis (Athlete’s foot)
– Moist, peeling, or itchy skin between the toes.
– In some cases, thickened and scaly skin appears on the soles or heels.
• Tinea unguium (Nail fungus / Onychomycosis)
– Nails become white or yellowish, thickened, brittle, or crumbly.
• Tinea corporis (Ringworm)
– Circular red rash with clearer centers and raised, spreading edges — giving a “ring-like” appearance.
– Usually appears on the body, arms, or legs and is itchy.
– Can be transmitted from infected animals (cats or dogs) through fur or dander.
• Tinea capitis (Scalp ringworm)
– Causes round bald patches and dandruff-like scaling on the scalp.
– More common in children.

• Diagnosis is made by collecting a small skin or nail sample and microscopically confirming the presence of fungi.
• It is important to distinguish from similar conditions such as eczema or psoriasis.

• Topical antifungal medication (ointment or cream)
– Used for mild tinea pedis or tinea corporis.
– Must be applied daily and continued for several weeks after improvement to prevent recurrence.
• Oral antifungal medication
– Used for nail fungus or widespread infections.
– Treatment may take several months or longer depending on the severity.

• Keep the affected areas clean and thoroughly dry every day.
• Avoid sharing towels, slippers, or bath mats to prevent family transmission.
• Nail fungus rarely heals on its own — untreated cases can spread infection to family members, so early treatment is recommended.
