Dhobi itch

Dhobi itch, also known as tinea cruris or jock itch, is a common dermatophyte infection that primarily affects the groin area. It is a type of fungal infection caused by a group of molds called dermatophytes, which live on the dead tissues of the skin, hair, and nails.

Causes

Dhobi itch is caused by a type of fungus called Trichophyton rubrum. This fungus thrives in warm, moist areas of the body, such as the groin, inner thighs, and buttocks. It is more common in men and adolescents, and is often associated with excessive sweating and tight clothing.

Symptoms

The main symptom of dhobi itch is a red, itchy rash in the groin area. The rash often has a ring-like appearance and may be flaky or scaly. Other symptoms can include burning or itching in the affected area, a change in skin color, and a foul odor.

Diagnosis

Dhobi itch is usually diagnosed based on the appearance of the rash. A dermatologist may also take a skin scraping to examine under a microscope or culture in a laboratory to confirm the diagnosis.

Treatment

Treatment for dhobi itch typically involves topical antifungal medications, such as clotrimazole or terbinafine. In severe cases, oral antifungal medications may be needed. Good hygiene practices, such as keeping the area clean and dry, wearing loose-fitting clothing, and changing underwear daily, can also help prevent and treat dhobi itch.

Prevention

Prevention of dhobi itch involves maintaining good personal hygiene, avoiding tight clothing, and keeping the groin area clean and dry. Using antifungal powders or creams can also help prevent the infection.
