Tinea pedis

Tinea pedis (also known as "athlete's foot") is a fungal infection that primarily affects the foot. It is caused by a group of fungi known as dermatophytes, which thrive in warm, moist environments.

Causes

Tinea pedis is caused by a variety of dermatophytes, including Trichophyton, Epidermophyton, and Microsporum. These fungi feed on keratin, a protein found in the outer layer of skin, hair, and nails. The infection is commonly spread in communal areas where people walk barefoot, such as showers, locker rooms, and swimming pools.

Symptoms

The symptoms of tinea pedis can vary, but often include itching, stinging, and burning between the toes or on the soles of the feet. Other symptoms may include:

• Blisters on the feet
• Cracking and peeling skin on the feet, most commonly between the toes and on the soles
• Dry skin on the soles or sides of the feet
• Raw skin on the feet
• Discolored, thick, and crumbly toenails
• Toenails that pull away from the nail bed

Diagnosis

Tinea pedis is typically diagnosed by a physical examination of the foot. In some cases, a skin biopsy may be taken to confirm the diagnosis. The sample is then examined under a microscope or cultured in a lab to identify the specific type of fungus causing the infection.

Treatment

Treatment for tinea pedis usually involves topical antifungal medications, such as terbinafine or clotrimazole. In severe cases, oral antifungal medications may be prescribed. It's important to keep the feet dry, as the fungi that cause tinea pedis thrive in moist environments.

Prevention

Prevention strategies for tinea pedis include:

• Keeping the feet dry and clean
• Changing socks regularly
• Wearing shoes that allow the feet to breathe
• Using antifungal powders
• Avoiding walking barefoot in communal areas
