Overview

Infection of the toe web, commonly known as interdigital tinea pedis or athlete’s foot, is a fungal infection that affects the skin between the toes. It is typically caused by dermatophytes, a group of fungi that thrive in warm, moist environments, making the areas between the toes particularly susceptible. The condition often presents with symptoms like itching, burning, scaling, and sometimes painful cracks or sores. It can occur due to walking barefoot in communal areas like pools or gyms, or from wearing tight, non-breathable footwear. The infection can spread to other parts of the foot and, if left untreated, may lead to more serious complications such as secondary bacterial infections.

Toe web infections are quite common, especially among athletes and individuals who frequently engage in activities that cause their feet to sweat. It also occurs more frequently in people with weakened immune systems, diabetes, or those who have poor foot hygiene. Cases can range from mild to severe, with severe cases leading to maceration of the skin and secondary bacterial infections, which may cause significant discomfort and require more intensive treatment.

Treatment for toe web infections typically involves antifungal medications, which can be administered topically or orally, depending on the severity of the infection. Topical antifungals such as clotrimazole, miconazole, or terbinafine are often effective in clearing mild cases. In more severe cases, oral antifungals like terbinafine or itraconazole may be prescribed. Additionally, keeping the feet clean, dry, and well-ventilated is crucial to prevent recurrence. Over-the-counter antifungal powders or sprays can also help in maintaining dryness and preventing the spread of the infection. If a secondary bacterial infection is present, antibiotics may be necessary.
