moccasin-type infection

The term "moccasin-type infection" refers to a specific presentation of athlete's foot, a fungal infection of the feet. This type of infection is characterized by redness and thickening of the skin on the soles and sides of the feet, often appearing on both feet simultaneously. It is caused by dermatophytes, a group of fungi that thrive on keratin, a protein found in skin, hair, and nails.1

Athlete's foot is a common condition, with an estimated 70% of people experiencing it at some point. Risk factors include exposure to warm, moist environments like locker rooms and public showers, excessive sweating (hyperhidrosis), and immune system disorders. While many fungi can cause infections, Trichophyton rubrum is the most frequent culprit for athlete's foot. Treatment typically involves topical antifungal medications, though severe cases may require oral medication.12
