Athlete's Foot Or Tinea Pedis

Athlete's foot is also known as tinea pedis. It is usually caused by fungi in the genus Trichophyton and affects the skin on the feet.
Athlete's foot is one of the most common fungal skin infections. 
Athlete's foot fungus may infect any part of the foot, but most often grows between the toes.

Causes And Risk Factors: Athlete's foot spreads easily. You can get it by touching the toes or feet of a person who has it. But most often, people get it by walking barefoot on contaminated surfaces near swimming pools or in locker rooms. The fungi then grow in the shoes, especially if the shoes are so tight that air cannot move around the feet.
Risk factors for getting infected with Athlete's foot are: 
  • Male gender
  • People who frequently wear damp socks or tight fitting shoes
  • Sharing mats, rugs, bed linens, clothes or shoes with someone who has a fungal infection
  • Walking barefoot in public areas where the infection can spread, such as locker rooms, swimming pools, communal baths and showers.
Clinical Features: Athlete's foot usually causes a scaly red rash.
