- People who have a weakened immune system (such as from HIV/AIDS, cancer, chemotherapy, diabetes, or certain medications)
- Use of public showers or locker rooms
- Athletes involved in contact sports, such as wrestling
- Excessive sweating in tight shoes
- Close contact with affected animals such as household pets
- Working with soil that has ringworm fungus
- Living in a warm, humid climate
- Close contact with a person who is infected
- Sharing bedding, towels, or clothing with a person who is infected
How Is Athlete’s Foot Diagnosed?
Athlete’s foot (tinea pedis) is often diagnosed with a physical examination of the affected skin.
Tests that may be indicated to diagnose athlete’s foot include:
- Skin scraping to be examined under a microscope or sent to a laboratory for a fungal culture
- Ultraviolet light

How Do You Prevent Athlete’s Foot?
To prevent athlete's foot (tinea pedis)
- Do not share clothing, sports equipment, or towels with other people
- Always wear slippers or sandals at the gym, local pool, or other public areas (including the shower)
- Wash thoroughly with soap after any sport involving skin-to-skin contact
- Avoid tight-fitting clothing
- Wear a clean pair of socks every day
- Put socks on before putting on underwear so the infection does not spread to other parts of the body
- Keep the skin clean and dry and always dry off completely after bathing
- For pets: if your pet has patches of missing hair or a rash take them to the vet because it could be a sign of a tinea infection
