Causes
Athlete’s foot
Athlete’s foot is primarily caused by dermatophytes, specifically the fungi Trichophyton rubrum, Trichophyton interdigitale, and Epidermophyton floccosum. These fungi thrive in warm, moist environments, making the feet, particularly between the toes, an ideal location for infection. The fungi can spread through:
- Direct Contact: Coming into contact with an infected person.
- Contaminated Surfaces: Walking barefoot on contaminated floors, such as those in locker rooms, swimming pools, and communal showers.
- Shared Items: Using towels, socks, or shoes that have been used by someone with athlete’s foot.
Risk Factors
Several factors can increase the risk of developing athlete’s foot:
- Wearing Enclosed Footwear: Tight, non-breathable shoes create a warm, moist environment that promotes fungal growth.
- Sweating Heavily: Excessive moisture from sweat can increase the likelihood of fungal infection.
- Walking Barefoot in Public Areas: Locker rooms, saunas, and swimming pools are common places for the fungus to spread.
- Sharing Personal Items: Using shared towels, socks, or shoes with an infected person increases the risk of transmission.
- Minor Skin or Nail Injuries: Small cuts or abrasions on the feet can provide an entry point for the fungi.
