The most common fungus causing athlete's foot in humans is Trichophyton rubrum. The fungus is highly contagious and can be spread by direct contact with the skin or hair of an infected host. The fungus also spreads easily through indirect contact with contaminated clothing or surfaces.

In order to survive and grow, the fungus needs heat and humidity. So there is an increased risk of infection if the skin is exposed to warm, moist environments. Athletes are more likely to suffer from athlete's foot due to prolonged wearing of closed shoes where heat and moisture accumulate. Tinea pedis is also known as swimmer's eczema. The humid environment of a swimming pool is also a risk factor. Moreover, dermatophytes are very resistant to chlorine in swimming pools.

Have you ever suffered from athlete's foot? Then you too are more likely to get infected. Moreover, the infection occurs more often in adults than in children, in men than in women and in people with diabetes or a weakened immune system. If you suffer from excessive sweating, you are more susceptible to the infection.
