Athlete’s foot is a very common skin condition - many people will develop it at least once in their lives. It occurs mostly among teenage and adult males, and is much less common in women and in children under the age of 12. Athlete’s foot can usually be easily treated, but even after successful treatment, it may come back again.
Athlete’s foot is a fungus infection of the feet. The correct term for athlete’s foot is linea pedis. The germs that cause it are called fungi. They are tiny plant-like cells that can grow and multiply on human skin. The fungi grow best in a dark, moist and warm environment.
