Athlete's foot is a very common fungal infection of the foot. This condition is a form of ringworm that's also known as tinea pedis. The same fungus can also infect the scalp (tinea capitis), the skin (tinea corporis), or the groin (tinea cruris or jock itch). This infection gets its name because it often affects athletes, but anyone can get it, regardless of gender, age, or physical activity level. At some point, up to 70% of men and women develop athlete's foot, which usually begins between the toes.The fungus that causes athlete's foot is found everywhere, including clothing, shoes, showers, and floors. The fungus will only infect skin when conditions are right, which means a moist and warm environment often found in shoes. Signs of athlete's foot can include dryness, cracking, and redness between the toes as well as blisters and itching.
While athlete's foot is contagious, it can be treated with an over-the-counter medication in most cases. When the condition has led to fissures or cracks in the skin, a prescription will likely be necessary. A doctor's visit is not always necessary for athlete's foot, but it is important for people who have diabetes or a weakened immune system. Without treatment, the fungal infection will get worse over time and may spread to other areas like the hands.
