Athlete's foot (Tinea pedis)

Athlete's foot (tinea pedis) is a fungal infection of the skin of the foot between the toes, which if left untreated can spread to other parts of the feet and nails. This fungal disease is most common in athletes or people who spend most of the day in sports shoes, which favors the development of infection.



This disease is very difficult to treat given the very poor, wet environment where your feet are. The disease is usually transmitted from others, in humid environments when walking barefoot. Also, you can get it if you wear someone else's shoes or use means of hygiene of an infected person. If the treatment does not begin in a timely and adequate manner, the infection can spread to the soles of the feet and toenails. Through touch, the patient can spread infection to other parts of the body.

Athlete's foot is more common in people whose feet are increasingly sweating. It can be spread by wearing shoes or using items of personal hygiene of an infected person.
