Athlete's foot, or tinea pedis, is a common fungal infection that affects the skin on the feet. It is characterized by red, itchy, scaly, and often painful patches on the skin and between the toes. The fungus that causes athlete's foot, normally called Trichophyton rubrum, thrives in warm, moist environments, such as swimming pools, locker rooms, and showers. When these areas come in contact with the feet, the fungus can spread and cause infection.
Athlete's foot can spread quickly and easily, particularly in warm, moist environments. Individuals who wear tight, synthetic socks or shoes are also more likely to get athlete's foot, as this creates a dark, warm, and moist environment for the fungus to thrive. Those who sweat heavily or have wet feet for long periods of time due to activities such as swimming are also more likely to get athlete's foot.
Individuals with compromised immune systems, such as those with diabetes or HIV, are also more likely to get athlete's foot. The fungus that causes athlete's foot can be spread through direct contact with an infected person or by coming into contact with surfaces that have been contaminated with the fungus.
To prevent athlete's foot, individuals should wear well-ventilated, breathable shoes and socks and avoid walking barefoot in public areas. It is also important to keep feet clean and dry, as moisture encourages the growth of fungus. If an individual suspects they have athlete's foot, they should see a doctor, as over-the-counter treatments may not be effective.
