How to tell when you have athlete's foot and what to do about it

Insider featured Jason Rizzo, research assistant professor in the Jacobs School of Medicine and Biomedical Sciences at UB, in an article about symptoms and treatment of athlete’s foot. The fungus thrives in any moist or humid environment. Rizzo said that these fungal infections typically remain on the outer layers of the skin and are usually mild and easily treatable. He added that athlete’s foot is mildly contagious and can be spread directly through contact with infected skin, or indirectly through items like towels, shoes or floors. Cats and dogs can also carry the fungus and be a source of infection.
