What is a foot fungal infection?
A fungal infection (mycosis) is caused by microscopic fungi. On the feet, there are two main types: cutaneous mycosis (athlete's foot), which affects the skin between the toes and on the sole, and nail mycosis (onychomycosis), which affects the toenail.
These infections are common and contagious. They thrive in warm, moist environments (swimming pools, changing rooms, enclosed footwear) and require appropriate treatment to be effectively eliminated.
