Specific species of fungi have evolved to grow preferentially on hair, skin and nails. Sources of infection include cats, dogs, rats, cattle, sharing infected towels, sheets, clothing, hats, hairbrushes, going barefoot in public places, dirt, occlusive footwear, and nail salons. Most fungal skin infections are superficial and are limited to the top layer of skin.
Many individuals are infected with fungus and are asymptomatic. Only when they are exposed to hot, humid conditions do they become symptomatic and/ or notice the appearance of a rash. Infected skin may appear lighter in color, red or a reddish tan discoloration compared to normal skin.
Topical antifungal treatments are generally effective, but oral medication may be necessary in some instances.
