A fungal infection, also called mycosis, is a skin disease caused by a fungus.
There are millions of species of fungi. They live in the dirt, on plants, on household surfaces, and on your skin.
Sometimes, they can lead to skin problems such as rashes or bumps.
Risk factors for fungal skin infections include weakened immune systems, living in warm and moist environments, sharing personal items, and having certain medical conditions like diabetes or obesity.
