What is fungus?

A fungus is a type of organism that lives in soil, water, on plants and in the air. Mold is a common example. Some types of fungus can also live and grow on body tissues, such as the fingernails or skin, leading to an infection. Infections caused by fungus include yeast infections and ringworm infections (such as jock itch or athlete's foot). Fungus usually grows best in moist, dark areas, such as folds of skin. People with weak immune systems have a higher risk of fungal infections.
