Fungal infections are very common throughout the world. In humans, fungal infections occur when an invading fungus takes over an area of the body and when it is tough for the immune system to handle. Fungi can live in the soil, plants, water, and air. Even some fungi naturally live in the human body. Fungal diseases in humans are called mycoses; they include such disorders as coccidioidomycosis, histoplasmosis, and blast mycosis. Although these diseases can be mild, characterized by an upper respiratory infection, they can also be severe, involving the bloodstream and every organ system.
