Fungi are everywhere. There are millions of different species of fungi on Earth, but only about 300 of those are known to make people sick. Fungal infections are often caused by microscopic fungi that are common in the environment. Fungi live outdoors in soil and on plants as well as on many indoor surfaces and on human skin.
Mild fungal skin infections can look like a rash and are very common. For example, ringworm is a skin infection caused by a fungus, not a worm! Fungal infections in the lungs can be more serious and often cause symptoms that are similar to other illnesses, such as the flu or tuberculosis. Fungal meningitis and bloodstream infections are less common than skin and lung infections but can be life-threatening. Because the symptoms of fungal infections can be similar to those of other illnesses, proper diagnosis and treatment are often delayed. The more you know about fungal infections and your chances of getting one, the better you can protect your health
