By catching one: An infection is a condition in which a germ enters your body and causes it harm. There are three main categories of germs: viruses, bacteria, and fungi. Fungi are full single cells that can join together into threads. If these enter your body, you can get a fungal infection. You get them by contact with someone who has a fungal infection or just fungus on their skin.
