Infection refers to the body reacting to a microbe or pathogen. It is somewhat distinct from “inflammation” but there is much overlap: infection and inflammation often occur together, and inflammation in the absence of infection may often become infected later. Infection categories by pathogen include viral infections, bacterial infections, fungal infections, parasites, and other types. Infections are often categorized by affected body region or system: respiratory infection, lung infection, digestive infection, skin infection, ear infection, eye infection, throat infection, and many other types.
