What is a systemic infection?

Depends. A "systemic infection" can mean either than an infection has affected the whole body and many organ systems, or it can mean that the body is reacting to an infection in a localized place, like a pneumonia, with signs like fever, fast heart rate and fast breathing rate. So, it depends on what "systemic" means.
Disseminated. The word "systemic" refers to something that affects the entire body. For example, you could have a "localized" staph infection, in which the infection was confined to a skin abscess, or you could have a "systemic" staph infection, in which the bacteria was present in the blood and multiple organs. In general, systemic infections are more severe than localized infections.
