What is an abnormal function of the body caused by infection?

An abnormal function of the body caused by infection is often referred to as a disease or illness, such as pneumonia or sepsis. Infections can disrupt normal physiological processes, leading to symptoms like fever, inflammation, and fatigue as the immune system responds to the invading pathogens. This can impair organ function and overall health, depending on the severity and type of infection. Such disruptions can vary widely, affecting various systems in the body, from respiratory to gastrointestinal.
