What is systemic and localised infection?

A systemic infection is one that affects the entire body, often spreading through the bloodstream and impacting multiple organs or systems, which can lead to widespread symptoms like fever and fatigue. In contrast, a localized infection is confined to a specific area of the body, such as a wound or an organ, and typically results in localized symptoms like redness, swelling, and pain. Understanding the distinction between the two is crucial for diagnosis and treatment.
