What is a symptom of a localized infection?

Localized infections typically manifest symptoms that are confined to a specific area of the body rather than affecting the entire system. The presence of localized redness and swelling is a key indicator of inflammation in response to infection. This localized reaction occurs as the body directs immune cells to the site of infection, leading to increased blood flow which causes redness, warmth, and swelling in the affected area.

While high fever, general malaise, and severe headache can be associated with infections, these symptoms are more indicative of systemic infections, where the body's immune response is activated throughout. In contrast, localized symptoms are specific to the involved tissue and are essential for identifying infections that are not widespread.
