What are the signs of a systematic infection?

A systematic infection, often referred to as a systemic infection, involves the body as a whole rather than being localized in one area. The signs of a systemic infection typically include nausea, fever, and general malaise. Fever occurs as the body's immune response to fight off the infection, indicating that the body is under stress. Nausea can accompany the systemic response as the body reacts to the infection, often leading to a loss of appetite. General malaise serves as a general feeling of unease or fatigue, which is common when the body is battling an infection.

Localized signs, such as redness and pus, are typically associated with localized infections and inflammation rather than a systemic illness. Similarly, dizziness and confusion can indicate more severe complications or other conditions but are not definitive signs of a systemic infection on their own. Thus, the correct identification of nausea, fever, and general malaise reflects a comprehensive understanding of how systemic infections manifest in the body.
