10 Vital Signs of Pneumonia You Mustn’t Overlook

2. Fever

High fever, often accompanied by chills and sweating, is a common indicator of pneumonia.

Fever is a common indicator of pneumonia. When the body detects an infection, such as pneumonia, it often responds by raising its temperature to help fight off the invading microorganisms. This immune response leads to fever, which is characterized by an elevated body temperature above the normal range (typically around 98.6°F or 37°C).

In the case of pneumonia, the infection causes inflammation in the air sacs of the lungs, leading to the accumulation of fluid and mucus. This inflammatory process triggers the body’s immune system, resulting in symptoms like fever. The fever associated with pneumonia can range from mild to high, depending on the severity of the infection and the individual’s immune response.
