Flu fever, also known as influenza fever, is a symptom commonly associated with influenza virus infection. It is characterized by an elevated body temperature above the normal range, typically presenting as temperatures above 100°F (37.8°C). Flu fever can manifest alongside other flu symptoms such as chills, body aches, fatigue, headache, and respiratory symptoms like cough and sore throat.

The fever is the body’s natural response to the presence of the flu virus. When the immune system detects the virus, it releases chemicals called pyrogens, which reset the body’s thermostat to a higher temperature. This elevated temperature helps create an environment less favorable for viral replication and can aid in the body’s immune response to fight off the infection.

Flu fever can vary in intensity and duration depending on the individual’s immune response and the severity of the viral infection. In some cases, fever may last for several days, accompanied by other flu symptoms. Proper hydration, rest, and over-the-counter fever-reducing medications like acetaminophen or ibuprofen can help manage flu fever and alleviate associated discomfort.

However, it’s essential to monitor flu fever closely, especially in high-risk individuals such as young children, older adults, pregnant women, and those with underlying health conditions. Seek medical attention if fever persists or worsens, or if other severe symptoms develop, as these could indicate complications requiring medical intervention.
