Influenza, commonly known as the flu, is a viral respiratory infection characterized by symptoms that often include fever. Fever is a hallmark sign of influenza and is typically one of the first symptoms to appear. It is often accompanied by other flu symptoms such as cough, sore throat, body aches, fatigue, and congestion. Influenza can range from mild to severe, and in some cases, it can lead to complications, especially in vulnerable populations like the elderly, young children, and individuals with underlying health conditions. Vaccination is a key preventive measure to reduce the risk of contracting the flu and its associated fever.
