The severity of symptoms is related to the severity of the fever. Fever and systemic symptoms typically last 3 days, occasionally up to 4-8 days, and gradually diminish; however, cough and malaise may persist for more than 2 weeks. Second fever spikes are rare. The physical findings are summarised in table 3. Full recovery may take 1-2 weeks, or longer, especially in the elderly. Table 3. Physical findings of uncomplicated influenza. Fever: rapidly peaking at 38-40Â°C (up to 41Â°C, especially in children), typically lasting 3 days (up to 4-8 days), gradually diminishing; second fever spikes are rare.
People with the flu usually have a fever for two to five days. This is different than fever caused by other upper respiratory viruses, which usually resolve after 24 to 48 hours. Most people with the flu have fever and muscle aches, and some people also have cold-like symptoms (runny nose, sore throat). Flu symptoms usually improve over two to five days, although the illness may last for a week or more. Weakness and fatigue may persist for several weeks (table 1).
