The flu typically lasts about 3 to 7 days for most people, with the most severe symptoms lasting around 2 to 3 days. However, some symptoms like a cough and fatigue can linger for up to two weeks or even longer. Fever usually goes away within 3 to 4 days but may last up to 8 days in some cases. While the initial symptoms resolve, a person may still feel weak and tired during recovery. People with weakened immune systems or other conditions may experience a longer duration of symptoms and recovery time. It is advised to rest even after the worst symptoms pass to allow full recovery. If symptoms last longer than 7 to 14 days or worsen, medical advice should be sought.
