How long does the flu last for an elderly person? And why it takes longer to recover

According to the CDC, adults 65 years and older are at a much higher risk of serious flu-related complications and hospitalization. While a younger, healthy person may recover in a few days, the answer to "how long does the flu last for an elderly person?" is typically longer, ranging from one to two weeks, with lingering symptoms sometimes lasting for several weeks. The longer duration is due to age-related changes in the immune system and the increased risk of complications.
