Prognosis of Flu Discussion

Most people who get the flu recover completely in 1 to 2 weeks, but some people develop serious and possibly life-threatening complications. While your body is busy fighting off the flu, you may be less able to resist a second infection. Older people and people with chronic illnesses run the greatest risk of getting secondary infections, especially pneumonia. In an average year, flu leads to about 20,000 deaths nationwide and many more hospitalizations. (Source: excerpt from What to Do About the Flu -- Age Page -- Health Information: NIA)
