You may think of the flu as pretty harmless. Most of the time, it is. People typically recover after about a week or two without any lasting problems. But sometimes, the flu can lead to serious complications requiring emergency care.
The CDC estimates that 200,000 people in the U.S. are hospitalized because of the flu every year. Thirty-six thousand die. Infants, the elderly, and people with certain diseases or weakened immune systems are the most vulnerable. But a flu emergency can happen to anyone.

Who's at Risk for a Flu Emergency?
Usually, you don't need to see the doctor if you get the flu. Your body will fight off the virus on its own with rest. But sometimes you -- or a family member -- may develop serious complications as a result of the flu. Those at increased risk of flu-related complications include:
