It has been recognized for many years that people 65 years and older are at greater risk of serious complications from the flu compared with young, healthy adults. It's estimated that 90 percent of seasonal flu-related deaths and more than 60 percent of seasonal flu-related hospitalizations in the United States each year occur in people 65 years and older. This is because human immune defenses become weaker with age. So influenza can be a very serious disease for people 65 and older. Here are some actions to take this flu season:
- Get Your Flu Shot. The best way to prevent the flu is with a flu vaccine. CDC recommends that everyone 6 months of age and older get a seasonal flu vaccine as soon as it becomes available in your community. Vaccination is especially important for people 65 years and older because they are at increased risk for complications from flu. A flu vaccine protects against flu viruses that research indicates will be most common during the season. (See Vaccine Virus Selection for this season’s exact vaccine composition.) The vaccine has been updated for this season and immunity wanes over a year, so you should get vaccinated this year even if you were vaccinated last season. Immunity sets in about two weeks after vaccination.
- Practice good health habits including covering coughs, washing hands often, and avoiding people who are sick.
- Seek medical advice quickly if you develop flu symptoms to see whether you might need medical evaluation or treatment with antiviral drugs. It's very important that antiviral drugs be used early to treat flu in people who are very sick with flu (for example, people who are in the hospital), and people who are sick with flu and have a greater chance of getting serious flu complications, like people 65 and older (see box for full list of high risk persons/conditions).
Flu symptoms include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people may also have vomiting and diarrhea. People may be infected with the flu and have respiratory symptoms without a fever.
