With all the media warnings out about flu season, you may be wondering what sorts of things increase your risk of catching the flu. First, if you don't get immunized against flu, you may have a higher chance of catching the flu. According to the CDC, the number one way to prevent flu is to get an annual flu vaccine (flu shot or FluMist).

Because the strain of flu virus changes over time, the influenza vaccine changes annually. That's why it's important to stay current and get a flu shot each year -- preferably during the months of October or November or before flu season begins.

Where can I get a flu shot?

The American Lung Association offers an online flu vaccine clinic locator. Visit www.flucliniclocator.org, enter your zip code and a date (or dates), and receive information about clinics scheduled in your area.

There's also a nasal flu vaccine called FluMist, which contains weakened live viruses. People with HIV/AIDS and other medical conditions that weaken the immune system should not receive the live influenza vaccine. FluMist is approved for use among healthy persons between the ages of 2 years and 49 years.

Can certain lifestyle habits increase my chance of flu?

If you have poor lifestyle habits, your body's immunity may be compromised. That can result in a greater chance of catching the flu. In addition, the chance of getting flu may increase if you have family members or coworkers with flu and touch germ-laden surfaces (doorknobs, phone receiver, computer mouse, countertops) that they have touched.

Taking better care of your health by eating a balanced diet, getting regular exercise and plenty of sleep, and managing your stress may help boost immune function and, thus, reduce your chance of flu.

What about hand washing and the risk of flu?

Frequent and thorough hand washing is crucial to reducing the risk of flu. Be vigilant about washing your hands throughout the day. Teach your family members to do the same. Keep hand sanitizers with you at all times in case you are unable to get to a sink to use warm water and soap to wash your hands.

Is my young child at greater risk for flu?

Children under age 2 years are at high risk for flu-related complications. As infants and young children grow, they are always battling with ongoing viruses and bacteria as their immune systems develop. In fact, it's normal for a young child to get as many as six to eight colds each year, along with ear infections, sinusitis, acute bronchitis, and croup, especially if the child attends daycare. When a young child is sick frequently or has a weak immune system, the child has even greater risk for catching the flu virus and having complications.
