Flu season arrives with the cold weather. As we get ready for the holidays, when you'll be surrounded by family and friends, it's a good time to get a flu vaccination.
The flu is caused by viruses (germs). You can become infected when you inhale these germs directly. You can also become infected when you touch a surface on which the droplets containing germs have landed and then transfer the germs to your eyes, nose, or mouth.
What's important to remember is that anyone can get the flu. But you are more likely to become infected if:
Have a weakened immune system
Have frequent, close contact with young children
Work in a health care setting where you may be exposed to flu germs
Live or work with someone who has the flu
Haven't received an annual flu shot
Viruses that cause the flu change from year to year. For that reason, health care providers recommend getting the flu vaccine each fall or winter.
