The Centers for Disease Control urges you to take the following steps to protect yourself and others from the flu:

• Vaccinate:  Take time to get the flu vaccine.  The CDC recommends a yearly vaccine as the first and most important step in protecting against this serious disease.  This is especially important for people at high risk for serious flu complications, including young children, pregnant women, people with chronic health conditions like asthma, diabetes or heart or lung disease, and people 6 years of age and older. 
• Stop Germs: Take everyday protective actions like covering your nose and mouth with a tissue when you cough or sneeze.  Throw the tissue in the trash after you use it.  Wash your hands often with soap and water, especially after coughing or sneezing.  Alcohol-based hand sanitizers are also effective. Try to avoid contact with sick people, and if you get the flu, the CDC recommends that you stay home from work or school and limit contact with others. 
• Antiviral Drugs: Take flu antiviral drugs if your doctor recommends them.  If you do get the flu, antiviral drugs are an important treatment option, but not a substitute for vaccination.  Antiviral drugs are prescription medications that can make your illness milder and make you feel better faster.  They may also prevent serious complications.
