The flu is caused by viruses that infect the nose, throat, and lungs. You can take many steps to reduce your risk of contracting the flu or spreading the flu to others.

• When you are sick, cover your nose and mouth with a tissue when you sneeze or cough. If you don't have a tissue, sneeze or cough into your upper sleeve, not your hands. Promptly put tissues into a wastebasket or plastic bag.
• After coughing or sneezing, always wash your hands with soap and water or clean them with an alcohol-based hand sanitizer.
• If you are sick, stay home so you don't risk spreading the virus to other people.
• Avoid close contact with people who are sick if possible.
• Avoid touching your eyes, nose, or mouth. You can spread germs picked up from doorknobs, tables, or other surfaces.
• Wash your hands often with soap and water or use an alcohol-based hand cleaner.
• Stay healthy by eating well-balanced meals, getting enough sleep, and exercising regularly.
