Everyone 6 months and older should get a yearly flu vaccine. Avoid close contact with sick people. Stay home when you are sick and limit your contact with others. Cover your mouth and nose with a tissue when coughing or sneezing. Wash your hands often with soap and water. Avoid touching your eyes, nose, and mouth.
