    You can take steps to avoid catching or spreading the flu.

    Stay in your apartment, dorm room, or home for at least 24 hours after any fever is gone. Wear a mask if you leave your room.

    Avoid sharing food, utensils, cups, or bottles. Cover your cough with a tissue and throw away after use. Carry hand sanitizer with you. Use it often during the day and always after touching your face.

    Cough into your sleeve if a tissue is not available. Avoid touching your eyes, nose, and mouth.

    Children older than 6 months, adolescents, and adults should get a flu shot every year.

    The vaccine used in the 2010 - 2011 flu season will also protect against swine (H1N1) flu. The vaccine is available as a flu shot or a nasal spray-type flu vaccine.

    For specific recommendations, see influenza vaccine.
