What to do for 2009 H1N1 flu

  • Keep germs from spreading.
    • Make sure everyone washes their hands often. Wash with soap and warm water for at least 20 seconds (about as long as 1 to 2 verses of the "Happy Birthday" song). Alcohol-based hand rubs should be limited to times when soap and water are not available. Keep these products out of the reach of children and supervise their use.
    • Cough and sneeze into a tissue or into your elbow or upper sleeve.
    • Use tissues for wiping runny noses and to catch sneezes. Throw them in the trash right after each use.
    • Try not to touch your eyes, nose, or mouth.
    • Anyone who is sick should stay home and limit contact with others.
    • Keep a child home from school or child care until the fever is gone for at least 24 hours without taking fever-reducing medicine. Normal body temperature is different for each child and may range from 97°F (36.1°C) to 100.3°F (37.9°C). In general, a temperature of 100.4°F (38°C) or higher may be a sign of a fever. Note: Schools and child care centers may have different rules about when children need to stay home.
  • Check with your child's doctor or pharmacist if you have any questions about your child's medicine.
    • For fever or body aches, your child's doctor may suggest acetaminophen (like Tylenol) or ibuprofen (like Advil or Motrin). NEVER give your child aspirin.
    • Antiviral medicine for flu generally is given to children who are at higher risk of flu complications (such as those with chronic disease or cancer) or are in close contact with a person who has the 2009 H1N1 flu.
    • Visit the AAP Web site regularly for the latest information on the 2009 H1N1 vaccine. In the meantime, have your child immunized to protect against seasonal influenza as soon as that vaccine is available.
  • Other ways to help your child
    • Make sure your child drinks plenty of liquids to avoid getting dehydrated.
    • Encourage and help your child rest.
    • Stay informed because information is continually being updated. Know what's going on in your area and follow the recommendations of public health authorities.
