H1n1 Influenza In Children

What is H1N1 influenza?

H1N1 influenza (swine flu) is an infection caused by a virus. H1N1 influenza is easily spread when an infected person coughs, sneezes, or has close contact with others. Your child may be able to spread H1N1 influenza to others for 1 week or longer after signs or symptoms appear.

What are the signs and symptoms of H1N1 influenza?

Severe symptoms are more likely in children younger than 5. They are also more likely in children who have heart or lung disease, or a weak immune system. Signs and symptoms include the following:

  • Fever and chills

  • Headaches, body aches, earaches, and muscle or joint pain

  • Dry cough, runny or stuffy nose, and sore throat

  • Loss of appetite, nausea, vomiting, or diarrhea

  • Tiredness

  • Fast breathing, trouble breathing, or chest pain

How is H1N1 influenza diagnosed?

Your child's healthcare provider will examine your child. Tell him if your child has health problems such as epilepsy or asthma. Tell him if your child has been around sick people or traveled recently. A sample of fluid is collected from your child's nose or throat and tested for the H1N1 influenza virus.

How is H1N1 influenza treated?

Most healthy children get better within a week. Medicines used to treat H1N1 influenza include:

  • Acetaminophen: This medicine decreases pain and fever. You can buy acetaminophen without a doctor's order. Ask how much and how often to give it to your child. Follow directions. Acetaminophen can cause liver damage if not taken correctly.

  • NSAIDs help decrease swelling and pain or fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If your child takes blood thinner medicine, always ask if NSAIDs are safe for him. Always read the medicine label and follow directions. Do not give these medicines to children under 6 months of age without direction from your child's doctor.

  • Antivirals: This is given to fight an infection caused by a virus.

What are the risks of H1N1 influenza?

H1N1 influenza can cause serious or life-threatening health problems in some children. If your child is not treated for H1N1 influenza, his signs and symptoms may get worse. He may have a high fever and get dehydrated. If he has other health problems, such as asthma or epilepsy, these problems may get worse. Infection may spread to other parts of his body, such as his ears, throat, or sinuses. He may get pneumonia, bronchiolitis, or croup, and he may not be able to breathe. He may get encephalopathy (a brain disease) or meningitis (swelling of the brain coverings). He may have seizures. He may have swelling of the heart or a severe infection.

How can I manage my child's symptoms?

  • Have your child rest: Make sure your child gets enough rest and sleep. Rest and sleep may help him get better faster.

  • Give your child plenty of liquids: Ask your child's healthcare provider how much liquid your child should drink each day and which liquids are best for him. This can help prevent dehydration.

  • Use a cool-mist humidifier: This can be used in your child's bedroom to increase air moisture. It may make it easier for your child to breathe.

How can I help prevent the spread of H1N1 influenza?

  • Have your child wash his hands often: Have him use soap and water or gel hand cleanser when there is no soap and water available. Teach him not to touch his eyes, nose, or mouth unless he has washed his hands first.

  • Teach your child to cover his mouth when he sneezes or coughs: Have him cough into a tissue or his shirtsleeve so he does not spread germs.

  • Clean shared items: Clean toys, table surfaces, doorknobs, and light switches with a germ-killing cleaner. Do not share towels, silverware, and dishes with people who are sick. Wash bed sheets, towels, silverware, and dishes with soap and water.

  • Wear a face mask: Wear a mask to cover your mouth and nose when you are near your sick child. This can decrease your risk of getting H1N1 influenza. Ask healthcare providers where to buy single-use masks.

  • Keep your child home if he is sick: Keep your child away from others as much as possible while he recovers.

  • Influenza vaccine: This vaccine helps prevent influenza (flu). Everyone older than age 6 months should get a yearly influenza vaccine. Get the vaccine as soon as it is available, usually in October or November each year.

When should I contact my child's healthcare provider?

  • Your child's symptoms get worse.

  • Your child has new symptoms, such as muscle pain or weakness.

  • You have questions or concerns about your child's condition or care.

When should I seek immediate care or call 911?
