What is influenza (the flu)?

The flu is a viral infection of the lungs and airways. The virus spreads through droplets in the air when someone with the flu coughs or sneezes. The virus also spreads through close contact with someone who has the flu. For example, a person with the virus on his or her hands can spread it by shaking hands with someone. Your child may be able to spread the flu to others for 1 week or longer after signs or symptoms appear.

What are the signs and symptoms of the flu?

Severe symptoms are more likely in children younger than 5 years. 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
• Headache, body aches, earache, 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 the flu diagnosed?

Your child's healthcare provider will examine your child. Tell the provider if your child has health problems such as epilepsy or asthma. Tell the provider if your child has traveled recently or was around anyone who is sick. A sample of fluid may be collected from your child's nose or throat to be tested for the flu virus.

How is the flu treated?

Most healthy children get better in 7 to 10 days. Your child may need any of the following:

• Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to give your child and how often to give it. Follow directions. Read the labels of all other medicines your child uses to see if they also contain acetaminophen, or ask your child's doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly.
• NSAIDs , such as ibuprofen, help decrease swelling, pain, and 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 or her. Always read the medicine label and follow directions. Do not give these medicines to children younger than 6 months without direction from a healthcare provider.
• Antivirals help treat viral infections.

How can I manage my child's symptoms?

• Help your child rest and sleep as much as possible as he or she recovers.
• Give your child liquids as directed to help prevent dehydration. Your child may need to drink more than usual. Ask your child's healthcare provider how much liquid your child should drink each day. Good liquids include water, fruit juice, and broth.
• Use a cool mist humidifier to increase air moisture in your home. This may make it easier for your child to breathe and help decrease his or her cough.Use a cool mist humidifier to increase air moisture in your home.

What can I do to prevent the spread of germs?

• Keep your child home while he or she is sick. The virus is most contagious during the first 3 to 5 days.
• Help your child wash his or her hands often. He or she should wash after using the bathroom and before preparing or eating food. Have your child use soap and water. Show him or her how to rub soapy hands together, lacing the fingers. Wash the front and back of the hands, and in between the fingers. The fingers of one hand can scrub under the fingernails of the other hand. Teach your child to wash for at least 20 seconds. Use a timer, or sing a song that is at least 20 seconds. An example is the happy birthday song 2 times. Have your child rinse with warm, running water for several seconds. Then dry with a clean towel or paper towel. Your older child can use hand sanitizer with alcohol if soap and water are not available.
• Remind your child to cover a sneeze or cough. Show your child how to use a tissue to cover his or her mouth and nose. Have your child throw the tissue away in a trash can right away. Then your child should wash his or her hands well or use hand sanitizer. Show your child how to use the bend of his or her arm if a tissue is not available.
• Tell your child not to share items. Examples include toys, drinks, and food.
• Ask about vaccines your child needs. Vaccines help prevent some infections that cause disease. Have your child get a yearly flu vaccine as soon as recommended. The vaccine is usually available starting in September or October. Your child's provider can tell you other vaccines your child should get, and when to get them.
