Influenza (Child)

Influenza is also called the flu. It is a viral illness that affects the air passages of your lungs. It is different from the common cold. The flu can easily be passed from one to person to another. It may be spread through the air by coughing and sneezing. Or it can be spread by touching the sick person and then touching your own eyes, nose, or mouth.

Symptoms of the flu may be mild or severe. They can include extreme tiredness (wanting to stay in bed all day), chills, fevers, muscle aches, soreness with eye movement, headache, and a dry, hacking cough.

Your child usually won’t need to take antibiotics, unless he or she has a complication. This might be an ear or sinus infection or pneumonia.

Home care

Follow these guidelines when caring for your child at home:

  • Fluids. Fever increases the amount of water your child loses from his or her body. For babies younger than 1 year old, keep giving regular feedings (formula or breast). Talk with your child’s healthcare provider to find out how much fluid your baby should be getting. If needed, give an oral rehydration solution. You can buy this at the grocery or pharmacy without a prescription. For a child older than 1 year, give him or her more fluids and continue his or her normal diet. If your child is dehydrated, give an oral rehydration solution. Go back to your child’s normal diet as soon as possible. If your child has diarrhea, don’t give juice, flavored gelatin water, soft drinks without caffeine, lemonade, fruit drinks, or popsicles. This may make diarrhea worse.

  • Food. If your child doesn’t want to eat solid foods, it’s OK for a few days. Make sure your child drinks lots of fluid and has a normal amount of urine.

  • Activity. Keep children with fever at home resting or playing quietly. Encourage your child to take naps. Your child may go back to daycare or school when the fever is gone for at least 24 hours. The fever should be gone without giving your child acetaminophen or other medicine to reduce fever. Your child should also be eating well and feeling better.

  • Sleep. It’s normal for your child to be unable to sleep or be irritable if he or she has the flu. A child who has congestion will sleep best with his or her head and upper body raised up. Or you can raise the head of the bed frame on a 6-inch block.

  • Cough. Coughing is a normal part of the flu. You can use a cool mist humidifier at the bedside. Don’t give over-the-counter cough and cold medicines to children younger than 6 years of age, unless the healthcare provider tells you to do so. These medicines don’t help ease symptoms. And they can cause serious side effects, especially in babies younger than 2 years of age. Don’t allow anyone to smoke around your child. Smoke can make the cough worse.

  • Nasal congestion. Use a rubber bulb syringe to suction the nose of a baby. You may put 2 to 3 drops of saltwater (saline) nose drops in each nostril before suctioning. This will help remove secretions. You can buy saline nose drops without a prescription. You can make the drops yourself by adding 1/4 teaspoon table salt to 1 cup of water.

  • Fever. Use acetaminophen to control pain, unless another medicine was prescribed. In infants older than 6 months of age, you may use ibuprofen instead of acetaminophen. If your child has chronic liver or kidney disease, talk with your child’s provider before using these medicines. Also talk with the provider if your child has ever had a stomach ulcer or GI (gastrointestinal) bleeding. Don’t give aspirin to anyone younger than 18 years old who is ill with a fever. It may cause severe liver damage.

Follow-up care

Follow up with your child’s healthcare provider, or as advised.

When to seek medical advice

Call your child’s healthcare provider right away if any of these occur:

  • Your child has a fever, as directed by the healthcare provider, or:

    • Your child is younger than 12 weeks old and has a fever of 100.4°F (38°C) or higher. Your baby may need to be seen by a healthcare provider.

    • Your child has repeated fevers above 104°F (40°C) at any age.

    • Your child is younger than 2 years old and his or her fever continues for more than 24 hours.

    • Your child is 2 years old or older and his or her fever continues for more than 3 days.

  • Fast breathing. In a child age 6 weeks to 2 years, this is more than 45 breaths per minute. In a child 3 to 6 years, this is more than 35 breaths per minute. In a child 7 to 10 years, this is more than 30 breaths per minute. In a child older than 10 years, this is more than 25 breaths per minute.

  • Earache, sinus pain, stiff or painful neck, headache, or repeated diarrhea or vomiting

  • Unusual fussiness, drowsiness, or confusion

  • Your child doesn’t interact with you as he or she normally does

  • Your child doesn’t want to be held

  • Your child is not drinking enough fluid. This may show as no tears when crying, or "sunken" eyes or dry mouth. It may also be no wet diapers for 8 hours in a baby. Or it may be less urine than usual in older children.

  • Rash with fever
