Diagnosis: How to Know Your Child Has Influenza

  • Influenza occurs every year in the fall and winter months. During this time, if flu symptoms occur, your child probably has the flu.
  • Your child doesn't need any special tests.
  • Call your doctor if your child is HIGH-RISK for complications of the flu. See the list below. These are the children who may need prescription anti-viral drugs.
  • For LOW-RISK children, usually you don't need to see your child's doctor. If your child develops a possible complication of the flu, then call your doctor. See the "When to Call Your Doctor" section.

HIGH-RISK Children for Complications From Influenza

Children are considered HIGH-RISK for complications if they have any of the following:

  • Lung disease (such as asthma)
  • Heart disease (such as a congenital heart disease)
  • Cancer or weak immune system conditions
  • Neuromuscular disease (such as muscular dystrophy)
  • Diabetes, sickle cell disease, kidney disease OR liver disease
  • Diseases needing long-term aspirin therapy
  • Pregnancy
  • Healthy children under 2 years old are also considered HIGH-RISK (CDC 2009)
  • Note: All other children are referred to as LOW-RISK

Prescription Antiviral Drugs for Influenza

  • Antiviral drugs (such as Tamiflu) are sometimes used to treat influenza. They must be started within 48 hours when the flu symptoms start.
  • The AAP recommends they be used for any patient with severe symptoms. They also recommend the drugs for most HIGH-RISK children. See that list.
  • The AAP doesn't recommend antiviral drugs for LOW-RISK children with mild flu symptoms.
  • Their benefits are limited. They usually reduce the time your child is sick by 1 to 1.5 days. They reduce the symptoms, but do not make them go away.
  • Side effects: Vomiting in 10% of children.

Return to School

  • Your child can return to school after the fever is gone for 24 hours. Your child should feel well enough to join in normal activities.
  • Spread is rapid. The time it takes to get the flu after contact is about 2 days. The range is 1 to 4 days. The virus is easily passed to others.
