Flu in Children

Influenza, or flu, is a contagious respiratory infection caused by influenza viruses. It can cause fever, chills, body aches, headache, fatigue, cough and other respiratory symptoms.

Influenza A and influenza B viruses cause most seasonal flu. Other respiratory viruses can produce similar symptoms, so symptoms alone do not always identify influenza.

When to see a doctor

Contact your pediatrician or another healthcare professional if:

You think your child has flu and they are very young or have a condition that raises their risk of complications.
Your child is not drinking well or shows signs of dehydration.
Fever or cough improves and then returns or becomes worse.
Your child develops breathing trouble, chest pain or severe weakness.

Call 911 or get emergency care if:

Your child has severe trouble breathing or ribs pulling in with each breath.
Your child’s lips or face turn blue or gray.
Your child is not alert, cannot be woken normally or has a seizure.
You think your child has a life-threatening emergency.
