Protecting Kids from the Flu: Signs, Prevention, and What to Do

Updated January 2026

As a parent, keeping your child healthy is a top priority. With flu season upon us, it's crucial to be well-prepared. In this article, we'll cover the signs and symptoms of the flu in children, steps to take if they get sick, prevention tips, as well as emergency signs to watch out for in both children and infants.

Flu Symptoms and Prevention for Infants and Children

Flu symptoms in kids can come on fast, often within a day. Because the flu spreads easily, prevention is the best way to protect children and keep them healthy. It is not too late to get a flu shot. The vaccine is safe, helps prevent serious illness, and starts working in about two weeks. Other important steps include washing hands often, covering coughs and sneezes, cleaning shared surfaces, and keeping sick children home from school and activities. The sooner your child is vaccinated, the sooner they are protected. Call your child’s primary care provider now to schedule a flu shot.
 

Recognizing Signs and Symptoms of the Flu

Flu symptoms in children often resemble those in adults but can be more severe. Watch out for these common signs:

  • Fever
  • Cough
  • Fatigue
  • Body Aches
  • Headache
  • Chills and Sweating

Steps to Take if Your Child Gets the Flu

If your child displays flu symptoms, you can lessen the length of illness and avoid the spread if you follow a few simple steps. First, keep them home from school or daycare. Then, ensure they get plenty of rest and drink fluids to stay hydrated. If necessary, acetaminophen or ibuprofen (as directed by your healthcare provider or the packaging) can help reduce fever and ease discomfort. In some cases, a healthcare provider may prescribe antiviral drugs, especially if symptoms are severe. In general, keep a close eye on their symptoms and seek medical attention if they worsen or if they have underlying health conditions.

When to Seek Medical Attention for the Flu

In some cases, the flu can lead to severe complications. Keep an eye out for these emergency signs:

For Children:

  1. Fast Breathing or Difficulty Breathing: If your child is breathing rapidly or struggling to breathe, seek immediate medical attention.
  2. Bluish Skin: Bluish lips, face, or extremities can be a sign of oxygen deprivation. Seek immediate medical attention.
  3. Severe Dehydration: If your child is not drinking enough and shows signs of severe dehydration (dry mouth, no tears when crying), contact your healthcare provider.

For Infants:

  1. Difficulty Breathing: If your infant is breathing rapidly, grunting with each breath, or flaring their nostrils, seek immediate medical attention.
  2. Poor Feeding and Severe Dehydration: If your child is not drinking enough and shows signs of severe dehydration (dry mouth, no tears when crying), contact your healthcare provider.
  3. Lethargy: If your baby is unusually sleepy and unresponsive, seek immediate medical attention.

Remember, early intervention is crucial when it comes to the flu. Keep your child vaccinated, practice good hygiene, and stay informed about emergency signs. If in doubt, consult a healthcare professional for guidance tailored to your child's specific needs. Your vigilance can help keep your little one healthy during flu season.
