Does your Child Have Flu? Symptoms, Diagnosis, and What to Do

What is the Flu in Children?

The flu is a common illness caused by the influenza virus. It spreads easily, especially during flu season in the US. Children can catch the flu at school, daycare, or even at home. Because child flu symptoms can appear quickly, it is important for parents to know what to look for. The flu can make children feel very sick, but most recover with proper care.

Common Symptoms of Flu in Children

Flu in children often starts suddenly. While symptoms can vary, many children show several signs at once. Here are the most common child flu symptoms:

  • High fever (often above 101°F or 38.3°C)
  • Chills or shivering
  • Cough, usually dry
  • Sore throat
  • Runny or stuffy nose
  • Body aches or muscle pain
  • Headache
  • Feeling very tired or weak
  • Sometimes, vomiting or diarrhea (more common in children than adults)
  • Because symptoms can be strong, children may want to rest more than usual. However, not every child will have all these symptoms.

    How to Tell Flu from a Common Cold

    Sometimes, it is hard to know if your child has the flu or just a cold. Yet, there are some key differences. For example, flu symptoms often come on quickly, while cold symptoms appear slowly. In addition, the flu usually causes a higher fever and more body aches. Here is a quick comparison:

  • Flu: Sudden high fever, severe aches, chills, and tiredness
  • Cold: Mild fever (or none), runny nose, sneezing, and mild cough
  • Because both illnesses can look similar, watch for how fast symptoms appear and how sick your child feels.

    When to See a Doctor

    Most children recover from the flu at home. However, some signs mean you should call a doctor right away. According to the CDC, seek medical help if your child:

  • Has trouble breathing or fast breathing
  • Looks blue or pale
  • Is not drinking enough fluids
  • Cannot wake up or interact
  • Has a fever with a rash
  • Shows signs of dehydration (no tears when crying, dry mouth, or no urine for 8 hours)
  • Gets better, then suddenly gets worse
  • Because young children and those with health problems are at higher risk, do not wait if you are worried. When in doubt, call your healthcare provider.

    Diagnosis and Testing

    Doctors can often diagnose flu in children based on symptoms. Sometimes, they may use a quick test by swabbing your child’s nose or throat. However, not every child needs a test. During flu season, doctors may treat based on symptoms alone. If your child is very sick or at high risk, testing may help guide treatment.

    Home Care and Treatment

    Most children with the flu can recover at home. Here are some helpful tips for caring for your child:

  • Let your child rest as much as needed
  • Offer plenty of fluids like water, soup, or juice
  • Use a cool-mist humidifier to ease breathing
  • Give fever medicine like acetaminophen or ibuprofen (never aspirin)
  • Keep your child home from school until they feel better
  • Because antibiotics do not work on viruses, they will not help the flu. Sometimes, doctors may prescribe antiviral medicine if your child is at high risk or very sick. Always follow your doctor’s advice on medicine and care.

    Prevention Tips for Parents

    While the flu can spread easily, you can help protect your child. Here are some simple steps:

  • Get your child a yearly flu vaccine
  • Teach your child to wash hands often with soap and water
  • Remind your child to cover coughs and sneezes with a tissue or elbow
  • Keep sick children at home until they are fever-free for 24 hours
  • Clean and disinfect surfaces often, especially during flu season
  • Because the flu vaccine is safe and effective, it is the best way to prevent flu in children.
