RSV (respiratory syncytial virus) or bronchiolitis

The respiratory syncytial virus affects your child’s nose, sinuses, throat and lungs. RSV is the most common cause of bronchiolitis and pneumonia among infants and children younger than one year old.

Your child can get RSV more than once. Because RSV is caused by a virus, antibiotics won’t help. The virus must run its course.

Symptoms of RSV are:

  • congestion and nasal drainage
  • loss of appetite
  • cough that won’t go away
  • wheezing (whistling sound) when breathing
  • fever (sometimes)

How to make your child feel more comfortable

  • For an infant, use a rubber syringe bulb to remove any mucus in her nose. This will be helpful before each feeding and before sleep.
  • Give your child lots of clear liquids. For infants, give Pedialyte®. You may need to give small amounts of liquids more often. Watch how often your child urinates to see if she needs more to drink.
  • Do not stop breastfeeding or formula feeding.
  • Keep your child away from secondhand smoke.

When to call your health care provider

To avoid awkward sentences, instead of referring to your child as "he/she" or "him/her," this guide will alternate between "he" or she" and "him" or "her."
