Pediatric HealthSource: RSV

Mike Patrick, M.D.

Q: My daughter has been diagnosed with RSV, and I'm worried it's getting more serious. What are the signs and symptoms of RSV, and when should I seek medical attention if it worsens?

A: Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis and pneumonia in children younger than age 1. Almost all babies get RSV—most of them before they are 2 years old—and knowing the signs and symptoms can help catch it early and start the proper course of treatment for your child.

For healthy children, RSV is similar to getting a cold: symptoms include a stuffy or runny nose, sneezing, sore throat and fever. When a child is exposed to RSV, the virus infects cells in the upper and lower respiratory tracts, resulting in a surplus of mucus. This excess mucus clogs the nose and airways, making it difficult to breathe.

Antibiotics do not kill the virus. Treatment consists of symptom relief and supportive care. Parents can use a cool-mist humidifier to make breathing easier and reduce coughing, give plenty of liquids and use saline nose drops and a bulb syringe to loosen a stuffy nose. Acetaminophen or ibuprofen can be given to relieve fever, but never give a child aspirin.

For some children, RSV can be very serious. Contact your pediatrician if your child has a fever higher than 101 degrees; a cough lasting more than four days; thick, yellow, green or gray mucus coming from the nose or mouth; chest pain; or trouble breathing.

Always consult your child's pediatrician concerning your child's health.

Prevention

Some children are more susceptible to catching RSV than others. Those with lung problems and premature infants have a higher risk. To prevent RSV, parents should know:

??Adults get RSV, too.While it may be easier to fight off when you are older, RSV can cause serious harm when spread to infants.

??Take precautions when sick. If you catch a cold, sneeze or cough into a tissue away from your child and wash your hands frequently.

??Always keep things clean. Disinfect toys, baby products and other items frequently to prevent the spread of germs.
