Respiratory Syncytial Virus (RSV) Infection - Symptoms

When a respiratory syncytial virus (RSV) infection affects the nose and throat (upper respiratory system camera.gif), symptoms are usually mild and resemble those of the common cold. They include:

Babies may have additional symptoms, including:

  • A decreased interest in their surroundings.
  • Listlessness and sleepiness.
  • Fretfulness (irritability) and not sleeping well.
  • Poor feeding.
  • Apnea, where breathing stops for about 15 to 20 seconds. This usually occurs only in babies who were born prematurely and who also have a history of apnea.

It is hard to distinguish between a common cold and RSV infection. But unless you or your child has an increased risk of complications from RSV, it usually is not important to know which virus causes symptoms.

RSV infection sometimes leads to bronchiolitis or pneumonia or both.

Symptoms of these complications include:

  • Difficulty breathing, which may include breathing more rapidly than normal.
  • Wheezing.
  • Coughing that is getting worse. A child may choke or vomit from intense coughing.
  • Lethargy, increased tiredness, decreased interest in surroundings, or loss of interest in food.
