Respiratory syncytial virus RSV

The respiratory syncytial virus, also called RSV, is a highly contagious viral infection that is common in young children. There is no way to avoid this infection, even though most people are exposed to it throughout the year. Those at highest risk include premature babies or young children whose immune systems have not fully developed.

RSV affects the respiratory system and may cause coughing, fever, and congestion similar to other common cold symptoms. However, the severity is much worse. Many children need to be admitted to the hospital to receive treatment.

RSV is itself a viral infection, so antibiotics are generally not helpful. However, RSV infections weaken the immune system allowing other bacterial infections to develop. In those situations, antibiotics are appropriate to prevent complications such as bronchitis or pneumonia.

Steroids may be used in children who develop wheezing or asthma-like symptoms. Bronchodilators are inhalers that can be provided to help open up the airways.

If your child is very ill and you suspect RSV, go immediately to your pediatrician's office or the nearest emergency room. Your pediatrician or emergency room doctor will order a chest x-ray and blood work after an appropriate physical examination to determine the causes of your child's infection.
