RSV

By:  Joe M. Lee, M.D.

From late November through March, many infants and young children contract Respiratory Synctial Virus (RSV).  RSV causes bronchiolitis, and inflammation of the smallest airways and bronchiole. Swelling of the airways and thick secretions may result in wheezing and occasionally, severe breathing problems.  Babies with RSV can have severe coughing spasms or sound like they are choking, and a few may require hospitalization.

Premature infants, particularly those who have experienced respiratory problems, are most likely to develop severe symptoms, and may be given a new preventative treatment during RSV season to help them resist infection.  Antibiotics are not helpful against the virus, but may be given if ear infections or pneumonia develop.

To help your child resist infection:

1.  Avoid crowds.  Day care is a common source of this highly contagious virus, even with the careful precautions taken by our local day care providers.  Large crowds, such as at ball games are equally risky.

2.  Avoid tobacco smoke.  Ask people not to smoke in your house.  Smoke is very irritating to tiny airways and can reduce resistance to the virus.

3.  Wash your hands frequently, especially if you have a cold.  Many adults with RSV only experience mild cold symptoms, but can spread the germ to young children.

4.  Ask other parents to not bring sick children to visit.  Protecting your child from a serious infection is worth risking hurt feeling.

RSV can start as a cold, and older children may not get worse.  With infants, however, call your pediatrician if you notice a worsening deep cough, difficulty breathing, wheezing or shortness of breath.  During this winter season, be alert for signs of RSV.  If at all possible, take steps to avoid exposure and call your doctor if your baby has symptoms.
