If your baby had an attack of severe RSV, she or he is 2.5 times more likely to develop asthma over the next 5 years.  A Nationwide Children’s Hospital-Ohio State University study analyzed data from nearly 125,500 infants over a 16 year period.

 

This association between childhood RSV and asthma has been previously described, but this large study credibly confirms it.  There is a controversy about the nature of the association.  Does  more severe RSV lead to a longstanding reactive airway that is asthma or is an infant with a reactive airway tendency more likely to contract RSV.  The old chicken and egg dilemma.

 

Whichever is true, an infant having had RSV should be watched carefully for asthma.
