What is RSV

Little babies wheeze very young kind of disease called RSV and they wheeze afterward. Does that mean they are going to be asthmatic or that the infection RSV is making them wheeze? What is that story about?

Michael Marcus: RSV is one of the most common viruses that children are infected with. In fact, within the first two years of life, virtually every child has been infected by this virus at least once. Most children who get RSV infection get nothing more than a running nose, mild cough which goes away in five to seven days. But about 25-30% of these children will go on to develop wheezing and difficulty in breathing and some of these children actually end up in the hospital to care for these episodes. What we have learned is that the children who wheeze from their RSV infection do have a higher risk of developing asthma as they get older but it is not 100% risk and so what we tell parents is that if children are wheezing from their RSV, then they need to monitor them closely over the next several years, set it out so that if asthma develops we can treat it promptly minimizing future problems.
