When my 4 year old had RSV when he was 5 weeks old, also on a
vent for 11 days, (he had RSV a
second time when he was 2 1/2 in
the hospital 5 days no vent.) they said he could end up having asthma. Every time we go see the pulmonologist *sorry if I spelled it wrong, they ask how often does he couh at night. None, doen't cough in the day time either only when he is sick.
So from what I was told and understand it does sound like he has asthma.
