My son has respiratory syncytial virus. what is prognosis?

Asthma more likely: Depends OB his age. We all get RSV and most of us are showing very little symptoms. In infant patients the clinical presentation is more severe with pneumonia. Also with RSV there is evidence that the likelihood for later asthma development is increased. Generally the acute short term prognosis is good for most patients, worse for those requiring mechanical ventilation.
