|
| · | Although a wide variety of viral agents are capable of causing LRTI in adults and children, respiratory syncytial virus (RSV), adenovirus, influenza A and B, and parainfluenza 1, 2, and 3 cause 80-90% of LRTIs
|
| · | RSV and influenza are viruses associated with significant annual morbidity and mortality, and which have available therapies
