Impact of Viral Respiratory Infections on Pulmonary Exacerbations in Children with Cystic Fibrosis.

In this single pediatric CF center cohort, one-third of PEs requiring hospitalization were associated with a viral infection, with rhinovirus/enterovirus being the most common. Viral-positive PEs were not associated with a greater decline or delayed recovery of lung function, increased risk for PA acquisition, shortened duration to next PE, longer hospital stay, or an increase in frequency of subsequent PEs in 6 months compared to viral-negative PEs.
