Underestimation of influenza viral infection in childhood asthma exacerbations.

摘要

Bocavirus was found in 11.6% of hospitalized children and 13% of ambulatory patients with exacerbations of asthma, and respiratory syncytial virus was found in 13.5% and 17.7%, respectively. In addition, influenza A virus was detected in 2.6% of hospitalized children and 14.1% (P<.001) of ambulatory-treated patients. Thus, the influenza burden in asthma may be underestimated.
