Season of infant bronchiolitis and estimates of subsequent risk and burden of early childhood asthma

Kecia N Carroll et al. J Allergy Clin Immunol. 2009 Apr.

Abstract

There is a population-based increased risk of early childhood asthma following infant bronchiolitis occurring during rhinovirus-predominant months compared to asthma following infant bronchiolitis during RSV-predominant months.

Observed proportion and 95% CI of developing asthma by season of infant bronchiolitis. November-April represents the six month wintervirus season; December-February represents the RSV-dominant period within wintervirus season. May-October represents the six month non-wintervirus season; May, August, and September represents the RV-dominant period within non-wintervirus season. The total number of infants with bronchiolitis is indicated in parentheses for each period.
