Age-specific patterns of influenza activity in Utah: Do older school age children drive the epidemic?

Abstract

Across 12 consecutive influenza seasons in Utah, medically-attended visits for laboratory-confirmed influenza infection peaked first among older children (12-18 years). Peak activity in older children preceded that of children 0-4 years by more than 2 days and that of peak activity among adults ≥65 years by more than 6 days. © The Author 2013.
