Children in preschool and school-age groups are frequently observed to amplify transmission of many forms of flu (Bell 2006, Germann 2006), and are often the first mechanism for introducing transmission into the home (Cedron 2006). Despite the propensity of influenza epidemics to be amplified in primary schools, data on the effectiveness of school closures are limited (Bell 2006), especially in recent years, and the impact of school closures on illness rates appears to be mixed (Ingelsby 2006).
