摘要:High rates of absences from influenza-like-illness (ILI) resulted in closure of a Kentucky school district for 4-days during the 2012-2013 influenza season. We calculated average daily rates of household ILI as recalled in paper surveys by parents for the weeks before, during, and after the closure. Average daily rates of ILI in the district that closed were not significantly reduced when compared with rates in 2 surrounding school districts that did not close.
