Summary of the estimated effects of school closures on peak incidence of pandemic influenza (all ages) predicted by the modelling studies.

<p>Different symbols are used to reflect the assumed value for R₀. The findings are grouped according to whether they assumed that the community/household contacts increased, remained unchanged, the assumptions about contact were based on empirical data or were unclear. Some studies assumed that workplaces and/or other public places also closed <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097297#pone.0097297-Ferguson2" target="_blank">[11]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097297#pone.0097297-CruzPacheco1" target="_blank">[14]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097297#pone.0097297-CiofidegliAtti1" target="_blank">[23]</a>. All studies that stated their assumptions regarding the effects of school closure on contact patterns assumed that contacts between school-aged children were reduced or eliminated.
