Title: The US 2009 A(H1N1) influenza epidemic: quantifying the impact of school openings on the reproductive number.

Authors: Huang, Karen E; Lipsitch, Marc; Shaman, Jeffrey; Goldstein, Edward

Published In Epidemiology, (2014 Mar)

Abstract: There is limited information on differences in the dynamics of influenza transmission during time periods when schools are open compared with periods when they are closed.Data on school openings, influenza surveillance, and absolute humidity were incorporated into a regression model to estimate the increase in the reproductive number for the 2009 A(H1N1) influenza pandemic associated with the opening of school in 10 US states.The estimate for the average increase in the reproductive number for the 2009 A(H1N1) influenza pandemic associated with the beginning of the school year was 19.5% (95% credible interval = 10%-29%).Whether schools are open or closed can have a major impact on community transmission dynamics of influenza.
