The Effect of School Closure on Hand, Foot, and Mouth Disease Transmission in Singapore: A Modeling Approach.

ABSTRACT: Singapore implements a school closure policy for institutional hand, foot, and mouth disease (HFMD) outbreaks, but there is a lack of empirical evidence on the effect of closure on HFMD transmission. We conducted a retrospective analysis of 197,207 cases of HFMD over the period 2003-2012 at the national level and of 57,502 cases in 10,080 institutional outbreaks over the period 2011-2016 in Singapore. The effects of school closure due to 1) institutional outbreaks, 2) public holidays, and 3) school vacations were assessed using a Bayesian time series modeling approach. School closure was associated with a reduction in HFMD transmission rate. During public holidays, average numbers of secondary cases having onset the week after dropped by 53% (95% credible interval 44-62%), and during schoo
