Effectiveness of default school closure strategies. All parameters involved take the reference values: generation time Tg = 2.7 days, effective reproduction number Re = 1.4, relative susceptibility to infection of adults with respect to underaged individuals = 0.2, probability of becoming symptomatic upon infection pI = 30 %, relative transmission rate of symptomatic and asymptomatic individuals = 1, trigger for the monitoring of schools = 150 new weekly symptomatic cases, length of a single closure = 1 week, minimum interval between consecutive closures = 1 week. The panels refer to school closures where the maximum number of weeks lost is one, two, three and four respectively (see columns). Colors refer to the three default strategies considered (see legend). Means are computed over 100 stochastic model realizations. a Reduction in attack rate for the three default strategies. Dashed horizontal lines represent the interval of excess absenteeism for which the obtained attack rate reduction is at least 80 % that of the maximum. b Effective school days lost per student for the three default strategies. c Reduction in peak week incidence for the three default strategies. Dashed horizontal lines represent the interval of excess absenteeism for which the obtained peak week incidence reduction is at least 80 % that of the maximum
