|Comparison of school-based with clinic-based indicators|
|Summary measure||School type||Clinic-based indicators†||School-based indicators, per 100 school children‡|
|Cumulative incidence in entire period||Pri||34||21||0.24||32||25|
|Cumulative incidence up to week 30||Pri||17||10||0.15||15||13|
|Fraction of cumulative incidence occurring up to week 30||Pri||50%||49%||63%||48%||51%|
All data has been rounded off to 2 significant figures.
†Incidence data for GP-ILI is expressed as the number of ILI consults per GP per week, while that for GP*Lab-ILI is the number of ILI consults per GP per week attributable to pdmH1N1, as derived by multiplying GP-ILI with the weekly proportion of ILI samples positive for pdmH1N1.
‡Sch-LCC is based on notifications of laboratory confirmed cases of pdmH1N1 by all schools, Sch-FRI is self-reported febrile respiratory illness in the 6 sentinel schools, and Sch-FRI-adj is Sch-FRI adjusted to remove possible contribution from non-pdmH1N1 causes using FRI incidence from week 38 as a proxy for baseline incidence.
