Impact of contact investigation programs on LTBI prevalence cases in 2011 (A) and cases of endogenous TB reactivation between 2001 and 2061 (B). Numbers within bars indicate the average percent reduction with respect to a passive-only diagnosis program. An expanded description of each program is reported at the end of section Methods. Average and 95-percentile error bars for the model are calculated over 100 best parameter set and 100 stochastic simulations of the model.
