BackgroundActive case finding (ACF) for tuberculosis (TB) can reduce transmission, yet efficient targeting requires high-quality surveillance data. We investigated the potential costs and impact of targeted ACF, guided by local estimates of the annual risk of TB infection (ARTI) derived from Mycobacterium tuberculosis (Mtb) immunoreactivity survey data in children aged <5 years. MethodsUsing mathematical models parameterized with local data, we compared three case-finding approaches across 33 u...
