TB REACH works with a number of partners around the world, including governmental and non-governmental institutions, funding agencies, implementers, academia and others at national, regional and international level. Although each collaboration takes a different form and format, their common purpose is to maximize the potential and impact of TB REACH, its experiences and best practices for improved TB case detection and TB health service delivery. Individual partnering institutions in this section do not represent an exhaustive list but are rather intended to give an overview of some of TB REACH’s most important and official, contract-based partnerships.
