The role of regional health diplomacy on data sharing. The SADC and UNASUR cases

English abstract: Health governance has become multi-layered as the combined result of decentralization, regional integration and the emergence of new actors nationally and internationally. Whereas this has enhanced the installed capacity for health response worldwide, this complexity also poses serious challenges for health governance, health diplomacy and health policy-making. This article focuses on one of these challenges, namely the organization of statistical information flows at and between governance levels, and the emerging role that regional organizations play therein. Regional to national-level data flows are analyzed with the use of two case studies focusing on UNASUR (Bolivia and Paraguay) and SADC (Swaziland and Zambia). The results of the analysis lead to several policy recommendations at the regional and national levels.
