The Gates Foundation became a major financial partner of DHIS2 (District Health Information Software 2), an open-source health management information platform developed at the University of Oslo. DHIS2 is now deployed in more than 70 countries covering over 40 percent of the global population, serving as the primary data collection backbone for routine health surveillance, disease tracking, and system performance monitoring. Gates funding supported its adoption across sub-Saharan Africa, where it became the standard platform for tracking immunisation coverage, malaria cases, maternal health indicators, and outbreak signals.
