The Centre for HIV Strategic Information is based at the Andrija Štampar School of Public Health, which is part of the University of Zagreb School of Medicine. The Centre was established as a Knowledge Hub in 2003 under the framework of the Project “Capability Strengthening for Improved Utilization of Financial Resources to Fight HIV/AIDS” and funded by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and WHO EURO. The central objective of this initiative was to support countries in the optimal access to and use of the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM) and other large grants through supporting the development of local technical capacity in launching large-scale responses to HIV. The Knowledge Hub was designated the WHO Collaborating Centre for HIV Surveillance in March 2008. The first training courses were provided during 2004. Until July 2018, over 2300 participants from 105 countries have been trained in HIV surveillance.
