Monitoring the global HIV epidemic and the response is a core function of UNAIDS. The Secretariat supports countries in their annual reporting of programme, behavioural, financial and epidemiological data through the GAM system. The response rate has remained roughly stable since 2012, with 174 Member States (90%) reporting in 2017. Experts among Cosponsors and global partners are consulted to maintain high-quality and up-to-date reporting and analysis methodologies. The Monitoring Technical Advisory Group (MTAG) develops the GAM indicator set and guidelines used by countries to report progress.

UNAIDS Secretariat continues to support countries to develop estimates of the impact of HIV on their population. In 2017, estimates were produced for 170 countries representing almost 99% of the global population. The UNAIDS Reference Group on Estimates, Modelling and Projections reviews the HIV estimates model annually to ensure it is based on the latest science and statistical methods, and therefore more accurate estimates of epidemiological indicators, including trends in HIV incidence. In 2017 the Secretariat trained more than 500 country-based individuals on using estimation and projection software to better understand their epidemic. The Secretariat worked with WHO to improve estimates of TB incidence and deaths among people living with HIV and the collection and analysis of country data. Country teams worked with global experts using a model to develop district-level age and sex specific estimates of the HIV burden for 10 high-burden countries.


Key achievements are;

The Global AIDS Monitoring System

  • 174 Member States (90%) reporting in 2017
  • trained over 500 country-based individuals on how to use estimation and projection software to better understand their epidemic
  • novel model to develop district level age and sex specific estimates of HIV burden for 10 high-burden countries

8 countries joined the Situation Room initiative (Kenya, Cote d’Ivoire, Lesotho, Mozambique, Namibia, Uganda, Zambia and Zimbabwe)

  • collect real-time data from sub-national level
  • guide responses using a location-population approach that focuses human and financial resources on the geographic locations and populations in greatest need

Country data into policy recommendations 

  • Do no harm report, 2016
