Current status + progress
Turning the tide against AIDS will require more concentrated focus on adolescents and young people
Adolescents and young people represent a growing share of people living with HIV worldwide. In 2019 alone, 460,000 [260,000-680,000] young people between the ages of 10 to 24 were newly infected with HIV, of whom 170,000 [53,000-340,000] were adolescents between the ages of 10 and 19. To compound this, most recent data indicate that only 27 per cent of adolescent girls and 16 per cent of adolescent boys aged 15-19 in Eastern and Southern Africa – the region most affected by HIV – have been tested for HIV in the past 12 months and received the result of the last test. The testing rates in West and Central Africa and South Asia are even lower. If current trends continue, hundreds of thousands more will become HIV-positive in the coming years, and without knowing their status, adolescents will miss out on life-saving treatment. Additionally, a large population of children infected with HIV perinatally over the last decade are growing into adolescence.
In 2015, UNICEF and UNAIDS, in partnership with other international health and development partners, launched ALL IN! to End Adolescent AIDS. This global initiative established 2020 targets towards ending the AIDS epidemic among adolescents by 2030. To achieve this, it is critical to accelerate efforts to address the epidemic among adolescents.
Data sources + methodology
Global AIDS monitoring 2020
In order to monitor the HIV response and progress towards achieving global goals, countries submit national and subnational data on a host of indicators to the Global AIDS Monitoring (GAM) system. Annual submissions are reviewed and validated. Data consist of programmatic data for HIV prevention, testing and treatment. Other indicators require data from population-based surveys and surveys focused on key populations at risk of HIV infection.

UNAIDS Estimates and Spectrum’s AIDS Impact Model
Each year countries update their AIDS Impact Model in Avenir Health’s Spectrum software to develop the latest estimates for the HIV epidemic. Supported by UNAIDS, WHO and UNICEF these estimates are used to inform programme and policy decisions for HIV epidemic response.
Methods for HIV modelling are developed by the UNAIDS Reference Group on Estimates, Modelling and Projections.
All available data on HIV estimates are available at aidsinfo.unaids.org.
Nationally representative surveys
Multiple Indicator Cluster Surveys (MICS), Demographic and Health Surveys (DHS), AIDS Indicator Surveys (AIS), Population-based HIV Impact Assessments (PHIA) reproductive health surveys, sexual behaviour surveys and other nationally representative surveys are currently used to collect data on HIV and AIDS.
