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 2018 alone, 510,000 [300,000-740,000] young people between the ages of 10 to 24 were newly infected with HIV, of whom 190,000 [59,000-380,000] were adolescents between the ages of 10 and 19. To compound this, most recent data indicate that only 19 per cent of adolescent girls and 14 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 delay to be initiated on life-saving treatment. Additionally, AIDS-related deaths among adolescents have increased over the past decade while decreasing among all other age groups, which can be largely attributed to a generation of children infected with HIV perinatally who 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 2018

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.

Spectrum/EPP estimate modelling

UNAIDS, WHO and UNICEF are using the Futures Institute’s modelling software, Spectrum/EPP, to generate estimates, which support policy decisions concerning public health. Spectrum includes modules for HIV estimates and projections.

Nationally representative surveys

Multiple Indicator Cluster Surveys (MICS), Demographic and Health Surveys (DHS), AIDS Indicator Surveys (AIS), reproductive health surveys, sexual behaviour surveys and other nationally representative surveys are currently used to collect data on HIV and AIDS.
