This report covers strategic information related to young people aged 15-24 years. It provides an understanding of HIV prevalence; describes the use of HIV prevention services; reports on the level of HIV knowledge; and describes behaviours among young people that impact on the spread of HIV (Section 2). The report includes a review of reporting on the UNGASS indicators for young people by region, and the status of the epidemic and response among young people using strategic information from UNGASS reporting in 2010 (Section 3). It also examines countries' policies and spending towards HIV programmes for young people (Section 4). In the regional overviews (Section 5), there is a special focus on the priority countries identified in the UNAIDS Business Case for the priority area on young people, and the indicators that will be used to assess achievement of the three bold results within the UNAIDS Business Case 2009-2011. The primary target audience of this report are programme managers and policy-makers in government ministries, national HIV programmes, civil society (including youth-led and youthserving organizations), members of the Joint UN Team on AIDS, donors, young women and young men, and other partners working at the national and international level to improve the health and well-being of young people. This report provides an overview of the reporting on 18 UNGASS indicators among young people and provides a summary of key findings from the strategic information that countries have reported. Strategic information specific to young people from this report intends to guide policies and programmes with a vision for an AIDS-free generation.
