This review was requested by the Department of Health of the Philippines and the Philippine National AIDS Council (PNAC) and conducted with the support of the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS). An external review of the health sector response to HIV and Sexually Transmitted Infections in the Philippines was conducted by a team of national and external reviewers (Team B) at the request of the Department of Health. A broader review of the multi-sectoral response to HIV was conducted simultaneously in September and October 2013 by another team of consultants (Team A) under the auspices of the Philippine National AIDS Council (PNAC). The aim of this combined review was to assess progress and constraints at the midterm of implementation of the Fifth AIDS Medium-Term Plan 2011-2016 (AMTP5). AMTP5 is structured around five strategic objectives, two of which are directly relevant to and managed by the health sector, namely prevention, and care and treatment.
