The briefs are intended as a resource for policymakers in Member States of the Association of Southeast Asian Nations (ASEAN), as well as planners, programme managers, health professionals, service providers, civil society organizations, including key population networks, women’s rights organizations, and others who are advocating for the needs and rights of key affected women and girls. It is hoped that key affected women and girls in each country will be able to use the country briefs to advocate on their own behalf, as well as in partnership with women’s rights groups, key population networks and human rights advocates for the information and services to which they are entitled under international health and human rights standards.
