'Building Blocks: Asia is a series of practical briefing notes to assist policy-makers, non-governmental organisations (NGOs), community-based organisations (CBOs), local government and communities to respond to the needs of children affected by HIV and AIDS in Asia. There are seven briefing notes, comprising six topics and an overview : Health and nutrition; Livelihoods and economic strengthening; Education and training; Care and psychosocial support; and Social inclusion Protection. Each briefing note introduces issues and provides principles and strategies for guiding the response, while offering examples of best practice from programme experience. The briefing notes are all divided into three sections: 1. Introduction: This section explains the topic and how it relates to children and families affected by HIV and AIDS; 2. Issues: An outline of the impact of HIV/AIDS on children; 3. Principles and strategies: Guidelines and possible ways of taking action to strengthen support for orphans and vulnerable children. The strategies reflect international good practice and the experience of people working with orphans and vulnerable children in Asia.
