This field guide is designed to assist in responding to HIV/AIDS as an integral part of health activities. It provides guidance and decision making tools to help decide what to do amongst specific populations in a given context, and guidance on how to integrate HIV/AIDS into core health activities. Annexe 1 contains a series of Action Guides that summarise information on key topics and options for action. These need to be read in conjunction with more detailed technical resources, references to which are provided in each Action Guide. The CD includes expanded Action Guides and a case study. The content of this guide is aimed primarily at health staff, but it is also relevant for management staff.
