This guide defines the principles of adaptation promoted by WHO and outlines a generic framework for the process of adapting HIV guidelines for national programmes. It does not provide full guidance on developing an operational plan, but does offer suggestions for strategic planning (or re-planning) for the national response to HIV. In addition, the document contains an annex of case studies. These are country examples that highlight specific elements of the adaptation and implementation of the five recently revised HIV guidelines.   Download this document.
