it is important that basic facts about <strong>HIV</strong>/<strong>AIDS</strong> are internalized and appreciated by all<br />
readers. Facilitators and practitioners need to learn the basic facts and issues that are<br />

prologue presents some basic facts about <strong>HIV</strong>/<strong>AIDS</strong> that are deemed important for all<br />

A glimpse at the prologue:<br />
