This book is a practical guide in understanding how to prevent HIV transmission, to recognize risk behaviors, and to add something else to their repertoires. It aims to empower clinicians and provide a sense of security and competence with the recognition and understanding of some of the psychiatric illnesses that complicate and perpetuate the HIV pandemic that continue to persist throughout every area of the world despite the magnitude of the progress that has transformed the illness from a rapidly fatal to chronic illness that is no longer life-limiting. Missing in most of the literature on HIV is the subtle, and sometimes not so subtle, contribution of psychiatric symptoms, psychiatric illness, and risk behaviors that drive the pandemic and serve as catalysts for new infections.
