Since the advent of HIV/AIDS, over 30 years ago, individuals, organisations and governments have come up with various interventions to curb the epidemic, but the epidemic still remains. HIV/AIDS mainstreaming has been one key intervention. The term mainstreaming has, however, remained poorly understood by many. This book presents a systematic way of addressing HIV and AIDS in development organisations and simplifies the meaning of HIV/AIDS mainstreaming. It spells out how to address HIV/AIDS internal mainstreaming in a cost effective way, provides a framework for formulating HIV/AIDS workplace policies and provides practicle examples of what it takes to successfully mainstream HIV/AIDS in an organisation using limited resources. The book gives a simple, systematic and sustainable approach which organisations can adapt and become competent in mainstreaming HIV/AIDS. The book is essential for organisational survival and sustainable organisational effectiveness in times of AIDS. It is relevant for both senior and mid-level managers, development workers, policy- makers, students of development studies and extension workers.
