Nelson Mandela Hsrc Study Of Hiv Aids PDF Download

Over 20 years ago Acquired Immune Deficiency Syndrome (AIDS) was first documented and more than 15 years ago HIV was first identified as a causative agent for AIDS. Since then, the epidemic has spread throughout the world, but at an uneven pace. It is estimated that more than 60 million people worldwide have lived with HIV/AIDS since the beginning of the epidemic and 20 million of these have died (UNAIDS 2002). HIV/AIDS now affects every country in the world. Despite advances made in knowledge about HIV prevention, the disease continues to spread. Globally, sub-Saharan Africa is the most severely affected, with the Southern African Development Community (SADC) being home to half of the estimated 24 million people living with HIV/AIDS in this region (UNAIDS 2000). Country level estimates of HIV infection are usually based on surveys of women attending antenatal clinics. In South Africa over the past decade, this has been the primary means of monitoring the spread of HIV. Antenatal surveillance systems provide countries with a low-cost tool for regularly monitoring key aspects of the HIV epidemic. For example, the data can be used to track the epidemic in different parts of a country or among a specific age cohort. The antenatal survey's major usefulness is to track trends of HIV infections over time.
