International aspects of the AIDS/HIV epidemic

Abstract

This review provides the reader with pertinent information on the epidemiology, prevention, and new technologies of the ongoing HIV pandemic. These aspects are key to international policy discussions surrounding the public health response to the international spread of HIV. Our understanding of the impact of AIDS on other diseases is evolving, as is our insight into the demographic and economic effects of the epidemic on the global community. Observations on the success of certain prevention strategies allow rational allocation of resources in newly affected epidemic areas. Information on the origin and nature of HIV transmission exemplifies the phenomenon of global emerging infections. As world populations are brought closer together through transportation, communication, trade, and commerce, insight into emerging infections of epidemic potential becomes increasingly important to the practitioner of public health. Although important, legal and social aspects of the epidemic will not be emphasized here. The epidemics of HIV/AIDS in the United States and Europe are not reviewed here. The global pandemic has recently been described in an overview in this publication to which the reader is also referred.
