During the two years since the publication of the first edition of this book, the global spread of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has continued. HIV was estimated by the World Health Organization (WHO) in 1993 to have at least 13 million individuals worldwide, with 1 million infected infected in the United States. HIV/AIDS in the United States has become the leading cause of death among men 25 to 44 years of age and the fifth leading cause of death among women of the same age group. Prevention of HIV infection remains a global challenge. Testing for HIV is the cornerstone for surveillance and prevention programs and for the provision of appropriate medical care for those who are infected. Such testing is equally essential to the search for effective antivirus drugs and vaccines. This second edition of AIDS Testing incorporates the most current thinking on test methodology and interpretation, some of which has changed considerably over the past two years. This edition also has been expanded to include a section consisting of six chapters on test applica tions and a section consisting of four chapters on management issues. This edition, like the first, describes in clear terms all the complex ele ments of testing, including applications, scientific principles, quality assurance, safety, and medical, ethical, and legal considerations."

In October, 1987, smallpox became the first disease of humans to have been deliberately eradicated. Since then, global eradication campaigns against dracunculiasis (Guinea worm disease) and poliomyelitis have nearly reached their goals, and initial steps have been taken to stimulate similar programs to eradicate lymphatic filariasis and measles. Other successful efforts are expected to follow these. In 1993, an International Task Force for Disease Eradication evaluated over 80 potential candidate diseases and made recommendations. However, little has been done to develop the science of eradication systematically. This book reports the findings of a multidisciplinary workshop on the eradication of infectious diseases. It reviews the history of eradication efforts and lessons from previous campaigns and distinguishes among eradication, elimination, and control programs and extinction of an etiologic agent. It addresses a wide range of related issues, including biological and socio-political criteria for eradication, costs and benefits of eradication campaigns, opportunities for strengthening primary health care in the course of eradication efforts, and other aspects of planning and implementing eradication programs. Finally, it stresses the importance of global mechanisms for formulating and implementing such programs. Goal of this Dahlem Workshop: to identify the biological/epidemiological, cost/benefit, and societal/political criteria for the eradication of infectious diseases.

Given the continuing high level of concern among health professionals and the general public about issues related to AIDS, this volume on testing for AIDS and related viruses is extremely timely. The book has been written by experts in the area of AIDS testing, many of whom are at the Centers for Disease Control. The book includes several chapters which compare the different laboratory tests available for detecting the AIDS virus (HIV). It also addresses such topics as ethical considerations in AIDS testing, HIV infection in children, testing for other human viruses related to HIV, safety practices in HIV-testing laboratories, and managing occupational exposure to HIV. The book is intended for public health officials involved in HIV testing, hospital administrators and clinical laboratory directors responsible for setting up HIV testing programs, and physicians concerned with testing for AIDS.
