In the past five years, knowledge and understanding of AIDS have grown exponentially, and the lexicon of related terms has increased significantly. Many of the terms and explanations that were current just a couple of years ago are obsolete or outdated. Similarly, statistics tracking AIDS have also changed dramatically in recent years, drastically altering the opinions held by epidemiologists, social scientists, research scientists, pharmaceutical companies, politicians, doctors, and activists in regard to prevention, treatment, and containment of the disease. New topics and issues are regularly introduced to the international dialog on HIV/AIDS, and The Encyclopedia of HIV and AIDS, Second Edition is a thoroughly revised and expanded volume filled with current information. It covers new and emerging topics and presents recent, accurate statistical information. Originally published as The AIDS Dictionary, this new edition contains more than 3,000 entries covering the basic biological, medical, financial, legal, political, and social issues and terms associated with HIV and AIDS. Entries explain symptoms and treatments, opportunistic infections, prevention strategies, and much more. Appendixes include HIV/AIDS associations, education centers, clinical trials, hotlines, publications, and additional material.Watstein, Sarah is the author of 'Encyclopedia of HIV and AIDS', published 2003 under ISBN 9780816048083 and ISBN 0816048088.
