Gr 7 Up-This eye-opening account explains the complicated science behind the re-emergence of almost-extinct diseases such as malaria, smallpox, and tuberculosis. Kowalski supplies evidence that many existing infections and diseases are becoming resistant to current treatments and provides examples of new, lethal outbreaks and epidemics emerging in this era of modern medicine. It is disheartening to note that promising new drugs have only a short therapeutic lifespan before they become essentially obsolete. This is especially true with HIV drug preparations because of the mutating nature of the virus. In addition, improperly prescribed medicines and the misuse of drugs in human beings, especially the overuse of antibiotics, and growth promoters in livestock and poultry, create an ideal environment and exert selective pressures for more resistant or for even more harmful microbes to flourish. This title is a good choice for young adults because it explains what they can do to prevent or minimize infection. The up-to-date text is complemented by full-color photos, diagrams, and informational sidebars.-Caroline Geck, Kean University, Union, NJ Copyright 2006 Reed Business Information.
