This reference answers consumer-type questions about common contagious diseases (e.g., HIV/AIDS, hepatitis, lice) as well as emerging diseases such as Severe Acute Respiratory Syndrome (SARS). Following an overview of how germs cause different types of diseases and how to protect against them, concerns about antibiotic resistance and vaccines are addressed in 70 article-based chapters. Features include a statistical summary; discussion of the possible relationship between infectious agents, vaccines, and certain chronic diseases (e.g., chronic fatigue syndrome, inflammatory bowel disease); a glossary; and resources (including the National Vaccine Injury Compensation Program).
