The 10-volume "Health Facts" series is intended to supplement health education curricula and provide a handy reference for individuals who would like additional background information on particular health topics. The emphasis is placed on topics and examples relevant to youth of middle and high school age. The five sections in this book provide teachers with basic information about: sexually transmitted disease (STD), also called venereal disease or VD; the history of the STD problem; many of the diseases that are known to be spread through sexual activity, including Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS); bacterial, fungal, and viral STD; and educational, behavioral, and societal control measures that can reduce the spread of sexually transmitted disease among America's youth. An easy to read reference format offers clear, concise data intended to familiarize educators with the most important facts about the issues and concerns. A glossary, a list of resources, and 18 references complete the volume. (LL)
