More than 30 different organisms cause infection and disease when transmitted by venereal contact. Sexually transmitted diseases (STDs) represent 87 percent of all reported infections.

This encyclopedia provides a wealth of information on STDs and associated topics, including care centers and departments, legal issues, and related associations and organizations. Coverage of the diseases includes such information as history, causes and origins; risk factors; diagnostic tests; considerations in pregnancy; and much more.

The work concludes with a wide selection of resources. Books, journals, support groups, hotlines, organizations, and Internet sites are listed, along with sources for information on topics such as low cost prescription drug programs, social security disability, health insurance, and clinical trials.
