Covers all aspects (historical, epidemiological, diagnostic, clinical, preventative, public health and medico-legal) of STIs in complete detail with a special emphasis on STIs in special groups―migrants, homosexuals, and sexually abused. Covers basic and laboratory sciences extensively to blend with the basics required by the clinician for proper understanding of the disease process. Clinical photographs, illustrations, photographs of specimens and cultures, histopathology, flow charts and line diagrams are given extensively throughout the text to make relevant clinical situation self-explanatory. Has very useful and practical information for even the clinician in the periphery, where the investigative component is either non-existent or very basic and many new drugs are not available or unaffordable. Management of HIV in adults and children in resource-poor countries has been covered extensively along with syndromic management of STIs. This enables a physician to choose from approaches in a particular situation depending upon the available means―laboratory or therapeutic. Covers sexual dysfunction in both men and women and the basics of human sexual behavior and sexual health. Section Editors and Contributors from all continents of the world have made this a truly global reference book. It is a useful reference text for epidemiologists, public health experts, clinicians, microbiologists, health workers, social organizations and counselors working in the field of STIs, sexual health, and HIV.
