Sexually transmitted diseases (STDs) are now the most common group of identifiable infectious diseases in many countries, especially among those ages 15-50 and in infants. Their control is important considering the high incidence of acute infections, complications and sequelae, their socioeconomic impact, and their role in increasing transmission of the human immunodeficiency virus (HIV). THe worldwide incidence of major bacterial and viral STDs is estimated to be over 125 million cases yearly. STDs are hyperendemic in many developing countries. However, in industrialized countries, the bacterial STDs such as syphilis, gonorrhea, chancroid declined from their peak during WW II until the late 1950s, increased during the 1960s and early 1970s, and have again decreased since that time. In the industrialized world, diseases due to Chlamydia trachomatis, genital herpes virus, human papillomaviruses, and HIV are now more significant than the classical bacterial ones; both groups remain major health problems in most developing countries. Infection rates are similar in both men and women, but women and infants bear the major burden of complications and serious sequelae. Infertility and ectopic pregnancy are often a result of pelvic inflammatory disease and are preventable. STDs in pregnant women can result in prematurity, stillbirth, and neonatal infections. In many areas, 1-5% of newborns are at risk of gonococcal ophthalmia neonatorum, a disease that blinds and congenital syphilis causes up to 25% of perinatal mortality. Genital and anal cancers (especially cervical cancer) are associated with viral STDs (genital human papillomavirus and herpes virus infections). Urethral stricture and infertility are frequent sequelae in men. (author's modified)
