Sexually transmitted infections in developing countries : current concepts and strategies on improving STI prevention, treatment, and control (Inglês)

The global burden of sexually-transmitted infections (STIs) to health and development is often overlooked as a public health priority. The majority of STIs worldwide are caused by eight infections: syphilis, gonorrhea, chlamydia, trichomoniasis, genital herpes, hepatitis B virus (HBV), and human papillomavirus (HPV). These infections, often silent and without symptoms, can result in serious or fatal health consequences. Cervical cancer, caused by HPV, is the largest single cause of years of life lost to cancer in the developing world and, because it affects women in their most productive years, has a devastating effect on the well-being of families. Syphilis among pregnant women still results in up to 1.5 million perinatal deaths each year. Damage to the fallopian tubes from gonorrhea and chlamydia can lead to infertility, as well as tubal pregnancy, an important cause of maternal death in developing countries. Hepatitis B, most frequently transmitted from mother-to-child in endemic areas, can result in chronic infection, liver cancer and liver failure. Genital herpes and other genital ulcer diseases increase risk of HIV transmission. STIs are among the world's most common diseases, with an annual incidence exceeded only by diarrheal diseases, malaria, and lower respiratory infections. The burden on the health care system and healthcare expenditure is great. STIs, even without including HIV, are consistently among the most common conditions leading to health care visits regardless of national resources. Due to their high prevalence, particularly in developing country settings, STIs result in substantial productivity losses for individuals and communities, particularly where the majority of the population is under 40 years of age. In developing country settings, STIs are among the leading causes of disability adjusted life years (DALYs) lost for women of reproductive age, exceeded only by maternal causes and HIV. This technical note was developed to provide World Bank technical staff a background in STI burden, economic costs, evidenced-based STI programmatic interventions. New research findings and future directions are also discussed, such as new point-of-care diagnostics, herpes simplex virus (HSV) treatment to prevent HIV and male circumcision.
