          Abstract

          Resumen Se hace un recorrido por las causas, estimaciones, contagios y tendencias de las enfermedades de transmisión sexual en el siglo XXI. Se incide en que si se mantienen los estilos sociales, demográficas y migratorias, la población expuesta a infecciones de transmisión sexual seguirá aumentando espectacularmente. La carga de morbilidad es particularmente pesada en el mundo en desarrollo, pero también en los países industrializados cabe prever un aumento de la carga de enfermedad debido a la prevalencia de infecciones víricas incurables, a las tendencias en el comportamiento sexual y al incremento de los viajes.

          Abstract A tour of the causes, estimates, infections and trends of sexually transmitted diseases in the 21st century is made. It is stressed that if social, demographic and migratory styles are maintained, the population exposed to sexually transmitted infections will continue to increase dramatically. The burden of disease is particularly heavy in the developing world, but also in industrialized countries the burden of disease can be expected to increase due to the prevalence of incurable viral infections, trends in sexual behavior and increased travel.

          Sexually transmitted infections among US women and men: prevalence and incidence estimates, 2008.

          Most sexually active people will be infected with a sexually transmitted infection (STI) at some point in their lives. The number of STIs in the United States was previously estimated in 2000. We updated previous estimates to reflect the number of STIs for calendar year 2008. We reviewed available data and literature and conservatively estimated incident and prevalent infections nationally for 8 common STIs: chlamydia, gonorrhea, syphilis, herpes, human papillomavirus, hepatitis B, HIV, and trichomoniasis. Where available, data from nationally representative surveys such as the National Health and Nutrition Examination Survey were used to provide national estimates of STI prevalence or incidence. The strength of each estimate was rated good, fair, or poor, according to the quality of the evidence. In 2008, there were an estimated 110 million prevalent STIs among women and men in the United States. Of these, more than 20% of infections (22.1 million) were among women and men aged 15 to 24 years. Approximately 19.7 million incident infections occurred in the United States in 2008; nearly 50% (9.8 million) were acquired by young women and men aged 15 to 24 years. Human papillomavirus infections, many of which are asymptomatic and do not cause disease, accounted for most of both prevalent and incident infections. Sexually transmitted infections are common in the United States, with a disproportionate burden among young adolescents and adults. Public health efforts to address STIs should focus on prevention among at-risk populations to reduce the number and impact of STIs.

            Global Estimates of the Prevalence and Incidence of Four Curable Sexually Transmitted Infections in 2012 Based on Systematic Review and Global Reporting

            Background Quantifying sexually transmitted infection (STI) prevalence and incidence is important for planning interventions and advocating for resources. The World Health Organization (WHO) periodically estimates global and regional prevalence and incidence of four curable STIs: chlamydia, gonorrhoea, trichomoniasis and syphilis. Methods and Findings WHO’s 2012 estimates were based upon literature reviews of prevalence data from 2005 through 2012 among general populations for genitourinary infection with chlamydia, gonorrhoea, and trichomoniasis, and nationally reported data on syphilis seroprevalence among antenatal care attendees. Data were standardized for laboratory test type, geography, age, and high risk subpopulations, and combined using a Bayesian meta-analytic approach. Regional incidence estimates were generated from prevalence estimates by adjusting for average duration of infection. In 2012, among women aged 15–49 years, the estimated global prevalence of chlamydia was 4.2% (95% uncertainty interval (UI): 3.7–4.7%), gonorrhoea 0.8% (0.6–1.0%), trichomoniasis 5.0% (4.0–6.4%), and syphilis 0.5% (0.4–0.6%); among men, estimated chlamydia prevalence was 2.7% (2.0–3.6%), gonorrhoea 0.6% (0.4–0.9%), trichomoniasis 0.6% (0.4–0.8%), and syphilis 0.48% (0.3–0.7%). These figures correspond to an estimated 131 million new cases of chlamydia (100–166 million), 78 million of gonorrhoea (53–110 million), 143 million of trichomoniasis (98–202 million), and 6 million of syphilis (4–8 million). Prevalence and incidence estimates varied by region and sex. Conclusions Estimates of the global prevalence and incidence of chlamydia, gonorrhoea, trichomoniasis, and syphilis in adult women and men remain high, with nearly one million new infections with curable STI each day. The estimates highlight the urgent need for the public health community to ensure that well-recognized effective interventions for STI prevention, screening, diagnosis, and treatment are made more widely available. Improved estimation methods are needed to allow use of more varied data and generation of estimates at the national level.

              The estimated direct medical cost of selected sexually transmitted infections in the United States, 2008.

              Millions of cases of sexually transmitted infections (STIs) occur in the United States each year, resulting in substantial medical costs to the nation. Previous estimates of the total direct cost of STIs are quite dated. We present updated direct medical cost estimates of STIs in the United States. We assembled recent (i.e., 2002-2011) cost estimates to determine the lifetime cost per case of 8 major STIs (chlamydia, gonorrhea, hepatitis B virus, human immunodeficiency virus (HIV), human papillomavirus, genital herpes simplex virus type 2, trichomoniasis and syphilis). The total direct cost for each STI was computed as the product of the number of new or newly diagnosed cases in 2008 and the estimated discounted lifetime cost per case. All costs were adjusted to 2010 US dollars. Results indicated that the total lifetime direct medical cost of the 19.7 million cases of STIs that occurred among persons of all ages in 2008 in the United States was $15.6 (range, $11.0-$20.6) billion. Total costs were as follows: chlamydia ($516.7 [$258.3-$775.0] million), gonorrhea ($162.1 [$81.1-$243.2] million), hepatitis B virus ($50.7 [$41.3-$55.6] million), HIV ($12.6 [$9.5-$15.7] billion), human papillomavirus ($1.7 [$0.8-$2.9] billion), herpes simplex virus type 2 ($540.7 [$270.3-$811.0] million), syphilis ($39.3 [$19.6-$58.9] million), and trichomoniasis ($24.0 [$12.0-$36.0] million). Costs associated with HIV infection accounted for more than 81% of the total cost. Among the nonviral STIs, chlamydia was the most costly infection. Sexually transmitted infections continue to impose a substantial cost burden on the payers of medical care in the United States. The burden of STIs would be even greater in the absence of STI prevention and control efforts.
