Introduction: Herpes Simplex Virus type 2 (HSV-2)  is a highly prevalent sexually transmitted infection (STI) The prevalence of HSV-2 infection is increasing in many populations and geographic areas . Herpes simplex virus type 2 (HSV-2) is the cause of most genital herpes and is almost always sexually transmitted. Most HSV-2 infections are consequently expected to occur after the onset of sexua...

Experimental, clinical, and epidemiological evidence strongly suggests that genital Human Papillomaviruses (HPVs) are predominantly sexually transmitted. Epidemiological studies in virginal and HPV-negative women clearly indicate that sexual intercourse is virtually a necessary step for acquiring HPV. As with any other sexually transmitted disease (STD) men are implicated in the epidemiological...

Since 2000, the U.S. Preventive Services Task Force (USPSTF) has issued eight clinical recommendation statements on screening for sexually transmitted infections. This article, written on behalf of the USPSTF, is an overview of these recommendations. The USPSTF recommends that women at increased risk of infection be screened for chlamydia, gonorrhea, human immunodeficiency virus, and syphilis. ...

Adolescent sexuality is a relevant public health issue, as it affects risk to contract HIV and other sexually transmitted infections. The assessment of prevalence of sexual intercourse among adolescents may guide policies and programmes aimed at reducing the transmission of sexually transmitted infections among this age group. Using data from the Thailand Global School-Based Student Health Surv...

Sexuality is more than reproduction, it is an intrinsic part of each of us, is how we develop and relate with others and with the environment of the society to which we belong. Adolescence is a period with special vulnerability for the development of risky behaviors. In Chile, a progressive decrease in the age of sexual activity onset is observed, particularly in lower socioeconomic strata. The...

Evidence shared at the New Delhi meeting revealed some striking similarities in experiences across settings. For example, compared to young women of similar age who did not experience sexual coercion, females who experienced coercion are more likely to experience subsequent incidents of forced sex, as well as (consensual) sexual risktaking behaviours including multiple sexual partners and non-u...

OBJECTIVE To compare HIV-related sexual risk behavior among temporary rural to urban migrants and non-migrants and to explore the role of migration in HIV transmission in a rural area of Ethiopia. METHODS A cross-sectional comparative study was conducted in Bure Woreda, West Gojam, Amhara Region, Ethiopia. A total of 1,310 male subjects (655 rural to urban migrants and 655 non-migrants) were ...

This chapter provides an overview of the epidemiology of human papillomavirus (HPV) infection, with a focus on the dynamics of sexual transmission. We explore concepts related to the spread of sexually transmitted infections, including population prevalence, duration of infectivity, patterns of sexual contacts, and transmissibility, including modifiers of susceptibility and infectivity. HPV pre...

Increases in sexually transmitted diseases (STDs) among men who have sex with men (MSM) have coincided with recent increases in sexual risk behaviors across the United States and Europe. The identification of same-sex sexual risk behavior in men and the subsequent risk for certain bacterial and viral infections requires competency in taking a sexual history. Recent advances in the diagnosis and...

Novel coronavirus disease of 2019 (COVID-19) has impacted health care in general and disrupted our routines. Health services were mostly directed towards the emergency response containment measures to halt virus spreading have been applied worldwide. It also indirectly transmission other infections, including sexually transmitted infections (STI). For STI, physical distancing potential decrease...
