prevalence and correlates of herpes simplex virus type 2 infection: evaluation of behavioural risk factors.	to examine the prevalence and correlates of infection with herpes simplex virus type 2 (hsv-2) among sexually transmitted disease (std) clinic attenders, we studied the prevalence of antibodies to hsv-2 and their association with risk behaviour.	1998	9563706
strong decline in herpes simplex virus antibodies over time among young homosexual men is associated with changing sexual behavior.	the objective of this study was to evaluate whether the change in sexual behavior among homosexual men observed after the start of the acquired immunodeficiency syndrome epidemic resulted in a change in herpes simplex virus (hsv) seroprevalence in this group over time. in a cross-sectional study, the prevalence of herpesvirus types 1 (hsv1) and 2 (hsv2) was determined at study entry in 1984-1985 and 1995-1997 among 532 young (aged < or = 30 years) homosexual men participating in the amsterdam co ...	2000	11032162
diagnosing genital ulcer disease in a clinic for sexually transmitted diseases in amsterdam, the netherlands.	the most common etiologic agents of genital ulcer disease (gud) are herpes simplex virus type 1 (hsv-1), hsv-2, treponema pallidum, and haemophilus ducreyi. in an outpatient clinic for sexually transmitted diseases in amsterdam, the netherlands, specimens from 372 patients with gud were collected from february to november 1996. sera were collected at the time of the symptoms and, for most patients, also during follow-up visits. swabs in viral transport medium were used for hsv culture and for de ...	2001	11158114
seroprevalences of herpes simplex virus type 1 and type 2 among pregnant women in the netherlands.	in the netherlands 73% of cases of neonatal herpes are caused by herpes simplex virus type 1 (hsv-1), whereas in the united states a majority are caused by hsv type 2 (hsv-2). goal to understand this difference we undertook a seroepidemiological study on the prevalence of hsv-1 and hsv-2 among pregnant women.	2002	12438909
rise in seroprevalence of herpes simplex virus type 1 among highly sexual active homosexual men and an increasing association between herpes simplex virus type 2 and hiv over time (1984-2003).	herpes simplex virus type 1 and type 2 (hsv-1 and hsv-2) are both highly prevalent. the rate of genital hsv-1 transmission is reportedly increasing over time. hsv-2 is considered to be an important risk factor for hiv transmission. we therefore studied changes in the hsv-1 and hsv-2 prevalence in a large cohort of men who have sex with men (msm) over a 20-year time period.	2007	17929177
ethnic differences in hsv1 and hsv2 seroprevalence in amsterdam, the netherlands.	herpes simplex virus type 1 (hsv1) and 2 (hsv2) infection can lead to significant morbidity, and hsv2 is considered a risk factor for hiv transmission. the majority of hsv-infected people are asymptomatic and unaware of their infection. we aimed to determine the hsv1 and hsv2 prevalence among various ethnic groups in a large urban area in the netherlands. in 2004, serum samples from a population-based serum repository of 1,325 people over 18 years living in amsterdam were tested for hsv1 and hsv ...	2008	18761942
