Abstract
Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) infections continue to be among the most common and unrecognized sexually transmitted infections in the world. Although treatable, HSV-1 and HSV-2 infections remain incurable. Hence, there is interest in the development of a vaccine to prevent genital herpes. As part of a multicentre, randomized, placebo-controlled trial to test such a vaccine, healthy women 18-30 years were enrolled as volunteers in several Canadian centres between 2005 and 2007. This study reports the seroprevalence of HSV-1 and HSV-2 antibodies in this group. A total of 2694 adult female volunteers in Canada with no known history of herpes simplex were screened for HSV antibodies using Western blot assay (the gold standard for diagnosis of HSV) for potential participation in a randomized, double-blind efficacy field trial of a herpes simplex vaccine. This trial provides a unique opportunity to examine the prevalence of antibodies to HSV-1 and of antibodies to HSV-2 in women with no known history of herpes simplex infection. The prevalence of antibodies to HSV-1 and to HSV-2 is compared with that found in previous Canadian studies that focused on a more general population. The overall seroprevalence of antibody to HSV-1 was 43%; that of HSV-2 was 2.5% and seropositivity to both was 2%. The prevalence of antibody to both HSV-1 and to HSV-2 increased with age. Seronegativity to both HSV-1 and HSV-2 was 56% in participating centres with populations under 250,000 and 46% in participating centres with populations over 250,000. Significant racial differences in seropositivity to HSV-1 and to HSV-2 were noted. The likelihood of participants being seropositive to HSV-1 and to HSV-2 was found to increase with age and to positively correlate with the population of the city in which they resided. Hypotheses are proposed to account for differences in racial seropositivity to HSV-1 and to HSV-2.

Abstract
The epidemiology of genital herpes is changing with evidence to suggest an increasing incidence of herpes simplex virus type 1 (HSV-1) infections. The results of 6529 HSV genital cultures taken between April 1998 and December 2001 were reviewed. overall, HSV-1 was recovered more often than HSV-2; 1213 versus 1045. This trend was particularly striking in young women 30 years of age or less, in whom 70.8% of isolates were HSV-1. In men of the same age range, 45% of isolates were HSV-1. The proportion of women with HSV-1 declined from 73.7% in those younger than 31 years of age to 4.5% in those older than 60 years of age.These observations have important implications. The decline in the relative proportion of HSV-1 isolates from young adults may be the result of changing sexual practices, changing susceptibility or increased exposure to HSV-1 during vaginal intercourse. In this setting HSV-2 vaccines may be less likely to produce the desired reduction in the overall prevalence of genital herpes infections.

Abstract
BACKGROUND Changing social conditions and life-styles in Sweden may have affected the spread of varicella-zoster virus (VZV), herpes simplex virus (HSV), cytomegalovirus (CMV), and Epstein-Barr virus (EBV). OBJECTIVES To study possible changes over 30 years in prevalence of antibodies against VZV, HSV, CMV, and EBV in Swedish children, using modern serological methods. STUDY DESIGN Serum samples from 819 Swedish children who were 9-12 years old in 1967-1968, in 1977-1978 (two cohorts), and in 1997, respectively, were examined. IgG antibodies against VZV, HSV, and CMV were measured by well validated enzyme-linked immunosorbent assays and against EBV by indirect immunoflourescense. RESULTS The seropositivity for VZV for 9-12 years old children was 50% in 1967-1968, 74-82% in 1977-1978, and 98% in 1997. The corresponding figures were 31%, 53%, 50%, and 58% for CMV, 35%, 35%, 32%, and 38% for HSV, and 64% in 1967-1968 and in 1977-1978 (both cohorts), and 62% in 1997 for EBV. CONCLUSIONS The seroprevalence for VZV increased significantly from 1967-1968 to 1997, and there was also a significant but smaller increase in the CMV seroprevalence, while seroprevalence to HSV and EBV remained relatively stable.

Abstract
UNLABELLED DESIGN/ SETTING: A cohort study of 1037 people born in Dunedin, New Zealand, in 1972 or 1973. PARTICIPANTS At assessment at age 32 years, 884 participants (432 women and 452 men; 87.1% of the surviving cohort) provided both sera and information on sexual behaviour. MAIN OUTCOME MEASURES The proportion of participants with antibodies to HSV-2 infection at ages 26 and 32 years was measured, and the incidence rates from first coitus to age 26 years and from age 26 to 32 years calculated, adjusting for the number of sexual partners and same-sex contact in these age periods. RESULTS At age 32 years, 14.6% of men and 22.5% of women had antibodies to HSV-2. The incidence rates for men and women from first coitus to age 26 years were, respectively, 6.5 and 14.3 per 1000 person-years. The incidence rates for men and women from age 26-32 years, respectively, were 14.3 and 15.8 per 1000 person-years. When adjusted for sexual behaviour, the incidence rate ratio, comparing the older with the younger age periods, was 2.9 (95% confidence interval (CI) 1.7 to 4.9) for men and 2.0 (1.2 to 3.4) for women. The adjusted incidence rate ratio when comparing women to men from first coitus to age 26 years was 2.5 (1.6 to 4.0), and from age 26-32 years was 1.3 (0.78 to 2.2). A test for interaction indicated that men and women had different patterns of incidence over time (p = 0.039). CONCLUSION In the general population, the risk of acquiring HSV-2 infection seems to increase with age at least to the early 30s, and differences in risk of acquisition for women compared with men become less with age. Health promotion and treatment to control HSV-2 infection should be aimed at all ages, not just at the young.

Abstract
OBJECTIVE The objective of this study was to improve the knowledge on the epidemiology of herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) in Italy. GOAL The goal of this study was to study the seroincidence and seroprevalence of HSV-1 and HSV-2 infections among Italian adolescents. STUDY We conducted a retrospective longitudinal study among 345 Italian adolescents tested for anti-HSV-1 and anti-HSV-2 on samples collected at 11 and 17 years of age. RESULTS At 11 years of age, the HSV-1 prevalence was 51.6% and the HSV-2 prevalence was 2.6%; when 17 years old, these rates increased to 61.4% and 4.9%, respectively. The HSV-1 incidence was 1.6 per 100 person-years and was higher among females. The HSV-2 incidence was 0.4 per 100 person-years with no gender differences. CONCLUSION HSV-1 is apparently widespread among Italian adolescents, whereas HSV-2 is limited. These data are of paramount importance when considering that HSV-1 can cause genital herpes and that HSV-2 plays a role in HIV transmission.

Abstract
Herpes simplex virus (HSV) infections occur commonly among adolescents. Most HSV-2 infections are genital, but genital herpes can be caused by either HSV-1 or HSV-2. Weighted means were calculated based on published seroprevalence data on adolescents from the United States and found HSV-1 rates of 53.1 percent for adolescent males and 49.4 percent for adolescent females. The weighted means for HSV-2 was 15 percent for adolescent females and 12 percent for adolescent males. Most individuals who are infected with HSV-2 are unaware of their infection. Healthcare providers of adolescents should consider genital herpes even when an adolescent presents with nonspecific genital symptoms. In this article, we review current recommendations for diagnosis and management and review the psychological sequelae that can be associated with having genital herpes. Finally, we discuss biomedical interventions that are being developed to help reduce the epidemic of HSV and the challenges that these interventions face with regard to implementation.

Abstract
OBJECTIVES To describe the seroepidemiology of herpes simplex virus (HSV) types 1 and 2 in the general populations of eight European countries to better understand recent reported changes in disease epidemiology. METHODS Belgium, Bulgaria, Czech Republic, England and Wales, Finland, Germany, Netherlands, and Slovenia conducted national cross sectional serological surveys for HSV-1 and HSV-2 between 1989 and 2000. Survey sizes ranged from 3000 to 7166 sera. External quality control was ensured through reference panel testing. RESULTS Large intercountry and intracountry differences in HSV-1 and HSV-2 seroprevalence were observed. Age standardised HSV-1 seroprevalence ranged from 52% in Finland, to 57% in the Netherlands, 67% in Belgium, 81% in Czech Republic, and 84% in Bulgaria. Age standardised (>12 years) HSV-2 seroprevalence ranged from 24% in Bulgaria, to 14% in Germany, 13% in Finland, 11% in Belgium, 9% in Netherlands, 6% in Czech Republic, and 4% in England and Wales. In all countries, probability of seropositivity for both infections increased with age. A large proportion of teenagers and young adults remain HSV-1 susceptible particularly in northern Europe. Women were significantly more likely to be HSV-2 seropositive in six of seven (p<0.05) countries and HSV-1 seropositive in four of seven (p<0.05) countries, particularly in northern Europe. No significant evidence of a protective role of HSV-1 for HSV-2 infection was found adjusting for age and sex (p<0.05). CONCLUSIONS There is large variation in the seroepidemiology of HSV-1 and HSV-2 across Europe. The observation that a significant proportion of adolescents are now HSV-1 susceptible may have implications for transmission and clinical presentation of HSV-1 and HSV-2.

Abstract
Canine herpesvirus-1 (CHV-1) is presumed to be enzootic in the dog population and is associated with fertility disorders and neonatal mortality. In this study we screened for risk factors affecting CHV-1 antibody titers and investigated the association between antibody titers and reproductive disorders. Therefore, serum from 545 dogs used for reproduction was analysed with an ELISA. Using a forward stepwise procedure and retaining significant risk factors (P<0.05), best fitting multifactorial generalized linear model (glm) procedures were built for males and females. The effect of antibody titers on reproductive disorders was analysed with logistic regression analysis. The association between reproductive disorders and seroprevalence was analysed in chi-square analyses using contingency tables. In both sexes, kennel cough and breeding management were found to have an impact on the CHV-1 antibody titer. Also, the influence of kennel cough on the antibody titer was correlated to the hygienic status of the kennel. In females, age, kennel size and cycle stage had an effect on CHV-1 antibody titers. Furthermore, kennel size and hygiene were found to be correlated. In males, mating experience had an impact on CHV-1 antibody titers. An association was observed between serological status and a history of abortion in bitches. In conclusion, this study suggests CHV-1 antibody titers may be affected by many factors, both on an environmental and host level. Therefore, interpretation of the serological status requires precaution. Furthermore, oronasal and venereal transmission seem to play a role in the spreading of infection.

Abstract
The changing spectrum of herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) infections makes it important to define the seroepidemiology of HSV. The object of this study was to determine the prevalence of HSV-1 and HSV-2 immunoglobulin G antibodies in a young Swedish population by investigating 2106 serum samples from people aged 0-19 y. Sera were tested in HSV type-specific enzyme-linked immunosorbent assays using glycoprotein G-1 (gG-1) and glycoprotein G-2 (gG-2) as antigens. The overall seroprevalence was 31% (95% CI 29-33) for HSV-1 and 0.5% (95% CI 0.2-0.9) for HSV-2. The HSV-1 seroprevalence was higher with increasing age, and significantly higher in the age cohort 15-19 y compared with 1-4-y-olds (37% vs 24%). The HSV-1 infection seemed to be acquired early in life. In the age cohort 1-2 y, the prevalence was over 20%, presumably reflecting an established viral infection. In adolescence the HSV-1 seroprevalence may reflect both oral and sexual transmission. The seroprevalence in the oldest age cohort did not differ significantly from that seen in a Swedish study in which sera were sampled from young girls in the 1970s.

Abstract
Information on age- and sex-specific prevalence of herpes simplex virus (HSV) types 2 and 1 infections is essential to optimize genital herpes control strategies, which increase in importance because accumulating data indicate that HSV-2 infection may increase acquisition and transmission of human immunodeficiency virus. This review summarizes data from peer-reviewed publications of type-specific HSV seroepidemiologic surveys. HSV-2 prevalence is, in general, highest in Africa and the Americas, lower in western and southern Europe than in northern Europe and North America, and lowest in Asia. HSV-2 and -1 prevalence, overall and by age, varies markedly by country, region within country, and population subgroup. Age-specific HSV-2 prevalence is usually higher in women than men and in populations with higher risk sexual behavior. HSV-2 prevalence has increased in the United States but national data from other countries are unavailable. HSV-1 infection is acquired during childhood and adolescence and is markedly more widespread than HSV-2 infection. Further studies are needed in many geographic areas.

Abstract
OBJECTIVE The aim of this study was to assess the association of fetal death with herpes simplex virus type-2 (HSV-2) antibody status during pregnancy: 1. presence of antibodies in first trimester; 2. appearance of antibodies (incident infection); 3. increase in antibody titre; and 4. loss of antibodies. DESIGN Prospective study. POPULATION The source population was a cohort of 35,940 pregnant women in Norway. METHODS Nested case-control study within the cohort. Cases were all women in the study population who experienced a fetal death after the 16th weeks of gestation (n = 281), and controls were 961 randomly selected women with a live born child. MAIN OUTCOME MEASURES HSV-2 antibody status. RESULTS Twenty-nine percent (82/281) of women with a fetal death and 27% (256/961) of the controls had of HSV-2 antibodies present in the first trimester (odds ratio 1.1, 95% CI 0.8-1.5). HSV-2 antibodies appeared in 2% (3/136) of initially seronegative cases and 3% (16/623) of the controls during pregnancy (odds ratio 0.9, 95% CI 0.2-3.0). An increase in HSV-2 antibodies occurred in 4% (2/55) of initially seropositive cases and 7% (16/231) of the controls (odds ratio 0.5, 95% CI 0.1-2.3). Loss of HSV-2 antibodies in initially seropositive women was not associated with fetal death, 42% (23/55) of the cases and 45% (104/231) of the controls seroreverted (odds ratio 0.8, 95% CI 0.5-1.6). Differences in follow up time, age and parity were controlled and did not influence the comparisons between cases and controls. CONCLUSION This study provides no evidence of an association between HSV-2 infection during pregnancy and fetal death.

Abstract
OBJECTIVES To examine changes in the incidence and prevalence of herpes simplex type 2 (HSV-2) infection in a birth cohort of 26 year old New Zealanders in whom seroprevalence had been measured at 3.4% at age 21. METHODS Sera from 869 cohort members were tested using an indirect IgG enzyme linked immunoassay specific to the HSV-2 glycoprotein G. Serological results were compared with detailed sexual histories. RESULTS In all, 96 participants (11%) were seropositive for HSV-2, including at least 56 who seroconverted after their 21st birthday. Among those known to be seronegative at age 21, the annual seroconversion rate was 13.5 cases per 1000 per year, compared with 8.1 cases per 1000 per sexually active year before age 21. New infections were associated with female sex and an early age of first intercourse. The average rate of partner change was lower in the cohort after age 21, and was only modestly increased among those who acquired new HSV-2 infections between ages 21 and 26. CONCLUSIONS HSV-2 seroprevalence has risen sharply in this sexually active cohort, despite a reduction in the overall level of partner change. Increased rates of HSV-2 acquisition after age 21 may be due to a higher prevalence of infection in the pool of potential partners encountered during the third decade of life. Factors related to partner choice may have more influence on the risk of HSV-2 infection than the number of sexual partners alone.

Abstract
Herpes infections are among the most common sexually transmitted diseases and are the most common cause of genital ulcer disease in the United States. This study addresses the changing distribution of herpes simplex virus type 1 (HSV-1) and HSV-2 in patients presenting for evaluation of herpetic infections. Viral culture results from the University of Kentucky Clinical Microbiology Laboratory were reviewed for a 6-year period (1994 through 1999). Data were collected on patient sex, site of culture, and culture result. These data were analyzed statistically to identify yearly trends. Of the 4,498 cultures analyzed, nearly equal proportions of HSV-1 (13.3%) and HSV-2 (12.0%) were detected for an overall culture positivity rate of 25.3%. Approximately two-thirds of all positive cultures were from women. Although HSV-2 remained the predominant type of genital herpes, over the 6-year span of this study, there was a trend toward increasing proportions of HSV-1 genitalis, with 31.8% of male patients and 44.8% of female patients demonstrating HSV-1 genitalis by 1999. The majority of patients with HSV in nongenital sites grew HSV-1. Although there was significant yearly variation, HSV-2 was isolated from only 9.4% of patients with nongenital HSV for the entire 6-year period. This study therefore concludes that HSV-2 remains primarily a genital pathogen, while HSV-1 is taking on an increasingly important role in causing genital ulcer disease in addition to being the primary nongenital HSV.

Abstract
PURPOSE To review the changing epidemiology of herpes simplex disease and correlate it with the epidemiology of ocular herpes simplex disease. METHOD A review of pertinent reports in the world literature about the epidemiology of herpes simplex and specifically about ocular herpes simplex. RESULTS In developed countries, many individuals are reaching adolescence and adulthood without prior herpesvirus infection. Herpes simplex genital infection is increasing at a rapid rate in sexually active adolescents and adults, with about one in six adults now infected in the United States. Similar statistics are confirmatory worldwide in developed countries. Active herpes simplex infection is a risk factor for acquisition of human immunodeficiency virus. The Herpetic Eye Disease Study, as well as prior studies from Moorfields Eye Hospital and the Mayo Clinic in Rochester, Minnesota, provides us with the epidemiology of ocular herpes simplex. Recent studies suggest an older age of onset and perhaps overall more severe ocular disease as compared with the older literature. CONCLUSIONS Herpes simplex is a significant health concern at present with genital infections increasing in epidemic proportions. This is also reflected in a rise in the incidence of neonatal herpes. Herpes simplex virus type 1 (HSV-1) infection is being acquired for the first time in an older age group. A significant and increasing proportion of genital herpes is caused by HSV-1. Serologic studies are no longer as useful in distinguishing orofacial herpes from genital herpes. More acute retinal necrosis syndrome cases are associated with HSV-2. Speculation about the future of ocular herpes is made based on this changing epidemiology.

Abstract
OBJECTIVE Serological evaluation of herpes simplex virus infections during pregnancy. METHODS 2991 serum samples were obtained during 1st, 2nd, and 3rd trimester from 997 pregnant women. Baculovirus expressed glycoproteins gG1 (HSV-1) and gG2 (HSV-2) were used as antigens in ELISA for HSV-1 and HSV-2 IgG and IgA antibodies. RESULTS The prevalence of HSV-1 gG1 antibodies was 70% and that of HSV-2 gG2 antibodies 16%. Among susceptible women we found five (0.6%) cases with serological evidence of primary HSV-2 infection during pregnancy. Evidence of active HSV-1 infection was found in nine (0.9%) cases. Decline of HSV-2 gG2 IgG antibody levels during pregnancy was pronounced compared with HSV-1 gG1 IgG antibody levels (p < 0.01); also the proportion of seroreversions was considerably higher among HSV-2 seropositives (25%) than among HSV-1 seropositives (3%) (p < 0.001). CONCLUSIONS HSV-2 gG2 IgG antibodies were readily distinguished from HSV-1 gG1 IgG antibodies by the glycoprotein gG ELISAs. Serological assays for gG2 antibodies should guard against the decline of specific antibodies during pregnancy.

Abstract
BACKGROUND identification and discrimination of latent herpes simplex virus (HSV) infection relies on antibody identification. The inclusion of synthetic peptides with HSV glycoproteins provides means for stable and discriminatory assays for population studies. OBJECTIVE to determine whether virus-specific synthetic peptides might identify HSV type 2 (HSV-2) antibodies in the presence of the cross-reactive and more common HSV type 1 (HSV-1) antibodies. STUDY DESIGN the capacity of synthetic peptides as HSV antigens was analyzed in enzyme immunoassay (EIA) using well characterized human serum cohorts. The HSV peptide assays were evaluated in comparison with two commercial HSV-2 assays. RESULTS a combination of two C-terminal HSV-1 glycoprotein D (gD-1) peptides detected type-common HSV immunoglobulin G (IgG) with high sensitivity (95%) and specificity (93%). Peptides derived from the C-terminus of HSV-2 glycoprotein G (gG-2) had a high HSV-2 type-specificity. Inclusion of both gD-1 and gG-2 peptides gave a sensitivity for human anti-HSV-2 IgG that was similar to that of assays including different amounts of native gG-2. With western blotting as a standard, the sensitivity of the peptide assay ranged between 86% for HSV-2 seropositive persons and 61% for HSV-2 seroconverters. Addition of a small amount of native gG-2 to the peptide assay tended to increase the specificity. CONCLUSION HSV gG and gD peptides show promise as type-specific and type-common HSV antigens. These peptides are more stable and reproducibly prepared than native or recombinant glycoproteins and may be considered for inclusion in future HSV serodiagnostic assays.

Abstract
BACKGROUND Genital infection with herpes simplex virus (HSV) is common and can cause severe morbidity, over many years in some cases. Aciclovir provides suppressive therapy but there is debate over the effects of its use on the spread of infection. OBJECTIVES To explore the influence of the natural history of genital HSV and the impact of antiviral therapy. METHODS A simple mathematical model of HSV-2 transmission dynamics was developed, and parameter values estimated from published data. RESULTS The relative durations of the risk of transmitting HSV-2 and the duration of therapy generate a non-linear relation between the duration of antiviral therapy and the reduction in prevalence infection. If there is a wide distribution of risk of HSV-2 transmission over the course of an infection then practicable aciclovir use is unlikely to have any great impact on disease transmission dynamics. CONCLUSIONS There are still many uncertainties in the transmission dynamics of HSV-2. In particular, infectiousness over the course of an infection requires more detailed exploration. To have a significant impact on the prevalence of HSV-2 aciclovir use would have to be widespread and for a long duration.

Abstract
Prevention of genital herpes simplex virus (HSV) infections is desirable from both a public health standpoint and the patient's perspective. A key factor in the spread of genital herpes infections is the high proportion of undiagnosed infections. Persons with subclinical or unrecognized infections are best diagnosed by accurate, type-specific antibody tests. Unfortunately, these tests are only now becoming widely available. The use of current, conventional (non-type-specific) serologic tests for diagnosis of herpes infections has resulted in confusion and misdiagnosis of patients. This review provides recent information on the epidemiology of genital herpes infections, describes the importance of subclinical herpes infection and shedding, summarizes the status of HSV type-specific serologic assays being developed, and provides indications for using such assays.

Abstract
OBJECTIVES To measure the prevalence of HSV-2 antibodies in a birth cohort of 21 year old New Zealanders from whom detailed sexual histories had been obtained, and to assess the potential for HSV-2 serology in characterising a young adult population's risk for sexually transmitted diseases (STD). METHODS Sera from 784 cohort members were tested using an indirect IgG enzyme linked immunoassay specific to the HSV-2 glycoprotein G. Positive results were confirmed by western blot. RESULTS In all, 27 subjects were seropositive for HSV-2 (3.4%), only seven of whom gave a history of genital herpes (26%). Risk among females increased with lifetime number of partners, while risk for males increased with having a first partner who was aged 16 years or under. CONCLUSIONS The seroprevalence of HSV-2 infection in this cohort was low, but similar to that seen in several other populations in this age group. HSV-2 seropositivity did not appear to be a sensitive marker for high risk sexual activity in this young population. This may be because a critical mass of HSV-2 carriers has not accumulated among potential partners by age 21 years.

Abstract
BACKGROUND AND OBJECTIVES Genital herpes remains one of the most prevalent sexually transmitted diseases (STDs). The sexual behavioral correlates of herpes simplex virus type 2 (HSV-2) infection in the general population have not been well characterized. GOALS To assess demographic and sexual behavioral correlates of symptomatic and subclinical HSV-2 infection. STUDY DESIGN Cross-sectional survey of 922 randomly chosen patients and 78 of their partners (1,000 total) in a family practice. Sexual behavior information was collected in 492 people. RESULTS Two hundred twenty-five (23%) heterosexual people had HSV-2 infection, but only 59 (26%) reported a history of genital herpes. HSV-2 seroprevalence was 63% in African-American women, 27% in white women, 40% in African-American men, and 12% in white men. In multivariate analyses of risk factors for HSV-2 infection among men, 10 or more sexual partners and a prior STD were statistically significantly associated with HSV-2 infection. Among white women, number of sexual partners, a prior STD, marriage or cohabitation, and less than a college education were predictive of HSV-2 infection. A history of oral sex was the only statistically significant predictor of HSV-2 infection in African-American women. CONCLUSIONS Risk factors for HSV-2 infection differ by gender and ethnic group. Traditionally recognized behavioral correlates of STD acquisition may not identify people in communities with high prevalence of HSV-2 infection.

Abstract
BACKGROUND The incidence of genital herpes is increasing worldwide. Herpes simplex virus type 2 (HSV-2) is the most common cause of genital ulcerations among the sexually transmitted diseases (STDS). In order to investigate the sexual transmission of genital herpes infection in Brazil, the prevalence of specific antibodies to HSV-2, in populations of high and low risk for STDS was evaluated. METHODS The population at low risk for STDS was composed of 155 voluntary blood donors at the University Hospitals between February and August, 1994. The population at high risk for STDS was composed of 85 HIV-seropositive persons, consisting of homosexual and promiscuous heterosexual men. A group of 20 highly active prostitutes was also studied between May and July, 1994. All blood samples were screened using an enzyme-linked immunosorbent assay (ELISA) that detects type-specific antibodies to HSV-2 glycoprotein G. Before donating blood, all persons in the study group were given a questionnaire concerning risk factors for acquisition of STDS and suitable to show the socioepidemiologic characteristics of the subjects. RESULTS The prevalence of ELISA showing HSV-2 infections among HIV-seroposite persons, was 73% (P < 0.01). In the whole group at high risk for STDS, the prevalence was 72% (P < 0.05). Infection with HSV-2, as determined by seroprevalence, was significantly and independently associated with years of sexual activity, history of previous STDS, number of sexual partners in the previous month, number of pregnancies, and previous induced abortions, as well as the percentage of sexual acts involving receptive anal intercourse. CONCLUSIONS The current strategy for diagnosing genital HSV-2 infection misses many cases. Newly developed type-specific serologic methods can identify cases of unrecognized or subclinical infection. With the high seroprevalence rates detected, routine screening for HSV-2-specific antibodies should be considered in populations at high risk for STDS.

Abstract
Seropositivity to herpes virus type 1 (HSV-1), herpes virus type 2 (HSV-2), cytomegalovirus (CMV) and Epstein-Barr virus (EBV) was estimated in a group of 98 16-year-old Swedish girls. Antibodies to HSV-1 were seen in 41% of the girls and to HSV-2 in 1%, and antibodies to CMV in 45 and to EBV in 82%. In girls with coitus experience, there was significantly higher prevalence of HSV-1 and EBV antibodies, compared with girls with no sexual contact. The age of coitarche or number of coitus partners did not affect the rate of seropositivity. During 2 years of follow-up, 13 girls seroconverted. All but one EBV-seroconverting girl, were sexually active, and no girl converted for more than one type of virus. We concluded that transmission of herpes viruses is common in adolescence, and sexuality, even with regard to its close association with kissing, is one important determinant.
