Demographic, behavioral, and knowledge factors associated with herpes simplex virus type 2 infection among men whose current female partner has genital herpes

[Genital herpes and pregnancy: Serological and molecular diagnostic tools. Guidelines for clinical practice from the French College of Gynecologists and Obstetricians (CNGOF)]

OBJECTIVES

To describe serological and molecular tools available for genital and neonatal herpes, and their use in different clinical situations.

METHODS

Bibliographic investigations from MedLine database and consultation of international clinical practice guidelines.

RESULTS

Virological confirmation of genital herpes during pregnancy or neonatal herpes must rely on PCR (Professional consensus). HSV type-specific serology (IgG) will allow determining the immune status of a patient (in the absence of clinical lesions). However, there is currently no evidence to justify universal HSV serological testing during pregnancy (Professional consensus). In case of genital lesions in a pregnant woman that do not report any genital herpes before, it is recommended to perform a virological confirmation by PCR and HSV type-specific IgG in order to distinguish a true primary infection, a non-primary infection associated with first genital manifestation, from a recurrence (Grade C). HSV IgM is useless for diagnosis of genital herpes (Grade C). If a pregnant woman has personal history of genital herpes but no lesions, whatever the gestational age, it is not recommended to perform genital sampling nor serology (Professional consensus). In case of recurrence, if the lesion is characteristic of herpes, virological confirmation is not necessary (Professional Agreement). However, if the lesion is not characteristic, virological confirmation by PCR should be performed (Professional consensus). At birth, HSV PCR samples should be collected as soon as neonatal herpes is suspected (symptomatic neonate) (best before beginning antiviral treatment but must not delay the treatment), or after 24hours of life in case of asymptomatic neonate born to a mother with herpes lesions at delivery (Professional consensus). Clinical samples for virological confirmation should include at least blood and a peripheral location. In case of clinical manifestations of herpes in the neonate, first samples PCR positive, preterm birth, or maternal primary infection or non-primary infection associated with first genital manifestation at delivery, CSF should also be collected as well as samples of lesions in the neonate if present (Professional consensus). Sampling should be repeated in case of PCR negative but strong evidence of neonatal herpes (Professional consensus). HSV serology is useless for diagnosis of neonatal herpes (Grade C).

CONCLUSIONS

Virological confirmation for diagnosis of genital herpes during pregnancy or neonatal herpes must rely on PCR. PCR assays available in France are very reliable. Specific IgG are dedicated to restricted indications.

Herpes simplex virus 1 and 2 educational assessment of young adults in rural southwest Virginia

Purpose

Herpes simplex virus 2 (HSV-2) causes genital herpes, one of the most common sexually transmitted infections (STIs) in the U.S. HSV-1, commonly associated with cold sores, is increasing as a cause of genital herpes. Abstinence-only sexual health classes, commonly taught in Virginia, generate young adults who are under-educated in sexual health, increasing STI risks. College students in southwest Virginia were surveyed to assess comprehensiveness of high school health education regarding HSV-1 and HSV-2 and to identify students’ preferred methods for STI education.

Methods

To obtain data on knowledge of HSV, comprehensiveness of sexual health education in high school, and preferred learning methods, 237 college students participated in an online questionnaire and 28 students were interviewed using structured interviews.

Results

Questionnaire and interview data indicated that Family Life Education classes need to include more comprehensive information on prevention, viral transmission, and differences between HSV-1 and HSV-2. The majority of total respondents (both the questionnaire and interview) (65%) reported non-comprehensive high school sexual health education. The majority of interview (79%) and questionnaire (55%) respondents wished they had learned more about herpes and other STIs in high school. Education preferences of both interviewed and surveyed respondents included interactive internet programs or games, more realistic lectures, and learning about STIs later in high school when students reported greater sexual activity.

Conclusion

Our results indicate that more comprehensive sexual health education is needed and wanted by students in southwest Virginia. More relevant educational programs should be implemented for VA high school students utilizing technology and interactive methods to improve student engagement in sexual health education.

Implications and contribution

These studies provide information on knowledge of herpes simplex viruses among college students, comprehensiveness of sexual health education received in high schools, and preferred methods to learn about HSV and other STIs. These studies inform the facilitation of improved health education practices and programs for high school and college students.

Genital herpes beliefs: implications for sexual health

STUDY OBJECTIVE

Genital herpes (HSV) is exceedingly common in the United States and women are disproportionally affected. This study aims to describe young women's beliefs about HSV and examine the correlates of those beliefs.

DESIGN

A 40-item Herpes Representation measure (HSV-RoSTD) and a demographic questionnaire were administered to a convenience sample of young women. Data analysis included descriptive statistics, t-tests and Pearson's correlations.

SETTING

Four women's health clinics and one large state university.

PARTICIPANTS

302 women aged 18-24 years.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Four dimensions of HSV representations (cause, identity, future perspective, and psychosocial consequences), age and STD testing history.

RESULTS

Nearly all (98%) believed that HSV would result in genital sores and 68% believed they could tell if their sexual partner had HSV. Most (89%) understood the longevity of HSV; however, 30% believed that they could take a pill to get rid of the infection, and 15% indicated that it was likely they would die from HSV. Negative beliefs about the psychosocial impact of HSV were common as 95% indicated they would be depressed and 90% indicated concern about sex and partner notification. Those who were younger and those who had never been tested for STDs believed a genital herpes infection is highly symptomatic. Finally, negative beliefs about the psychosocial consequences of HSV were associated with beliefs about HSV being symptomatic, having a negative impact on future health, and being associated with sexual risk behaviors.

CONCLUSIONS

Young women have misconceptions about HSV, particularly regarding the symptomatology and the role of HSV medication. Noteworthy concerns about the negative psychosocial consequences of an HSV diagnosis were also raised, all of which have implications for young women's sexual health.

Seroprevalence of herpes simplex virus 1 and 2 in a population-based cohort in Japan

Background

There have been few population-based studies of the seroprevalence and correlates of herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) in Japan.

Methods

We enrolled a total of 1244 adults, aged 18–59 years, from a population-based cohort in southern Japan, and tested their serum samples using an ELISA kit containing HSV type-specific antigens to glycoproteins G1 and G2.

Results

The seroprevalence of HSV-1 and HSV-2 was 55.4% and 7.4% in men and 63.3% and 9.3% in women, respectively. Overall, 4 percent of the participants (2.3% of men and 5.0% of women) were co-infected with HSV-1 and HSV-2. The seroprevalences of both HSV-1 and HSV-2 increased with age in both sexes, and were always higher among women than among men in each age bracket. The prevalence of HSV-2 infection among HSV-1 infected individuals was lower than that among uninfected individuals, both in men and women. Male current drinkers, and male and female current smokers, were more likely to be infected with HSV-1 and HSV-2, as compared to never drinkers and never smokers, respectively.

Conclusion

It is hoped that the estimates produced in this study will help in understanding the burden of these infections in Japan.

[Herpes serology for genital herpes]

The epidemiology of genital herpes is changing. The seroprevalence of HSV-2 infections is increasing, while HSV-1 is an increasingly common cause of herpetic ulcerations. The reference examination provides direct diagnosis after viral isolation in a cell culture or genome amplification. Herpes serology is indicated principally if direct examination is negative and in the absence of lesions. Non-type-specific serology detects antibodies common to HSV-1 and HSV-2. Its specificity and sensitivity are excellent, and it is approved as a reimbursable laboratory procedure. It cannot specify the viral type involved. Type-specific serology can distinguish between anti-HSV-1 and anti-HSV-2 antibodies. Currently available kits have a sensitivity and specificity, depending on the population studied, of 90 to 100%. It is not approved as a reimbursable laboratory procedure. HSV-1-specific serology cannot diagnose old HSV-1 genital infections, but seropositivity for HSV-2 generally suffices to diagnose HSV-2 genital herpes. The indication for type-specific serology must be discussed according to clinical context. The value of non-type-specific serology is limited.

Sexual behaviour and condom use among individuals with a history of symptomatic genital herpes

OBJECTIVES

This study describes the differences in sexual behaviour in individuals with genital herpes (GH) during "symptomatic" and "asymptomatic" periods of the disease.

METHODS

A cross sectional questionnaire was undertaken by 1193 individuals attending clinics between 1998 and 2001. All participants in this analysis were in heterosexual, monogamous partnerships, self identified with a history of symptomatic GH and with confirmed HSV-2 infection.

RESULTS

Sexual activity reported during asymptomatic v symptomatic periods of GH was 98% v 40% (p<0.001), 76% v 29% (p<0.001), and 25% v 11% (p<0.001) for vaginal, oral, and anal intercourse, respectively, while "always" condom use during asymptomatic and symptomatic periods was 20% v 35% (p<0.001), 2% v 7% (p<0.001), and 10% v 15% (p = 0.131), respectively. The proportion of individuals who either abstained from vaginal intercourse or "always" used condoms was 21% v 74% (p<0.001), for asymptomatic v symptomatic periods. Multivariable analyses indicated that factors associated with engaging in intercourse during symptomatic periods of GH included current intrauterine device use (adjusted odds ratio (aOR) = 2.96, 95% confidence interval (CI) = 1.46 to 6.02); living in Latin America (aOR = 2.16, CI = 1.19 to 3.91) or Europe (aOR = 1.67, CI = 1.21 to 2.28), compared with North America; previous sexually transmitted disease (aOR = 1.42, CI = 1.08 to 1.89); a higher number of sexual acts per month (aOR = 1.09, CI = 1.06 to 1.11); and a higher number of GH recurrences per year (aOR = 1.08, CI = 1.03 to 1.12).

CONCLUSIONS

These data indicate that the majority of people with GH either abstained from intercourse or "always" used condoms during symptomatic periods of GH. However, condom use was relatively low during asymptomatic periods in comparison with symptomatic periods. These results highlight that further education on GH prevention is warranted, particularly for symptomatic periods.
