The ripple effect: why promoting female leadership in global health matters.

Leadership positions in global health are greatly skewed toward men; the imbalance is more pronounced in low- and middle-income countries (LMICs). The under-representation of women in leadership is a threat to gender equality, and also impacts the improvement of women's health outcomes globally. In this perspectives piece, we assert that the promotion and retention of women in global health leadership has a ripple effect that can achieve improvement in global health outcomes. We present pragmatic, actionable solutions to promote and retain female global health leaders in this field.

Les positions de dirigeant dans la santé du monde sont largement orientées vers les hommes et ce déséquilibre est encore plus prononcé dans les pays à revenu faible et moyen. La sous-représentation des femmes en termes de dirigeant menace l'égalité des genres et a également un impact sur l'amélioration de l'état de santé des femmes dans le monde. Dans cette perspective, nous affirmons que la promotion et la rétention des femmes au sein du leadership de la santé dans le monde a un effet d'entraînement qui peut aboutir à une amélioration de l'état de santé dans le monde. Nous présentons des solutions pragmatiques et réalisables pour promouvoir et retenir des leaders féminins en matière de santé dans le monde.

Los puestos directivos en materia de salud mundial se asignan de manera desproporcionada a los hombres; este desequilibrio es aun más notorio en los países de ingresos bajos y medianos. La subrepresentación de las mujeres en los cargos de responsabilidad pone en peligro la equidad entre los hombres y las mujeres y tiene además repercusiones en los resultados de salud de las mujeres en el mundo. En el presente artículo de opinión, se sostiene que promover a las mujeres a las funciones directivas relacionadas con la salud mundial y facilitar su permanencia en ellas genera una reacción en cadena que puede dar lugar a mejores resultados de salud a escala mundial. Se proponen soluciones viables y prácticas encaminadas a estimular la presencia de las mujeres en los cargos de responsabilidad en materia de salud mundial y a respaldar su permanencia en esta actividad.

Sensitivity and specificity of herpes simplex virus-2 serological assays among HIV-infected and uninfected urban Ugandans.

Herpes simplex virus type 2 (HSV-2) is a risk factor for HIV-1 infection. We characterized HSV-2 serology assay performance in HIV-positive and HIV-negative Africans. Serostatus for HSV-2 and HIV-1 was determined in 493 serum specimens stored from a community HSV-2 prevalence survey in Kampala, Uganda. HSV-2 serology by Focus HerpeSelect ELISA, Biokit HSV-2 rapid assay and Kalon HSV-2 was compared with HSV-2 Western blot (WB) according to HIV-1 serostatus. Sensitivity/specificity was: 99.5%/70.2% for Focus, 97.0%/86.4% for Biokit and 97.5%/96.2% for Kalon. Focus with Biokit confirmation improved sensitivity/specificity (99.4%/96.8%, respectively). Use of a higher Focus index value cut-off of 2.2 instead of 1.1 increased specificity from 70.2% to 92.4%. Kalon had higher specificity than Focus (P < 0.001). Of commercially available HSV-2 serological assays, Kalon alone, or Focus ELISA followed by Biokit confirmation perform best. Improved HSV-2 assays are needed for HSV-2 and HIV-1 public health activities in Africa.

Acyclovir and transmission of HIV-1 from persons infected with HIV-1 and HSV-2.

BACKGROUND: Most persons who are infected with human immunodeficiency virus type 1 (HIV-1) are also infected with herpes simplex virus type 2 (HSV-2), which is frequently reactivated and is associated with increased plasma and genital levels of HIV-1. Therapy to suppress HSV-2 reduces the frequency of reactivation of HSV-2 as well as HIV-1 levels, suggesting that suppression of HSV-2 may reduce the risk of transmission of HIV-1. METHODS: We conducted a randomized, placebo-controlled trial of suppressive therapy for HSV-2 (acyclovir at a dose of 400 mg orally twice daily) in couples in which only one of the partners was seropositive for HIV-1 (CD4 count, > or = 250 cells per cubic millimeter) and that partner was also infected with HSV-2 and was not taking antiretroviral therapy at the time of enrollment. The primary end point was transmission of HIV-1 to the partner who was not initially infected with HIV-1; linkage of transmissions was assessed by means of genetic sequencing of viruses. RESULTS: A total of 3408 couples were enrolled at 14 sites in Africa. Of the partners who were infected with HIV-1, 68% were women, and the baseline median CD4 count was 462 cells per cubic millimeter. Of 132 HIV-1 seroconversions that occurred after randomization (an incidence of 2.7 per 100 person-years), 84 were linked within couples by viral sequencing: 41 in the acyclovir group and 43 in the placebo group (hazard ratio with acyclovir, 0.92, 95% confidence interval [CI], 0.60 to 1.41; P=0.69). Suppression with acyclovir reduced the mean plasma concentration of HIV-1 by 0.25 log(10) copies per milliliter (95% CI, 0.22 to 0.29; P<0.001) and the occurrence of HSV-2-positive genital ulcers by 73% (risk ratio, 0.27; 95% CI, 0.20 to 0.36; P<0.001). A total of 92% of the partners infected with HIV-1 and 84% of the partners not infected with HIV-1 remained in the study for 24 months. The level of adherence to the dispensed study drug was 96%. No serious adverse events related to acyclovir were observed. CONCLUSIONS: Daily acyclovir therapy did not reduce the risk of transmission of HIV-1, despite a reduction in plasma HIV-1 RNA of 0.25 log(10) copies per milliliter and a 73% reduction in the occurrence of genital ulcers due to HSV-2.

High risk of human immunodeficiency virus in men who have sex with men with herpes simplex virus type 2 in the EXPLORE study.

The relation between herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus (HIV) acquisition was evaluated among 4,295 high-risk, HIV-negative men who have sex with men in an intensive behavioral intervention (colloquially referred to as "EXPLORE") study in the United States from 1999 to 2003. Sexual behavior data were obtained by computer-assisted self-interview, and sera were collected semiannually for HIV and HSV-2 serology. HSV-2 infection was classified as "recent incident" (at the first HSV-2 seropositive visit), "remote incident" (within 24 months of the first positive visit), and "prevalent" (for visits >24 months after the first HSV-2 positive visit). Baseline HSV-2 prevalence was 20.3%. HSV-2 incidence was 1.9 (95% confidence interval (CI): 1.6, 2.2) per 100 person-years; significant risk factors were African-American race, unprotected receptive anal intercourse, an HIV-positive male sex partner, and six or more male partners in the prior 6 months. The behavioral intervention did not reduce HSV-2 acquisition (adjusted hazard ratio (HR) = 1.2, 95% CI: 0.9, 1.6). Overall HIV incidence was 1.9 (95% CI: 1.7, 2.2) per 100 person-years. HIV risk was elevated among men who have sex with men with recent incident HSV-2 (adjusted HR = 3.6, 95% CI: 1.7, 7.8), remote incident HSV-2 (adjusted HR = 1.7, 95% CI: 0.8, 3.3), and prevalent HSV-2 (adjusted HR = 1.5, 95% CI: 1.1, 2.1) infection compared with HSV-2 seronegative participants. HIV intervention strategies targeting HSV-2 prevention and suppression among men who have sex with men should be evaluated.

Excellent safety and tolerability of the human immunodeficiency virus type 1 pGA2/JS2 plasmid DNA priming vector vaccine in HIV type 1 uninfected adults.

A vaccine consisting of DNA priming followed by recombinant modified vaccinia Ankara (rMVA) boosting has achieved long-term control of a pathogenic challenge with a chimera of simian and human immunodeficiency viruses (SHIV-89.6P) in rhesus macaques. Based on these results, clade B HIV-1 DNA and rMVA immunogens have been developed for trials in humans. We conducted a first-time in humans phase I safety trial using the pGA2/JS2 (JS2) HIV-1 DNA priming vector expressing Gag, Pol, Env, Tat, Rev, and Vpu. Thirty HIV-uninfected adults were vaccinated with 0.3 or 3 mg of JS2 DNA, or a saline placebo, by intramuscular injection at months 0 and 2. Both doses of DNA were safe and well-tolerated with no differences between the control, 0.3 mg, or 3 mg groups (n = 6, 12, and 12, respectively) through 12 months of postvaccination follow- up. A chromium-release assay using fresh peripheral blood mononuclear cells (PBMCs) and a validated IFN-gamma ELISpot assay with frozen PBMCs failed to detect CD4(+) or CD8(+) HIV-1-specific T cell responses. HIV-specific neutralizing antibodies were also not detected. The vaccine is being further developed as a priming vector for a combined DNA plus rMVA prime/boost HIV vaccination regimen.

HIV serodiscordant sex partners and the prevalence of human herpesvirus 8 infection among HIV negative men who have sex with men: baseline data from the EXPLORE Study.

OBJECTIVES: Human herpesvirus 8 (HHV-8) infection is common among men who have sex with men (MSM), especially those infected with HIV, and is frequently detected in saliva. We sought to determine whether oral or anogenital contact with HIV discordant, or unknown serostatus sexual partners is associated with HHV-8 seroprevalence among HIV negative MSM. METHODS: HIV negative MSM participating in a behavioural intervention trial for the prevention of HIV infection (the EXPLORE study) were recruited from the Seattle and Denver areas for participation in this cross sectional study. Participants completed detailed questionnaires regarding sexual behaviour, focusing on activities with possible exposure to the oropharynx. Serum samples from study enrollment were tested for the presence of HHV-8 antibodies using whole virus enzyme immunoassay and immunofluorescence assay to latent and lytic proteins. RESULTS: 198/819 MSM (24.3%) were HHV-8 antibody positive. Exposure to saliva with HIV positive and HIV unknown serostatus sex partners was reported by 83% and 90% of all men, respectively. In a multivariate model, reporting more than the median number of lifetime sex partners (OR 2.2, p = 0.03) or lifetime sex partners of unknown HIV status (OR 1.7, p = 0.03), and the performance of oro-anal sex ("rimming") on partners whose HIV status is unknown (OR 2.7, p = 0.04) were independently associated with HHV-8 infection. CONCLUSIONS: The oropharynx may be an important anatomical site in HHV-8 acquisition, and contact with HIV serodiscordant or unknown sex partners is associated with higher HHV-8 seroprevalence among HIV negative MSM.

Don't ask, don't tell: patterns of HIV disclosure among HIV positive men who have sex with men with recent STI practising high risk behaviour in Los Angeles and Seattle.

OBJECTIVES: A high incidence of HIV continues among men who have sex with men (MSM) in industrialised nations and research indicates many MSM do not disclose their HIV status to sex partners. Themes as to why MSM attending sexually transmitted infection (STI) clinics in Los Angeles and Seattle do and do not disclose their HIV status are identified. METHODS: 55 HIV positive MSM (24 in Seattle, 31 in Los Angeles) reporting recent STI or unprotected anal intercourse with a serostatus negative or unknown partner from STI clinics underwent in-depth interviews about their disclosure practices that were tape recorded, transcribed verbatim, coded, and content analysed. RESULTS: HIV disclosure themes fell into a continuum from unlikely to likely. Themes for "unlikely to disclose" were HIV is "nobody's business," being in denial, having a low viral load, fear of rejection, "it's just sex," using drugs, and sex in public places. Themes for "possible disclosure" were type of sex practised and partners asking/disclosing first. Themes for "likely to disclose" were feelings for partner, feeling responsible for partner's health, and fearing arrest. Many reported non-verbal disclosure methods. Some thought partners should ask for HIV status; many assumed if not asked then their partner must be positive. CONCLUSIONS: HIV positive MSM's decision to disclose their HIV status to sex partners is complex, and is influenced by a sense of responsibility to partners, acceptance of being HIV positive, the perceived transmission risk, and the context and meaning of sex. Efforts to promote disclosure will need to address these complex issues.

Homozygous and heterozygous CCR5-Delta32 genotypes are associated with resistance to HIV infection.

OBJECTIVE: To investigate evidence for resistance to HIV-1 infection associated with the heterozygous genotype CCR5-+/Delta32 and with the homozygous genotype CCR5-Delta32/Delta32, which results in a nonfunctional CCR5 receptor. DESIGN: Cohort study of initially HIV-seronegative high-risk individuals from eight different cities. Enrollment data were analyzed to investigate the association of demographic factors and risk behaviors with CCR5 genotypes on the assumption that increased genotype prevalence among persons with histories of longer or more intensive exposure to HIV would indicate HIV resistance associated with that genotype. Longitudinal data were analyzed to investigate the association of HIV seroincidence with CCR5 genotypes. The cohort of 2996 individuals included 1892 men who have sex with men (MSM), 474 male injection drug users (IDUs), 347 women at heterosexual risk, and 283 female IDUs. MEASUREMENTS: CCR5 genotype, HIV serostatus, demographic factors, and risk behaviors during the 6 months before enrollment, followed by measurement of HIV seroincidence during the subsequent 18 months (for men) and 24 months (for women). RESULTS: Forty (1.3%) subjects were homozygous CCR5-Delta32/Delta32 and 387 (12.9%) were heterozygous CCR5-+/Delta32. All but 1 CCR5-Delta32/Delta32 individuals and 51 CCR5-+/Delta32 individuals were Caucasian. Among 1531 Caucasian MSM, CCR5-+/Delta32 individuals were present more frequently (22.3%) among those reporting unprotected receptive anal intercourse than among those not reporting this risk (15.9%) (p =.002), suggesting a selective advantage of the heterozygous genotype. CCR5-+/Delta32 individuals also had a significantly reduced relative risk of HIV seroconversion adjusted for unprotected receptive anal intercourse compared with CCR5-/+ individuals (relative risk = 0.30, 95% confidence interval [CI]: 0.08-0.97). CCR5-Delta32/Delta32 prevalence among Caucasian MSM was significantly associated with age among subjects recruited from high HIV seroprevalence cities (New York City and San Francisco) (odds ratio [OR] for each decade increase in age = 2.57, CI: 1.56-4.21) but not among those recruited from lower HIV prevalence sites (Boston, Chicago, Philadelphia, Seattle, and Providence/Pawtucket, Rhode Island) (OR = 1.20, CI: 0.75-1.89). CONCLUSIONS: Cross-sectional and longitudinal analyses indicated that among high-risk HIV seronegative MSM, CCR5-+/Delta32 and CCR5-Delta32/Delta32 are associated with protection against HIV infection. These findings imply that strategies aimed at reducing susceptibility to HIV infection by blocking CCR5 receptor sites need not seek blockage of all receptor sites to achieve an imperfect but substantial degree of protection.

Demographic rather than behavioral risk factors predict herpes simplex virus type 2 infection in sexually active adolescents.

BACKGROUND: Despite the high prevalence of herpes simplex virus type 2 (HSV-2) infection in adults and data indicating that many HSV-2 infections are acquired in late adolescence, the demographic and sexual behavior correlates of HSV-2 infection in high risk adolescents have not been extensively studied. METHODS: Using a cross-sectional design we evaluated serologic evidence of HSV-2 infection in 381 adolescents age 14 to 19 years at an urban sexually transmitted disease clinic and a community clinic. Study enrollment was offered to all patients participating in a project offering free hepatitis B vaccine. Participants were interviewed and blood was drawn for HSV Western blot. RESULTS: Twelve percent [95% confidence interval (CI), 8.6 to 15.1] of 379 adolescents in this study had antibodies to HSV-2. Only 22% of HSV-2-seropositive youth reported a history of herpes. Seropositivity for HSV-2 was significantly associated with African-American race (odds ratio, 2.3; 95% CI 1.1 to 4.8) and female gender (odds ratio, 6.0; 95% CI 2.3 to 15.9); 25% of the African-American girls were HSV-2-seropositive. Self-reported condom use, number of sexual partners in the prior 2 months and history of a sexually transmitted disease did not predict HSV-2 antibody status. CONCLUSIONS: HSV-2 infection among adolescents was prevalent, particularly among African-American girls, and correlated with demographic rather than behavioral variables. As in adults most HSV-2 infections were unrecognized. These data suggest that type-specific serologic testing for HSV-2 infection should be considered in sexually active adolescents. Prevention efforts should target children before initiation of sexual activity.

Urine-based screening for Chlamydia trachomatis in men attending sexually transmitted disease clinics.

BACKGROUND: Nucleic acid-amplified tests for Chlamydia trachomatis are accurate but costly. Screening strategies for asymptomatic men are needed. GOAL: To assess C trachomatis screening strategies for asymptomatic males. STUDY DESIGN: Men attending a sexually transmitted disease clinic were tested for C trachomatis with ligase chain reaction and culture, and for urethral inflammation with urine leukocyte esterase and urethral Gram stain. RESULTS: C trachomatis prevalence was 5.5% among 1,625 asymptomatic men. Ligase chain reaction increased detection by 49% among men without urethral inflammation. An age of younger than 25 years and urethral inflammation were associated with positive ligase chain reaction results. The negative predictive value of urine leukocyte esterase was highest among older men, but urethral Gram stain was equally sensitive in predicting infection regardless of age. An age of younger than 30 years or urethral inflammation identified the highest proportion of infections (92%) and reduced the percentage of men screened by 43%. CONCLUSIONS: Urine ligase chain reaction increased C trachomatis detection, particularly among men without urethral inflammation. Testing all asymptomatic men younger than 30 years is optimal, whereas negative urine leukocyte esterase or urethral Gram stain results in men 30 years or older support no testing.

Safety and immunogenicity of a canarypox-vectored human immunodeficiency virus Type 1 vaccine with or without gp120: a phase 2 study in higher- and lower-risk volunteers.

Live attenuated viral vectors that express human immunodeficiency virus (HIV) antigens are being developed as potential vaccines to prevent HIV infection. The first phase 2 trial with a canarypox vector (vCP205, which expresses gp120, p55, and protease) was conducted in 435 volunteers with and without gp120 boosting, to expand the safety database and to compare the immunogenicity of the vector in volunteers who were at higher risk with that in volunteers at lower risk for HIV infection. Neutralizing antibodies to the MN strain were stimulated in 94% of volunteers given vCP205 plus gp120 and in 56% of volunteers given vCP205 alone. CD8(+) cytotoxic T lymphocyte cells developed at some time point in 33% of volunteers given vCP205, with or without gp120. Phase 3 field trials with these or similar vaccines are needed, to determine whether efficacy in preventing HIV infection or in slowing disease progression among vaccinees who become infected is associated with the level and types of immune responses that were induced by the vaccines in this study.

Are US populations appropriate for trials of human immunodeficiency virus vaccine? The HIVNET Vaccine Preparedness Study.

Questions exist about whether testing of preventive human immunodeficiency virus (HIV)-1 vaccines, which will require rapid recruitment and retention of cohorts with high HIV-1 seroincidence, is feasible in the United States. A prospective cohort study was conducted in 1995-1997 among 4,892 persons at high risk for HIV infection in nine US cities. At 18 months, with an 88% retention rate, 90 incident HIV-1 infections were observed (1.31/100 person-years (PY), 95% confidence interval (CI): 1.06, 1.61). HIV-1 seroincidence rates varied significantly by baseline eligibility criteria--1.55/100 PY among men who had sex with men, 0.38/100 PY among male intravenous drug users, 1.24/100 PY among female intravenous drug users, and 1.13/100 PY among women at heterosexual risk-and by enrollment site, from 0.48/100 PY to 2.18/100 PY. HIV-1 incidence was highest among those men who had sex with men who reported unprotected anal intercourse (2.01/100 PY, 95% CI: 1.54, 2.63), participants who were definitely willing to enroll in an HIV vaccine trial (1.96/100 PY, 95% CI: 1.41, 2.73), and women who used crack cocaine (1.62/100 PY, 95% CI: 0.92, 2.85). Therefore, cohorts with HIV-1 seroincidence rates appropriate for HIV-1 vaccine trials can be recruited, enrolled, and retained.

Use of a glycoprotein G-based type-specific assay to detect antibodies to herpes simplex virus type 2 among persons attending sexually transmitted disease clinics.

BACKGROUND: Most genital herpes simplex virus type 2 (HSV-2) infections are unrecognized, thus, strategies to reduce the sexual transmission of HSV-2 are partly dependent on serologic screening. GOAL: To define performance characteristics of the Gull/ Meridian glycoprotein G-based HSV-2 enzyme-linked immunosorbent assay among sexually transmitted disease clinic attendees and correlates of test acceptance. STUDY DESIGN: The cross-sectional study was conducted during two periods. Serologic testing was offered at a US $15 charge during the first period and at no charge during the second period. Sera were tested by a type-specific glycoprotein G enzyme-linked immunosorbent assay and Western blot analysis, with the latter test used as the reference standard. RESULTS: Acceptance of HSV-2 testing was associated with free testing (odds ratio, 7.5; 95% CI, 6.0-9.9), older age, and white race. Sensitivity of the HSV-2 assay was 80.5% and specificity was 98.5%. The HSV-2 positive and negative predictive values were 95.8% (95% CI, 91.6-98.0%) and 92.2% (95 % CI, 89.6 -94.2%), respectively. Antibodies to HSV-2 were detected in 25.9% of 606 persons with no history of genital herpes. CONCLUSION: Acceptance of HSV-2 serologic testing was cost sensitive. In this high-prevalence population, the positive predictive value of the enzyme-linked immunosorbent assay was sufficient to warrant its use without a confirmatory test. This assay could be useful in the screening of sexually active adults to detect unrecognized HSV-2 infection.

The clinical manifestations and treatment of sexually transmitted diseases in human immunodeficiency virus-positive men.

Sexually transmitted diseases (STDs) occur commonly in sexually active human immunodeficiency virus (HIV)-positive men. STDs may have atypical presentations, can cause significant morbidity in persons with HIV infection, and may increase the risk of HIV transmission. Thus, the appropriate diagnosis and treatment of STDs in this population are extremely important. The clinical manifestations and treatment of several common STDs in HIV-positive men are reviewed. Further research is needed to define effective management and screening strategies for STDs in men with HIV infection.

Early human immunodeficiency virus (HIV) infection in the HIV Network for Prevention Trials Vaccine Preparedness Cohort: risk behaviors, symptoms, and early plasma and genital tract virus load.

Risk behaviors, symptoms, and virologic characteristics were studied among 103 human immunodeficiency virus (HIV) seroconverters in vaccine preparedness cohorts during 1995-1998. Overall, 83% of subjects were men who had sex with men; most reported multiple risk episodes and symptoms (84%, > or =1 symptom) during seroconversion. Acute HIV was diagnosed in only 8 of 50 who sought medical care. Median initial pretreatment plasma virus load was 25,800 copies/mL (range, undetectable-262,000 copies/mL) a mean of 4 months after seroconversion, and 9.7% had nucleoside-associated mutations; none had multidrug resistance. Semen virus load was more variable, 1.3 log(10) lower and modestly correlated (r=.28; 95% confidence interval, 0.16-0.42) with plasma among untreated men. When the plasma RNA level was <5000 copies/mL, 32% of untreated men, 13% on nucleoside regimens, and 7% on protease inhibitor-containing regimens had detectable seminal RNA. Acute HIV was seldom diagnosed, representing missed opportunities for early treatment and prevention. Most subjects had several relatively stable virus loads before initiation of antiretrovirals, indicating feasibility of assessing HIV vaccines on virus set point in efficacy trials.

Mucosal shedding of human herpesvirus 8 in men.

BACKGROUND: Epidemiologic studies suggest that human herpesvirus 8 (HHV-8) is sexually transmitted among men who have sex with men; however, the mode of transmission is unclear. METHODS: To evaluate the patterns of shedding of HHV-8, we obtained mucosal-secretion samples from a cohort of HHV-8-seropositive men who had sex with men and had no clinical evidence of Kaposi's sarcoma. Quantitative polymerase-chain-reaction (PCR) assays, in situ PCR assays, and in situ RNA hybridization were used to identify potential sources of infectious HHV-8. RESULTS: We detected HHV-8 in at least one mucosal sample from 30 of 50 men who were seropositive for HHV-8 (60 percent). Overall, HHV-8 was detected in 30 percent of oropharyngeal samples, as compared with 1 percent of anal and genital samples (P<0.001). In 39 percent of the HHV-8-seropositive men, HHV-8 was detected in saliva on more than 35 percent of the consecutive days on which samples were obtained. The median log titer of HHV-8 from the oral cavity was approximately 2.5 times as high as the titer at all other sites. In situ hybridization studies indicated that HHV-8 DNA and messenger RNA were present in oral epithelial cells. Among 92 men who had sex with men and who were seronegative for the human immunodeficiency virus (HIV), a history of sex with a partner who had Kaposi's sarcoma, deep kissing with an HIV-positive partner, and the use of amyl nitrite capsules ("poppers") or inhaled nitrites were independent risk factors for infection with HHV-8. CONCLUSIONS: Oral exposure to infectious saliva is a potential risk factor for the acquisition of HHV-8 among men who have sex with men. Hence, currently recommended safer sex practices may not protect against HHV-8 infection.

To notify or not to notify: STD patients' perspectives of partner notification in Seattle.

BACKGROUND AND OBJECTIVES: To obtain patients' perspectives on why only some partners are notified in partner-notification programs, the cornerstone of sexually transmitted disease (STD) control, although low proportions of partners are located and evaluated. GOALS: To describe patterns of partner notification reported by persons with STD infection. STUDY DESIGN: In-depth interviews conducted in Seattle with 60 heterosexual men and women with gonorrhea, chlamydial infection, or nongonoccocal urethritis, and 19 men with gonorrhea reporting sex with men (MSM) were tape recorded, transcribed verbatim, and content analyzed. RESULTS: The typical notification pattern was to notify a main partner but not others. Least likely to be notified were partners perceived as transmitters, contacts preceding the onset of symptoms, the oral sex and anonymous contacts of MSM, one-time partners of men, and incarcerated and former partners of women. Fears among young heterosexual participants included gossip and violence (women). Fears among MSM included rejection. CONCLUSIONS: Partner-notification programs should develop innovative approaches for partners perceived as transmitters, oral-sex only contacts of MSM, and contacts preceding symptom onset.

Herpes simplex virus type 1 as a cause of genital herpes: impact on surveillance and prevention.

This study compared characteristics of patients who had herpes simplex virus (HSV) type 1 with characteristics of patients who had HSV-2, by use of data from a cross-sectional analysis. Data were collected in an urban sexually transmitted diseases clinic from patients who had positive genital HSV cultures. Overall, 17.1% (95% confidence interval [CI], 14.9%-19.3%) of 1145 genital HSV isolates obtained during 1993-1997 were HSV-1. The proportion of HSV-1 among initial genital herpes infections was higher among men who had sex with men (46.9%) than among women (21.4%) and was lowest among heterosexual men (14.6%). White race (odds ratio [OR], 3.7; 95% CI, 2.3-5.9) and receptive oral sex in the preceding 2 months (OR, 2.8; 95% CI, 1.9-4.3) significantly increased the odds that initial infections were HSV-1 rather than HSV-2. Genital HSV-1 may often be acquired through contact with a partner's mouth. These data suggest that seroprevalence studies based solely on HSV-2 type-specific assays underestimate overall prevalence of genital HSV infection.

Herpes simplex virus type 2 shedding in human immunodeficiency virus-negative men who have sex with men: frequency, patterns, and risk factors.

We investigated the frequency, site, and risk factors for herpes simplex virus (HSV) shedding in 30 human immunodeficiency virus (HIV)-negative HSV type 2 (HSV-2)-seropositive men who have sex with men. Subjects collected daily HSV culture samples from genital, perianal, and oral areas for 100 days and maintained diaries of signs and symptoms. Sixteen men (53.3%) shed HSV-2, and 9 (56.3%) of 16 men who were also HSV type 1 (HSV-1)-seropositive shed HSV-1. Overall, HSV-2 was isolated on 3.1% of the days; 68% of the isolations were on days that lesions did not occur. HSV-2 shedding was predominantly perianal (83.3%). HSV-1 was isolated on 2.1% of the days; 23 of 24 HSV-1 isolates were from oral areas. Rates of perianal or genital shedding were 6.6% on the days that participants reported prodromal symptoms and 1.9% on the days that participants did not report prodromal symptoms (P<.001). Men seropositive for both HSV-1 and HSV-2 were significantly more likely to shed HSV-2 (odds ratio, 4.1; 95% confidence interval, 1.4-11.9) than were HSV-2-seropositive men. HSV-2-seropositive men who have sex with men have frequent subclinical HSV-2 shedding, usually from the perianal area, and more frequent prodromal HSV-2 shedding.
