Background:Men who have sex with men are at high risk for HIV infection. Here we report the results of the first assessment of HIV prevalence and risk behaviour in this group in Vientiane, Lao Peoples Democratic Republic. Methods:Between August and September 2007, 540 men were enrolled from venues around Vientiane, using venue-day-time sampling. Men of Lao nationality, 15 years and over, reporting oral or anal sex with a man in the previous 6 months were eligible for participation. Demographic and socio-behavioural information was self-collected using hand-held computers. Oral fluid was tested for HIV infection. Logistic regression was used to evaluate risk factors for prevalent HIV infection. Results:The median age of participants was 21 years; the HIV prevalence was 5.6%. Of participants, 39.6% reported exclusive attraction to men and 57.6% reported sex with women. Of those who reported having regular and nonregular sexual partner(s) in the past 3 months, consistent condom use with these partners was 14.4 and 24.2%, respectively. A total of 42.2% self-reported any sexually transmitted infection symptoms and 6.3% had previously been tested for HIV. Suicidal ideation was reported by 17.0%, which was the only variable significantly and independently associated with HIV infection in multivariate analysis. Conclusion:Although the HIV prevalence is low compared with neighbouring countries in the region, men who have sex with men in Lao Peoples Democratic Republic are at high behavioural risk for HIV infection. To prevent a larger HIV epidemic occurrence and transmission into the broader community, higher coverage of HIV prevention interventions is required.

HIV prevalence and associated factors were examined among male sex workers (MSWs, N = 414) in Bangkok, Thailand. Cross-sectional venue-day-time sampling was used to collect data in entertainment and street venues. Chi-square and logistic regression were used to identify HIV risk factors. HIV prevalence was 18.8% overall, but differences were found between MSW recruited in entertainment and street venues. Significant relationships were found between several demographic, behavioral, exposure to HIV prevention, and other characteristics, and recruitment location. In multivariate analyses, being sexually attracted to men was significantly associated with HIV infection among both groups of sex workers. In addition, among street-based sex workers, not having had sex with a woman in the past 3 months, having ever had a sexually transmitted disease symptom, and not having a friend to talk to about personal problems were significantly associated with HIV infection.

Background The scale-up of voluntary medical male circumcision (VMMC) services in South Africa has been rapid, in an attempt to achieve the national government target of 4.3 million adult male circumcisions for HIV prevention by 2016. This study assesses the effect of the scale-up on the quality of the VMMC program. Methods and Findings This analysis compares the quality of services at 15 sites operational in 2011 to (1) the same 15 sites in 2012 and (2) to a set of 40 sites representing the expanded program in 2012. Trained clinicians scored each site on 29 items measuring readiness to provide quality services (abbreviated version of the WHO Quality Assessment [QA] Guide) and 29 items to assess quality of surgical care provided (pre-op, surgical technique and post-op) based on the observation of VMMC procedures at each site. Declines in quality far outnumbered improvements. The negative effects in terms of readiness to provide quality services were most evident in expanded sites, whereas the declines in provision of quality services tended to affect both repeat sites and expanded sites equally. Areas of notable concern included the monitoring of adverse events, external supervision, post-operative counselling, and some infection control issues. Scores on quality of surgical technique tended to be among the highest across the 58 items observed, and the South Africa program has clearly institutionalized three “best practices” for surgical efficiency. Conclusions These findings demonstrate the challenges of rapidly developing large numbers of new VMMC sites with the necessary equipment, supplies, and protocols. The scale-up in South Africa has diluted human resources, with negative effects for both the original sites and the expanded program.

In 1998, the U.S. government launched the Minority AIDS Initiative (MAI) to address growing ethnic and racial disparities in HIV/AIDS cases. The CDC performed an evaluation of its MAI-funded programs, including an assessment of community stakeholders’ perspective on the involvement of the faith community in HIV prevention. Individual interviews (N = 113) were conducted annually over 3 years in four communities. The majority of participants described a change in faith community’s attitudes toward HIV and a rise in HIV-related activities conducted by faith-based organizations. Participants attributed changes to faith-based funding, acknowledgment by African American community leadership that HIV is a serious health issue, and faith leaders’ desire to become more educated on HIV/AIDS. Participants reported conservative faith doctrine and stigma as barriers to faith community involvement. The findings suggest that although barriers remain, there is an increased willingness to address HIV/AIDS, and the faith community serves as a vital resource in HIV prevention.

In the context of monitoring and improving CDC-funded HIV prevention programs, we describe HIV tests and infections, provision of results, previous HIV tests, and risk behaviors for young (aged 13–29) men of color who have sex with men who received HIV tests at five community-based organizations. Of 1,723 tests provided, 2.1% were positive and 75.7% of positives were previously unaware of their infection. The highest positivity rate was among men aged 25–29 (4.7%). Thirty-four percent of tests were provided to men who were tested for the first time. Over half the tests (53.2%) were provided to men who reported sex with a person of unknown HIV status, and 34% to men who reported sex with an anonymous partner. Continued and more focused prevention efforts are needed to reach and test young men of color who have sex with men and to identify previously undiagnosed HIV infections among this target population.

This report describes characteristics of HIV test data for men who have sex with men (MSM) tested in 2007 through programs funded by the Centers for Disease Control and Prevention (CDC). HIV test-level data of MSM submitted by 29 health departments were analyzed to explore test characteristics among all tests, first-time tests, and repeat tests. Characteristics significantly associated with HIV-positive results among first-time tests were identified through logistic regression. Of the 129,893 tests conducted, 18% were first-time tests and 82% were repeat tests. HIV positivity among first-time tests was 4.1% and 3.7% among repeat tests. Among first-time tests, 46% of tests were among White MSM and 48% of HIV-positive test results were among African Americans. An HIV-positive test among first-time tests was strongly associated with being African American, being 40-49 years old, and testing in the southern United States. Race/ethnicity differences exist among MSM testing at CDC-funded sites. African American MSM accounted for the greatest proportion of HIV-positive results but White MSM represented the greatest proportion of tests conducted. HIV prevention strategies that include CDC-funded testing for MSM should increase targeting of African Americans.

Objective. The Minority AIDS Initiative (MAI) was launched in 1998 to address the disproportionate rates of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) among racial and ethnic minorities in the United States. The Centers for Disease Control and Prevention (CDC) conducted an evaluation to assess the influence of MAI in four communities, and the extent to which these communities increased their capacity to meet the HIV prevention needs of racial and ethnic minorities. Design. Retrospective data were collected annually through individual interviews over three years. Individual interviews were conducted with community stakeholders across the three waves of data collection. Data were analyzed using standardized qualitative methods including codebook development, coding, inter-coder agreement assessments, and data interpretation. This paper will highlight one area of inquiry—community stakeholders’ perceptions of the impact of MAI in their communities. Results. Community stakeholders reported that MAI increased capacity to respond to the HIV epidemic and provide services to racial and ethnic minorities. Specifically, MAI was perceived to have increased community empowerment, involvement, and awareness of HIV/AIDS; expanded HIV-related services and organizational self-sufficiency; and improved collaboration and the coordination of services in the community. Although recognizing MAI gave national focus to the impact of the epidemic on minority communities, respondents raised concerns about the implementation process and the lack of sustainability planning. Conclusion. MAI represented an initial national attempt to address the disproportionate rates of HIV/AIDS among racial and ethnic minorities. However, other strategies are also needed to address these significant health disparities. At CDC, steps are currently underway to develop a comprehensive strategy to prevent and reduce the burden of HIV/AIDS among racial and ethnic minorities. As community stakeholders are critical partners in the effort to prevent the spread of HIV, strengthening their capacity and promoting their involvement can help combat the epidemic.

Summary Background Male circumcision reduces men’s risk of acquiring HIV and some sexually transmitted infections from heterosexual exposure, and is essential for HIV prevention in sub-Saharan Africa. Studies have also investigated associations between male circumcision and risk of acquisition of HIV and sexually transmitted infections in women. We aimed to review all evidence on associations between male circumcision and women’s health outcomes to benefit women’s health programmes. Methods In this systematic review we searched for peer-reviewed and grey literature publications reporting associations between male circumcision and women’s health outcomes up to April 11, 2016. All biomedical (not psychological or social) outcomes in all study types were included. Searches were not restricted by year of publication, or to sub-Saharan Africa. Publications without primary data and not in English were excluded. We extracted data and assessed evidence on each outcome as high, medium, or low consistency on the basis of agreement between publications; outcomes found in fewer than three publications were indeterminate consistency. Findings 60 publications were included in our assessment. High-consistency evidence was found for five outcomes, with male circumcision protecting against cervical cancer, cervical dysplasia, herpes simplex virus type 2, chlamydia, and syphilis. Medium-consistency evidence was found for male circumcision protecting against human papillomavirus and low-risk human papillomavirus. Although the evidence shows a protective association with HIV, it was categorised as low consistency, because one trial showed an increased risk to female partners of HIV-infected men resuming sex early after male circumcision. Seven outcomes including HIV had low-consistency evidence and six were indeterminate. Interpretation Scale-up of male circumcision in sub-Saharan Africa has public health implications for several outcomes in women. Evidence that female partners are at decreased risk of several diseases is highly consistent. Synergies between male circumcision and women’s health programmes should be explored.

Voluntary medical male circumcision (VMMC) decreases the risk for female-to-male HIV transmission by approximately 60%, and the Presidents Emergency Plan for AIDS Relief (PEPFAR) is supporting the scale-up of VMMC for adolescent and adult males in countries with high prevalence of human immunodeficiency virus (HIV) and low coverage of male circumcision. As of September 2015, PEPFAR has supported approximately 8.9 million VMMCs.

BACKGROUND In high HIV burden settings, maximising the coverage of prevention strategies is crucial to achieving epidemic control. However, little is known about the reach and effect of these strategies in some communities. METHODS We did a cross-sectional community survey in the adjacent Greater Edendale and Vulindlela areas in the uMgungundlovu district, KwaZulu-Natal, South Africa. Using a multistage cluster sampling method, we randomly selected enumeration areas, households, and individuals. One household member (aged 15-49 years) selected at random was invited for survey participation. After obtaining consent, questionnaires were administered to obtain sociodemographic, psychosocial, and behavioural information, and exposure to HIV prevention and treatment programmes. Clinical samples were collected for laboratory measurements. Statistical analyses were done accounting for multilevel sampling and weighted to represent the population. A multivariable logistic regression model assessed factors associated with HIV infection. FINDINGS Between June 11, 2014, and June 22, 2015, we enrolled 9812 individuals. The population-weighted HIV prevalence was 36·3% (95% CI 34·8-37·8, 3969 of 9812); 44·1% (42·3-45·9, 2955 of 6265) in women and 28·0% (25·9-30·1, 1014 of 3547) in men (p<0·0001). HIV prevalence in women aged 15-24 years was 22·3% (20·2-24·4, 567 of 2224) compared with 7·6% (6·0-9·3, 124 of 1472; p<0·0001) in men of the same age. Prevalence peaked at 66·4% (61·7-71·2, 517 of 760) in women aged 35-39 years and 59·6% (53·0-66·3, 183 of 320) in men aged 40-44 years. Consistent condom use in the last 12 months was 26·5% (24·1-28·8, 593 of 2356) in men and 22·7% (20·9-24·4, 994 of 4350) in women (p=0·0033); 35·7% (33·4-37·9, 1695 of 5447) of womens male partners and 31·9% (29·5-34·3, 1102 of 3547) of men were medically circumcised (p<0·0001), and 45·6% (42·9-48·2, 1251 of 2955) of women and 36·7% (32·3-41·2, 341 of 1014) of men reported antiretroviral therapy (ART) use (p=0·0003). HIV viral suppression was achieved in 54·8% (52·0-57·5, 1574 of 2955) of women and 41·9% (37·1-46·7, 401 of 1014) of men (p<0·0001), and 87·2% (84·6-89·8, 1086 of 1251) of women and 83·9% (78·5-89·3, 284 of 341; p=0·3670) of men on ART. Age, incomplete secondary schooling, being single, having more than one lifetime sex partner (women), sexually transmitted infections, and not being medically circumcised were associated with HIV-positive status. INTERPRETATION The HIV burden in specific age groups, the suboptimal differential coverage, and uptake of HIV prevention strategies justifies a location-based approach to surveillance with finer disaggregation by age and sex. Intensified and customised approaches to seek, identify, and link individuals to HIV services are crucial to achieving epidemic control in this community.
