In 2017, the Joint United Nations Programme on HIV/AIDS (UNAIDS) estimated that worldwide, 36.9 million persons were living with human immunodeficiency virus (HIV) infection, the virus infection that causes acquired immunodeficiency syndrome (AIDS). Among persons with HIV infection, approximately 75% were aware of their HIV status, leaving 9.4 million persons with undiagnosed infection (1). Index testing, also known as partner notification or contact tracing, is an effective case-finding strategy that targets the exposed contacts of HIV-positive persons for HIV testing services. This report summarizes data from HIV tests using index testing in 20 countries supported by CDC through the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) during October 1, 2016-March 31, 2018. During this 18-month period, 1,700,998 HIV tests with 99,201 (5.8%) positive results were reported using index testing. The positivity rate for index testing was 9.8% among persons aged ≥15 years and 1.5% among persons aged <15 years. During the reporting period, HIV positivity increased 64% among persons aged ≥15 years (from 7.6% to 12.5%) and 67% among persons aged <15 years (from 1.2% to 2.0%). Expanding index testing services could help increase the number of persons with HIV infection who know their status, are initiated onto antiretroviral treatment, and consequently reduce the number of persons who can transmit the virus.

In Botswana, 85% of persons living with HIV are aware of their status. We performed an economic analysis of HIV testing activities implemented during intensive campaigns, in 11 communities, between April 2015 and March 2016, through the Botswana Combination Prevention Project. The total cost was $1,098,312, or $99,847 per community, with 60% attributable to home-based testing and 40% attributable to mobile testing. The cost per person tested was $44, and $671 per person testing positive (2017 USD). Labor costs comprised 64% of total costs. In areas of high HIV prevalence and treatment coverage, the cost of untargeted home-based testing may be inflated by the efforts required to assess the testing eligibility of clients who are HIV-positive and on ART. Home-based and mobile testing delivered though an intensive community-based campaign allowed the identification of HIV positive persons, who may not access health facilities, at a cost comparable to other studies.

We examined trends in cross-sectional HIV prevalence (a surrogate for incidence) and past 12 month testing behavior among young men who have sex with men (MSM). The Young Men's Survey and the National HIV Behavioral Surveillance System conducted interviews and HIV testing among MSM recruited by venue-based sampling during 1994-2011. Using data from five cities, we determined whether interview year was associated with HIV prevalence and recent testing for MSM ages 18-22 and 23-29 years, after adjusting for city, race/ethnicity, and education. Multivariable analysis demonstrated an overall increase in prevalence among MSM ages 23-29 years, driven by an increase in Baltimore. There was no change in HIV prevalence among MSM ages 18-22 years overall, although prevalence increased in Baltimore. HIV testing increased significantly for both age groups. Gains in HIV testing are encouraging, but increasing prevalence among young MSM in Baltimore suggests increasing incidence and the need for additional efforts for this population.

The success of antiretroviral therapy (ART) requires continuous engagement in care and optimal levels of adherence to achieve sustained HIV viral suppression. We evaluated HIV-care cascade costs and outcomes of a community-based, mobile HIV-care, peer-delivered linkage case-management program (CommLink) implemented in Manzini region, Eswatini. Abstraction teams visited referral facilities during July 2019-April 2020 to locate, match, and abstract the clinical data of CommLink clients diagnosed between March 2016 and March 2018. An ingredients-based costing approach was used to assess economic costs associated with CommLink. The estimated total CommLink costs were $2 million. Personnel costs were the dominant component, followed by travel, commodities and supplies, and training. Costs per client tested positive were $499. Costs per client initiated on ART within 7, 30, and 90 days of diagnosis were $2114, $1634, and $1480, respectively. Costs per client initiated and retained on ART 6, 12, and 18 months after diagnosis were $2343, $2378, and $2462, respectively. CommLink outcomes and costs can help inform community-based HIV testing, linkage, and retention programs in other settings to strengthen effectiveness and improve efficiency.

BACKGROUND: Persons living with HIV infection (PLHIV) who are diagnosed in community settings in sub-Saharan Africa are particularly vulnerable to barriers to care that prevent or delay many from obtaining antiretroviral therapy (ART). METHODS: We conducted a retrospective cohort study to assess if a package of peer-delivered linkage case management and treatment navigation services (CommLink) was more effective than peer-delivered counseling, referral, and telephone follow-up (standard linkage services, SLS) in initiating and retaining PLHIV on ART after diagnosis in community settings in Eswatini. HIV-test records of 773 CommLink and 769 SLS clients aged ≥ 15 years diagnosed between March 2016 and March 2018, matched by urban and rural settings of diagnosis, were selected for the study. CommLink counselors recorded resolved and unresolved barriers to care (e.g., perceived wellbeing, fear of partner response, stigmatization) during a median of 52 days (interquartile range: 35-69) of case management. RESULTS: Twice as many CommLink than SLS clients initiated ART by 90 days of diagnosis overall (88.4% vs. 37.9%, adjusted relative risk (aRR): 2.33, 95% confidence interval (CI): 1.97, 2.77) and during test and treat when all PLHIV were eligible for ART (96.2% vs. 37.1%, aRR: 2.59, 95% CI: 2.20, 3.04). By 18 months of diagnosis, 54% more CommLink than SLS clients were initiated and retained on ART (76.3% vs. 49.5%, aRR: 1.54, 95% CI: 1.33, 1.79). Peer counselors helped resolve 896 (65%) of 1372 identified barriers of CommLink clients. Compared with clients with ≥ 3 unresolved barriers to care, 42% (aRR: 1.42, 95% CI: 1.19, 1.68) more clients with 1-2 unresolved barriers, 44% (aRR: 1.44, 95% CI: 1.25, 1.66) more clients with all barriers resolved, and 54% (aRR: 1.54, 95% CI: 1.30, 1.81) more clients who had no identified barriers were initiated and retained on ART by 18 months of diagnosis. CONCLUSIONS: To improve early ART initiation and retention among PLHIV diagnosed in community settings, HIV prevention programs should consider providing a package of peer-delivered linkage case management and treatment navigation services. Clients with multiple unresolved barriers to care measured as part of that package should be triaged for differentiated linkage and retention services.
ABSTRACT
INTRODUCTION: Hazardous alcohol use (HAU), defined as a pattern of alcohol consumption that increases the risk of harmful consequences for the user or others, is associated with an elevated risk of human immunodeficiency virus (HIV) infection and poor health outcomes. We describe the association between people living with HIV (PLHIV) who report HAU and key HIV indicators. Gaps in current literature in estimating HAU on HIV outcomes at the regional level of Eastern and Southern Africa still exist and our analysis aims to address this issue. METHODS: We used weighted pooled data (2015-2017) from the nationally representative Population-based HIV Impact Assessments among adults who provided written consent aged 18-59 years from Eswatini, Malawi, Namibia, Tanzania, Zambia and Zimbabwe. We estimated differences in the prevalence of HIV infection and The Joint United Nations Programme on HIV and AIDS (UNAIDS) 90-90-90 indicators between PLHIV by HAU status using log-binomial regression, stratified by sex. HAU was determined using the Alcohol Use Identification Test-Consumption. RESULTS: Among the 9755 women and 4444 men who tested HIV positive, 6.6% of women and 21.8% of men engaged in HAU. Women who reported HAU were more likely to be HIV positive (adjusted prevalence ratio [aPR] = 1.31, 95% CI: 1.18-1.46) compared to those who did not report HAU. For the UNAIDS 90-90-90 targets, women who engaged in HAU were more likely to be unaware of their HIV-positive status (aPR = 1.22, 95% CI: 1.01-1.47) and not on antiretroviral therapy (ART) (aPR = 1.73, 95% CI: 1.26-2.37). Men who engaged in HAU were more likely to be unaware of their HIV-positive status (aPR = 1.56, 95% CI 1.39-1.76) and not on ART (aPR = 1.72, 95% CI: 1.30-2.29). No difference in viral load suppression, defined as <1000 copies/ml of HIV RNA, was seen by sex. CONCLUSIONS: PLHIV who engage in HAU were more likely to have suboptimal outcomes along the HIV care continuum when compared to those who did not engage in HAU. Targeted interventions, such as alcohol screening for HAU in HIV testing and treatment settings and HIV prevention efforts in alcohol-based venues, may help countries reach HIV epidemic control by 2030.

BACKGROUND: Among men who have sex with men (MSM) in the United States, the influence of HIV/AIDS complacency and beliefs about the efficacy of highly active antiretroviral therapy (HAART) on HIV-infection risk is unknown. METHODS: We analyzed data from a 1998-2000 cross-sectional 6-city survey of 1575 MSM aged 23 to 29 years who had never tested for HIV or had last tested HIV-negative to assess these plausible influences overall and by race/ethnicity. FINDINGS: Measured as strong endorsement for reduced HIV/AIDS concern due to HAART, HIV/AIDS complacency was associated with reporting ≥10 male sex partners (odds ratio [OR], 2.94; 95% confidence interval [CI], 2.12-4.07), unprotected anal intercourse with an HIV-positive or HIV-unknown-status male partner (OR, 2.06; 95% CI, 1.51-2.81), and testing HIV-positive (adjusted OR [AOR], 2.35; 95% CI, 1.38-3.98). Strong endorsement of the belief that HAART mitigates HIV/AIDS severity was more prevalent among black (21.8%) and Hispanic (21.3%) than white (9.6%) MSM (P < 0.001), and was more strongly associated with testing HIV-positive among black (AOR, 4.65; 95% CI, 1.97-10.99) and Hispanic (AOR, 4.12; 95% CI, 1.58-10.70) than white (AOR, 1.62; 95% CI, 0.64-4.11) MSM. CONCLUSIONS: Young MSM who are complacent about HIV/AIDS because of HAART may be more likely to engage in risk behavior and acquire HIV. Programs that target HIV/AIDS complacency as a means to reduce HIV incidence among young MSM should consider that both the prevalence of strong HAART-efficacy beliefs and the effects of these beliefs on HIV-infection risk might differ considerably by race/ethnicity.

Despite considerable research, the causal relationship remains unclear between HIV/AIDS complacency, measured as reduced HIV/AIDS concern because of highly active antiretroviral therapy (HAART), and HIV risk behavior. Understanding the directionality and underpinnings of this relationship is critical for programs that target HIV/AIDS complacency as a means to reduce HIV incidence among men who have sex with men (MSM). This report uses structural equation modeling to evaluate a theory-based, HIV/AIDS complacency model on 1,593 MSM who participated in a venue-based, cross-sectional survey in six U.S. cities, 1998-2000. Demonstrating adequate fit and stability across geographic samples, the model explained 15.0% of the variance in HIV-acquisition behavior among young MSM. Analyses that evaluated alternative models and models stratified by perceived risk for HIV infection suggest that HIV/AIDS complacency increases acquisition behavior by mediating the effects of two underlying HAART-efficacy beliefs. New research is needed to assess model effects on current acquisition risk behavior, and thus help inform prevention programs designed to reduce HIV/AIDS complacency and HIV incidence among young MSM.

INTRODUCTION: The scale-up of Universal Test and Treat has resulted in reductions in HIV morbidity, mortality and incidence. However, healthcare system and personal challenges have impacted the levels of treatment coverage achieved. We implemented interventions to improve linkage to care, retention, viral load (VL) coverage and service delivery, and describe the HIV care cascade over the course of the Botswana Combination Prevention Project (BCPP) study. METHODS: BCPP was designed to evaluate the impact of prevention interventions on HIV incidence in 30 communities in Botswana. We followed a longitudinal cohort of newly identified and known HIV-positive persons not on antiretroviral therapy (ART) identified through community-based testing activities through BCPP and referred with appointments to local HIV clinics in 15 intervention communities. Those who did not keep the first or follow-up appointments were tracked and traced through phone and home contacts. Improvements to service delivery models in the intervention clinics were also implemented. RESULTS: A total of 3,657 newly identified or HIV-positive persons not on ART were identified and referred to their local HIV clinic; 90% (3,282/3,657) linked to care and of those, 93% (3,066/3,282) initiated treatment. Near the end of the study, 221 persons remained >90 days late for appointments or missing. Tracing efforts identified 54/3,066 (2%) persons who initiated treatment but died, and 106/3,066 (3%) persons were located and returned to treatment. At study end, 61/3,066 (2%) persons remained missing and were never reached. Overall, 2,951 (98%) persons living with HIV (PLHIV) who initiated treatment were still alive, retained in care and still receiving ART out of the 3,001 persons alive at the end of the study. Of those on ART, 2,854 (97%) had current VL results and 2,784 (98%) of those were virally suppressed at study end. CONCLUSIONS: This study achieved high rates of linkage, treatment initiation, retention and VL coverage and suppression in a cohort of newly identified and known PLHIV not on ART. Tracking and tracing interventions effectively identified those persons who needed more resource intensive follow-up. The interventions implemented to improve service delivery and data quality may have also contributed to high linkage and retention rates. Clinical trial number: NCT01965470.

BACKGROUND: Identifying men living with HIV in sub-Saharan Africa (SSA) is critical to end the epidemic. We describe the underlying factors of unawareness among men aged 15-59 years who ever tested for HIV in 13 SSA countries. METHODS: Using pooled data from the nationally representative Population-based HIV Impact Assessments, we fit a log-binomial regression model to identify characteristics related to HIV positivity among HIV-positive unaware and HIV-negative men ever tested for HIV. RESULTS: A total of 114,776 men were interviewed and tested for HIV; 4.4% were HIV-positive. Of those, 33.7% were unaware of their HIV-positive status, (range: 20.2%-58.7%, in Rwanda and Cote d'Ivoire). Most unaware men reported they had ever received an HIV test (63.0%). Age, region, marital status, and education were significantly associated with HIV positivity. Men who had HIV-positive sexual partners (adjusted prevalence ratio [aPR]: 5.73; confidence interval [95% CI]: 4.13 to 7.95) or sexual partners with unknown HIV status (aPR: 2.32; 95% CI: 1.89 to 2.84) were more likely to be HIV-positive unaware, as were men who tested more than 12 months compared with HIV-negative men who tested within 12 months before the interview (aPR: 1.58; 95% CI: 1.31 to 1.91). Tuberculosis diagnosis and not being circumcised were also associated with HIV positivity. CONCLUSION: Targeting subgroups of men at risk for infection who once tested negative could improve yield of testing programs. Interventions include improving partner testing, frequency of testing, outreach and educational strategies, and availability of HIV testing where men are accessing routine health services.

OBJECTIVE: Among HIV-infected persons, we evaluated use of client partner notification (CPN) and health-department partner notification strategies to inform sex partners of possible HIV exposure, and prior exposure to partner counseling and referral services. METHODS: We conducted a cross-sectional, observational study of 590 persons diagnosed with HIV in the prior 6 months at 51 HIV test, medical, and research providers in Chicago and Los Angeles in 2003 and 2004. Logistic regression was used to identify independent correlates of using CPN to notify all locatable partners. RESULTS: Participants reported a total of 5091 sex partners in the 6 months preceding HIV diagnosis; 1253 (24.6%) partners were locatable and not known to be HIV-positive. Of 439 participants with ≥1 locatable partners, 332 (75.6%) reported notifying 696 (55.5%) partners by CPN (585, 84.1%), health-department partner notification (94, 13.5%), or other means (17, 2.4%); 208 (47.4%) used CPN to notify all locatable partners. Independent correlates of CPN included having fewer locatable partners and discussing the need to notify partners with an HIV medical-care provider (black and Hispanic participants only). Many participants reported that their HIV test or medical-care provider did not discuss the need to notify partners (48.8%, 33.7%, respectively) and did not offer health-department partner-notification services (60.8%, 52.8%). CONCLUSION: Many locatable sex partners who might benefit from being notified of potential HIV exposure are not notified. In accordance with national policies, HIV test and medical-care providers should routinely provide partner counseling and referral services to HIV-infected clients so that all locatable partners are notified and provided an opportunity to learn their HIV status.

INTRODUCTION: HIV misdiagnosis leads to severe individual and public health consequences. Retesting for verification of all HIV-positive cases prior to antiretroviral therapy initiation can reduce HIV misdiagnosis, yet this practice has not been not widely implemented. METHODS: We evaluated and compared the cost of retesting for verification of HIV seropositivity (retesting) to the cost of antiretroviral treatment (ART) for misdiagnosed cases in the absence of retesting (no retesting), from the perspective of the health care system. We estimated the number of misdiagnosed cases based on a review of misdiagnosis rates, and the number of positives persons needing ART initiation by 2020. We presented the total and per person costs of retesting as compared to no retesting, over a ten-year horizon, across 50 countries in Africa grouped by income level. We conducted univariate sensitivity analysis on all model input parameters, and threshold analysis to evaluate the parameter values where the total costs of retesting and the costs no retesting are equivalent. Cost data were adjusted to 2017 United States Dollars. RESULTS AND DISCUSSION: The estimated number of misdiagnoses, in the absence of retesting was 156,117, 52,720 and 29,884 for lower-income countries (LICs), lower-middle income countries (LMICs), and upper middle-income countries (UMICs), respectively, totaling 240,463 for Africa. Under the retesting scenario, costs per person initially diagnosed were: $40, $21, and $42, for LICs, LMICs, and UMICs, respectively. When retesting for verification is implemented, the savings in unnecessary ART were $125, $43, and $75 per person initially diagnosed, for LICs, LMICs, and UMICs, respectively. Over the ten-year horizon, the total costs under the retesting scenario, over all country income levels, was $475 million, and was $1.192 billion under the no retesting scenario, representing total estimated savings of $717 million in HIV treatment costs averted. CONCLUSIONS: Results show that to reduce HIV misdiagnosis, countries in Africa should implement the WHO's recommendation of retesting for verification prior to ART initiation, as part of a comprehensive quality assurance program for HIV testing services.

INTRODUCTION: Non-citizens often face barriers to HIV care and treatment. Quantifying knowledge of positive HIV status and antiretroviral therapy (ART) coverage among non-citizens in a high HIV-prevalence country like Botswana that is close to achieving UNAIDS "90-90-90" targets may expose important gaps in achieving universal HIV testing and treatment. METHODS: The Botswana Combination Prevention Project (BCPP) is a pair-matched cluster-randomized trial evaluating the impact of prevention interventions on HIV incidence in 30 rural or peri-urban communities. Community case finding and HIV testing were conducted in home and mobile venues in 15 intervention communities from October 2013-September 2017. In this secondary analysis, we compared HIV positivity, knowledge of positive HIV-status, and ART status among all citizens and non-citizens assessed at intake in the intervention communities. RESULTS: HIV status was assessed in 57,556 residents in the intervention communities; 4% (n = 2,463) were non-citizens. Five communities accounted for 81% of the total non-citizens assessed. A lower proportion of non-citizens were HIV-positive (15%; n = 369) compared to citizens (21%; n = 11,416) [p = 0.026]; however, a larger proportion of non-citizens did not know their HIV-positive status prior to BCPP testing (75%) as compared to citizens (15%) [p = 0.003]. Among residents with knowledge of their HIV-positive status before BCPP, 79% of the non-citizens (72/91) were on ART compared to 86% (8,267/9,652) of citizens (p = 0.137). CONCLUSIONS: Although non-citizens were less likely to know their HIV-positive status compared to citizens, there were no differences in treatment uptake among non-citizens and citizens who knew their status. Designing interventions for non-citizens that provide HIV testing and treatment services commensurate to that of citizens as well as targeting communities with the largest number of non-citizens may help close a meaningful gap in the HIV care cascade and ensure ethical treatment for all HIV-positive persons. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01965470 (Botswana Combination Prevention Project).

INTRODUCTION: Achieving widespread knowledge of HIV-positive status is a crucial step to reaching universal ART coverage, population level viral suppression, and ultimately epidemic control. We implemented a multi-modality HIV testing approach to identify 90% or greater of HIV-positive persons in the Botswana Combination Prevention Project (BCPP) intervention communities. METHODS: BCPP is a cluster-randomized trial designed to evaluate the impact of combination prevention interventions on HIV incidence in 30 communities in Botswana. Community case finding and HIV testing that included home and targeted mobile testing were implemented in the 15 intervention communities. We described processes for identifying HIV-positive persons, uptake of HIV testing by age, gender and venue, characteristics of persons newly diagnosed through BCPP, and coverage of knowledge of status reached at the end of study. RESULTS: Of the 61,655 eligible adults assessed in home or mobile settings, 13,328 HIV-positive individuals, or 93% of the estimated 14,270 positive people in the communities were identified through BCPP. Knowledge of status increased by 25% over the course of the study with the greatest increases seen among men (37%) as compared to women (19%) and among youth aged 16-24 (77%) as compared to older age groups (21%). Although more men were tested through mobile than through home-based testing, higher rates of newly diagnosed HIV-positive men were found through home than mobile testing. CONCLUSIONS: Even when HIV testing coverage is high, additional gains can be made using a multi-modality HIV testing strategy to reach different sub-populations who are being missed by non-targeted program activities. Men and youth can be reached and will engage in community testing when services are brought to places they access routinely.

OBJECTIVES: We measured the prevalence of hepatitis B virus (HBV) immunization and HBV infection among men aged 23 to 29 years who have sex with men. METHODS: We analyzed data from 2834 men who have sex with men in 6 US metropolitan areas. Participants were interviewed and tested for serologic markers of immunization and HBV infection in 1998 through 2000. RESULTS: Immunization prevalence was 17.2%; coverage was 21.0% among participants with private physicians or health maintenance organizations and 12.6% among those with no source of health care. Overall, 20.6% had markers of HBV infection, ranging from 13.7% among the youngest to 31.0% among the oldest participants. Among those susceptible to HBV, 93.5% had regular sources of health care, had been tested for HIV, or had been treated for a sexually transmitted disease. CONCLUSIONS: Although many young men who have sex with men have access to health care, most are not immunized against HBV. To reduce morbidity from HBV in this population, providers of health care, including sexually transmitted disease and HIV prevention services, should provide vaccinations or referrals for vaccination.

Many children living with HIV in resource-limited settings remain undiagnosed and at risk for HIV-related mortality and morbidity. This article describes 5 key strategies for strengthening HIV case finding and linkage to treatment for infants, children, and adolescents. These strategies result from lessons learned during the Accelerating Children's HIV/AIDS Treatment Initiative, a public-private partnership between the President's Emergency Plan for AIDS Relief (PEPFAR) and the Children's Investment Fund Foundation (CIFF). The 5 strategies include (1) implementing a targeted mix of HIV case finding approaches (eg, provider-initiated testing and counseling within health facilities, optimization of early infant diagnosis, index family testing, and integration of HIV testing within key population and orphan and vulnerable children programs); (2) addressing the unique needs of adolescents; (3) collecting and using data for program improvement; (4) fostering a supportive political and community environment; and (5) investing in health system-strengthening activities. Continued advocacy and global investments are required to eliminate AIDS-related deaths among children and adolescents.

OBJECTIVE: To evaluate the proportion of new sexual partners potentially exposed to HIV from young MSM who disclosed being HIV-negative. DESIGN: Cross-sectional, observational study of men aged 23-29 years recruited from randomly sampled MSM-identified venues in six US cities. METHODS: Participants were interviewed and tested for HIV. Analyses were restricted to MSM who reported last testing HIV-negative and having one or more new partners in the prior 6 months. RESULTS: Of 1701 MSM who reported a total of 11 793 new partners, 1075 (63%) disclosed being HIV-negative to 4253 (36%) new partners before having sex with them for the first time. Of disclosers, 352 (33%) reported last testing HIV-negative > 1 year before their interview and 80 (7%) tested HIV-positive (HIV-infected unaware). By race, 24% of black, 5% of Hispanic, and 3% of white disclosers tested HIV-positive. Of the 4253 new partners, 296 (7%) were partners of the 80 HIV-infected unaware MSM. By race, 22% of new partners of black, 3% of new partners of Hispanic, and 4% of new partners of white MSM, were partners of HIV-infected unaware MSM who disclosed being HIV-negative. CONCLUSIONS: Many new sex partners may be unintentionally exposed to HIV from young MSM, particularly those who are black and who disclose being HIV-negative based on an earlier test. Young MSM should test for HIV more frequently and consistently use condoms with all partners unless they are in a mutually monogamous relationship in which both partners have tested HIV-negative at least 3 months since their last potential HIV exposure.

In 2008, HIV rapid testing (HIV RT) was only minimally used in the Caribbean region. Collaboration with countries and international partners since then has resulted in greater availability and use of HIV RT services. Surveys were conducted in 2012 and 2014 among 11 selected Caribbean countries to inform stakeholders of progress made since 2008 and to identify strategies to further improve access and uptake of high-quality HIV RT in community- and facility-based settings in support of the UNAIDS 90-90-90 targets. Key accomplishments during this period include (1) presence of in-country national HIV RT algorithms, (2) use of the dried tube specimen (DTS) as an external quality assessment (EQA) program, (3) use of standardized logbooks for data collection and monitoring, and (4) use of oral fluid for HIV RT, particularly for key population surveys. Although progress has been made since 2008 to increase access and improve the quality of HIV RT among countries in the Caribbean, some work remains to be done. This includes the development of new policies and implementation of existing ones, task shifting, quality and access to testing, testing strategies, and integration of HIV RT into HIV Testing Services.

The HIV epidemic is rising in Asian and Pacific Islander men who have sex with men (API MSM), who are often first diagnosed with HIV at a late stage of disease. We investigated the HIV testing patterns, correlates of prior testing, and awareness of HIV infection of 495 API MSM aged 18-29 years recruited from venues in San Francisco, using standardized face-to-face interviews. One quarter of participants had never tested for HIV, citing reasons such as perceived low risk, fear of results, and fear of needles. Older age, gay sexual orientation, history of sexually transmitted disease, higher lifetime number of sexual partners, and higher acculturation were significantly and independently associated with prior testing. Thirteen (2.6%) tested HIV-positive, of whom eight were unaware of their infection, five perceived themselves to be at low risk for HIV, and five reported recent UAI. These findings underscore the need to increase access to culturally appropriate and targeted HIV testing and to change perceptions of risk in this population.
