Enrollment in HIV Care Two Years after HIV Diagnosis in the Kingdom of Swaziland: An Evaluation of a National Program of New Linkage Procedures.

To improve early enrollment in HIV care, the Swaziland Ministry of Health implemented new linkage procedures for persons HIV diagnosed during the Soka Uncobe male circumcision campaign (SOKA, 2011-2012) and the Swaziland HIV Incidence Measurement Survey (SHIMS, 2011). Abstraction of clinical records and telephone interviews of a retrospective cohort of HIV-diagnosed SOKA and SHIMS clients were conducted in 2013-2014 to evaluate compliance with new linkage procedures and enrollment in HIV care at 92 facilities throughout Swaziland. Of 1,105 clients evaluated, within 3, 12, and 24 months of diagnosis, an estimated 14.0%, 24.3%, and 37.0% enrolled in HIV care, respectively, after adjusting for lost to follow-up and non-response. Kaplan-Meier functions indicated lower enrollment probability among clients 14-24 (P = 0.0001) and 25-29 (P = 0.001) years of age compared with clients >35 years of age. At 69 facilities to which clients were referred for HIV care, compliance with new linkage procedures was low: referral forms were located for less than half (46.8%) of the clients, and few (9.6%) were recorded in the appointment register or called either before (0.3%) or after (4.9%) their appointment. Of over one thousand clients newly HIV diagnosed in Swaziland in 2011 and 2012, few received linkage services in accordance with national procedures and most had not enrolled in HIV care two years after their diagnosis. Our findings are a call to action to improve linkage services and early enrollment in HIV care in Swaziland.

Seroprevalence and correlates of hepatitis a among HIV-negative American men who have sex with men.

BACKGROUND: Hepatitis A outbreaks are well documented among men who have sex with men (MSM). This analysis examines characteristics associated with hepatitis A virus (HAV) infection among a large group of young adult MSM from five USA cities. METHODS: The Young Men's Survey was a cross-sectional prevalence study of HIV infection and related behavioural risk factors among MSM aged 15-29 years during 1994-2000. Serum specimens from HIV-negative participants were retrospectively tested for antibodies to HAV (anti-HAV). Data were stratified by ethnicity and analysed with logistic regression. RESULTS: Overall anti-HAV prevalence was 18.4% among the 2708 participants, and varied by ethnicity from 6.9 to 45.3% and was highest among Hispanic and Asian men (P < 0.001). Prevalence increased with age across all racial/ethnic groups. Among white men, anti-HAV positivity was associated with having 20 or more lifetime male sex partners for those aged 15-22 years (adjusted odds ratio (AOR)=2.1, 95% confidence interval (CI)=1.0-4.1) and ever having had unprotected anal sex for those aged 23-29 years (AOR=2.4, 95% CI=1.2-4.5). CONCLUSIONS: Factors associated with a history of HAV infection among MSM in non-outbreak settings are probably similar to those among non-MSM. MSM are still at risk for HAV infection as a result of outbreaks occurring in MSM communities. Additional studies of hepatitis A vaccination coverage are needed to determine if strategies to vaccinate MSM are adequate.

HIV/AIDS complacency and HIV infection among young men who have sex with men, and the race-specific influence of underlying HAART beliefs.

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.

A plausible causal model of HAART-efficacy beliefs, HIV/AIDS complacency, and HIV-acquisition risk behavior among young men who have sex with men.

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.

Reasons for not HIV testing, testing intentions, and potential use of an over-the-counter rapid HIV test in an internet sample of men who have sex with men who have never tested for HIV.

BACKGROUND: Correlates of main reasons for not HIV testing, HIV testing intentions, and potential use of an over-the-counter rapid HIV test (OTCRT) among men who have sex with men who have never tested for HIV (NTMSM) are unknown. METHODS: We evaluated these correlates among 946 NTMSM from 6 US cities who participated in an internet-based survey in 2007. FINDINGS: Main reasons for not testing were low perceived risk (32.2%), structural barriers (25.1%), and fear of testing positive (18.1%). Low perceived risk was associated with having fewer unprotected anal intercourse (UAI) partners and less frequent use of the internet for HIV information; structural barriers were associated with younger age and more UAI partners; fear of testing positive was associated with black and Hispanic race/ethnicity, more UAI partners, and more frequent use of the internet for HIV information. Strong testing intentions were held by 25.9% of all NTMSM and 14.8% of those who did not test because of low perceived risk. Among NTMSM who were somewhat unlikely, somewhat likely, and very likely to test for HIV, 47.4%, 76.5%, and 85.6% would likely use an OTCRT if it was available, respectively. CONCLUSIONS: Among NTMSM who use the internet, main reasons for not testing for HIV vary considerably by age, race/ethnicity, UAI, and use of the internet for HIV information. To facilitate HIV testing of NTMSM, programs should expand interventions and services tailored to address this variation. If approved, OTCRT might be used by many NTMSM who might not otherwise test for HIV.

Prevalence of HIV infection and prior HIV testing among young men who have sex with men. The Baltimore young men's survey.

Data are presented from the Baltimore Young Men's Survey, a cross-sectional, venue-based sample survey of risks associated with HIV and report of a prior HIV test, conducted between 1996 and 2000, and enrolling 843 young men who have sex with men (MSM) aged 15-29 years. HIV prevalence was 12.1% overall and racial disparities in HIV prevalence were pronounced (range, 2.9% among non-Hispanic whites to 27.1% among non-Hispanic blacks). Risks independently associated with being HIV-positive were: being between 26 and 29 years of age, being non-Hispanic black or of other/mixed race, having had 20 or more lifetime male sex partners, having been diagnosed with a sexually transmitted disease (STD), and not being currently enrolled in school. The majority of participants (78.9%) reported a prior HIV test. In multivariate analysis, being older, having had five or more lifetime male sex partners, having had anal intercourse with males, reporting an STD diagnosis, and reporting recent unprotected anal sex were associated with report of a prior HIV test. Prevention efforts must address high HIV prevalence among young non-Hispanic black MSM and must make testing and effective counseling for young MSM readily available.

Rapid human immunodeficiency virus test quality assurance practices and outcomes among testing sites affiliated with 17 public health departments.

Rapid human immunodeficiency virus testing is often conducted in nonclinical settings by staff with limited training, so quality assurance (QA) monitoring is critical to ensure accuracy of test results. Rapid tests (n = 86,749) were generally conducted according to manufacturers' instructions, but ongoing testing competency assessments and on-site QA monitoring were not uniformly conducted.

Using arrest charge to screen for undiagnosed HIV infection among new arrestees: a study in Los Angeles County.

Despite high documented HIV prevalence, few jail systems offer universal HIV screening, nor is this always feasible. The authors evaluated undiagnosed HIV infection and HIV risk history by arrest charge among 1,322 new arrestees to examine whether specific charges may help prioritize jail-based screening. Undiagnosed HIV prevalence was 2.7% and 1.0% among males and females, with 32% and 45% reporting recent STD diagnoses or high-risk behaviors for HIV. HIV risk history distinguished HIV-infected males but not females. Males with parole violation, sex, or theft charges had high undiagnosed HIV infection rates relative to other males. A weaker trend was observed for females with parole violation, drug, or violent charges. These charges represented 30% and 66% of males and females studied and 56% and 100% of their undiagnosed HIV infections, respectively. Using arrest charge to target screening may efficiently increase HIV diagnosis in jail inmates where universal HIV screening is not possible.

Exposure to HIV partner counseling and referral services and notification of sexual partners among persons recently diagnosed with HIV.

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.

HIV prevention services received at health care and HIV test providers by young men who have sex with men: an examination of racial disparities.

We investigated whether there were racial/ethnic differences among young men who have sex with men (MSM) in their use of, perceived importance of, receipt of, and satisfaction with HIV prevention services received at health care providers (HCP) and HIV test providers (HTP) that explain racial disparities in HIV prevalence. Young men, aged 23 to 29 years, were interviewed and tested for HIV at randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted to five U.S. cities that enrolled 50 or more black or Hispanic MSM. Among the 2,424 MSM enrolled, 1,522 (63%) reported using a HCP, and 1,268 (52%) reported having had an HIV test in the year prior to our interview. No racial/ethnic differences were found in using a HCP or testing for HIV. Compared with white MSM, black and Hispanic MSM were more likely to believe that HIV prevention services are important [respectively, AOR, 95% confidence interval (CI): 3.0, 1.97 to 4.51 and AOR, 95% CI: 2.7, 1.89 to 3.79], and were more likely to receive prevention services at their HCP (AOR, 95% CI: 2.5, 1.72 to 3.71 and AOR, 95% CI: 1.7, 1.18 to 2.41) and as likely to receive counseling services at their HTP. Blacks were more likely to be satisfied with the prevention services received at their HCP (AOR, 95% CI: 1.7, 1.14 to 2.65). Compared to white MSM, black and Hispanic MSM had equal or greater use of, perceived importance of, receipt of, and satisfaction with HIV prevention services. Differential experience with HIV prevention services does not explain the higher HIV prevalence among black and Hispanic MSM.

HIV risk factors reported by two samples of male bathhouse attendees in Los Angeles, California, 2001-2002.

BACKGROUND: We aimed to describe the use of voluntary HIV counseling and testing services, risk behaviors, and risk factors for unprotected anal sex (UAS) among men who have sex with men (MSM) who attended a bathhouse in Los Angeles during 2001-2002. METHODS: Using 2 cross-sectional study samples, we compared (in order below) 458 of 640 MSM who used voluntary HIV counseling and testing in the bathhouse with 398 MSM surveyed upon exit. Within each group, logistic regression identified factors associated with UAS at their most recent bathhouse visit. RESULTS: Of 640 MSM, 71 (11%) tested HIV-positive for the first time. Of the 50 HIV-positive MSM who completed a survey, 50% tested because of the convenient services. Similar proportions of MSM in both survey samples reported UAS (7%-8%) during their recent bathhouse visit. Risk factors associated with UAS in both survey samples were UAS with men outside the bathhouse and greater numbers of partners within the bathhouse. CONCLUSIONS: Comprehensive prevention services provided within bathhouses may reduce undiagnosed HIV infections among MSM, and targeting HIV prevention at the bathhouse may reduce risks with partners both inside and outside the bathhouse.

The Young Men's Survey phase II: hepatitis B immunization and infection among young men who have sex with men.

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.

Repeat confirmatory testing for persons with discordant whole blood and oral fluid rapid HIV test results: findings from post marketing surveillance.

BACKGROUND: Reactive oral fluid and whole blood rapid HIV tests must be followed with a confirmatory test (Western blot (WB), immunofluorescent assay (IFA) or approved nucleic acid amplification test (NAAT)). When the confirmatory result is negative or indeterminate (i.e. discordant with rapid result), repeat confirmatory testing should be conducted using a follow-up specimen. Previous reports have not described whether repeat testing adequately resolves the HIV-infection status of persons with discordant results. METHODOLOGY: Post-marketing surveillance was conducted in 368 testing sites affiliated with 14 state and 2 city health departments from August 11, 2004 to June 30, 2005 and one health department through December 31, 2005. For persons with discordant results, data were collected on demographics, risk behaviors, HIV test results and specimen types. Persons with repeat confirmatory results were classified as HIV-infected or uninfected. Regression models were created to assess risk factors for not having repeat testing. PRINCIPAL FINDINGS: Of 167,371 rapid tests conducted, 2589 (1.6%) were reactive: of these, 2417 (93%) had positive WB/IFA, 172 (7%) had negative or indeterminate WB/IFA. Of 89/172 (52%) persons with a repeat confirmatory test: 17 (19%) were HIV-infected, including 3 with indeterminate WB and positive NAAT; 72 (81%) were uninfected, including 12 with repeat indeterminate WB. Factors associated with HIV-infection included having an initial indeterminate WB/IFA (vs. negative) (p<0.001) and having an initial oral fluid WB (vs. serum) (p<0.001). Persons who had male-female sex (vs. male-male sex) were at increased risk for not having a repeat test [adjusted OR 2.6, 95% CI (1.3, 4.9)]. CONCLUSIONS: Though only half of persons with discordant results had repeat confirmatory testing, of those who did, nearly one in five were HIV-infected. These findings underscore the need for rapid HIV testing programs to increase repeat confirmatory testing for persons with discordant results. Because of the lower sensitivity of oral fluid WBs, confirmatory testing following a reactive rapid test should be conducted using serum or plasma, when possible.

Racial disparities in HIV incidence among young men who have sex with men: the Baltimore Young Men's Survey.

Recent reports have demonstrated racial disparities in the prevalence of HIV infection among men who have sex with men (MSM). The objectives of this study are to investigate whether racial disparities exist in HIV incidence among young MSM in Baltimore, MD and to examine potential explanations for differences. Data were collected by the Baltimore Young Men's Survey, a cross-sectional venue-based survey (1996 to 2000) enrolling MSM aged 15 to 29 years. HIV incidence was ascertained using the serologic testing algorithm for recent HIV seroconversion. HIV incidence was 4.2% per year (95% confidence interval [CI]: 1.2 to 10.5) among 843 participants. There were substantial racial differences in HIV incidence, ranging from 0 among Hispanics to 11.0% per year (95% CI: 5.5 to 19.7) among non-Hispanic blacks. In multivariate analysis, among MSM at risk for HIV acquisition, race was not associated with unprotected anal intercourse. Independent risks included having more than 4 recent male sexual partners (adjusted odds ratio [AOR] = 1.6, 95% CI: 1.0 to 2.4) and being under the influence of drugs while having sex (AOR = 1.6, 95% CI: 1.1 to 2.3). Non-Hispanic blacks were no more likely than non-Hispanic whites to report these risk behaviors. Possible alternative explanations for the observed racial disparities in HIV incidence and implications for prevention are explored.

Surveillance of HIV risk and prevention behaviors of men who have sex with men--a national application of venue-based, time-space sampling.

In collaboration with the Centers for Disease Control and Prevention, participating state and local health departments, universities, and community-based organizations applied venue-based, time-space sampling methods for the first wave of National HIV Behavioral Surveillance of men who have sex with men (NHBS-MSM). Conducted in 17 metropolitan areas in the United States and Puerto Rico from November 2003 through April 2005, NHBS-MSM methods included: (1) formative research to learn the venues, times, and methods to recruit MSM; (2) monthly sampling frames of eligible venues and day-time periods that met attendance, logistical, and safety criteria; and (3) recruitment of participants in accordance with randomly generated venue calendars. Participants were interviewed on HIV risk and prevention behaviors, referred to care when needed, and compensated for their time. By identifying the prevalence and trends of HIV risk and prevention behaviors, NHBS-MSM data may be used at local, state, and federal levels to help obtain, direct, and evaluate HIV prevention resources for MSM.

Investigation of false positive results with an oral fluid rapid HIV-1/2 antibody test.

BACKGROUND: In March 2004, the OraQuick rapid HIV antibody test became the first rapid HIV test approved by the US Food and Drug Administration for use on oral fluid specimens. Test results are available in 20 minutes, and the oral fluid test is non-invasive. From August 2004-June 2005, we investigated a sudden increase in false-positive results occurring in a performance study of OraQuick oral-fluid rapid HIV tests in Minnesota. METHODOLOGY/PRINCIPAL FINDINGS: In a field investigation, we reviewed performance study data on oral-fluid and whole-blood OraQuick rapid HIV test device lots and expiration dates and assessed test performance and interpretation with oral-fluid and whole-blood specimens by operators who reported false-positive results. We used multivariate logistic regression to evaluate client demographic and risk characteristics associated with false-positive results. Next, we conducted an incidence study of false-positive OraQuick rapid HIV tests in nine US cities and tested both oral-fluid and finger-stick whole-blood specimens from clients; reactive tests were confirmed with Western blot. Sixteen (4.1%) false-positive oral-fluid results occurred in the performance study from April 15, 2004 through August 31, 2004 with unexpired devices from six test lots among 388 HIV-uninfected clients (specificity, 95.9%; 95% CI: 93.4-97.6). Three test operators who had reported false-positive results performed and interpreted the test according to package-insert instructions. In multivariate analysis, only older age was significantly associated with false-positive results (adjusted odds ratio = 4.5, 95% CI: 1.2-25.7). In the incidence study, all valid oral-fluid and whole-blood results from 2,268 clients were concordant and no false-positive results occurred (100% specificity). CONCLUSIONS/SIGNIFICANCE: The field investigation did not identify a cause for the increase in false-positive oral-fluid results, and the incidence study detected no false-positive results. The findings suggest this was an isolated cluster; the test's overall performance was as specified by the manufacturer.

Perceptions of lifetime risk and actual risk for acquiring HIV among young men who have sex with men.

Among young men who have sex with men (MSM) surveyed in six US cities, we evaluated the magnitude and correlates of perceived lifetime risk for acquiring HIV, and missed opportunities to increase risk perception by providers of health-care and HIV-testing services. Overall, approximately one quarter of young MSM perceived themselves at moderate/high risk for acquiring HIV. Adjusting for demographic, prior testing, and behavioral characteristics, moderate/high perceived risk had the strongest association with unrecognized HIV infection. However, half of the 267 young MSM with unrecognized infection perceived themselves at low lifetime risk for acquiring HIV, and many young MSM with low-risk perception reported considerable risk behaviors. Providers of health-care and HIV-testing services missed opportunities to assess risks and recommend testing for young MSM. To increase HIV testing, prevention providers should intensify efforts to assess, and to increase when needed, perceptions of lifetime risks for acquiring HIV among young MSM.

Unintentional HIV exposures from young men who have sex with men who disclose being HIV-negative.

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.

Post-marketing surveillance of OraQuick whole blood and oral fluid rapid HIV testing.

OBJECTIVE: Post-marketing surveillance was conducted to monitor the performance of the OraQuick Advance rapid HIV-1/2 antibody test (OraQuick) on whole blood and oral fluid. DESIGN: Surveillance of routinely collected data on clients tested with OraQuick in 368 testing sites affiliated with 17 state and city health departments between 11 August 2004 and 30 June 2005. METHODS: For whole blood and oral fluid, we report the median (range) health department OraQuick specificity and positive predictive value (PPV), and the number of clients with discordant results (e.g. who had a reactive rapid test not confirmed positive by Western blot or indirect immunofluorescence). At one site with lower than expected oral-fluid specificity, we evaluated whether device expiration, manufacturing lot, operator practices, or device-storage or testing-area temperatures were associated with false-positive tests. RESULTS: During the surveillance period, 135 724 whole blood and 26 066 oral fluid rapid tests were conducted. The median health department whole blood OraQuick specificity was 99.98% (range: 99.73-100%) and PPV was 99.24% (range: 66.67-100%); the median oral fluid specificity was 99.89% (range: 99.44-100%) and PPV was 90.00% (range: 50.00-100%). A total of 124 discordant results were reported from 68 (0.05%) whole blood and 56 (0.22%) oral fluid rapid tests. The oral fluid specificity at the site with excess oral fluid false-positive tests was 98.7% (95% confidence interval: 98.18-99.11%). The increase in false-positive tests at that site was not associated with any specific device characteristic, operator procedure or temperature condition. CONCLUSION: The specificity of OraQuick performed on whole blood and oral fluid during post-marketing surveillance was compatible with the manufacturer's claim within the package insert. However, one site experienced lower than expected oral fluid specificity. Sites that observe that the specificity of OraQuick is lower than the range indicated in the package insert should notify the manufacturer and evaluate quality assurance procedures.

Recent HIV testing among young men who have sex with men: correlates, contexts, and HIV seroconversion.

OBJECTIVES: We evaluated the correlates and contexts of HIV testing within the past year, subsequent risk reduction, and HIV seroconversion among young men who have sex with men (MSM). METHODS: Young men aged 23 to 29 years were approached, interviewed, counseled, and tested for HIV at 181 randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted to 2,797 MSM who reported never testing HIV-positive. RESULTS: Of the 2,797 MSM, 1,281 (46%) either never previously tested or had not tested in the past year (never/remote testers); 1,516 (54%) had tested in the past year (recent testers); and 271 (10%) tested HIV-positive as part of the study. Of 1,885 recent sex partners reported by HIV-infected participants, 68% were partners of never/remote testers. Of recent testers, 50% tested anonymously, 51% tested because of specific risks, 59% were counseled, 47% reported reducing their risks after testing, and 8% tested HIV-positive (percent HIV-infected by race: blacks, 24%; Hispanics, 6%; whites, 4%; Asians, 1%). CONCLUSION: Nearly half of young MSM participants had not tested in the past year and HIV-infected never/remote testers accounted for approximately two thirds of recent partners potentially exposed to HIV. Of those who had tested recently, many MSM, especially those who are black, had already acquired HIV. To reduce HIV transmission and facilitate early diagnosis and entry into care, increased HIV testing among young at-risk MSM in the United States, especially those who are black, is needed.
