Findings from the first year of a federally funded, direct-to-consumer HIV self-test distribution program - United States, March 2023-March 2024
Sanchez T , MacGowan RJ , Hecht J , Keralis JM , Ackah-Toffey L , Bourbeau A , Dana R , Lilo EA , Downey RS , Getachew-Smith H , Hannah M , Valencia R , Krebs E , Pingel ES , Gayden JJ , Norelli J , Mason Z , Mahn J , Cramer N , Bole R , Sullivan P , Nwaohiri AN , Stryker JE , Kourtis AP , DiNenno EA , Fanfair RN , Mermin JH , Delaney KP . MMWR Morb Mortal Wkly Rep 2024 73 (24) 558-564 In September 2022, CDC funded a nationwide program, Together TakeMeHome (TTMH), to expand distribution of HIV self-tests (HIVSTs) directly to consumers by mail through an online ordering portal. To publicize the availability of HIVSTs to priority audiences, particularly those disproportionately affected by HIV, CDC promoted this program through established partnerships and tailored resources from its Let's Stop HIV Together social marketing campaign. The online portal launched March 14, 2023, and through March 13, 2024, distributed 443,813 tests to 219,360 persons. Among 169,623 persons who answered at least one question on a postorder questionnaire, 67.9% of respondents were from priority audiences, 24.1% had never previously received testing for HIV, and 24.8% had not received testing in the past year. Among the subset of participants who initiated a follow-up survey, 88.3% used an HIVST themselves, 27.1% gave away an HIVST, 11.7% accessed additional preventive services, and 1.9% reported a new positive HIVST result. Mailed HIVST distribution can quickly reach large numbers of persons who have never received testing for HIV or have not received testing as often as is recommended. TTMH can help to achieve the goal of diagnosing HIV as early as possible and provides a path to other HIV prevention and care services. Clinicians, community organizations, and public health officials should be aware of HIVST programs, initiate discussions about HIV testing conducted outside their clinics or offices, and initiate follow-up services for persons who report a positive or negative HIVST result. |
The testing imperative: Why the US ending the human immunodeficiency virus (HIV) epidemic program needs to renew efforts to expand HIV testing in clinical and community-based settings
Nosyk B , Fojo AT , Kasaie P , Enns B , Trigg L , Piske M , Hutchinson AB , DiNenno EA , Zang X , Del Rio C . Clin Infect Dis 2023 76 (12) 2206-2208 Data from several modeling studies demonstrate that large-scale increases in human immunodeficiency virus (HIV) testing across settings with a high burden of HIV may produce the largest incidence reductions to support the US Ending the HIV Epidemic (EHE) initiative's goal of reducing new HIV infections 90% by 2030. Despite US Centers for Disease Control and Prevention's recommendations for routine HIV screening within clinical settings and at least yearly screening for individuals most at risk of acquiring HIV, fewer than half of US adults report ever receiving an HIV test. Furthermore, total domestic funding for HIV prevention has remained unchanged between 2013 and 2019. The authors describe the evidence supporting the value of expanded HIV testing, identify challenges in implementation, and present recommendations to address these barriers through approaches at local and federal levels to reach EHE targets. |
HIV Testing Services Outcomes in CDC-Funded Health Departments During COVID-19.
Patel D , Williams WO , Wright C , Taylor-Aidoo N , Song W , Marandet A , DiNenno EA . J Acquir Immune Defic Syndr 2022 91 (2) 117-121 BACKGROUND: Organizations offering HIV prevention services have reported interruptions during the COVID-19 pandemic. The national extent of these interruptions and their public health impact remain largely unexplored. METHODS: Using data from 60 state and local health departments, we compared HIV testing services outcomes in calendar years 2019 and 2020, including the number of Centers for Disease Control and Prevention (CDC)-funded HIV tests conducted, the percentage of persons with newly diagnosed HIV infection (ie, HIV positivity), and the percentage linked to HIV medical care within 30 days after new diagnoses (ie, linkage to care) using χ2 and robust Poisson models. We also assessed the independent associations between the pandemic period (ie, March-December 2020) and the number of COVID-19 cases with monthly HIV testing services outcomes using multivariable robust Poisson models. RESULTS: There was a 46.0% (P < 0.001) reduction in the number of CDC-funded HIV tests conducted in 2020 (n = 1,255,895) compared with 2019 (n = 2,324,421). Although there were fewer persons with newly diagnosed HIV in 2020 (n = 5581 vs. n = 7739 in 2019), HIV positivity was greater in 2020 (0.4% vs. 0.3% in 2019; adjusted prevalence ratio [aPR] = 1.33, 95% confidence interval [CI]: 1.05 to 1.69). When adjusting for the monthly number of COVID-19 cases, the pandemic period was associated with a 56% reduction in the number of monthly CDC-funded HIV tests (adjusted rate ratio = 0.44, 95% CI: 0.37 to 0.52) but 28% higher monthly HIV positivity (aPR = 1.28 95% CI: 1.16 to 1.41) and 10% higher linkage to care (aPR = 1.10, 95% CI: 1.02 to 1.18). DISCUSSION: Despite increased HIV positivity, a drastic reduction in the number of CDC-funded HIV tests was observed in 2020, affecting the ability to identify persons with newly diagnosed HIV. CDC and health departments will need to expand testing strategies to cover tests not conducted in 2020 while adapting to the continuing pandemic.A visual abstract is available for this article at: http://links.lww.com/QAI/B941. |
Strategies adopted by gay, bisexual, and other men who have sex with men to prevent Monkeypox virus transmission - United States, August 2022
Delaney KP , Sanchez T , Hannah M , Edwards OW , Carpino T , Agnew-Brune C , Renfro K , Kachur R , Carnes N , DiNenno EA , Lansky A , Ethier K , Sullivan P , Baral S , Oster AM . MMWR Morb Mortal Wkly Rep 2022 71 (35) 1126-30 What is already known about this topic? A global monkeypox outbreak is currently primarily affecting gay, bisexual, and other men who have sex with men. What is added by this report? In a recent survey of gay, bisexual, and other men who have sex with men, approximately one half reported reducing their number of sex partners, one-time sexual encounters, and use of dating apps because of the monkeypox outbreak. Receipt of vaccine to protect against monkeypox varied by race, ethnicity, and geography. What are the implications for public health practice? It is essential that public health programs continue to deliver tailored, respectful harm reduction messages that do not create stigma to diverse communities of men who have sex with men. Vaccine programs should prioritize efforts to maximize equitable access. © 2022 Department of Health and Human Services. All rights reserved. |
HIV Testing Before and During the COVID-19 Pandemic - United States, 2019-2020.
DiNenno EA , Delaney KP , Pitasi MA , MacGowan R , Miles G , Dailey A , Courtenay-Quirk C , Byrd K , Thomas D , Brooks JT , Daskalakis D , Collins N . MMWR Morb Mortal Wkly Rep 2022 71 (25) 820-824 HIV testing is a core strategy for the Ending the HIV Epidemic in the U.S. (EHE) initiative, which has the aim of reducing new HIV infections by at least 90% by 2030.* During 2016-2017, jurisdictions with the highest HIV diagnosis rates were those with higher prevalences of HIV testing; past-year HIV testing was higher among persons who reported recent HIV risk behaviors compared with those who did not report these risks (1). During 2020-2021, the COVID-19 pandemic disrupted health care delivery, including HIV testing in part because many persons avoided services to comply with COVID-19 risk mitigation efforts (2). In addition, public health departments redirected some sexual health services to COVID-19-related activities.(†) CDC analyzed data from four national data collection systems to assess the numbers of HIV tests performed and HIV infections diagnosed in the United States in the years before (2019) and during (2020) the COVID-19 pandemic. In 2020, HIV diagnoses reported to CDC decreased by 17% compared with those reported in 2019. This decrease was preceded by decreases in HIV testing during the same period, particularly among priority populations including Black or African American (Black) gay men, Hispanic or Latino (Hispanic) gay men, bisexual men, other men who have sex with men (MSM), and transgender persons in CDC-funded jurisdictions. To compensate for testing and diagnoses missed during the COVID-19 pandemic and to accelerate the EHE initiative, CDC encourages partnerships among federal organizations, state and local health departments, community-based organizations, and health care systems to increase access to HIV testing services, including strategies such as self-testing and routine opt-out screening in health care settings. |
HIV Testing Strategies for Health Departments to End the Epidemic in the U.S
Delaney KP , DiNenno EA . Am J Prev Med 2021 61 S6-s15 An important goal of the Ending the HIV Epidemic in the U.S. initiative is the timely diagnosis of all people with HIV as early as possible after infection. To end the HIV epidemic, health departments were encouraged to propose new and innovative HIV testing strategies and improve the reach of existing programs. These activities were divided into 3 core strategies: expansion of routine screening in healthcare settings, locally tailored HIV testing initiatives in nonhealthcare settings, and specific efforts to increase the frequency of testing for individuals with increased potential for acquiring HIV. Because HIV testing is such a crucial part of the core activities of the Centers for Disease Control and Prevention's HIV prevention programs, there are many examples of evidence-based programs and best practices for HIV testing in both clinical and nonclinical settings. This article reviews the evidence base for these strategies and some of the activities proposed under the Diagnose pillar to achieve the goal of diagnosing all HIV infections as early as possible. All other Ending the HIV Epidemic in the U.S. activities start with an awareness of HIV status, which is actually the indicator for which most health departments are closest to the proposed targets. There are both proven and emerging approaches to increasing HIV screening and increasing the frequency of HIV screening available. The Ending the HIV Epidemic in the U.S. initiative provides the motivation, the resources, and a coordinated plan to bring them to scale. |
Increasing Access to HIV Testing Through Direct-to-Consumer HIV Self-Test Distribution - United States, March 31, 2020-March 30, 2021.
Hecht J , Sanchez T , Sullivan PS , DiNenno EA , Cramer N , Delaney KP . MMWR Morb Mortal Wkly Rep 2021 70 (38) 1322-1325 During 2019, approximately 34,800 new HIV infections occurred in the United States (1), and it is estimated that approximately 80% of HIV transmission occurs from persons who either do not know they have HIV infection or are not receiving regular care (2). Since 2006, CDC has recommended that persons who are disproportionately affected by HIV (including men who have sex with men [MSM]) should test for HIV at least annually (3,4). However, data from multiple sources indicate that these recommendations are not being fully implemented (5,6). TakeMeHome, a novel public-private partnership to deliver HIV self-testing kits to persons seeking HIV testing in the United States, was launched during March 2020 as home care options for testing became increasingly important during the COVID-19 pandemic. The initiation of the program coincided with the national COVID-19 Public Health Emergency declaration, issuance of stay-at-home orders, and other restrictions that led to disruption of traditional HIV testing services. During March 31, 2020-March 30, 2021, 17 state and local health departments participating in the program allowed residents of their jurisdictions to order test kits. Marketing for TakeMeHome focused on reaching gay, bisexual, and MSM through messages and embedded links in gay dating applications. Most participants in the program reported that they had either never tested for HIV (36%) or that they had last tested >1 year before receiving their self-test kit (56%). After receiving the self-test kit, >10% of respondents reported accessing additional prevention services. Health departments can increase options for HIV testing by distributing publicly funded self-test kits to persons without proximate access to clinic-based testing or who prefer to test at home. Increased and regular HIV testing among MSM will help meet annual testing goals. |
Time From HIV Infection to Diagnosis in the U.S., 2014-2018
Peruski AH , Wu B , Linley L , Delaney KP , DiNenno EA , Johnson AS . Am J Prev Med 2021 61 (5) 636-643 INTRODUCTION: Understanding the role of sociologic, structural, and biomedical factors that influence the length of time from HIV infection to diagnosis and reducing the time from infection to diagnosis are critical for achieving the goals of the Ending the HIV Epidemic initiative. In a retrospective analysis, the length of time from HIV infection to diagnosis and its association with individual- and facility-level attributes are determined. METHODS: Data reported by December 2019 to the U.S. National HIV Surveillance System for people with HIV diagnosed during 2014-2018 were analyzed during December 2020. A CD4 depletion model was used to estimate the time from HIV infection to diagnosis. RESULTS: During 2018, the median time from HIV infection to diagnosis was shortest for those infections diagnosed using the rapid testing algorithm (30.3 days, 95% CI=25.5, 34.5) than those diagnosed using the recommended (41.0 days, 95% CI=39.5, 42.0), traditional (37.0 days, 95% CI=29.5, 43.5), or other (35.5 days, 95% CI=32.5, 38.0) diagnostic testing algorithms. From 2014 to 2018, the time from HIV infection to diagnosis remained stable overall for all testing methods except for the traditional diagnostic testing algorithm. In multivariate analyses, those more likely to have HIV diagnosed closer to the time of infection were younger, were White, had transmission risk factors of injection drug use or heterosexual contact (for female individuals) or male-to-male sexual contact and injection drug use, or had HIV diagnosed at a correctional or screening facility (p<0.01). CONCLUSIONS: Providing access to expanded testing, including rapid testing in nonclinical settings, is likely to result in a decrease in the length of time a person is unaware of their HIV infection and thus reduce onward transmission of HIV infection. |
Estimating Gains in HIV Testing by Expanding HIV Screening at Routine Checkups
Patel D , Williams WO , Heitgerd J , Taylor-Aidoo N , DiNenno EA . Am J Public Health 2021 111 (8) e1-e4 Objectives. To estimate gains in the prevalence of individuals who had ever been tested for HIV overall and by subpopulations from increases in the percentage of persons who had a routine checkup and were tested. Methods. We used data from the 2019 Behavioral Risk Factor Surveillance System to determine the prevalence of individuals who were ever tested for HIV and the prevalence of missed opportunities for HIV testing among those never tested in the United States. We assessed the effect of absolute percentage increases in having ever been tested among those who had a past-year routine checkup on increasing the overall prevalence of having ever been tested. Results. In 2019, 49.5% of US adults had ever been tested for HIV; 34.5% had a missed opportunity. A 50% increase in testing at routine checkups would increase the prevalence of having ever been tested to 84.0%. Increases in the prevalence of having ever been tested ($85%) was highest among persons aged 35 to 54 years, Black persons, persons who were female at birth, persons with health insurance, and persons reporting HIV risk behaviors. Conclusions. Fully incorporating HIV screening into primary care would greatly increase the proportion of US adults who have been tested for HIV. Public Health Implications.Continued efforts to promote HIV testing, including implementing routine screening in clinical settings, will help ensure that all US adults know their HIV status.

HIV testing trends at visits to physician offices, community health centers, and emergency departments - United States, 2009-2017
Hoover KW , Huang YA , Tanner ML , Zhu W , Gathua NW , Pitasi MA , DiNenno EA , Nair S , Delaney KP . MMWR Morb Mortal Wkly Rep 2020 69 (25) 776-780 In 2019, the U.S. Department of Health and Human Services launched the Ending the HIV Epidemic: A Plan for America (EHE) initiative to end the U.S. human immunodeficiency virus (HIV) epidemic by 2030. A critical component of the EHE initiative involves early diagnosis of HIV infection, along with prevention of new transmissions, treatment of infections, and response to HIV outbreaks (1). HIV testing is the first step in identifying persons with HIV infection who need to be engaged in treatment and care as well as persons with a negative HIV test result and who are at high risk for infection and can benefit from HIV preexposure prophylaxis (PrEP) and other prevention services. These opportunities are often missed for persons receiving clinical services in ambulatory care settings (2). Data from the 2009-2016 National Ambulatory Medical Care Survey (NAMCS) and 2009-2017 National Hospital Ambulatory Medical Care Survey (NHAMCS) were analyzed to estimate trends in HIV testing at visits by males and nonpregnant females to physician offices, community health centers (CHCs), and emergency departments (EDs) in the United States. HIV tests were performed at 0.63% of 516 million visits to physician offices, 2.65% of 37 million visits to CHCs, and 0.55% of 87 million visits to EDs. The percentage of visits with an HIV test did not increase at visits to physician offices during 2009-2016, increased at visits to CHC physicians during 2009-2014, and increased slightly at visits to EDs during 2009-2017. All adolescents and adults should have at least one HIV test in their lifetime (3). Strategies that reduce clinical barriers to HIV testing (e.g., clinical decision supports that use information in electronic health records [EHRs] to order an HIV test for persons who require one or standing orders for routine opt-out testing) are needed to increase HIV testing at ambulatory care visits. |
Self-reported prevalence of HIV testing among those reporting having been diagnosed with selected sexually transmitted infections or hepatitis C, United States, 2005-2016
Patel SN , Delaney KP , Pitasi MA , Oraka E , Tao G , Van Handel M , Kilmer G , DiNenno EA . Sex Transm Dis 2020 47 S53-S60 BACKGROUND: Persons with sexually transmitted infections (STIs) or hepatitis C virus (HCV) infection often have indicators of HIV risk. We used weighted data from six cycles of the National Health and Nutrition Examination Survey (NHANES) to assess the proportion of persons who reported ever being diagnosed with a selected STI or HCV infection and who reported that they were ever tested for HIV. METHODS: Persons aged 20-59 years with prior knowledge of HCV infection before receiving NHANES HCV RNA positive results (2005-2012) or reporting ever being told by a doctor that they had HCV infection (2013-2016), or ever had genital herpes, or had chlamydia or gonorrhea in the past 12 months, were categorized as having had a selected STI or HCV infection. Weighted proportions and 95% confidence intervals were estimated for reporting ever being tested for HIV for those who did and did not report a selected STI or HCV infection. RESULTS: A total of 19,102 respondents had non-missing data for STI and HCV diagnoses and HIV testing history; 44.4% reported ever having been tested for HIV and 5.2% reported being diagnosed with a selected STI or HCV infection. The proportion reporting an HIV test was higher for the group that reported a STI or HCV infection than the group that did not. CONCLUSION: Self-reported HIV testing remains low in the United States, even among those who reported a previous selected STI or HCV infection. Ensuring HIV tests are conducted routinely for those with overlapping risk factors can help facilitate diagnosis of HIV infections. |
HIV testing and linkage to care among transgender women who have sex with men: 23 U.S. cities
Pitasi MA , Clark HA , Chavez PR , DiNenno EA , Delaney KP . AIDS Behav 2020 24 (8) 2442-2450 Transgender women face unique barriers to HIV testing and linkage to care. This article describes the results of a national testing initiative conducted by 36 community-based and other organizations using a variety of recruitment and linkage-to-care strategies. A total of 2191 HIV tests were conducted with an estimated 1877 unique transgender women, and 4.6% of the transgender women had confirmed positive results. Two thirds (66.3%) were linked to care within approximately three months of follow-up, and the median time to linkage was 7 days. Transgender women tested at clinical sites were linked to care faster than those tested at non-clinical sites (median: 0 vs. 12 days; P = .003). Despite the use of a variety of linkage-to-care strategies, the proportion of transgender women successfully linked to care was below national goals. Tailored programs and interventions are needed to increase HIV testing and improve timely linkage to care in this population. |
Trends in HIV testing among US adults, aged 18-64 years, 2011-2017
Patel D , Johnson CH , Krueger A , Maciak B , Belcher L , Harris N , DiNenno EA . AIDS Behav 2019 24 (2) 532-539 In 2006, Centers for Disease Control and Prevention (CDC) recommended HIV screening in healthcare or clinical settings for all persons aged 13-64 years and annual rescreening for populations at high risk for HIV. We used the Behavioral Risk Factor Surveillance System to describe the prevalence and trends of ever tested for HIV and tested for HIV in the past 12 months among US adults. The percentage of ever tested increased from 42.9% in 2011 to 45.9% in 2017; testing in the past 12 months increased from 13.2% in 2011 to 14.8% in 2017. Despite these increases, less than half of US adults have ever been tested for HIV over ten years after CDC's recommendations. Increasing the prevalence of routine HIV screening and rescreening among individuals at high risk will reduce the number of undiagnosed persons with HIV infection and thus prevent new HIV infections-a key strategy in the Ending the HIV Epidemic initiative. |
HIV data to care-using public health data to improve HIV care and prevention
Sweeney P , DiNenno EA , Flores SA , Dooley S , Shouse RL , Muckleroy S , Margolis AD . J Acquir Immune Defic Syndr 2019 82 Suppl 1 S1-s5 BACKGROUND: "Data to Care" (D2C) is a public health strategy that uses surveillance and other data to improve continuity of HIV care for persons with HIV (PWH) by identifying those who are in need of medical care or other services and facilitating linkage to these services. The primary goal of D2C is to increase the number of PWH who are engaged in care and virally suppressed. METHODS: Data to Care can be implemented using several approaches. Surveillance-based D2C is usually initiated by health departments, using HIV surveillance and other data to identify those not in care. Health care providers may also initiate D2C by identifying patients who may have fallen out of care and working collaboratively with health departments to investigate, locate, and relink the patients to medical care or other needed services. RESULTS: Although D2C is a relatively new strategy, health department D2C programs have reported both promising results (eg, improved surveillance data quality and successful linkage to or re-engagement in care for PWH) and challenges (eg, incomplete or inaccurate data in surveillance systems, barriers to data sharing, and limitations of existing data systems). CONCLUSIONS: Data to Care is expected to enable health departments to move closer toward achieving national HIV prevention goals. However, additional information on appropriate implementation practices at each step of the D2C process is needed. This JAIDS Special Supplement explores how CDC funding to state health departments (eg, technical assistance and demonstration projects), and partnerships across federal agencies, are advancing our knowledge of D2C. |
HIV testing in 50 local jurisdictions accounting for the majority of new HIV diagnoses and seven states with disproportionate occurrence of HIV in rural areas, 2016-2017
Pitasi MA , Delaney KP , Brooks JT , DiNenno EA , Johnson SD , Prejean J . MMWR Morb Mortal Wkly Rep 2019 68 (25) 561-567 Since 2006, CDC has recommended universal screening for human immunodeficiency virus (HIV) infection at least once in health care settings and at least annual rescreening of persons at increased risk for infection (1,2), but data from national surveys and HIV surveillance demonstrate that these recommendations have not been fully implemented (3,4). The national Ending the HIV Epidemic initiative* is intended to reduce the number of new infections by 90% from 2020 to 2030. The initiative focuses first on 50 local jurisdictions (48 counties, the District of Columbia, and San Juan, Puerto Rico) where the majority of new diagnoses of HIV infection in 2016 and 2017 were concentrated and seven states with a disproportionate occurrence of HIV in rural areas relative to other states (i.e., states with at least 75 reported HIV diagnoses in rural areas that accounted for >/=10% of all diagnoses in the state).(dagger) This initial geographic focus will be followed by wider implementation of the initiative within the United States. An important goal of the initiative is the timely identification of all persons with HIV infection as soon as possible after infection (5). CDC analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS)( section sign) to assess the percentage of adults tested for HIV in the United States nationwide (38.9%), in the 50 local jurisdictions (46.9%), and in the seven states (35.5%). Testing percentages varied widely by jurisdiction but were suboptimal and generally low in jurisdictions with low rates of diagnosis of HIV infection. To achieve national goals and end the HIV epidemic in the United States, strategies must be tailored to meet local needs. Novel screening approaches might be needed to reach segments of the population that have never been tested for HIV. |
Men who have sex with men (MSM) who have not previously tested for HIV: Results from the MSM Testing Initiative, United States (2012-2015)
Clark HA , Oraka E , DiNenno EA , Wesolowski LG , Chavez PR , Pitasi MA , Delaney KP . AIDS Behav 2018 23 (2) 359-365 The Centers for Disease Control and Prevention recommends annual HIV tests for men who have sex with men (MSM), yet some have never tested. We analyzed data from the MSM Testing Initiative. Of 68,185 HIV tests, 8% were with MSM who never previously tested ("first-time testers"). Among tests with first-time testers, 70.7% were with MSM from racial or ethnic minorities; 66.5% were with MSM younger than 30 years. Tests with MSM who reported female partners only during the past year (compared to male partners only) or were recruited for at-home testing (compared to venue-based recruitment) were 4 times (prevalence ratio [PR] 3.62, 95% CI 3.15-4.15) and 5 times as likely (PR 4.69, 95% CI 4.22-5.21) to be associated with first-time testing. At-home testing and focusing on MSM who have sex with women may be effective methods for reaching MSM who are first-time testers. |
Interval since last HIV test for men and women with recent risk for HIV infection - United States, 2006-2016
Pitasi MA , Delaney KP , Oraka E , Bradley H , DiNenno EA , Brooks JT , Prejean J . MMWR Morb Mortal Wkly Rep 2018 67 (24) 677-681 Since 2006, CDC has recommended routine screening of all persons aged 13-64 years for human immunodeficiency virus (HIV) and at least annual rescreening of persons at higher risk (1). However, national surveillance data indicate that many persons at higher risk for HIV infection are not screened annually, and delays in diagnosis persist (2). CDC analyzed 2006-2016 data from the General Social Survey (GSS)* and estimated that only 39.6% of noninstitutionalized U.S. adults had ever tested for HIV. Among persons ever tested, the estimated median interval since last test was 1,080 days or almost 3 years. Only 62.2% of persons who reported HIV-related risk behaviors in the past 12 months were ever tested for HIV, and the median interval since last test in this group was 512 days (1.4 years). The percentage of persons ever tested and the interval since last test remained largely unchanged during 2006-2016. More frequent screening of persons with ongoing HIV risk is needed to achieve full implementation of CDC's screening recommendations and to prevent new infections. Integration of routine screening as standard clinical practice through existing strategies, such as electronic medical record prompts (3), or through new, innovative strategies might be needed to increase repeat screening of persons with ongoing risk. |
Stigmatizing attitudes toward people living with HIV among adults and adolescents in the United States
Pitasi MA , Chavez PR , DiNenno EA , Jeffries WLIv , Johnson CH , Demeke H , August EM , Bradley H . AIDS Behav 2018 22 (12) 1-5 Stigmatizing attitudes toward people living with HIV (PLWH) cause psychological distress for PLWH and hinder HIV prevention efforts. We estimated the prevalence of stigmatizing attitudes among 6809 adults and 885 adolescents who responded to online surveys in 2015. Fear of casual contact with PLWH was reported by 17.5% [95% confidence interval (CI) 16.3–18.6%] of adults and 31.6% (CI 27.8–35.4%) of adolescents. Among adults, 12.5% (CI 11.6–13.5%) endorsed a measure of moral judgment toward PLWH. Stigmatizing attitudes toward PLWH persist in the United States. Continued monitoring of these attitudes and efforts to reduce associated stigma are warranted. © 2018 This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply |

Neilan AM , Dunville R , Ocfemia MCB , Salomon JA , Francke JA , Bulteel AJB , Wang LY , Hsu KK , DiNenno EA , Walensky RP , Parker RA , Freedberg KA , Ciaranello AL . J Adolesc Health 2018 62 (1) 22-28 PURPOSE: To assess the optimal age at which a one-time HIV screen should begin for adolescents and young adults (AYA) in the U.S. without identified HIV risk factors, incorporating clinical impact, costs, and cost-effectiveness. METHODS: We simulated HIV-uninfected 12-year-olds in the U.S. without identified risk factors who faced age-specific risks of HIV infection (.6-71.3/100,000PY). We modeled a one-time screen ($36) at age 15, 18, 21, 25, or 30, each in addition to current U.S. screening practices (30% screened by age 24). Outcomes included retention in care, virologic suppression, life expectancy, lifetime costs, and incremental cost-effectiveness ratios in $/year-of-life saved (YLS) from the health-care system perspective. In sensitivity analyses, we varied HIV incidence, screening and linkage rates, and costs. RESULTS: All one-time screens detected a small proportion of lifetime infections (.1%-10.3%). Compared with current U.S. screening practices, a screen at age 25 led to the most favorable care continuum outcomes at age 25: proportion diagnosed (77% vs. 51%), linked to care (71% vs. 51%), retained in care (68% vs. 44%), and virologically suppressed (49% vs. 32%). Compared with the next most effective screen, a screen at age 25 provided the greatest clinical benefit, and was cost-effective ($96,000/YLS) by U.S. standards (<$100,000/YLS). CONCLUSIONS: For U.S. AYA without identified risk factors, a one-time routine HIV screen at age 25, after the peak of incidence, would optimize clinical outcomes and be cost-effective compared with current U.S. screening practices. Focusing screening on AYA ages 18 or younger is a less efficient use of a one-time screen among AYA than screening at a later age. |
Evaluating the evidence for more frequent than annual HIV screening of gay, bisexual, and other men who have sex with men in the United States: Results from a systematic review and CDC Expert Consultation
DiNenno EA , Prejean J , Delaney KP , Bowles K , Martin T , Tailor A , Dumitru G , Mullins MM , Hutchinson A , Lansky A . Public Health Rep 2017 133 (1) 33354917738769 The Centers for Disease Control and Prevention (CDC) recommended in 2006 that sexually active gay, bisexual, and other men who have sex with men (MSM) be screened for human immunodeficiency virus (HIV) at least annually. A workgroup comprising CDC and external experts conducted a systematic review of the literature, including benefits, harms, acceptability, and feasibility of annual versus more frequent screening among MSM, to determine whether evidence was sufficient to change the current recommendation. Four consultations with managers of public and nonprofit HIV testing programs, clinics, and mathematical modeling experts were conducted to provide input on the programmatic and scientific evidence. Mathematical models predicted that more frequent than annual screening of MSM could prevent some new HIV infections and would be more cost-effective than annual screening, but this evidence was considered insufficient due to study design. Evidence supports CDC's current recommendation that sexually active MSM be screened at least annually. However, some MSM might benefit from more frequent screening. Future research should evaluate which MSM subpopulations would benefit most from more frequent HIV screening. |
HIV testing among transgender women and men - 27 states and Guam, 2014-2015
Pitasi MA , Oraka E , Clark H , Town M , DiNenno EA . MMWR Morb Mortal Wkly Rep 2017 66 (33) 883-887 Transgender persons are at high risk for human immunodeficiency virus (HIV) infection; in a recent analysis of the results of over nine million CDC funded HIV tests, transgender women* had the highest percentage of confirmed positive results (2.7%) of any gender category. Transgender men, particularly those who have sex with cisgender section sign men, are also at high risk for infection. HIV testing is critical for detecting and treating persons who are infected and delivering preventive services to those who are uninfected. CDC recommends that persons at high risk for HIV infection be screened for HIV at least annually, although transgender persons are not specified in the current recommendations. CDC analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS) to describe HIV testing among transgender women and men and two cisgender comparison groups in 27 states and Guam. After adjusting for demographic characteristics, transgender women and men had a lower prevalence of ever testing and past year testing for HIV (35.6% and 31.6% ever, and 10.0% and 10.2% past year, respectively) compared with cisgender gay and bisexual men (61.8% ever and 21.6% past year) and instead reported testing at levels comparable to cisgender heterosexual men and women (35.2% ever, and 8.6% past year). This finding suggests that transgender women and men might not be sufficiently reached by current HIV testing measures. Tailoring HIV testing activities to overcome the unique barriers faced by transgender women and men might increase rates of testing among these populations. |
Recommendations for HIV screening of gay, bisexual, and other men who have sex with men - United States, 2017
DiNenno EA , Prejean J , Irwin K , Delaney KP , Bowles K , Martin T , Tailor A , Dumitru G , Mullins MM , Hutchinson AB , Lansky A . MMWR Morb Mortal Wkly Rep 2017 66 (31) 830-832 CDC's 2006 recommendations for human immunodeficiency virus (HIV) testing state that all persons aged 13-64 years should be screened for HIV at least once, and that persons at higher risk for HIV infection, including sexually active gay, bisexual, and other men who have sex with men (MSM), should be rescreened at least annually (1). Authors of reports published since 2006, including CDC (2), suggested that MSM, a group that is at highest risk for HIV infection, might benefit from being screened more frequently than once each year. In 2013, the U.S. Preventive Services Task Force (USPSTF) found insufficient evidence to specify an HIV rescreening interval but recommended annual screening for MSM as a reasonable approach (3). However, some HIV providers have begun to offer more frequent screening, such as once every 3 or 6 months, to some MSM. A CDC work group conducted a systematic literature review and held four expert consultations to review programmatic experience to determine whether there was sufficient evidence to change the 2006 CDC recommendation (i.e., at least annual HIV screening of MSM in clinical settings). The CDC work group concluded that the evidence remains insufficient to recommend screening more frequently than at least once each year. CDC continues to recommend that clinicians screen asymptomatic sexually active MSM at least annually. Each clinician can consider the benefits of offering more frequent screening (e.g., once every 3 or 6 months) to individual MSM at increased risk for acquiring HIV infection, weighing their patients' individual risk factors, local HIV epidemiology, and local testing policies. |
HIV testing among internet-using MSM in the United States: Systematic review
Noble M , Jones AM , Bowles K , DiNenno EA , Tregear SJ . AIDS Behav 2016 21 (2) 561-575 Regular HIV testing enables early identification and treatment of HIV among at-risk men who have sex with men (MSM). Characterizing HIV testing needs for Internet-using MSM informs development of Internet-facilitated testing interventions. In this systematic review we analyze HIV testing patterns among Internet-using MSM in the United States who report, through participation in an online study or survey, their HIV status as negative or unknown and identify demographic or behavioral risk factors associated with testing. We systematically searched multiple electronic databases for relevant English-language articles published between January 1, 2005 and December 16, 2014. Using meta-analysis, we summarized the proportion of Internet-using MSM who had ever tested for HIV and the proportion who tested in the 12 months preceding participation in the online study or survey. We also identified factors predictive of these outcomes using meta-regression and narrative synthesis. Thirty-two studies that enrolled 83,186 MSM met our inclusion criteria. Among the studies reporting data for each outcome, 85 % (95 % CI 82-87 %) of participants had ever tested, and 58 % (95 % CI 53-63 %) had tested in the year preceding enrollment in the study, among those for whom those data were reported. Age over 30 years, at least a college education, use of drugs, and self-identification as being homosexual or gay were associated with ever having tested for HIV. A large majority of Internet-using MSM indicated they had been tested for HIV at some point in the past. A smaller proportion-but still a majority-reported they had been tested within the year preceding study or survey participation. MSM who self-identify as heterosexual or bisexual, are younger, or who use drugs (including non-injection drugs) may be less likely to have ever tested for HIV. The overall findings of our systematic review are encouraging; however, a subpopulation of MSM may benefit from targeted outreach. These findings indicate unmet needs for HIV testing among Internet-using MSM and identify subpopulations that might benefit from targeted outreach, such as provision of HIV self-testing kits. |
Sexually transmitted disease diagnoses among Hispanic immigrant and migrant men who have sex with men in the United States
Valverde EE , DiNenno EA , Schulden JD , Oster A , Painter T . Int J STD AIDS 2015 27 (13) 1162-1169 BACKGROUND: Hispanic immigrant/migrant men who have sex with men should be at higher risk for sexually transmitted disease/human immunodeficiency virus (STD/HIV) infections given individual-level factors associated with the migration process that have been theorised to increase susceptibility to STD/HIV infections among migrant populations, yet relatively little is known if these individual level factors are actually associated with a sexually transmitted disease infection among this population. METHODS: During 2005-2007, 2576 men and women foreign-born Hispanics were surveyed at three community-based organisations offering services to immigrant/migrant communities. We analysed demographic characteristics, sexual risk behaviours, migration patterns, and factors associated with a sexually transmitted disease diagnoses (syphilis, chlamydia, and gonorrhea) in the past 12 months among Hispanic immigrant/migrant men who have sex with men. RESULTS: Of 1482 Hispanic immigrant/migrant men surveyed who reported having sex in the past 12 months, 353 (24%) reported sex with a man, and of these, 302 answered questions regarding whether or not they had been diagnosed with a bacterial sexually transmitted disease in the past year. Of these 302 men, 25% reported being married; 42% self-identified as being heterosexual and 20% as bisexual. Twenty-nine (9.6%) men reported that they received a sexually transmitted disease diagnosis in the past year. In the multivariate logistic regression model, men who reported receiving money or goods for sex had increased odds of a self-reported sexually transmitted disease diagnosis. CONCLUSIONS: The prevalence of bacterial sexually transmitted diseases among Hispanic immigrant/migrant men who have sex with men is lower than the prevalence of bacterial sexually transmitted diseases among other men who have sex with men in the United States. Nevertheless, receiving money or goods for sex was significantly associated with a self-reported sexually transmitted disease diagnosis among Hispanic immigrant/migrant men who have sex with men. It is important to understand factors contributing to participation in exchange sex among this population. Human immunodeficiency virus/sexually transmitted disease prevention interventions tailored to non-gay identifying men who have sex with men are important for Hispanic immigrant/migrant men who have sex with men. |
Migration patterns and characteristics of sexual partners associated with unprotected sexual intercourse among Hispanic immigrant and migrant women in the United States
Valverde EE , Painter T , Heffelfinger JD , Schulden JD , Chavez P , DiNenno EA . J Immigr Minor Health 2014 17 (6) 1826-33 In 2011, Hispanic immigrant women comprised 44 % of HIV diagnoses among Hispanic women in the United States but little is known about factors that may place these women at risk for infection with HIV or sexually transmitted diseases. From March 2005 to February 2007, women were recruited at community-based organizations offering services to immigrant and migrant communities in five U.S. states. We report factors independently associated with unprotected anal and vaginal sex in the past 12 months among Hispanic immigrant and migrant women. Greater work-related mobility was associated with unprotected anal sex, while recency of immigration and prior refusal of HIV testing were associated with women's reports of unprotected vaginal sex. Prior sex with an injection drug user was associated with reports of both unprotected anal and vaginal sex. Findings highlight the need for HIV/STD risk reduction interventions designed specifically for Hispanic immigrant and migrant women. |
Piloting a system for behavioral surveillance among heterosexuals at increased risk of HIV in the United States
DiNenno EA , Oster AM , Sionean C , Denning P , Lansky A . Open AIDS J 2012 6 169-76 OBJECTIVES: During the past decade, the number and proportion of reported HIV cases in the United States acquired through heterosexual contact has increased markedly. CDC employs the National HIV Behavioral Surveillance System (NHBS) to monitor risk behaviors and HIV prevalence in high-risk populations. To identify a target population for conducting NHBS among heterosexuals at increased risk for HIV (NHBS-HET), CDC designed, implemented and evaluated a pilot study. METHODS: The pilot study was conducted in 25 US metropolitan statistical areas in 2006-7. We recruited men and women who reported sex with at least one opposite-sex partner during the past year for a behavioral survey and HIV test. We investigated the relationship between newly diagnosed HIV infection and individual risk behaviors, sexual network characteristics, and social-structural characteristics to arrive at a definition of a heterosexual at increased risk of HIV. RESULTS: Of 14,750 participants in the analysis, 207 (1.4%) had newly diagnosed HIV infection. Using low socioeconomic status (SES) as a criterion for defining a heterosexual at increased risk for HIV resulted in optimal rates of HIV prevalence, specificity, sensitivity and practicality. CONCLUSIONS: Results from the NHBS pilot study underscore the key role of social factors as determinants of HIV infection risk among U.S. heterosexuals, and low SES was incorporated into the definition of a heterosexual at increased risk for HIV in NHBS-HET cycles. Future cycles of NHBS-HET will help tailor prevention programs for those populations most at risk of HIV in the US. |
A mathematical model of comprehensive test-and-treat services and HIV incidence among men who have sex with men in the United States
Sorensen SW , Sansom SL , Brooks JT , Marks G , Begier EM , Buchacz K , Dinenno EA , Mermin JH , Kilmarx PH . PLoS One 2012 7 (2) e29098 BACKGROUND: Early diagnosis and treatment of HIV infection and suppression of viral load are potentially powerful interventions for reducing HIV incidence. A test-and-treat strategy may have long-term effects on the epidemic among urban men who have sex with men (MSM) in the United States and may achieve the 5-year goals of the 2010 National AIDS Strategy that include: 1) lowering to 25% the annual number of new infections, 2) reducing by 30% the HIV transmission rate, 3) increasing to 90% the proportion of persons living with HIV infection who know their HIV status, 4) increasing to 85% the proportion of newly diagnosed patients linked to clinical care, and 5) increasing by 20% the proportion of HIV-infected MSM with an undetectable HIV RNA viral load. METHODS AND FINDINGS: We constructed a dynamic compartmental model among MSM in an urban population (based on New York City) that projects new HIV infections over time. We compared the cumulative number of HIV infections in 20 years, assuming current annual testing rate and treatment practices, with new infections after improvements in the annual HIV testing rate, notification of test results, linkage to care, initiation of antiretroviral therapy (ART) and viral load suppression. We also assessed whether five of the national HIV prevention goals could be met by the year 2015. Over a 20-year period, improvements in test-and-treat practice decreased the cumulative number of new infections by a predicted 39.3% to 69.1% in the urban population based on New York City. Institution of intermediate improvements in services would be predicted to meet at least four of the five goals of the National HIV/AIDS Strategy by the 2015 target. CONCLUSIONS: Improving the five components of a test-and-treat strategy could substantially reduce HIV incidence among urban MSM, and meet most of the five goals of the National HIV/AIDS Strategy. |
Performance of premarket rapid hepatitis C virus antibody assays in 4 National Human Immunodeficiency Virus Behavioral Surveillance System sites
Smith BD , Teshale E , Jewett A , Weinbaum CM , Neaigus A , Hagan H , Jenness SM , Melville SK , Burt R , Thiede H , Al-Tayyib A , Pannala PR , Miles IW , Oster AM , Smith A , Finlayson T , Bowles KE , Dinenno EA . Clin Infect Dis 2011 53 (8) 780-6 SUMMARY: Performance characteristics of rapid assays for hepatitis C virus antibody were evaluated in 4 National HIV Behavioral Surveillance System injection drug use sites. The highest assay-specific sensitivities achieved for the Chembio, MedMira and OraSure tests were 94.0%, 78.9%, and 97.4%, respectively; the highest specificities were 97.7%, 83.3%, and 100%, respectively. BACKGROUND: The Centers for Disease Control and Prevention (CDC) estimates that 4.1 million Americans have been infected with hepatitis C virus (HCV) and 75%-80% of them are living with chronic HCV infection, many unaware of their infection. Persons who inject drugs (PWID) account for 57.5% of all persons with HCV antibody (anti-HCV) in the United States. Currently no point-of-care tests for HCV infection are approved for use in the United States. METHODS: Surveys and testing for human immunodeficiency virus (HIV) and anti-HCV were conducted among persons who reported injection drug use in the past 12 months as part of the National HIV Behavioral Surveillance System in 2009. The sensitivity and specificity of point-of-care tests (finger-stick and 2 oral fluid rapid assays) from 3 manufacturers (Chembio, MedMira, and OraSure) were evaluated in field settings in 4 US cities. Results. Sensitivity (78.9%-97.4%) and specificity (80.0%-100.0%) were variable across assays and sites. The highest assay-specific sensitivities achieved for the Chembio, MedMira, and OraSure tests were 94.0%, 78.9% and 97.4%, respectively; the highest specificities were 97.7%, 83.3%, and 100%, respectively. In multivariate analysis, false-negative anti-HCV results were associated with HIV positivity for the Chembio oral assay (adjusted odds ratio, 8.4-9.1; P < .01) in 1 site (New York City). CONCLUSIONS: Sensitive rapid anti-HCV assays are appropriate and feasible for high-prevalence, high-risk populations such as PWID, who can be reached through social service settings such as syringe exchange programs and methadone maintenance treatment programs. |
