Mpox and Vaccine Knowledge, Beliefs, and Sources of Trusted Information Among Gay, Bisexual, and Other Men Who Have Sex With Men in the U.S.

Introduction: This research aims to characterize disparities in mpox- and vaccine-related knowledge in gay, bisexual, and other men who have sex with men in the U.S. Methods: The authors conducted a study using the American Men's Internet Survey, which includes 823 cisgender (defined as their gender identity matching their sex assigned at birth) males aged ≥15 years from August 5 to 15, 2022. The authors evaluated sociodemographic and behavioral factors associated with mpox knowledge, including race/ethnicity, region, age group, and HIV pre-exposure prophylaxis use using chi-square tests. Results: The authors identified knowledge gaps, with many participants unsure about whether individuals need 2 doses of the vaccine (34.4%) and whether the vaccine confers immediate protection (27.2%). The authors observed racial and regional disparities (p<0.01), with 24.4% of non-Hispanic Black men and 18.1% of men living in the South reporting little to no mpox awareness. Among the 707 self-reported HIV-negative participants, people who used pre-exposure prophylaxis within the past year were more likely to exhibit high awareness about mpox than people who did not use pre-exposure prophylaxis. Conclusions: Findings suggest the potential to leverage existing networks (i.e., sexually transmitted infection or general health care services with pre-exposure prophylaxis use) for future targeted health service programming or education campaigns for mpox vaccination among gay, bisexual, and other men who have sex with men.

HIV: California's 2018 criminalization reform and testing among those reporting risk behavior.

HIV criminalization laws may discourage HIV testing. We tested whether California's 2018 HIV criminalization law reform increased the likelihood of past-year HIV testing compared to Nevada, which did not reform its HIV criminalization law. We fitted two difference-in-differences logistic regression models: one for all respondents reporting behaviors that increase the chances of getting or transmitting HIV, and one for male respondents reporting these behaviors. All analyses accounted for the complex survey design of BRFSS. HIV criminalization reform was significantly associated with an increased likelihood of past-year HIV testing. After reform, the predicted marginal probability of past-year HIV testing increased by six percentage points. By comparison, probabilities of a past-year HIV test decreased in Nevada. HIV criminalization law reform may increase the likelihood of getting tested by individuals who engage in behaviors that increase the chances of getting or transmitting HIV.

Testing trends and co-testing patterns for HIV, hepatitis C and sexually transmitted infections (STIs) in Emergency departments.

Background: Many underserved populations use Emergency Department (EDs) as primary sources of care, representing an important opportunity to provide infectious disease testing and linkage to care. We explored national ED testing trends and co-testing patterns for HIV, hepatitis C, and sexually transmitted infections (STIs). Methods: We used 2010-2019 Healthcare Cost and Utilization Project, Nationwide Emergency Department Sample data to estimate ED visit testing rates for HIV, hepatitis C, chlamydia, gonorrhea, and syphilis infections, identified by Current Procedural Terminology codes. Trends and co-testing (visit with tests for > 1 infection) patterns were analyzed by sociodemographic, hospital, and visit characteristics. Trends were evaluated as the average annual percentage change (AAPC) using the Joinpoint Regression. Results: During 2010-2019, testing events per 1000 visits (AAPCs) increased for HIV from 1.3 to 4.2 (16.3 %), hepatitis C from 0.4 to 2.2 (25.1 %), chlamydia from 9.1 to 16.0 (6.6 %), gonorrhea from 8.4 to 15.7 (7.4 %), and syphilis from 0.7 to 2.0 (12.9 %). Rate increases varied by several characteristics across infections. The largest AAPC increases were among visits by groups with lower base rate testing in 2010, including persons aged ≥ 65 years (HIV: 36.4 %), with Medicaid (HIV: 43.8 %), in the lowest income quintile (hepatitis C: 36.9 %), living in the West (syphilis: 49.4 %) and with non-emergency diagnoses (hepatitis C: 44.1 %). Co-testing increased significantly for all infections except hepatitis C. Conclusions: HIV, hepatitis C, and STI testing increased in EDs during 2010-2019; however, co-testing patterns were inconsistent. Co-testing may improve diagnosis and linkage to care, especially in areas experiencing higher rates of infection.

Disease Intervention Specialist-Delivered Interventions and Other Partner Services for HIV and Sexually Transmitted Infections: A Systematic Review.

INTRODUCTION: Disease intervention specialists (DIS) are critical for delivering partner services programs that provide partner notification, counseling, referral, and other services for HIV, sexually transmitted infections (STIs), and other infections. This systematic review of partner services and other DIS-delivered interventions for HIV and STIs was conducted to summarize the effectiveness of these programs and identify evidence gaps. METHODS: A systematic literature review was conducted with a narrative synthesis. Articles were located using keyword searches in MEDLINE, Web of Science, CINAHL, and ProQuest through December 2022 and analyzed in 2023-2024. Included studies addressed an intervention of partner services or other DIS-delivered services for HIV or STIs; a United States setting; primary data collection; and an external comparison group or pre-post design. RESULTS: A total of 1,915 unique records were screened for eligibility, with 30 studies included. Overall, DIS-delivered interventions improved clinical outcomes among index patients and population outcomes. Many studies focused on program process measures rather than population-level epidemiologic outcomes. All but one studies were scored as having low or medium strength of evidence. CONCLUSIONS: The evidence could be strengthened by establishing a streamlined set of core metrics, assessing impact using rigorous causal inference methodologies, linking program and clinical data systems, and supplementing impact evaluations with evidence on implementation strategies.

Findings from the First Year of a Federally Funded, Direct-to-Consumer HIV Self-Test Distribution Program - United States, March 2023-March 2024.

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.

Behavior Change Among HIV-Negative Men Who Have Sex with Men Not Using PrEP in the United States.

This study measures changes in condomless anal sex (CAS) among HIV-negative men who have sex with men (MSM) who are not taking pre-exposure prophylaxis (PrEP). It considers the 2014-2019 cycles of the American Men's Internet Survey, a serial, cross-sectional web-based survey of US cisgender MSM aged ≥ 15 years, in which ~ 10% of each year's sample is drawn from the previous year. Among those surveyed for 2 years who remained HIV-negative and off PrEP, reports of having any CAS and of CAS partner number were compared across years. We disaggregated by partner HIV status, and considered demographic predictors. The overall population saw a significant 2.2 percentage-point (pp) increase in reports of any CAS year-over-year. Sub-populations with the largest year-on-year increases were 15-24-year-olds (5.0-pp) and Hispanic respondents (5.1-pp), with interaction (young Hispanic respondents = 12.8-pp). On the relative scale, these numbers correspond to 3.2%, 7.2%, 7.3% and 18.7%, respectively. Absolute increases were concentrated among partners reported as HIV-negative. Multivariable analyses for CAS initiation found effects concentrated among Hispanic and White youth and residents of fringe counties of large metropolitan areas. CAS partner number increases were similarly predicted by Hispanic identity and young age. Although condom use remains more common than PrEP use, increasing CAS among MSM not on PrEP suggests potential new HIV transmission pathways. Concentration of increases among 18-24-year-old MSM portends future increases in the proportion of newly diagnosed HIV that occur among youth. Concentration among young Hispanic MSM will likely expand existing disparities. Although reducing barriers to PrEP remains vital, condom promotion for MSM remains a key public health practice and appears to be missing key audiences. LGBTQ+-inclusive sex education is one avenue for enhancing these efforts.

Modelling the impact of vaccination and sexual behaviour adaptations on mpox cases in the USA during the 2022 outbreak.

BACKGROUND: The 2022 mpox outbreak has infected over 30 000 people in the USA, with cases declining since mid-August. Infections were commonly associated with sexual contact between men. Interventions to mitigate the outbreak included vaccination and a reduction in sexual partnerships. Understanding the contributions of these interventions to decreasing cases can inform future public health efforts. METHODS: We fit a dynamic network transmission model to mpox cases reported by Washington DC through 10 January 2023. This model incorporated both vaccine administration data and reported reductions in sexual partner acquisition by gay, bisexual or other men who have sex with men (MSM). The model output consisted of daily cases over time with or without vaccination and/or behavioural adaptation. RESULTS: We found that initial declines in cases were likely caused by behavioural adaptations. One year into the outbreak, vaccination and behavioural adaptation together prevented an estimated 84% (IQR 67% to 91%) of cases. Vaccination alone averted 79% (IQR 64% to 88%) of cases and behavioural adaptation alone averted 25% (IQR 10% to 42%) of cases. We further found that in the absence of vaccination, behavioural adaptation would have reduced the number of cases, but would have prolonged the outbreak. CONCLUSIONS: We found that initial declines in cases were likely caused by behavioural adaptation, but vaccination averted more cases overall and was key to hastening outbreak conclusion. Overall, this indicates that outreach to encourage individuals to protect themselves from infection was vital in the early stages of the mpox outbreak, but that combination with a robust vaccination programme hastened outbreak conclusion.

Modifications to Sexual Behaviors Associated With Mpox (Monkeypox) Virus Transmission Among Persons Presenting for mpox Vaccination, Washington, DC, August-October, 2022.

BACKGROUND: Over 30,000 mpox cases were reported during the 2022 mpox outbreak with many cases occurring among gay, bisexual and other men who have sex with men (MSM). Decreases in U.S. mpox cases were likely accelerated by a combination of vaccination and modifications to sexual behaviors associated with mpox virus transmission. We assessed reports of sexual behavior change among participants receiving mpox vaccination in Washington, DC. METHODS: During August to October 2022, 711 adults aged ≥18 years receiving mpox vaccination at two public health clinics in Washington, DC completed a self-administered questionnaire that asked whether sexual behaviors changed since learning about mpox. We calculated the frequency and percentages of participants reporting an increase, decrease, or no change in 4 of these behaviors by demographic, clinical, and behavioral characteristics with 95% confidence intervals. RESULTS: Overall, between 46% and 61% of participants reported a decrease in sexual behaviors associated with mpox virus transmission, 39% to 54% reported no change in these behaviors, and <1% reported an increase. Approximately 61% reported decreases in one-time sexual encounters (95% confidence interval [CI], 56.8%-64.7%), 54.3% reduced numbers of sex partners (95% CI, 50.4%-58.0%), 53.4% decreased sex via a dating app or sex venue (95% CI, 49.7%-58.0%), and 45.6% reported less group sex (95% CI, 40.4%-50.9%). Reported decreases in these behaviors were higher for MSM than women; in non-Hispanic Black than non-Hispanic White participants; and in participants with human immunodeficiency virus than participants without human immunodeficiency virus. CONCLUSIONS: Most participants receiving mpox vaccination reported decreasing sexual behaviors associated with mpox virus transmission, including groups disproportionately affected by the outbreak.

Mpox Knowledge, Attitudes, and Practices Among Persons Presenting for JYNNEOS Vaccination-District of Columbia, August to October 2022.

BACKGROUND: More than 30,000 mpox cases have been confirmed in the United States since May 2022. Mpox cases have disproportionally occurred among adult gay, bisexual, and other men who have sex with men; transgender persons; and Black and Hispanic/Latino persons. We examined knowledge, attitudes, and practices regarding mpox vaccination among adults presenting for vaccination to inform prevention efforts. METHODS: We collected mixed-methods data from a convenience sample of adults presenting for JYNNEOS vaccination at 3 DC Health mpox vaccine clinics during August-October 2022. Survey and interview topics included knowledge about mpox symptoms and vaccine protection, beliefs about vaccine access, and trusted sources of information. RESULTS: In total, 352 participants completed self-administered surveys and 62 participants completed an in-depth interview. Three main themes emerged from survey and interview data. First, most participants had a general understanding about mpox, but gaps remained in comprehensive understanding about mpox symptoms, modes of transmission, vaccine protection, personal risk, and vaccine dosing strategies. Second, participants had high trust in public health agencies. Third, participants wanted more equitable and less stigmatizing access to mpox vaccine services. CONCLUSIONS: Nonstigmatizing, inclusive, and clear communication from trusted sources, including public health agencies, is needed to address mpox knowledge gaps and increase vaccine access and uptake in affected communities. Mpox outreach efforts should continue innovative approaches, including person-level risk assessment tools, to address community needs.

Potential contribution of PrEP uptake by adolescents 15-17 years old to achieving the "Ending the HIV Epidemic" incidence reduction goals in the US South.

BACKGROUND: The "Ending the HIV Epidemic" (EHE) initiative seeks to reduce new HIV infections in the U.S. by prioritizing federal resources towards highly impacted populations. Antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) are essential for reaching EHE goals. Adolescents are often at increased risk for HIV because they may lack agency in negotiating their sexual partnerships and may not have the same access to treatment and prevention as adults. This study estimates the potential contribution of expanded PrEP coverage among adolescents ages 15-17 to achieving the EHE goals in the South. METHODS: An HIV-transmission model was built to simulate the HIV epidemic in the South. Increased ART and PrEP uptake were systematically varied with and without PrEP eligibility including individuals age<18. RESULTS: Prioritizing PrEP for adolescents had a negligible impact on incidence. At 50% uptake among eligible adolescents and 90% ART coverage, including adolescents only improved the percentage of infections averted from 80.1% to 80.3%. In 10 of 15 scenarios explored, there was no reduction in new infections when PrEP eligibility was expanded to include adolescents age<18. At 95% ART coverage at the population-level incidence among adolescents declined by over 80%, but PrEP uptake among adolescents did not contribute to additional declines in incidence among adolescents. CONCLUSIONS: Prioritizing PrEP for adolescents did not significantly contribute to reaching EHE incidence reductions goal. Focusing resources to specific adolescent populations at risk, such sexual minority males in high incidence settings, will remain an important public health goal outside the context of EHE.

Evaluating the impact of point-of-care HIV viral load assessment on linkage to care in Baltimore, MD: a randomized controlled trial.

BACKGROUND: Integration of a sensitive point-of-care (POC) HIV viral load (VL) test into screening algorithms may help detect acute HIV infection earlier, identify people with HIV (PWH) who are not virally suppressed, and facilitate earlier referral to antiretroviral therapy (ART), or evaluation for pre-exposure prophylaxis (PrEP). This report describes a randomized clinical trial sponsored by the Centers for Disease Control and Prevention (CDC): "Ending the HIV Epidemic Through Point-of-Care Technologies" (EHPOC). The study's primary aim is to evaluate the use of a POC HIV VL test as part of a testing approach and assess the impact on time to linkage to ART or PrEP. The study will recruit people in Baltimore, Maryland, including patients attending a hospital emergency department, patients attending an infectious disease clinic, and people recruited via community outreach. The secondary aim is to evaluate the performance characteristics of two rapid HIV antibody tests approved by the United States Food and Drug Administration (FDA). METHODS: The study will recruit people 18 years or older who have risk factors for HIV acquisition and are not on PrEP, or PWH who are not taking ART. Participants will be randomly assigned to either the control arm or the intervention arm. Participants randomized to the control arm will only receive the standard-of-care (SOC) HIV screening tests. Intervention arm participants will receive a POC HIV VL test in addition to the SOC HIV diagnostic screening tests. Follow up will consist of an interim phone survey conducted at week-4 and an in-person week-12 visit. Demographic and behavioral information, and oral fluid and blood specimens will be collected at enrollment and at week-12. Survey data will be captured in a Research Electronic Data Capture (REDCap) database. Participants in both arms will be referred for either ART or PrEP based on their HIV test results. DISCUSSION: The EHPOC trial will explore a novel HIV diagnostic technology that can be performed at the POC and provide viral assessment. The study may help inform HIV testing algorithms and contribute to the evidence to support same day ART and PrEP recommendations. TRIAL REGISTRATION: NIH ClinicalTrials.gov NCT04793750. Date: 11 March 2021.

Benefits of Frequent HIV Testing in the THRIVE Demonstration Project: United States, 2015-2020.

Objectives. To describe HIV testing among clients in the Targeted Highly Effective Interventions to Reverse the HIV Epidemic (THRIVE) demonstration project and evaluate testing frequency. Methods. We identified factors associated with an average testing frequency of 180 days or less compared with more than 180 days using adjusted Poisson regression models. We performed the Kaplan-Meier survival analysis to compare time to diagnosis by testing frequency. Results. Among 5710 clients with 2 or more tests and no preexposure prophylaxis (PrEP) prescription, 42.4% were tested frequently. Black/African American clients were 21% less likely and Hispanic/Latino clients were 18% less likely to be tested frequently than were White clients. Among 71 Black/African American and Hispanic/Latino cisgender men who have sex with men and transgender women with HIV diagnoses, those with frequent testing had a median time to diagnosis of 137 days, with a diagnostic testing yield of 1.5% compared with those tested less frequently, with 559 days and 0.8% yield. Conclusions. HIV testing at least every 6 months resulted in earlier HIV diagnosis and was efficient. Persons in communities with high rates of HIV who are not on PrEP can benefit from frequent testing, and collaborative community approaches may help reduce disparities.

Achieving the "Ending the HIV Epidemic in the U.S." incidence reduction goals among at-risk populations in the South.

INTRODUCTION: Antiretroviral medication coverage remains sub-optimal in much of the United States, particularly the Sothern region, and Non-Hispanic Black or African American persons (NHB) continue to be disproportionately impacted by the HIV epidemic. The "Ending the HIV Epidemic in the U.S." (EHE) initiative seeks to reduce HIV incidence nationally by focusing resources towards the most highly impacted localities and populations. This study evaluates the impact of hypothetical improvements in ART and PrEP coverage to estimate the levels of coverage needed to achieve EHE goals in the South. METHODS: We developed a stochastic, agent-based network model of 500,000 individuals to simulate the HIV epidemic and hypothetical improvements in ART and PrEP coverage. RESULTS: New infections declined by 78.6% at 90%/40% ART/PrEP and 94.3% at 100%/50% ART/PrEP. Declines in annual incidence rates surpassed 75% by 2025 with 90%/40% ART/PrEP and 90% by 2030 with 100%/50% ART/PrEP coverage. Increased ART coverage among NHB MSM was associated with a linear decline in incidence among all MSM. Declines in incidence among Hispanic/Latino and White/Other MSM were similar regardless of which MSM race group increased their ART coverage, while the benefit to NHB MSM was greatest when their own ART coverage increased. The incidence rate among NHB women declined by over a third when either NHB heterosexual men or NHB MSM increased their ART use respectively. Increased use of PrEP was associated with a decline in incidence for the groups using PrEP. MSM experienced the largest absolute declines in incidence with increasing PrEP coverage, followed by NHB women. CONCLUSIONS: Our analysis indicates that it is possible to reach EHE goals. The largest reductions in HIV incidence can be achieved by increasing ART coverage among MSM and all race groups benefit regardless of differences in ART initiation by race. Improving ART coverage to > 90% should be prioritized with a particular emphasis on reaching NHB MSM. Such a focus will reduce the largest number of incident cases, reduce racial HIV incidence disparities among both MSM and women, and reduce racial health disparities among persons with HIV. NHB women should also be prioritized for PrEP outreach.

Impacts of COVID-19 on sexual behaviors, HIV prevention and care among men who have sex with men: A comparison of New York City and Metropolitan Atlanta.

The COVID-19 pandemic has disrupted HIV prevention, care, and transmission opportunities. This likely varies by geography, given differences in COVID-19 burden and mandates over time, and by age, given different likelihoods of severe COVID-19 consequences. We consider changes in sexual behavior, HIV testing, pre-exposure prophylaxis (PrEP) use and antiretroviral therapy (ART) use among men who have sex with men (MSM) over the first year of the COVID-19 epidemic, comparing the Atlanta metropolitan area and New York City (NYC). We use two continuous time-series datasets and one panel dataset, assessing changes over time within city and comparing across cities, and disaggregate major findings by age. For clinical results, ART use showed by far the smallest reductions, and testing the largest. Disruptions occurred concurrently between cities, despite the major wave of COVID-19, and government mandates, occurring later in Atlanta. Test positivity increased in NYC only. In both cities, younger MSM saw the greatest reductions in testing and PrEP use, but the smallest in sexual behavior. Reduced clinical service usage would be unconcerning if stemming solely from reductions in exposure; however, the patterns for young MSM suggest that the COVID-19 epidemic likely generated new conditions for increased HIV transmission, especially in this cohort.

HIV Testing Preferences and Characteristics of Those Who Have Never Tested for HIV in the United States.

BACKGROUND: The initial phase of the federal Ending the HIV Epidemic in the U.S. (EHE) initiative prioritized efforts in 57 geographic areas. The US Centers for Disease Control and Prevention recommends persons aged 13 to 64 years be tested for HIV at least once as part of routine health care; however, it is unclear how effectively these testing recommendations have been implemented in EHE priority areas. METHODS: In 2021 to 2022, we analyzed data from a Web-based, nationally representative survey of adults fielded in 2021. HIV testing preferences were compared by testing history, demographic characteristics, behaviors, and geography. RESULTS: An estimated 72.5% of US adults had never tested for HIV. Never testing was most prevalent among those aged 18 to 29 or those 50 years or older, non-Hispanic White persons, and those living in the Midwest. Among persons living in EHE priority areas and persons reporting at least one behavior that increases risk of HIV transmission, 69.1% and 48.0%, respectively, had never tested for HIV. The top 3 HIV testing preferences among never testers were as follows: testing for HIV during a routine health care visit (41.2%), testing at an urgent care or walk-in clinic (9.6%), and self-testing (8.1%). CONCLUSIONS: Most adults had not been tested for HIV, confirming that US Centers for Disease Control and Prevention recommendations are not being fully implemented, even in EHE priority areas. Moreover, most adults who never tested preferred testing in clinical settings, highlighting missed opportunities. As the EHE initiative continues to advance, it is critical to leverage preferred HIV testing modalities, such as routine testing in clinical settings or HIV self-testing.

Seroconversion, seroreversion, and serowaffling among participants initiating antiretroviral therapy in Project DETECT.

BACKGROUND: Incomplete HIV seroconversion and seroreversion are increasingly documented by testing and pre-exposure prophylaxis programs more than previously recognized. This analysis reports on incomplete seroconversion and seroreversion by specimen and test type among Project DETECT participants. METHODS: Project DETECT included a longitudinal study of point-of-care tests. Participants were categorized as having "incomplete seroconversion" if all timepoints had ≥1 nonreactive test at study censoring. Among participants with incomplete seroconversion, we defined "seroreversion" as sustained regression to nonreactive for any test following a reactive result. We define "serowaffling" as any reactive result followed by a nonreactive and then reactive result. We used Fisher's exact tests to explore relationships between Fiebig stage at ART initiation and incomplete seroconversion, seroreversion, and serowaffling. RESULTS: Twenty of 1940 Project DETECT participants met criteria for this subset. Ten participants had complete seroconversion after a median of 23 (IQR 16-47) days following initial positive tests. Ten participants had incomplete seroconversion, eight of whom had seroreversion. Incomplete seroconversion with persistent nonreactive tests was seen only with oral fluid (OF). Of eight participants with seroreversion, all experienced seroreversion of OF tests if the test was ever reactive (n = 6); seroreversion occurred in fingerstick and venipuncture tests in two participants. Serowaffling occurred in nine (45%) participants. No associations were seen between Fiebig stage at ART start and complete seroconversion, seroregression, or serowaffling in our sample. CONCLUSIONS: OF tests may be particularly susceptible to providing false-negative results. Seroreversion and incomplete seroconversion among individuals on antiretroviral treatment may represent a growing problem for HIV testing and treatment programs.

Estimated Number of Incident HIV Infections in Men Who Have Sex With Men Attributable to Gonorrhea and Chlamydia, Per Gonococcal or Chlamydial Infection, in the United States.

Using a network model, we simulated transmission of HIV, gonorrhea, and chlamydia among men who have sex with men to estimate the number of HIV infections that can be attributed to gonorrhea and chlamydia, per gonococcal and chlamydial infection. This metric can inform future modeling and health economic studies.

Distribution of HIV Self-tests by Men Who have Sex with Men (MSM) to Social Network Associates.

Internet-recruited gay, bisexual, and other men who have sex with men (MSM) were offered HIV self-tests (HIVSTs) after completing baseline, 3-, 6-, and 9-month follow-up surveys. The surveys asked about the use and distribution of these HIVSTs. Among 995 who reported on their distribution of HIVSTs, 667 (67.0%) distributed HIVSTs to their social network associates (SNAs), which resulted in 34 newly identified HIV infections among 2301 SNAs (1.5%). The main reasons participants reported not distributing HIVSTs included: wanting to use the HIVSTs themselves (74.9%); thinking that their SNAs would get angry or upset if offered HIVSTs (12.5%); or not knowing that they could give the HIVSTs away (11.3%). Self-testing programs can provide multiple HIVSTs and encourage the distribution of HIVST by MSM to their SNAs to increase awareness of HIV status among persons disproportionately affected by HIV.

RESUMEN: Hombres gais, bisexuales y otros hombres que indicaron tener contacto sexual con hombres (MSM, por sus siglas en inglés) fueron reclutados por el Internet y se les ofreció autopruebas del VIH (HIVST, por sus siglas en inglés) después de completar una encuestas inicial y encuestas de seguimiento a los 3, 6 y 9 meses. Las encuestas recogieron datos sobre el uso y distribución de estas autopruebas del VIH. De los 995 MSM que indicaron distribuir las autopruebas, 667 (67.0%) distribuyeron las autopruebas a personas en sus redes sociales (SNA, por sus siglas en inglés), resultando en 34 nuevas infecciones por el VIH identificadas entre 2,301 SNA (1.5%). Las razones principales por las que algunos participantes no distribuyeron las autopruebas del VIH incluyen: el deseo de utilizar las autopruebas del VIH para sí mismos (74.9%); pensar que las SNA se enfadarían o molestarían si se les ofreciesen autopruebas del VIH (12.5%); o no saber que podían distribuir las autopruebas del VIH (11.3%). Los programas que proporcionen múltiples autopruebas del VIH podrían alentar la distribución de las autopruebas por parte de los MSM a las SNA para aumentar el conocimento sobre el estado del VIH entre personas afectadas de manera desproporcionada por el VIH.

HIV Services and Outcomes During the COVID-19 Pandemic - United States, 2019-2021.

Increasing HIV testing, preexposure prophylaxis (PrEP), and antiretroviral therapy (ART) are pillars of the federal Ending the HIV Epidemic in the U.S. (EHE) initiative, with a goal of decreasing new HIV infections by 90% by 2030.* In response to the COVID-19 pandemic, a national emergency was declared in the United States on March 13, 2020, resulting in the closure of nonessential businesses and most nonemergency health care venues; stay-at-home orders also limited movement within communities (1). As unemployment increased during the pandemic (2), many persons lost employer-sponsored health insurance (3). HIV testing and PrEP prescriptions declined early in the COVID-19 pandemic (4-6); however, the full impact of the pandemic on use of HIV prevention and care services and HIV outcomes is not known. To assess changes in these measures during 2019-2021, quarterly data from two large U.S. commercial laboratories, the IQVIA Real World Data - Longitudinal Prescription Database (IQVIA),† and the National HIV Surveillance System (NHSS)§ were analyzed. During quarter 1 (Q1)¶ 2020, a total of 2,471,614 HIV tests were performed, 190,955 persons were prescribed PrEP, and 8,438 persons received a diagnosis of HIV infection. Decreases were observed during quarter 2 (Q2), with 1,682,578 HIV tests performed (32% decrease), 179,280 persons prescribed PrEP (6% decrease), and 6,228 persons receiving an HIV diagnosis (26% decrease). Partial rebounds were observed during quarter 3 (Q3), with 2,325,554 HIV tests performed, 184,320 persons prescribed PrEP, and 7,905 persons receiving an HIV diagnosis. The proportion of persons linked to HIV care, the number who were prescribed ART, and proportion with a suppressed viral load test (<200 copies of HIV RNA per mL) among those tested were stable during the study period. During public health emergencies, delivery of HIV services outside of traditional clinical settings or that use nonclinical delivery models are needed to facilitate access to HIV testing, ART, and PrEP, as well as to support adherence to ART and PrEP medications.
