PURPOSE To compare the role of neighborhood social disorganization factors on human immunodeficiency virus (HIV) diagnosis rates in urban and rural areas in Florida, we conducted an ecologic study of HIV diagnosis rates during 2013-2017 and social disorganization components, including concentrated disadvantage, ethnic heterogeneity, and residential instability. METHODS Indices of social disorganization components were obtained from principal component analyses of American Community Survey variables for 910 postal codes. Rural/urban classification was based on the United States Department of Agriculture Rural Urban Commuting Area codes. Using multivariable linear regression, the relationship between social disorganization indices and HIV diagnosis rates was assessed. FINDINGS The only social disorganization index that was significantly higher in rural than urban areas was concentrated disadvantage. In rural areas, the concentrated disadvantage index was significantly associated with HIV diagnosis rates (P = .007) when controlling for the other social disorganization factors but was no longer significant after additionally controlling for prevalence of people with an HIV diagnosis who were not virally suppressed. In urban areas, even after controlling for prevalence of people with HIV who were not virally suppressed, lower male-to-female population ratios and higher scores of residential instability, concentrated disadvantage, and LatinX/immigrant density indices were associated with higher HIV diagnosis rates (all P < .01). CONCLUSIONS In addition to improving community levels of viral suppression, the community contextual environment, including the rurality of the environment, needs to be considered in strategies to end the HIV epidemic in the United States.

Florida is considered an epicenter of HIV in the United States. The U.S. federal plan for Ending the HIV Epidemic (EHE) within 10 years prioritizes seven of Florida's 67 counties for intervention. We applied molecular epidemiology methods to characterize the HIV infection networks in the state and infer whether the results support the EHE. HIV sequences (N = 34,446) and associated clinical/demographic metadata of diagnosed people with HIV (PWH), during 2007 to 2017, were retrieved from the Florida Department of Health. HIV genetic networks were investigated using MicrobeTrace. Associates of clustering were identified through boosted logistic regression. Assortative trait mixing was also assessed. Bayesian phylogeographic methods were applied to evaluate evidence of imported HIV-1 lineages and illustrate spatiotemporal flows within Florida. We identified nine large clusters spanning all seven EHE counties but little evidence of external introductions, suggesting-in the absence of undersampling-an epidemic that evolved independently from the rest of the country or other external influences. Clusters were highly assortative by geography. Most of the sampled infections (82%) did not cluster with others in the state using standard molecular surveillance methods despite satisfactory sequence sampling in the state. The odds of being unclustered were higher among PWH in rural regions, and depending on demographics. A significant number of unclustered sequences were observed in counties omitted from EHE. The large number of missing sequence links may impact timely detection of emerging transmission clusters and ultimately hinder the success of EHE in Florida. Molecular epidemiology may help better understand infection dynamics at the population level and underlying disparities in disease transmission among subpopulations; however, there is also a continuous need to conduct ethical discussions to avoid possible harm of advanced methodologies to vulnerable groups, especially in the context of HIV stigmatization. IMPORTANCE The large number of missing phylogenetic linkages in rural Florida counties and among women and Black persons with HIV may impact timely detection of ongoing and emerging transmission clusters and ultimately hinder the success of epidemic elimination goals in Florida. ispartof: MICROBIOLOGY SPECTRUM vol:10 issue:6 ispartof: location:United States status: published

The research tested the psychometrics of the Centers for Disease Control and Prevention's National HIV Behavioral Surveillance (NHBS) community HIV-related stigma scale. Data was from men who have sex with men (MSM) NHBS cycles conducted 2011-2017 in Miami-Dade, Florida among n = 1455 participants. MSM were cis-gender male, 18+ years old, reported lifetime oral/anal sex with a male, and lived in Miami-Dade County. We assessed reliability using Cronbach's alpha and McDonald's omega, determined factors using principal factor analysis, and assessed construct validity using five a priori hypotheses. The scale was unidimensional, had questionable internal reliability (α = 0.68, ω = 0.69), and met four of five a priori hypotheses in the expected direction. Correlations were medium-weak in strength and only one was consistently met. Future iterations of the NHBS survey should consider replacing the 4-item community HIV-related stigma scale with an instrument that has superior internal reliability, measures multiple HIV-related stigma dimensions, and demonstrates stronger evidence of validity.La investigación evaluó la psicometrías de la escala comunitaria de estigma relacionada con el VIH de La Vigilancia del Comportamiento Nacional del VIH de los Centros de Control y la Prevención de Enfermedades (National HIV Behavioral Surveillance, NHBS por sus siglas en Ingles). Los datos fueron de hombres que tienen sexo con hombres (HSH) ciclos NHBS realizados 2011–2027 en Miami-Dade, Florida entre n = 1455 participantes. Los HSH eran hombres cisgénero, mayores de 18 años, reportando haber tenido sexo oral/anal de toda la vida con un hombre y vivían en el condado de Miami-Dale. Evaluamos la confiabilidad usando el alfa de Cronbach y el omega de McDonald, determinamos los factores usando el análisis de factores principales y evaluamos la validez de constructo usando cinco hipótesis a priori. La escala era unidimensional, tenía una fiabilidad interna cuestionable (α = 0.68, ω = 0.69), y cumplía cuatro de cinco hipótesis a priori en la dirección esperada. Las correlaciones fueron de intensidad media-débil y solo una se cumplió de manera consistente. Las iteraciones futuras de la encuesta NHBS debería considerar reemplazar la escala comunitaria de estigma relacionada con el VIH de 4 ítems por un instrumento que tenga una confiabilidad interna superior, mida múltiples dimensiones del estigma relacionado con el VIH y demuestre una evidencia mas solida de validez.

Background When considering adherence to antiretroviral therapy (ART) for HIV, many different cut-points are used. The primary goals of this study were to identify a level of self-reported medication adherence that best distinguished HIV viral suppression from non-suppression, and to compare the ability of a single-item and a 3-item adherence questionnaire to predict HIV viral suppression. Methods This cross-sectional analysis included 380 persons with HIV (PWH) from the Florida Cohort study who completed a self-reported ART adherence measure within 30-days of having an HIV viral load test. We used Receiver Operating Characteristic (ROC) curve analyses and ROCContrast to compare the ability of a single-item and a 3-item self-reported adherence measure to predict HIV viral suppression (defined as ≤ 200 copies/mL). We used the Youden index and chi square statistics to assess specific cut-points, and repeated the analysis with a different definition of HIV viral suppression (≤ 1000 copies/mL). Results The mean percent adherence was 92.4% using the single-item score and 90.4% using the 3-item score; 81.6% had viral suppression. The areas under the curve for the single-item and 3-item adherence measures were generally poor overall and not significantly different from each other (0.589 and 0.580, p = 0.67). The Youden index identified cut-points of 93% and 89% as maximizing the sensitivity and specificity for the single-item and 3-item measures, respectively, whereas a cut-point of 80% on the single-item measure was best able to discriminate those with viral suppression (58% vs. 84%, p < 0.001). Results were similar with viral suppression defined as ≤ 1000 copies/mL. Conclusions In this sample of PWH, a single question on medication adherence was as good as a 3-item questionnaire in predicting HIV viral suppression, although neither had good discriminatory ability. A cut-point close to 90% adherence maximized sensitivity and specificity, although viral suppression was very similar for nearly all measures above 80%.

People who inject drugs (PWID) are at an amplified vulnerability for experiencing a multitude of harms related to their substance use, including viral (e.g. HIV, Hepatitis C) and bacterial infections (e.g. endocarditis). Implementation of evidence-based interventions, such as syringe services programs (SSPs), remains imperative, particularly in locations at an increased risk of HIV outbreaks. This study aims to identify communities in Florida that are high-priority locations for SSP implementation by examining state-level data related to the substance use and overdose crises.State-level surveillance data were aggregated at the ZIP Code Tabulation Area (ZCTA) (The final model retained three variables of importance: (1) the number of drug-associated skin and soft tissue infection hospitalizations, (2) the number of chronic HCV infections in people aged 18-39, and 3) the number of drug-associated endocarditis hospitalizations. High-priority SSP implementation locations were identified in both urban and rural communities outside of current Ending the HIV Epidemic counties.SSPs are long researched, safe, and effective evidence-based programs that offer a variety of services that reduce disease transmission and assist with combating the overdose crisis. Opportunities to increase services in needed regions across the state now exist in Florida as supported by the expansion of the Infectious Disease Elimination Act of 2019. This study provides details where potential areas of concern may be and highlights regions where future evidence-based harm reduction programs, such as SSPs, would be useful to reduce opioid overdoses and disease transmission among PWID.Key messagesThe rate of acute HCV in Florida in 2017 was 1.9 per 100,000, nearly twice the national average.Serious injection related infections among PWID are significant indicators of acute HCV infection.High-priority SSP implementation locations in Florida were identified in both urban and rural communities, including those outside of current

Background Men who have sex with men (MSM) using HIV pre-exposure prophylaxis (PrEP) may be at high risk for bacterial sexually transmitted infections (STIs). We examined the prevalence of extragenital gonorrhea and chlamydia by PrEP status among a multisite sample of US MSM. Methods MSM aged ≥18 years were recruited through venue-based sampling to participate in the 2017 National HIV Behavioral Surveillance. In 5 cities (San Francisco, Washington DC, New York City, Miami, and Houston), participants completed a questionnaire, HIV testing, and pharyngeal and rectal STI specimen self-collection. We measured prevalence of pharyngeal and rectal gonorrhea and chlamydia among self-reported non-HIV-positive MSM who reported using or not using PrEP in the previous 12 months. Results Overall, 29.6% (481/1627) of non-HIV-positive MSM reported PrEP use in the past year. MSM who reported PrEP use were more likely to have any STI (ie, extragenital gonorrhea and/or chlamydia) than MSM not on PrEP [14.6% vs. 12.0%, adjusted prevalence ratio (aPR) = 1.5, 95% confidence interval (CI) : 1.1 to 2.0], reflecting differences in rectal chlamydia prevalence (8.7% vs. 6.0%, aPR = 1.6, 95% CI: 1.1 to 2.4). PrEP use was not associated with pharyngeal chlamydia, pharyngeal gonorrhea, or rectal gonorrhea. Conclusions The prevalence of extragenital STI was high for both MSM on PrEP and those not on PrEP in the past year. MSM on PrEP were more likely to have rectal chlamydia but not pharyngeal STIs or rectal gonorrhea. Our findings support regular STI testing at exposed anatomic sites as recommended for sexually active MSM, including those on PrEP.

Research has shown that HIV-related stigma contributes to people living with HIV having a higher risk of mental health disorders. Our study examines the association between enacted HIV-related stigma and symptoms of anxiety and depression among PLWH. We used baseline data from 932 PLWH collected from the Florida Cohort study between 2014 and 2018. The sample was majority 45 + years of age (63.5%), male (66.0%), and Black (58.1%). The majority had previously experienced enacted HIV-related stigma (53.1%). Additionally, 56.6% and 65.2% showed mild to moderate/severe levels of anxiety and depression, respectively. Those who experienced any levels of enacted HIV-related stigma (vs none) had significantly greater odds of mild and moderate/severe levels of anxiety (vs no/minimal) (AOR[CI] 1.54[1.13, 2.10], p = 0.006; AOR[CI] 3.36[2.14, 5.26], p 0.001, respectively) and depression (AOR[CI] 1.61[1.19, 2.18], p = 0.002; AOR[CI] 3.66[2.32, 5.77], p 0.001, respectively). Findings suggest a need to evaluate interventions for PLWH to reduce the deleterious effects of enacted HIV-related stigma on mental health.Investigaciones previas han documentado que el estigma relacionado con el VIH contribuye al alto riesgo de trastornos de salud mental entre las personas que viven con VIH. Nuestro estudio examina la asociación entre el estigma declarado y síntomas de ansiedad y depresión entre las personas que viven con VIH. Utilizamos datos de referencia recopilados por el “Florida Cohort Study” de 932 personas que viven con VIH. La mayoría de la muestra sobrepasaba 45 años (63.5%), era masculina (66.0%), y racialmente negra (58.1%). La mayoría había experimentado estigma declarado (53.1%). Además, 56.5% y 65.2% mostro niveles de síntomas leves a moderados/severos de ansiedad y depresión, respectivamente. Aquellos que experimentaron cualquier nivel de estigma declarado (vs ninguno) tenían mayores probabilidades de niveles de síntomas leves y moderados/severos de ansiedad (vs ninguno) (ORa[IC] 1.54[1.13, 2.10], p = 0.006; ORa[IC] 3.36[2.14, 5.26], p 0.001, respectivamente) y depresión (ORa[IC] 1.61[1.19, 2.18], p = 0.002; ORa[IC] 3.66[2.32, 5.77], p 0.001, respectivamente). Los resultados sugieren la necesidad de evaluar las intervenciones para las personas que viven con VIH para reducir los efectos nocivos del estigma declarado en la salud mental.

The study objective was to classify women with newly diagnosed HIV into patterns of retention in care (≥2 HIV care visits ≥3 months apart) and viral suppression over time and identify factors associated with class membership. Florida HIV/AIDS surveillance data were used to conduct Latent Class Analysis to classify women into patterns, and multinomial regression was used to compare the prevalence of class membership by demographic and clinical factors. Four classes were selected based on model fit parameters: (Class 1) consistently retained and suppressed (>90% probability of being retained and suppressed), (Class 2) not consistently retained or suppressed (≤10% probability of being retained and suppressed), (Class 3) increasingly retained and suppressed, and (Class 4) decreasingly retained and suppressed. The proportion of women in each class was 48.6%, 24.9%, 14.3%, and 12.2%, respectively. Women aged 25-34 compared to 35-49 years old, injection drug use mode of exposure, US born, and not linked to care three months post-diagnosis had a lower prevalence of belonging to the consistently retained and suppressed class. Findings may be useful in tailoring and targeting interventions to increase the prevalence of women who are consistently retained in care and virally suppressed.

Background Human Immunodeficiency Virus (HIV) disproportionately affects the Southern United States, accounting for approximately 46% of people living with HIV. HIV-related stigma is recognized as a barrier to testing, treatment, and prevention efforts. However, little is known about HIV-related stigma experiences in Florida. Using data collected from the Florida Medical Monitoring Project, we sought to examine individual characteristics associated with HIV-related stigma. Methods We analyzed secondary data from the 2015–2016 Medical Monitoring Project in Florida (n = 603). Stigma was measured using the 10-item HIV Stigma Scale. Exploratory factor analysis of the HIV Stigma Scale revealed three subscales: negative self-image, anticipated, and personalized stigma. Bivariate and multivariate regression models were used to determine the individual characteristics associated with the HIV Stigma Scale. Results Multivariate analysis indicated that people with severe depression scores (OR: 3.13; CI: 1.38–7.13) and persons with disability (OR: 1.64; CI: 1.03–2.61) had significantly increased odds of higher overall stigma. In the subscale analyses, negative self-image was significantly associated with alcohol misuse (OR: 2.02; CI: 1.15–3.56) depression (OR: 2.81; CI: 1.38–5.72) and/or those who identify as homosexual (OR: 0.54; CI: 0.31–0.93). Anticipated stigma was significantly associated with people who had mild-moderate depression (OR: 3.03; CI: 1.20–7.65), severe depression (OR: 2.87; CI: 1.38–5.98), identified as Black (OR: 0.60; CI: 0.37–0.98), non-injection drug use (OR: 0.55; CI: 0.33–0.91), and/or people aged 50 years and older (OR: 0.28; CI: 0.09–0.82). Personalized stigma was not associated with any of the variables examined. Conclusions The implications of these findings reveal that certain individuals are more vulnerable to stigma. Researchers could consider distinct stigma interventions strategies based on the characteristics of specific individuals (i.e., targeting depression, disability, sexual orientation, avoidant coping, racial/ethnic groups, and youth) in Florida.

Purpose This study aimed to estimate the size of the population of men who have sex with men (MSM) in Florida with high-risk behaviors that would indicate eligibility for pre-exposure prophylaxis (PrEP) use. Methods Three methods were used to estimate the MSM population. Estimates from the three methods were averaged, and the number of MSM living with HIV in each zone improvement plan (ZIP) code was subtracted. Results The average MSM estimate was 1–2184 men (1.5–22.9%) by ZIP code. The size of the MSM population with indications for PrEP use was highest when using estimates of MSM with more than one sex partner in the past year obtained from the National HIV Behavioral Surveillance system and lowest when the MSM estimate was multiplied by 24.7% (percentage of MSM with PrEP indications from other studies). Conclusion Areas with high numbers of MSM with PrEP indications could be targeted with information to reduce HIV acquisition.

Highlights • Among PWH, cocaine use vs no-use was associated with worse HIV treatment outcomes. • Powder cocaine only users were more likely to be younger, Hispanic, and employed. • Users of powder + crack cocaine had lower viral suppression than users of either alone. • Harm reduction efforts addressing substance use should be a key component of HIV care., Introduction Cocaine (including powder and crack) use is common among people with HIV (PWH). We identified socio-demographic and behavioral factors associated with cocaine use (overall and various forms) among PWH; we also examined differences in HIV treatment outcomes across cocaine exposure groups. Methods The study sample (N = 1166) was derived from two cohorts of PWH in Florida between 2014 and 2020. Baseline data were linked to the Enhanced HIV/AIDS Reporting System (eHARS) which tracks HIV viral load. Socio-demographics and polysubstance use were compared by cocaine use and the three cocaine use groups (powder only n = 101, crack only n = 91, or both n = 65). The association between the three cocaine use groups, ART adherence, and HIV viral suppression (

Youth aged 13‒24, are less likely to be retained in HIV care and be virally suppressed than older age groups. This study aimed to assess predictors of retention in HIV care and viral suppression among a population-based cohort of youth (N=2,872) diagnosed with HIV between 1993 and 2014 in Florida. We used generalized estimating equations (GEE) to estimate prevalence ratios (PRs). Retention in care was defined as evidence of engagement in care (at least one laboratory test, physician visit, or antiretroviral therapy prescription refill), two or more times, at least three months apart during 2015. Viral suppression was defined as having evidence of a viral load

Introduction Due to the increase in people who use opioids in the US, there has been a steady increase in injection drug use. Without access to safe syringe disposal locations, people who inject drugs (PWID) have few options other than improper disposal, including in public places. In 2016, Florida’s first legal Syringe Services Program (SSP) was established in Miami. This study aims to compare syringe disposal practices among PWID before and after the implementation of an SSP. Methods Visual inspection walkthroughs of randomly selected census blocks in the neighborhoods in the top quartile of narcotics-related arrests were conducted to assess improperly discarded syringes. Syringe location was geocoded in ArcGIS. Adult PWID pre-SSP (n = 448) and post-SSP (n = 482) implementation were recruited for a survey using respondent-driven sampling in Miami. A Poisson regression model was used to determine the adjusted relative risk (aRR) of improper syringe disposal pre- and post-SSP. Results A total of 191 syringes/1000 blocks were found post-implementation versus 371/1000 blocks pre-implementation, representing a 49% decrease after SSP implementation. In the surveys, 70% reported any improper syringe disposal post-SSP implementation versus 97% pre-SSP implementation. PWID in the post-implementation survey had 39% lower adjusted relative risk (aRR = 0.613; 95% CI = 0.546, 0.689) of improper syringe disposal as compared to pre-implementation. Conclusions There was a significant decrease in the number of improperly discarded syringes in public in Miami after the implementation of an SSP. Providing PWID with proper disposal venues such as an SSP could decrease public disposal in other communities.

We reviewed all cases of syphilis reported among pregnant women in Florida during 2018 for syphilitic reinfection. Nineteen (7.3%) of 261 pregnant women with syphilis were reported as reinfected during the same pregnancy. Timely rescreening and treatment prevented six (31.6%) of nineteen reinfected women from delivering infants with congenital syphilis.

The present study examines the HIV continuum of care outcomes among people living with HIV (PLWH) who have either recent (< 12-months) or distal (> 12-months) incarceration history compared to those without an incarceration history. A self-administered survey (as part of the Florida Cohort Study (n=932)) was used to collect data on demographic information, linkage to care, retention in care, HIV medication adherence, viral suppression, and incarceration history. Those with recent incarceration history were least likely to report HIV medication adherence greater than or equal to 95% of the time (χ(2) = 8.79; p=0.0124), always take their medications as directed (χ(2) = 15.29; p=0.0005), and to have durable viral suppression (χ(2) = 16.65; p=0.0002) compared to those distally or never incarcerated. In multivariable analyses, those never and distally incarcerated had greater odds of care linkage ([vs recently incarcerated] AOR=2.58; CI: 1.31, 5.07; p=0.0063, AOR=2.09; CI: 1.11, 3.95; p=0.0228, respectively). Those never incarcerated had greater odds of taking ART as directed ([vs recently incarcerated] AOR = 2.53; CI: 1.23 – 5.19; p=0.0116). PLWH with an incarceration history may need more on-going monitoring and follow-up HIV care than those without previous incarceration regardless of when incarceration occurred.

Background: Although evidence suggests HIV-related stigma directly affects health and behaviors, we have a limited understanding of stigma’s influence beyond the individual-level. We aimed to describe HIV-related stigma and strategies to reduce it in the Southeastern U.S. within the context of the social ecological model (SEM). Methods: Qualitative surveys were distributed in-person at community events, conferences, and via email to persons affected by HIV periodically over 8 months. The final sample size included 87 participants (33 persons living with HIV, 54 without HIV). A directed content analysis was used to code responses into five levels of the SEM (individual, interpersonal, community, institutional, and structural). Results: Multiple themes emerged within each level: Individual – knowledge, fear, internalization; Interpersonal – social network; Community – judgements, discrimination, community organizations, norms; Institutional – competent providers, healthcare services; and Structural – systemic barriers, language, education. Conclusions: The findings exemplify the need for a multi-level approach to intervene and reduce HIV-related stigma. Based on the experiences and suggestions of people affected by HIV, future interventions should include substantial consideration from persons affected by HIV.

Identifying gay neighborhoods could help in targeting HIV prevention efforts for men who have sex with men. This study's purpose was to identify gay neighborhoods using latent class analysis (LCA). Data at the ZIP code level were drawn from the American Community Survey, website lists of gay bars and neighborhoods, and the Florida Department of Health HIV surveillance system. A two-class model was selected based on fit. About 9% of the ZIP code data was in class two, which was designated as gay neighborhoods. Cohen's kappa coefficient was used to examine agreement between the classification of ZIP codes from LCA and websites. Fair agreement was found (0.2501). Gay neighborhoods could serve as a place to disseminate information about pre-exposure prophylaxis and other methods for HIV prevention. Improved measures, such as the planned question about same-sex spouses for the 2020 US Census, are needed to identify gay neighborhoods in population-level surveys.

Molecular HIV surveillance is a promising public health strategy for curbing the HIV epidemic. Clustering technologies used by health departments to date are limited in their ability to infer/forecast cluster growth trajectories. Resolution of the spatiotemporal dynamics of clusters, through phylodynamic and phylogeographic modelling, is one potential strategy to develop a forecasting tool, however, the projected utility of this approach needs assessment. Prior to incorporating novel phylodynamic-based molecular surveillance tools, we sought to identify possible issues related to their feasibility, acceptability, interpretation, and utility. Qualitative data were collected via focus groups among field experts (n = 17, 52.9% female) using semi-structured, open-ended questions. Data were coded using an iterative process, first through the development of provisional themes and subthemes, followed by independent line-by-line coding by two coders. Most participants routinely used molecular methods for HIV surveillance. All agreed that linking molecular sequences to epidemiological data is important for improving HIV surveillance. We found that, in addition to methodological challenges, a variety of implementation barriers are expected in relation to the uptake of phylodynamic methods for HIV surveillance. The participants identified several opportunities to enhance current methods, as well as increase the usability and utility of promising works-in-progress.

Background Persons living with human immunodeficiency virus (HIV) with resistance to antiretroviral therapy are vulnerable to adverse HIV-related health outcomes and can contribute to transmission of HIV drug resistance (HIVDR) when nonvirally suppressed. The degree to which HIVDR contributes to disease burden in Florida—the US state with the highest HIV incidence– is unknown. Methods We explored sociodemographic, ecological, and spatiotemporal associations of HIVDR. HIV-1 sequences (n = 34 447) collected during 2012–2017 were obtained from the Florida Department of Health. HIVDR was categorized by resistance class, including resistance to nucleoside reverse-transcriptase , nonnucleoside reverse-transcriptase , protease , and integrase inhibitors. Multidrug resistance and transmitted drug resistance were also evaluated. Multivariable fixed-effects logistic regression models were fitted to associate individual- and county-level sociodemographic and ecological health indicators with HIVDR. Results The HIVDR prevalence was 19.2% (nucleoside reverse-transcriptase inhibitor resistance), 29.7% (nonnucleoside reverse-transcriptase inhibitor resistance), 6.6% (protease inhibitor resistance), 23.5% (transmitted drug resistance), 13.2% (multidrug resistance), and 8.2% (integrase strand transfer inhibitor resistance), with significant variation by Florida county. Individuals who were older, black, or acquired HIV through mother-to-child transmission had significantly higher odds of HIVDR. HIVDR was linked to counties with lower socioeconomic status, higher rates of unemployment, and poor mental health. Conclusions Our findings indicate that HIVDR prevalence is higher in Florida than aggregate North American estimates with significant geographic and socioecological heterogeneity.

Among people living with HIV (PLWH) in Florida

In 2013, Florida had the highest rate of new HIV infections and only 56% of persons living with HIV (PLWH) were virally suppressed. In response, we initiated a new HIV cohort in Florida to better understand issues affecting HIV health outcomes including viral suppression. The objectives of this paper are to describe the study procedures for the Florida Cohort; summarize information regarding enrollment, follow-up, and findings to date; and discuss challenges and lessons learned regarding the establishment of a new, multisite cohort of PLWH. Florida Cohort participants were enrolled from clinics and community-based organizations in eight geographically diverse counties across Florida. Data were obtained from participant questionnaires, medical records, and state surveillance data that are updated annually. From 2014 to 2018, 932 PLWH (mean age 46.7±11.2 years, 64% male, 55% black, 20% Latinx) were enrolled; 61% (n=569) completed follow-up questionnaires >=6 months after enrollment. At baseline, 83% were retained in care and 75% had HIV viral suppression. Research findings to date have focused on outcomes such as HIV viral suppression, antiretroviral therapy adherence, HIV-related comorbidities, alcohol and drug use, and interest in mHealth interventions. Strengths of the study include the diversity of the sample and the linkage of participant surveys with existing surveillance data. However, the research data are affected by several challenges and decisions made during study planning and follow-up, including issues related to sampling strategy and recruitment location. The lessons learned from this study can be helpful when initiating a new longitudinal cohort study.

Background People who inject drugs (PWID) lag behind other key populations in HIV care continuum outcomes. The impacts of criminal justice reform and increasing drug treatment access on HIV have been underexplored. Methods We developed agent-based models (ABM) of sexual partnerships among PWID and non-PWID, and injection equipment-sharing partnerships among PWID in five US cities (Baltimore, Boston, Miami, New York City, San Francisco) over 3 years. The first set of ABM projected changes in partnership discordance among PWID as a function of decreasing ZIP code-level incarceration rates. The second set projected discordance as a function of increasing ZIP code-level drug treatment access. ABM were parameterized and validated overall, and by city and PWID race/ethnicity (Black, Latino, White) using National HIV Behavioral Surveillance data, administrative ZIP code-level data, surveillance reports and prior literature. Informed by research on prisoner release and community-level HIV prevalence, reductions in incarceration rates were fixed at 5% and 30% and respectively projected to increase ZIP code-level HIV prevalence by 2% and 12%. Increases in drug treatment access were fixed at 30% and 58%. Results In each city, a 30% reduction in ZIP code-level incarceration rates and 12% increase in ZIP code-level HIV prevalence significantly increased sero-discordance among at least one racial/ethnic group of PWID by 1–3 percentage points. A 5% reduction in incarceration rates, and 30% and 58% increases in drug treatment access, led to isolated significant changes in sero-discordance among Black and White PWID that were less than 1 percentage point. Conclusion Reductions in incarceration rates may lead to short-term increases in sero-discordant partnerships among some PWID by increasing community-level HIV prevalence. Efforts to increase HIV testing, engagement in care and community reintegration post release, should be strengthened in the wake of incarceration reform. Additional research should confirm these findings and explore the lack of widespread impacts of drug treatment in this study.

Background: Evidence regarding the association between HIV viral load (VL) and hypertension is inconsistent. In this study, we investigated the relationship using viremia copy-years (VCY), a cumulative measure of HIV plasma viral burden. Methods: Data were analyzed for 686 PLWH in the Florida Cohort Study, who had at least five years of VL data before the baseline. VL data were extracted from Enhanced HIV/AIDS Reporting System (eHARS) and used to define peak VL (pVL), recent VL (rVL), and undetectable VL (uVL: rVL5.7) for analysis. Hypertension was determined based on hypertension diagnosis from medical records. Multivariable logistic regression was used for association analysis. Results: Of the total sample, 277 (40.4%) participants were hypertensive. Compared to the participants with lowest VCY (≤2.7 log10 copy × years/mL), the odds ratios (OR) and 95% confidence interval [95% CI] for hypertension of the remaining four groups, in order, were 1.91 [1.11, 3.29], 1.91 [1.03, 3.53], 2.27 [1.29, 3.99], and 1.25 [0.65, 2.42], respectively, controlling for confounders. The association was independent of pVL, rVL, and uVL, each of which was not significantly associated with hypertension. Conclusion: Persistent HIV infection is a risk factor for hypertension among PLWH. Information provided by VCY is more effective than single time-point VL measures in investigating HIV infection- hypertension relationship. The findings of this study support the significance of continuous viral suppression in hypertension prevention among PLWH.

Prevention of HIV outbreaks among people who inject drugs remains a challenge to ending the HIV epidemic in the United States. The first legal syringe services program (SSP) in Florida implemented routine screening in 2018 leading to the identification of ten anonymous HIV seroconversions. The SSP collaborated with the Department of Health to conduct an epidemiologic investigation. All seven acute HIV seroconversions were linked to care (86% within 30 days) and achieved viral suppression (mean 70 days). Six of the seven individuals are epidemiologically and/or socially linked to at least two other seroconversions. Analysis of the HIV genotypes revealed that two individuals are connected molecularly at 0.5% genetic distance. We identified a risk network with complex transmission dynamics that could not be explained by epidemiological methods or molecular analyses alone. Providing wrap-around services through the SSP, including routine screening, intensive linkage and patient navigation, could be an effective model for achieving viral suppression for people who inject drugs.

Background Data-to-Care (D2C) programming is an important strategy in locating and relinking persons with HIV who are not in care (NIC), back to care. However, Health Department D2C programs have found a large proportion of individuals who seem NIC are living outside of their jurisdiction. Jurisdictions are limited in ability to cross-communicate regarding such individuals. Setting Two D2C programs [New York State (NYS) and Florida (FL)] funded through the Partnerships-for-Care Demonstration Project, partnered to conduct a feasibility pilot project to test cross-jurisdictional D2C reciprocity. Methods Jurisdictions made efforts to set up infrastructure for cross-jurisdictional D2C, and NYS worked to identify persons reported in NYS presumed in need of linkage/relinkage efforts in FL using 3 years of NYS D2C program outcomes. Results One hundred forty NYS NIC individuals were presumed to need linkage/relinkage efforts in FL. However, case dispositions for these individuals were not able to be advanced beyond determining HIV care status due to 4 critical challenges: (1) Local legal and regulatory permissibility for sharing identifiable HIV surveillance information outside of a specific jurisdiction varies; (2) Electronic infrastructure in place does not support public health follow-up of individuals who are not within a jurisdiction's HIV surveillance system; (3) An individual's verifiable current residence is not easily attained; and (4) Roles, responsibilities, and case prioritization within each state, and across jurisdictions vary and require clear delineation. Conclusions Although programmatic challenges during this D2C feasibility pilot project were unsurmountable for NYS and FL, potential solutions presented may facilitate broader national cross-jurisdictional D2C reciprocity.

From 2011–2015, new HIV diagnoses in the United States (US) decreased among most risk groups, but increased 14% among Latino men who have sex with men (MSM). The study’s objective was to assess temporal changes in the distribution of birth country and age among newly diagnosed Latino MSM in Florida. We used records from Hispanics/Latinos who met the Centers for Disease Control and Prevention HIV case definition over a 10-year period (2007–2016) and were reported to the Florida Department of Health HIV/AIDS surveillance system. SAS was used to compare trends in birth country/region and age by year using a two-sided Cochran-Armitage Trend Test. Of 12,427 new diagnoses among all Latinos (men and women) 2007–2016 in Florida, 10,671 were among men (85.9%). Of diagnoses among men, 8,488 (79.5%) were MSM. The proportion of diagnoses among men attributable to MSM increased from 70.0% in 2007 to 85.7% in 2016 (p-value

INTRODUCTION: The accuracy and value of SARS CoV-2 antibody (Ab) testing has been controversial Explanations for negative follow-up Ab tests (Ab-) in PCR+ persons could be poor assays/techniques or entirely absent, transient or delayed COVID-19 Ab responses However, prior corona virus experiences have paradoxically indicated Ab- testing among younger persons and those with milder illness The purpose here was to evaluate if age or illness severity correlate with Ab- assays in persons with prior COVID-19 PCR+ tests METHODS: Part of an on-going study, 2 dissimilar EMS agencies (fire-based vs 3rd service) in 2 far-distanced U S cities with contrasting populations, both evaluated prior PCR+ employees with IgM/IgG testing, but each used 2 different lateral flow chromatographic immunoassay (LFCIA) products Among 70 volunteers at Site 1, 39 were a reference group (RG) from the general population with no prior COVID-19 symptoms or testing (Sx-/NoPCR group) The other 48 (PCR+) principals at both sites had prior nasal swab PCR+ tests At a later date (2-8 weeks), the 48 received IgM/IgG fingerstick LFCIA testing and were surveyed (both sites) for pre-selected Sx categories, illness severity indicators, age, sex and date of PCR+ test RESULTS: Despite distinct differences in local demographics, agencies and assay products, findings were strikingly similar at both sites Of 48 prior PCR+ subjects, roughly 30% at either site (n=15/48;31 2%) were IgM-/IgG- (32 2% at site 1;29 4% at site 2) The mean age for the Sx-/NoPCR RG (n=39, all testing Ab-) was 45 51 yrs, range (R) 26-75 and similarly 43 97 (R=21- 81) for 33 PCR+/Ab+ subjects (p=NS) However, for those with prior PCR+ tests but Ab-, the mean age was 33 9 yrs (R=21-50);2-tailed p=0 009 vs PCR+/Ab+ and 0 003 vs RG Differences were near-identical within each site: Site 1 = 44 7 yrs, R=21-81 vs 34 7 R=21-50 (p=0 048;0 021 vs RG);Site 2: 42 75, R 25-62 vs 32 2, R=27-39 (p=0 048;0 003 vs RG) At both sites, trends were evolving for Ab- in milder disease, women and shorter PCR to Ab testing intervals CONCLUSIONS: Using different IgM/IgG LFCIA products in two highly-contrasted settings, 30% of persons with prior COVID-19 PCR+ tests were Ab- at both sites and, in either venue, those PCR+/Ab- persons were significantly younger than PCR+/Ab+ counterparts

Background Personal networks can influence behaviors, beliefs, attitudes, and values through contact and communication. The University of Miami Mobile PrEP Program offers low-barrier pre-exposure prophylaxis (PrEP)/HIV prevention services through a mobile clinic in five highly impacted neighborhoods in Miami-Dade, the county with the highest HIV incidence in the US. The highest rates are among black and Latino men who have sex with men (MSM). The goal of this study is to understand the acceptability and feasibility of expanding the reach of testing through our clients’ friendship and sexual networks. Methods This study was implemented in five locations across Miami from December 2019 to February 2020. During scheduled PrEP quarterly follow-up clinic visits, participants were offered Ora-Quick oral fluid self test (ST) kits, free of cost for distribution to up to four sexual partners and/or friends. In addition to the information available in the testing kit, brief training regarding the test and resources for post-test engagement were provided. A survey evaluated participants’ distribution plan, comfort level and concerns in offering the test kits to friends/sexual partners. Descriptive statistics included frequencies for categorical variables, and means and ranges for continuous variables. Results A total of 84 participants were offered the ST kits, of which 49 (58%) accepted. Of those accepting kits, 40 (81.63%) of 49 were Latino MSM. Participants requested an average of 3 (mean=2.9, range 1-4) kits, for a total of 144 kits. Overall, 41(84%) felt very comfortable and 47(96%) indicated they felt very comfortable offering this test to their friends/sexual partners. Also, 29(59.2%) planned to distribute kits only to friends, 2(4%) only to sexual partners, 11(22.4%) to both sexual partners and friends and 7(14.2%) to either family or self-test to provide ‘moral support’ to those taking the test. None of the participants expressed any concerns about offering kits to friends or sexual partners. Conclusion Distribution of home based self-test HIV kits through current Mobile PrEP clients’ friendship and sexual networks is acceptable and feasible. Similar social network strategies may be considered to expand reach of HIV testing and PrEP engagement to those with barriers to care. Disclosures All Authors: No reported disclosures

The objective of this study was to estimate disparities in linkage to human immunodeficiency virus (HIV) care among Latinos by country/region of birth, HIV testing site, and neighborhood characteristics. A retrospective study was conducted using Florida HIV surveillance records of Latinos/Hispanics aged 13 diagnosed during 2014-2015. Linkage to HIV care was defined as a laboratory test (HIV viral load or CD4) within 3 months of HIV diagnosis. Multi-level Poisson regression models were used to estimate adjusted prevalence ratios (aPR) for nonlinkage to care. Of 2659 Latinos, 18.8% were not linked to care within 3 months. Compared with Latinos born in mainland United States, those born in Cuba [aPR 0.60, 95% confidence interval (CI) 0.47-0.76] and Puerto Rico (aPR 0.61, 95% CI 0.41-0.90) had a decreased prevalence of nonlinkage. Latinos diagnosed at blood banks (aPR 2.34, 95% CI 1.75-3.12), HIV case management and screening facilities (aPR 1.76, 95% CI 1.46-2.14), and hospitals (aPR 1.42, 95% CI 1.03-1.96) had an increased prevalence of nonlinkage compared with outpatient general, infectious disease, and tuberculosis/sexually transmitted diseases/family planning clinics. Latinos who resided in the lowest (aPR 1.57, 95% CI 1.19-2.07) and third lowest (aPR 1.33, 95% CI 1.01-1.76) quartiles of neighborhood socioeconomic status compared with the highest quartile were at increased prevalence. Latinos who resided in neighborhoods with
