Travel surveillance uncovers dengue virus dynamics and introductions in the Caribbean.

Dengue is the most prevalent mosquito-borne viral disease in humans, and cases are continuing to rise globally. In particular, islands in the Caribbean have experienced more frequent outbreaks, and all four dengue virus (DENV) serotypes have been reported in the region, leading to hyperendemicity and increased rates of severe disease. However, there is significant variability regarding virus surveillance and reporting between islands, making it difficult to obtain an accurate understanding of the epidemiological patterns in the Caribbean. To investigate this, we used travel surveillance and genomic epidemiology to reconstruct outbreak dynamics, DENV serotype turnover, and patterns of spread within the region from 2009-2022. We uncovered two recent DENV-3 introductions from Asia, one of which resulted in a large outbreak in Cuba, which was previously under-reported. We also show that while outbreaks can be synchronized between islands, they are often caused by different serotypes. Our study highlights the importance of surveillance of infected travelers to provide a snapshot of local introductions and transmission in areas with limited local surveillance and suggests that the recent DENV-3 introductions may pose a major public health threat in the region.

North-south pathways, emerging variants, and high climate suitability characterize the recent spread of dengue virus serotypes 2 and 3 in the Dominican Republic.

We employ a multidisciplinary approach, integrating genomics and epidemiology, to uncover recent dengue virus transmission dynamics in the Dominican Republic. Our results highlight a previously unknown north-south transmission pathway within the country, with the co-circulation of multiple virus lineages. Additionally, we examine the historical climate data, revealing long-term trends towards higher theoretical potential for dengue transmission due to rising temperatures. These findings provide information for targeted interventions and resource allocation, informing as well towards preparedness strategies for public health agencies in mitigating climate and geo-related dengue risks.

Global health reciprocal innovation to address mental health and well-being: strategies used and lessons learnt.

Over the past two decades there have been major advances in the development of interventions promoting mental health and well-being in low- and middle-income countries (LMIC), including delivery of care by non-specialist providers, incorporation of mobile technologies and development of multilevel community-based interventions. Growing inequities in mental health have led to calls to adopt similar strategies in high-income countries (HIC), learning from LMIC. To overcome shared challenges, it is crucial for projects implementing these strategies in different global settings to learn from one another. Our objective was to examine cases in which mental health and well-being interventions originating in or conceived for LMIC were implemented in the USA. The cases included delivery of psychological interventions by non-specialists, HIV-related stigma reduction programmes, substance use mitigation strategies and interventions to promote parenting skills and family functioning. We summarise commonly used strategies, barriers, benefits and lessons learnt for the transfer of these innovative practices among LMIC and HIC. Common strategies included intervention delivery by non-specialists and use of digital modalities to facilitate training and increase reach. Common barriers included lack of reimbursement mechanisms for care delivered by non-specialists and resistance from professional societies. Despite US investigators' involvement in most of the original research in LMIC, only a few cases directly involved LMIC researchers in US implementation. In order to achieve greater equity in global mental health and well-being, more efforts and targeted funding are needed to develop best practices for global health reciprocal innovation and iterative learning in HIC and LMIC.

Genomic Surveillance of SARS-CoV-2 Variants in the Dominican Republic and Emergence of a Local Lineage.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an RNA virus that evolves over time, leading to new variants. In the current study, we assessed the genomic epidemiology of SARS-CoV-2 in the Dominican Republic. A total of 1149 SARS-CoV-2 complete genome nucleotide sequences from samples collected between March 2020 and mid-February 2022 in the Dominican Republic were obtained from the Global Initiative on Sharing All Influenza Data (GISAID) database. Phylogenetic relationships and evolution rates were analyzed using the maximum likelihood method and the Bayesian Markov chain Monte Carlo (MCMC) approach. The genotyping details (lineages) were obtained using the Pangolin web application. In addition, the web tools Coronapp, and Genome Detective Viral Tools, among others, were used to monitor epidemiological characteristics. Our results show that the most frequent non-synonymous mutation over the study period was D614G. Of the 1149 samples, 870 (75.74%) were classified into 8 relevant variants according to Pangolin/Scorpio. The first Variants Being Monitored (VBM) were detected in December 2020. Meanwhile, in 2021, the variants of concern Delta and Omicron were identified. The mean mutation rate was estimated to be 1.5523 × 10-3 (95% HPD: 1.2358 × 10-3, 1.8635 × 10-3) nucleotide substitutions per site. We also report the emergence of an autochthonous SARS-CoV-2 lineage, B.1.575.2, that circulated from October 2021 to January 2022, in co-circulation with the variants of concern Delta and Omicron. The impact of B.1.575.2 in the Dominican Republic was minimal, but it then expanded rapidly in Spain. A better understanding of viral evolution and genomic surveillance data will help to inform strategies to mitigate the impact on public health.

Health care access and migration experiences among Venezuelan female sex workers living in the Dominican Republic.

Objective: To identify sexual risk behaviors and barriers to sexual and reproductive health care (SRH) among Venezuelan female sex workers living in the Dominican Republic. Methods: This was a mixed-methods study using four focus group discussions (FGDs) and a cross-sectional quantitative survey with Venezuelan migrant female sex workers. The study was conducted from September through October 2021 in two urban areas (Santo Domingo and Puerto Plata) in the Dominican Republic. Information collected from the FGDs was analyzed using thematic content analysis, and quantitative data were analyzed using univariate descriptive statistics. Data analysis was conducted from 30 November 2021 to 20 February 2022. Results: In all, 40 Venezuelan migrant female sex workers with a median (range) age of 33 (19-49) years participated in the FGDs and survey. The FDGs identified barriers to SRH services, including immigration status and its implications for formal employment and health access, mental wellbeing, quality-of-life in the Dominican Republic, navigating sex work, perceptions of sex work, SRH knowledge, and limited social support. Findings of the quantitative analysis indicated that most participants reported feeling depressed (78%), lonely/isolated (75%), and having difficulty sleeping (88%). Participants reported an average of 10 sexual partners in the past 30 days; 55% had engaged in sexual practices while under the influence of alcohol; and only 39% had used a condom when performing oral sex in the past 30 days. Regarding AIDS/HIV, 79% had taken an HIV test in the past 6 months, and 74% knew where to seek HIV services. Conclusions: This mixed-methods study found that nationality and social exclusion have a multilayered influence on migrant female sex workers, sexual risk behaviors, and access to health care. Recommendations for effective evidence-based interventions to address sexual health knowledge need to be implemented to address risky sexual behaviors, improve access to SRH, and reduce affordability barriers.

Adapting and pilot testing an HIV and intersectional stigma reducing intervention for Dominican Republic healthcare contexts: Protocol for translational research.

Background: This protocol details the adaptation and pilot testing of the Finding Respect and Ending Stigma around HIV (FRESH) intervention in Dominican Republic. FRESH is a healthcare setting stigma-reduction intervention designed to reduce stigmas affecting people living with HIV (PLHIV), focusing on HIV and intersectional stigmas experienced by sexual and gender minority (SGM) people living with HIV. After the successful adaptation of the FRESH intervention, it will be pilot-tested through the conduct of a pilot stepped wedge cluster randomized controlled trial. Methods: Three aims are included in this study; Aim 1 includes exploratory qualitative assessment, specifically the conduct four focus groups with men who have sex with men (MSM) living with HIV (n = 24-32) and in-depth interviews with transgender women living with HIV to explore their experiences with stigma in clinics (n = 9-12). In-depth interviews will also be held with HIV healthcare workers to elucidate their perceptions and behaviors towards their SGM clients (n = 9-12). In Aim 2, informed by Aim 1 data, we will use the sequential phases of the ADAPT-ITT framework to iteratively adapt the FRESH intervention for the Dominican Republic. In Aim 3, the adapted intervention will be pilot-tested via a cluster stepped wedge randomized controlled trial to assess feasibility and acceptability of the intervention and study protocols. Conclusions: If this pilot trial is successful, next steps will include testing the adapted intervention across Dominican Republic or in similar Spanish-speaking Caribbean nations in a larger trial to assess effectiveness in reducing stigma in clinical settings towards PLHIV.

Serological Confirmed Syphilis Among Transgender Women in Dominican Republic.

Purpose: Transgender women (TW) in the Dominican Republic (DR) are at high risk for syphillis infection. Although treatable, infection rates remain at epidemic proportions. Methods: In 2016, we conducted a national survey, with serological sampling of TW in the DR (n=255). Results: In our sample, syphillis seropositivity was 47.45%. There was a statistically significant association between age (t=-2.93, df, p<0.01), arrest history (χ 2=8.15, p<0.01), exposure to violence (χ 2=3.73, p<0.05), and syphilis seropositivity. Multivariate analyses show TW arrested in the past 6 months have higher odds of seropositivity (odds ratio=2.05, confidence interval: 1.04-4.06, p<0.05). Conclusions: There is a need for education and public health campaigns focused on TW specifically.

Transgender Women in Dominican Republic: HIV, Stigma, Substances, and Sex Work.

Exposure to stigma, violence, sex work, and substance use are associated with increased HIV risk, but relationships between these factors have not been fully elucidated among transgender women whose data are often aggregated with men who have sex with men and other sexual and gender minorities. Considering this gap, we aimed to identify a serologically confirmed HIV estimate for transgender women and examine the relationships between stigma, sex work, substance use, and HIV among a national sample of transgender women in Dominican Republic. We analyzed biomarkers and self-report data from the third wave of Dominican Republic's Encuesta de Vigilancia y Comportamiento con Vinculación Serológica, employing logistic and negative binomial regression to estimate models (n = 307). HIV rate was 35.8%. Nearly 75% of respondents engaged in sex work. Over 20% reported experiencing violence; 61.6% reported being stigmatized. Participation in sex work was associated with higher levels of stigma [incidence rate ratio (IRR): 1.70, p < 0.05]. Respondents who experienced violence had over three times higher odds of living with HIV relative to respondents who had not been victimized [odds ratio (OR): 3.15, p < 0.05]. Marijuana users were less likely to experience stigma compared with cocaine users (IRR: 1.72, p < 0.05), and a higher risk of alcohol dependency was associated with higher odds of experiencing violence (OR: 1.17, p < 0.001). Findings illustrate the importance of disaggregating data collected from transgender women compared with other sexual and gender minorities to ascertain subpopulation-specific estimates and indicate an urgent need to implement structural interventions and policies to protect transgender women's health and their human rights.

Genome Sequences of Community SARS-CoV-2 B.1.526 and P.1 Variants Circulating in the Dominican Republic.

Nearly complete genome sequences were obtained for a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concern and two variants of interest from nasopharyngeal swab samples obtained during surveillance activities in urban communities, among individuals with no previous travel history, in Santo Domingo, Dominican Republic.

Decolonizing Science Diplomacy: A Case Study of the Dominican Republic's COVID-19 Response.

The COVID-19 pandemic forced healthcare systems globally to handle a dramatic surge in healthcare utilization while also taxing available testing resources. In the context of healthcare systems in Latin America and the Caribbean, COVID-19 added to the existing burden of infectious diseases related to endemic infections such as arboviruses and HIV. In the Dominican Republic, testing is supplied mostly by the private sector and a national public laboratory. The surge in testing demands laid bare a lack of installed capacities both in laboratory facilities and equipment and trained staff in molecular biology laboratory procedures. This article discusses a case of how science diplomacy and a relatively new law fostering public-private partnerships allowed a university to play a major role in public health response while generating knowledge to inform public policy decisions in an unprecedented manner in the country. Science diplomacy is discussed in the context of decolonization and the importance of the local gaze when creating academic partnerships in the context of global health emergencies.

Breeding Sites of Synanthropic Mosquitoes in Zika-Affected Areas of the Dominican Republic.

Mosquito-borne diseases are a major public health concern in the Caribbean. Domestic water-storage containers are preferred breeding habitats for synanthropic mosquito species, among which Aedes aegypti stands out due to its role in arbovirus transmission. To determine the microenvironmental features associated with container-dwelling mosquitoes, a house-to-house cross-sectional entomological survey was carried out in 9 Dominican provinces affected by Zika virus in 2016. All containers with the potential to store water were sampled, all immature mosquitoes were collected, and information on the type, capacity, volume of stored water, building material, presence of flowers, and house location was documented. The specimens were identified and larval indices (House index [HI], Container index [CI], Breteau index [BI], and Ae. aegypti Breeding Percentage) were applied. A total of 665 dwellings were surveyed across 30 neighborhoods. A total of 1,420 water-filled container habitats were sampled, 19.3% of which harbored immature mosquitoes of 5 species, including 4 important vectors. The dominance of Ae. aegypti was marked, as it was present in all sampled neighborhoods, inhabiting 272 containers (19.1%). Larval indices were higher than the threshold values accepted (5% for the HI and BI, and 3% for the CI) in almost all neighborhoods. The presence of Aedes spp. was associated with the serviceability of water-holding containers (χ2 = 16.56522; P < 0.001), and the difference in volume between water-holding containers was associated with the presence of Aedes spp. infection (χ2 = 4; P < 0.001), the containers up to 5 liters being the most infested. This is the first entomological research based on synanthropic mosquito breeding habitats that cover urban areas of the 3 macro-regions of the Dominican Republic.

Transmisión del virus del dengue y su relación con factores climáticos durante los períodos intra e interepidémicos en Santo Domingo, República Dominican / Dengue Virus Transmission and its Relationship with Climatic Factors During Intra and Interepidemic Periodsin Santo Domingo, Dominican Republic

Introducción: Aedes spp. y la dinámica del virus del dengue está altamente influenciada por factores ambientales. Una relación detallada entre el clima y la enfermedad en los períodos inter e intra-epidémicos podrían beneficiar la vigilancia del dengue para optimizar la preparación y las políticas adecuadas de control de vectores. Métodos: se analizaron los informes de casos de dengue y las variables climáticas en Santo Domingo, República Dominicana, para determinar la correlación del período 2012- 2018 y los diferentes tiempos de retraso. Se llevó a cabo un análisis de regresión de dichas variables para comprender mejor las relaciones entre las tasas de incidencia del dengue y los cambios climáticos. Resultados: durante los brotes epidémicos, la temperatura (r = 0.73, p <0.001) y la humedad relativa (r = -0.2, p = 0.009) se correlacionan significativamente con la incidencia del dengue con un retraso de 9 semanas, el análisis de regresión muestra que la temperatura media (b = 62.401, p < 0.001), precipitación (b = 2.810, p <0.001) y humedad relativa (b = -5.462, p = 0.025) fueron predictores significativos. Durante los períodos inter-epidémico, la temperatura (r = 0.23, p <0.001) tuvo una correlación significativa con la incidencia del dengue con un retraso de 7 semanas, la humedad relativa (b = 1.454, p <0.05) y la temperatura media (b = 5.14, p <0.01) son predictores significativos de la cantidad de casos de dengue. La precipitación no se correlacionó significativamente con la incidencia del dengue. Conclusiones: existe una relación no lineal entre los factores climáticos y la incidencia del dengue. La infección por dengue depende del clima, y la temperatura parece jugar un papel importante en los factores climáticos.

Introduction: Aedes spp. and Dengue Virus dynamics are highly influenced by environmental factors. A detailed relationship between climate and disease in inter and intra-epidemic periods may benefit dengue surveillance, preparedness, and adequate vector control policies. Methods: Dengue case reports and climatic variables in Santo Domingo, Dominican Republic, were analyzed for climate variables correlation from the period 2012-2018 and varying lag times. Regression analysis of climatic variables was carried out to better understand significant correlations between dengue incidence rates and changes in climate. Results: During epidemic outbreaks, temperature (r = 0.73, p < 0.001) and relative humidity (r = -0.22, p = 0.009) demonstrated a significant correlation with dengue incidence. Our regression analysis demonstrates an increase 62.4 cases for each degree Celsius increased with a 9-week-lag. Regression analysis also demonstrated mean temperature (b= 62.401, p < 0.001), precipitation (b = 2.810, p < 0.001), and relative humidity (b = -5.462, p = 0.025) to be significant predictors. During inter-epidemic periods, temperature (r = 0.23, p < 0.001) had a significant correlation with dengue incidence with a 7-week-lag, which demonstrates that relative humidity (b = 1.454, p < 0.05), and mean temperature (b = 5.14, p < 0.01) are significant predictors of the quantity of dengue cases. Precipitation did not significantly correlate with dengue incidence. Conclusions: A non-linear relationship between climatic factors and dengue incidence exists in the Dominican Republic. Dengue infection is climate-dependent and temperature seems to play a significant role in climatic factors

Asynchronicity of endemic and emerging mosquito-borne disease outbreaks in the Dominican Republic.

Mosquito-borne viruses threaten the Caribbean due to the region's tropical climate and seasonal reception of international tourists. Outbreaks of chikungunya and Zika have demonstrated the rapidity with which these viruses can spread. Concurrently, dengue fever cases have climbed over the past decade. Sustainable disease control measures are urgently needed to quell virus transmission and prevent future outbreaks. Here, to improve upon current control methods, we analyze temporal and spatial patterns of chikungunya, Zika, and dengue outbreaks reported in the Dominican Republic between 2012 and 2018. The viruses that cause these outbreaks are transmitted by Aedes mosquitoes, which are sensitive to seasonal climatological variability. We evaluate whether climate and the spatio-temporal dynamics of dengue outbreaks could explain patterns of emerging disease outbreaks. We find that emerging disease outbreaks were robust to the climatological and spatio-temporal constraints defining seasonal dengue outbreak dynamics, indicating that constant surveillance is required to prevent future health crises.

Seroprevalence of Specific Antibodies against SARS-CoV-2 from Hotspot Communities in the Dominican Republic.

Seroprevalence surveys are of utmost importance to assess the proportion of a population that has developed antibodies against a newly introduced virus and could therefore potentially exhibit immunologic protection against subsequent infection. This study aims to understand the distribution of IgM and IgG antibodies in the Dominican Republic. We surveyed a total of 12,897 participants between April and June 2020 in 10 provinces of the Dominican Republic. Survey efforts in emerging hotspots yielded a positivity for all participants of anti-SARS-CoV-2 IgM of 3.8% and IgG of 5.4%, indicating that the pathogen was in circulation before the identification of those particular communities as hotspots. We found important age differences between participants who participated in the serological study where a higher mean age is associated IgM positivity and a lower age with IgG positivity. Our results highlight the need for strategies that involve community-based seroprevalence monitoring. These should preclude syndromic case identification. Also, the higher mean age of IgM-positive participants suggests that strategies based on syndromic surveillance could identify hotspots at later phases, based on the number of cases detected at the healthcare center, as such community-based seroprevalence monitoring may be an effective intervention for future outbreaks.

Modelo de Cascada de Atención para la co-infección de las hepatitis virales para el cuidado continuo en personas con VIH/Sida / Care Continuum Model for Coinfection of Viral Hepatitis for the Continuing Care in people living with HIV / AIDS

Introducción: las coinfecciones con hepatitis virales y el VIH representan un riesgo por su alta transmisibilidad y complicaciones. Es de vital importancia que se puedan identificar las barreras de acceso y manejo de las coinfecciones del VIH y la Hepatitis B y C. El propósito del estudio es describir la cascada de atención para la coinfección de las hepatitis virales en personas viviendo con VIH/SIDA. Métodos: se delimitaron los indicadores de manejo y seguimiento de los pacientes monitoreados actualmente en clínicas de primer nivel de atención en Santo Domingo y Santiago. Los datos recopilados fueron analizados a partir de los registros escritos de los pacientes en seguimiento, para evaluar los datos epidemiológicos y serológicos que se obtuvieron de los archivos clínicos. Resultados: se demostró que un 100 % de los pacientes fueron enrolados, 85.7 % se consideraron como retenidos en el manejo de la coinfección VIH/VHB y solamente 71.4 % recibieron TARV basado en Tenofovir. La cascada de atención para la coinfección VIH/VHC muestra un vínculo de 87.5 % de los pacientes, 75 % fueron retenidos y ninguno recibió tratamiento. Conclusión: la identificación de los factores de riesgo que influyen en las brechas de la cascada es fundamental para optimizar el manejo y monitoreo de los pacientes coinfectados, teniendo en cuenta que es preciso poder reconocer aquellos infectados para iniciar tratamiento de inmediato y así prever secuelas citopatológicas hepáticas

Introduction: Co-infections of viral hepatitis and HIV represent a risk due to their high transmissibility and complications. It is vitally important that barriers to access and management of HIV and Hepatitis B and C co-infections can be identified. The purpose of the study is to describe the cascade of attention for the preparation of viral hepatitis in people living with HIV/AIDS. Methods: The management and follow-up indicators of the patients currently monitored in first-level care clinics in Santo Domingo and Santiago were delimited. The data collected was analyzed from the written records of the patients in follow-up to evaluate the epidemiological and serological data that was obtained from the clinical files. Results: It was demonstrated that 100% of the patients were enrolled, 85.7% were considered as retained in care of HIV / HBV coinfection and only 71.4% received ARTbased on Tenofovir. The cascade of care for HIV / HCV coinfection shows a linkage to care of 87.5% of patients, 75% were retained and none received treatment. Conclusions: Identifying the risk factors that influence the gaps in the cascade of care is essential to optimize the management and monitoring of coinfected patients, with special interest in those that might receive immediate treatment to prevent liver cytopathological sequelae

Neurologic injuries following road traffic accidents in the Dominican Republic: Examining causes and potential solutions.

Objective: Road traffic accidents (RTAs) are the number one cause of traumatic brain injuries (TBIs) worldwide. This study examines RTA-related TBIs in the Dominican Republic, a country in the Caribbean with the highest RTA fatality rate in the Western Hemisphere. Methods: We interviewed 117 adult patients or medical guardians of patients admitted to Hospital Traumatológico Dr. Ney Arias Lora in Santo Domingo following an RTA. Information regarding the type of accident, patient demographics, and injuries sustained was collected for each patient. Results: Most study participants were males (79.5%), and the most common method of transportation was motorized 2-wheeled vehicle (MTW; 74.4%). Of the 69 patients who suffered a TBI, 66.7% were classified as moderate-severe TBIs and 30.3% were classified as mild TBIs. The most common types of intracranial hemorrhage were subdural hemorrhage (12%) and subarachnoid hemorrhage (9.4%). Helmet use among admitted MTW riders was reported at 22.4%, and none of the 9 MTW riders who died in the hospital were wearing a helmet. Only 58.1% of patients lived in an area that offered 911 emergency response services at the time of the study. At 66.2%, the majority of people living within the 911 service area utilized emergency response services following an RTA. Multiple logistic regression determined that the utilization of 911 emergency response services was associated with a decrease in the likelihood of presenting with a moderate/severe TBI by a factor of 0.78 (adjusted odds ratio [OR]; P < .008; 95% confidence interval [CI], 0.65, 0.93). Nonuse of a helmet was associated with a 1.22 times increased risk of presenting with a moderate/severe TBI (adjusted OR; P < .04; 95% CI, 1.01, 1.61). Age and gender were not statistically significant in this model. Conclusions: The results of this study support 2 important avenues for reducing the burden of RTA-associated neurologic disease in the Dominican Republic. As with many other middle-income countries, MTWs represent an economical and efficient mode of transportation. Therefore, increasing helmet use may be the most effective way to reduce RTA-associated TBIs. In addition, continuing the expansion of postcrash emergency response services may mitigate the severity of RTA-associated neurologic disease.

Alcohol Use, High Risk Behaviors, and Experiences of Discrimination Among Transgender Women in the Dominican Republic.

Objectives: This study examines associations between alcohol use, high risk sexual behaviors, and experiences of stigma among transgender women across the Dominican Republic. Data from the 2015 Transgender Health Needs Study were analyzed using bivariate analyses (N = 291). Results: High rates of stigma, verbal abuse, alcohol use, and sex work are found and are associated with each other. Almost 45% of regular alcohol users are engaging in sex work (43.6%), compared with 31.1% of the non-regular alcohol users (χ2=4.82, p < .05). Having sex under the influence of alcohol is statistically associated with high risk behaviors, such as engaging in sex work, sometimes or never using a condom when receiving anal sex, and higher numbers of sexual partners. Furthermore, transgender women who have had sex under the influence of alcohol report statistically significantly higher levels of verbal abuse, discrimination, and levels of perceived transgender stigma. Conclusions/Importance: Findings suggest that although anti-discrimination laws exist, policies may not protect transgender women from experiencing stigma and discrimination at work, potentially forcing them to seek alternative careers and engage in behaviors that expose them to greater personal risk and harm. This intersection of factors may indicate a notable public health gap in transgender health in the Dominican Republic.
