Adoption of community-based strategies for sustainable vector control and prevention.

ABSTRACT: Community engagement strategies provide tools for sustainable vector-borne disease control. A previous cluster randomized control trial engaged nine intervention communities in seven participatory activities to promote management of the domestic and peri-domestic environment to reduce risk factors for vector-borne Chagas disease. This study aims to assess the adoption of this innovative community-based strategy, which included chickens' management, indoor cleaning practices, and domestic rodent infestation control, using concepts from the Diffusion of Innovations Theory. We used questionnaires and semi-structured interviews to understand perceptions of knowledge gained, intervention adoption level, innovation attributes, and limiting or facilitating factors for adoption. The analysis process focused on five innovation attributes proposed by the Diffusion of Innovations Theory: relative advantage, compatibility, complexity, trialability, and observability. Rodent management was highly adopted by participants, as it had a relative advantage regarding the use of poison and was compatible with local practices. The higher complexity was reduced by offering several types of trapping systems and having practical workshops allowed trialability. Observability was limited because the traps were indoors, but information and traps were shared with neighbors. Chicken management was not as widely adopted due to the higher complexity of the method, and lower compatibility with local practices. Using the concepts proposed by the Diffusion of Innovations Theory helped us to identify the enablers and constraints in the implementation of the Chagas vector control strategy. Based on this experience, community engagement and intersectoral collaboration improve the acceptance and adoption of novel and integrated strategies to improve the prevention and control of neglected diseases.

Project description:Dengue fever is a mosquito-transmitted disease of great public health importance. Dengue lacks adequate vaccine protection and insecticide-based methods of mosquito control are proving increasingly ineffective. Here we review the emerging use of mosquitoes transinfected with the obligate intracellular bacterium Wolbachia pipientis for vector control. Wolbachia often induces cytoplasmic incompatibility in its mosquito hosts, resulting in infertile progeny between an infected male and an uninfected female. Wolbachia infection also suppresses the replication of pathogens in the mosquito, a process known as "pathogen blocking". Two strategies have emerged. The first one releases Wolbachia carriers (both male and female) to replace the wild mosquito population, a process driven by cytoplasmic incompatibility and that becomes irreversible once a threshold is reached. This suppresses disease transmission mainly by pathogen blocking and frequently requires a single intervention. The second strategy floods the field population with an exclusively male population of Wolbachia-carrying mosquitoes to generate infertile hybrid progeny. In this case, transmission suppression depends largely on decreasing the population density of mosquitoes driven by infertility and requires continued mosquito release. The efficacy of both Wolbachia-based approaches has been conclusively demonstrated by randomized and non-randomized studies of deployments across the world. However, results conducted in one setting cannot be directly or easily extrapolated to other settings because dengue incidence is highly affected by the conditions into which the mosquitoes are released. Compared to traditional vector control methods, Wolbachia-based approaches are much more environmentally friendly and can be effective in the medium/long term. On the flip side, they are much more complex and cost-intensive operations, requiring a substantial investment, infrastructure, trained personnel, coordination between agencies, and community engagement. Finally, we discuss recent evidence suggesting that the release of Wolbachia-transinfected mosquitoes has a moderate potential risk of spreading potentially dangerous genes in the environment.

Project description:BackgroundOpioid addiction and overdose is a public health problem in the United States and is expected to remain with substance use increasing due to the COVID-19 pandemic. Communities that approach this issue through multi-sector partnerships experience more positive health outcomes. Understanding motivation for stakeholder engagement in these efforts is essential to successful adoption, implementation, and sustainability particularly in the shifting landscape of needs and resources.MethodsA formative evaluation was conducted on the C.L.E.A.R. Program in Massachusetts, a state heavily impacted by the opioid epidemic. A stakeholder power analysis identified appropriate stakeholders for the study (n = 9). The Consolidated Framework for Implementation Research (CFIR) guided data collection and analysis. Surveys (n = 8) examined perception and attitudes on the program; motivations and communication for engagement; and, benefits and barriers to collaboration. Stakeholder interviews (n = 6) explored the quantitative findings in more detail. Surveys were analyzed using descriptive statistics and a content analysis with deductive approach was conducted for stakeholder interviews. The Diffusion of Innovation (DOI) Theory guided recommendations for communications to engage stakeholders.ResultsAgencies represented a range of sectors and the majority (n = 5) were familiar with the C.L.E.A.R.ProgramDespite the many strengths of the program and existing collaboration, based on the coding densities of each CFIR construct stakeholders identified crucial gaps in the services the program provided and noted that the overall infrastructure of the program could be enhanced. Opportunities for strategic communication to address the stages of DOI align with the gaps identified in the CFIR domains to result in increased agency collaboration and expansion of services into the surrounding communities to ensure sustainability of the C.L.E.A.R.ProgramConclusionsThis study explored factors necessary for ongoing multi-sector collaboration and sustainability of an existing community-based program especially given the changing context from COVID-19. Findings informed both program revisions and communication strategies to promote the program to new and existing collaborating agencies and the community served, and identify effective communication approaches across sectors. This is essential for successful implementation and sustainability of the program, especially as it is adapted and expanded to address post-pandemic times.Trial registrationThis study does not report results of a health care intervention on human participants, however it was reviewed and determined an exempt study with the Boston University Institutional Review Board (IRB #H-42107).

Project description:In this paper, we aim to systematically analyze the effectiveness of community-based interventions (CBIs) for the prevention and control of helminthiasis including soil-transmitted helminthiasis (STH) (ascariasis, hookworms, and trichuriasis), lymphatic filariasis, onchocerciasis, dracunculiasis, and schistosomiasis. We systematically reviewed literature published before May 2013 and included 32 studies in this review. Findings from the meta-analysis suggest that CBIs are effective in reducing the prevalence of STH (RR: 0.45, 95% CI: 0.38, 0.54), schistosomiasis (RR: 0.40, 95% CI: 0.33, 0.50), and STH intensity (SMD: -3.16, 95 CI: -4.28, -2.04). They are also effective in improving mean hemoglobin (SMD: 0.34, 95% CI: 0.20, 0.47) and reducing anemia prevalence (RR: 0.90, 95% CI: 0.85, 0.96). However, it did not have any impact on ferritin, height, weight, low birth weight (LBW), or stillbirths. School-based delivery significantly reduced STH (RR: 0.49, 95% CI: 0.39, 0.63) and schistosomiasis prevalence (RR: 0.50, 95% CI: 0.33, 0.75), STH intensity (SMD: -0.22, 95% CI: -0.26, -0.17), and anemia prevalence (RR: 0.87, 95% CI: 0.81, 0.94). It also improved mean hemoglobin (SMD: 0.24, 95% CI: 0.16, 0.32). We did not find any conclusive evidence from the quantitative synthesis on the relative effectiveness of integrated and non-integrated delivery strategies due to the limited data available for each subgroup. However, the qualitative synthesis from the included studies supports community-based delivery strategies and suggests that integrated prevention and control measures are more effective in achieving greater coverage compared to the routine vertical delivery, albeit it requires an existing strong healthcare infrastructure. Current evidence suggests that effective community-based strategies exist and deliver a range of preventive, promotive, and therapeutic interventions to combat helminthic neglected tropical diseases (NTDs). However, there is a need to implement and evaluate efficient integrated programs with the existing disease control programs on a larger scale throughout resource-limited regions especially to reach the unreachable.
