Community engagement in mobile and hard-to-reach populations: a community-based intervention for malaria elimination in a tri-national region of the Guiana Shield.

Several countries of the Guiana Shield are aiming at the control and elimination of malaria in areas where Artisanal and Small-scale Gold Mining (ASGM) activities predominate, raising questions about how to strengthen community engagement to improve the effectiveness of health programs. The Curema project focuses its intervention on the mobile and hard-to-reach ASGM population, complementing the efforts of national programs in the Guiana Shield. The Curema intervention combines targeted drug administration for suspected Plasmodium vivax asymptomatic carriers, the Malakit distribution, and health education activities. The primary goals of this manuscript are to outline a pathway to foster community participation in the Curema project aimed at eliminating malaria. Thus, it presents a vision of the challenges that the AGSM community poses in terms of community participation for an asymptomatic problem; and highlights the community-based model and the Information, Education and Communication (IEC) components as foundations for participation. In addition, it also presents culturally sensitive IEC strategies designed through iterative and collaborative consultative processes and other bottom-up outreach activities. The community engagement approach facilitates adaptability and responsiveness in a complex, evolving context increasing the effectiveness of interventions.

Core principles of Malakit intervention for transferability in other contexts.

To eliminate malaria, all populations must be included. For those who are not reached by the health care system, specific interventions must be tailor-made. An innovative Malakit strategy, based on the distribution of self-diagnosis and self-treatment kits, has been evaluated in the Suriname-French Guiana- Amapá (Brazil) region. The results showed effectiveness and good acceptability. The Malakit intervention is complex and has many components. Its transferability requires adaptation to other populations and regions, while retaining the main features of the intervention. This article provides the keys to adapting, implementing and evaluating it in other contexts facing residual malaria in hard-to-reach and/or mobile populations. The process of transferring this intervention includes: diagnosis of the situation (malaria epidemiology, characteristics of the population affected) to define the relevance of the strategy; determination of the stakeholders and the framework of the intervention (research project or public health intervention); adaptation modalities (adaptation of the kit, training, distribution strategy); the role of community health workers and their need for training and supervision. Finally, evaluation needs are specified in relation to prospects for geographical or temporal extension. Malaria elimination is likely to increasingly involve marginalized people due to climate change and displacement of populations. Evaluation of the transferability and effectiveness of the Malakit strategy in new contexts will be essential to increase and refine the evidence of its value, and to decide whether it could be an additional tool in the arsenal recommended in future WHO guidelines.

El Estigma Social Asociado a la Enfermedad de Chagas

Resumen Objetivos: identificar a partir de relatos individuales y familiares los componentes del estigma social asociado a un diagnóstico de Chagas positivo. Métodos: el estudio recopila los testimonios de tres familias a través de entrevistas a profundidad que fueron grabadas, cuyo contenido fue estructurado y luego compartido entre los investigadores a través de un proceso de triangulación. Resultados: se identificaron las diferentes formas de estigma social, experimentado, percibido, anticipado, así como el autoestigma, el estigma por asociación y comportamientos de discriminación; lo que conlleva el aislamiento social, refuerza los miedos tradicionalmente relacionados a esta enfermedad, y provoca tensiones intrafamiliares. El estigma social y el silencio que lo acompaña son serias barreras de acceso a la consulta médica y al tratamiento antiparasitario. Conclusiones: Es importante tomar en cuenta aspectos de tipo psico-socio-cultural en las estrategias de atención integral de Chagas, principalmente en los programas de información, educación, comunicación (IEC) y durante la consulta médica. Para romper el estigma y el silencio que lo acompaña, es indispensable integrar las personas afectadas por Chagas y otros actores de la sociedad civil en el diseño de esas estrategias.

Abstract Objectives: to identify the components of social stigma associated with a positive diagnosis of Chagas disease based on individual and family accounts. Methods: The study compiles the testimonies of 3 families through in-depth interviews that were recorded, the content of which was structured and then shared among the researchers through a process of triangulation. Results: different forms of social stigma, experienced, perceived, anticipated, as well as self-stigma, stigma by association and discriminatory behaviours were identified, leading to social isolation, reinforcing traditional fears associated with the disease, and causing intra-familial tensions. Social stigma and the silence that accompanies it are serious barriers to access to medical consultation and deworming treatment. Conclusions: It is important to take into account psycho-socio-cultural aspects in strategies for comprehensive care of Chagas disease, especially in information, education and communication (IEC) programmes and during the medical consultation. Also, to break the stigma and the silence surrounding it, it's essential to integrate people affected by Chagas and other civil society actors into the conception of these programs.
