Brief Summary
Illegal gold miners in French Guiana, a French overseas territory ('département') located in Amazonia, often carry malaria parasites (up to 46.8%). While the Guiana Shield Region aims at malaria elimination, the high prevalence of Plasmodiumin this hard-to-reach population in conjunction with frequent incorrect use of artemisinin-based anti-malarials could favor the emergence of resistant parasites. Due to geographical and regulatory issues in French Guiana, usual malaria control strategies cannot be implemented in this particular context.Therefore, new strategies targeting this specific population in the forest are required. Numerous discussions among health institutions and scientific partners from French Guiana, Brazil and Suriname have led to an innovative project based on the distribution of kits for self-diagnosis and self-treatment of Plasmodium infections. The kit-distribution will be implemented at "resting sites", which are areas across the border of French Guiana regularly frequented by gold miners. The main objective is to increase the appropriate use and complete malaria treatment after a positive malaria diagnosis with a rapid test, which will be evaluated with before-and-after cross-sectional studies. Monitoring indicators will be collected from health mediators at the time of kit distribution and during subsequent visits, and from illegal gold miners themselves, through a smartphone application. The project funding is multisource, including Ministries of Health of the three countries, WHO/PAHO, and the European Union.
Detailed Description
Background Despite a decrease in the number of cases reported to CIRE "Cellule de l'Institut de Veille Sanitaire", an interregional epidemiological surveillance center, malaria affects many gold miners working illegally in French Guiana. The ORPAL study carried out by CIC "Centre d'Investigation Clinique" (clinical investigation center) in 2015, showed that the prevalence of Plasmodium in illegal gold miners was 22.3%, of which 84% were asymptomatic. Self-medication practices are very common (52.4%) using artemisinin derivatives. Key issues identified: The mobile population of workers in illegal gold mining sites is particularly affected by malaria due to their living and working conditions and as such represents a reservoir of transmission. Their undocumented irregular status and difficult access to health centers makes care from health professionals rare or belated. The use of inadequate drugs, without prior diagnosis and with improper compliance, mainly due to the high cost of treatment on the black market, is common. These non-recommended practices contribute to the risk of emergence of ACT resistance. Knowledge of the disease by illegal gold miners (causes, symptoms, preventive measures and treatment) remains insufficient. Considering the problems, the identified need is to ensure sufficient intervention coverage of appropriate and rapid care, amongst the malaria "reservoir" population, in order to reduce: Malaria transmission and ACT non-compliance; The ensuing risk of P. falciparum resistance to ACT; The morbidity and mortality of illegal workers in gold-mining sites; The working hypothesis is: The free distribution of self-diagnosis and self-treatment kits, together with appropriate training / information, at "resting sites", Brazil and Suriname, would be a strategy relevant to the specific context of French Guiana, and would respond to the identified need. Objectives This study aims to assess a new malaria control strategy targeting gold miners working illegally in French Guiana, based on the distribution of self-diagnosis kits and self-treatment against P. falciparum in cross-border areas. Main objective Increase the part of illegal gold miners in French Guiana who take ACT entirely after a positive rapid diagnostic test. Secondary objectives Improve the use of anti-malarial treatments against P. falciparum appropriately and in compliance with WHO recommendations. Reduce the prevalence of malaria among illegal gold miners in French Guiana. Increase the part of illegal gold miners in French Guiana who: Know malaria, its causes, the symptoms and protection measures. Have a positive attitude towards recommended prevention measures, the use of adequate anti-malarial treatment, and adherence to treatment. Report applying good preventive practices. Project implementation: This project will be carried out in cooperation with Brazil, Suriname and France. It is divided into 2 sections: Part 1: Implementation and monitoring of the intervention Distribution of self-diagnosis and self-treatment kits to people working illegally at gold-mining sites in French Guiana, along with the provision of training. This distribution will take place at resting sites by trained facilitators. Proactive digital collection of data will be conducted by these facilitators and via gold miners themselves through a mobile application. Part 2: Evaluation of the intervention The final evaluation of the project will be carried out in a cross-sectional study "Orpal bis", with a questionnaire on knowledge, attitudes and practices and blood sampling to measure the prevalence of Plasmodium carriers before / after the intervention. The same study (Orpal) was carried out in 2015 along the Surinamese border, and will be carried out before implementation along the Brazilian border. Therefore, it will be a pre-post evaluation. Depending on the results, the sustainability of the action will be determined by the Health Authorities. Duration As a pilot project, the inclusion period for which the data will be processed in the view of determining the potential sustainability is 12 months. The length of the results capitalizing is estimated to be 6 months, during which the intervention will be maintained, in order to avoid any useless gap. Therefore, the total duration of the pilot phase is 18 months.
