ABSTRACT
Africa and the United States are both large, heterogeneous geographies with a diverse range of ecologies, climates and mosquito species diversity which contribute to disease transmission and nuisance biting. In the United States, mosquito control is nationally, and regionally coordinated and in so much as the Centers for Disease Control (CDC) provides guidance, the Environmental Protection Agency (EPA) provides pesticide registration, and the states provide legal authority and oversight, the implementation is usually decentralized to the state, county, or city level. Mosquito control operations are organized, in most instances, into fully independent mosquito abatement districts, public works departments, local health departments. In some cases, municipalities engage independent private contractors to undertake mosquito control within their jurisdictions. In sub-Saharan Africa (SSA), where most vector-borne disease endemic countries lie, mosquito control is organized centrally at the national level. In this model, the disease control programmes (national malaria control programmes or national malaria elimination programmes (NMCP/NMEP)) are embedded within the central governments' ministries of health (MoHs) and drive vector control policy development and implementation. Because of the high disease burden and limited resources, the primary endpoint of mosquito control in these settings is reduction of mosquito borne diseases, primarily, malaria. In the United States, however, the endpoint is mosquito control, therefore, significant (or even greater) emphasis is laid on nuisance mosquitoes as much as disease vectors. The authors detail experiences and learnings gathered by the delegation of African vector control professionals that participated in a formal exchange programme initiated by the Pan-African Mosquito Control Association (PAMCA), the University of Notre Dame, and members of the American Mosquito Control Association (AMCA), in the United States between the year 2021 and 2022. The authors highlight the key components of mosquito control operations in the United States and compare them to mosquito control programmes in SSA countries endemic for vector-borne diseases, deriving important lessons that could be useful for vector control in SSA.

Introduction: les déchets d'équipements électriques et électroniques (D3E), avec leurs enjeux sanitaires et environnementaux, sont devenus un problème de santé publique exposant les travailleurs aux composés d'éléments toxiques responsables de (2ème expertise) troubles respiratoires. Objectif: Etudier la relation entre l'exposition professionnelle aux D3E et la survenue des problèmes respiratoires à Bamako en 2019. Matériel et Méthodes : Il s'agissait d'une étude transversale, analytique de 6 mois, menée dans la ville de Bamako en 2019 et concernait 159 manipulateurs de D3E. Les données ont été collectées sur tablette et les analyses univariées et multivariées réalisées sur SPSS version 22 au seuil de significativité de 0,05 avec présentation des Odds Ratio (OR) et leurs intervalles de confiance à 95% (OR[IC95%]). Résultats : La prévalence en général des troubles respiratoires était de 67,3% chez les manipulateurs des D3E. On notait que le retrait du revêtement des fils électroniques (OR[IC95%] =25,93[2,30;291,53]), la perte de poids récente en dehors d'un régime (OR[IC95%] =7,43[1,68;32,85]) et la rareté de lavage des mains avec du savon après les toilettes (OR[IC95%] =11,50[2,07;63,89]) représentaient un risque plus élevé de problèmes respiratoires. Conclusion :Ces résultats montrent que les manipulateurs de D3E ont beaucoup de comportement à risque des problèmes respiratoires. Cette étude pourrait servir à la mise en Åuvre de stratégies visant à réduire l'impact des D3E
Introduction: waste electrical and electronic equipment (WEEE), with its health and environmental issues, has become a public health problem exposing workers to toxic compounds causing respiratory problems. Objective: To study the relationship between professional exposure to WEEE and the occurrence of respiratory problems in Bamako in 2019. Material and Methods: This was a 6-month cross-sectional, analytical study carried out in the city of Bamako in 2019 and involved 159 WEEE manipulators. Data were collected using a tablet (2). Univariate and multivariate analyzes were performed using SPSS version 22 with the significance level of 0.05. Odds Ratio (OR) were presented with their 95% confident interval (OR [95%CI]). Results: The overall prevalence of respiratory disorders was 67.3% among WEEE handlers. It was noted that the removal of the coating of electronic wires (OR [95%CI] =25.93[2.30;291.53]), recent weight loss outside of a diet (OR [95% CI] =7,43[1.68;32.85]) and the infrequent hand washing with soap after the toilet (OR [95% CI] =11.50[2.07; 63.89]) represented a higher risk of (2) breathing problems. Conclusion: These results show that D3E handlers have a lot of risky behavior for respiratory problems. This study could be used to implement strategies to reduce the impact of D3E
