In the Democratic Republic of the Congo (DRC), several epidemics of yellow fever, dengue fever, chikungunya and Zika cases have been reported. In particular, in Kinshasa, the dengue and chikungunya viruses have previously been detected in patients with undifferentiated fevers and several studies have shown entomological transmission indices above the criteria and standards of the World Health Organization (WHO).\n\nThe aim of our study is to implement and evaluate different strategies to control Aedes mosquitoes at different stages of their life cycle in the city of Kinshasa.\n\nIn particular, a before-and-after interventional study will be piloted and tested in the health zone of Kinshasa, with the aim of providing preliminary evidence of the impact of vector control tools.\n\nInterventions will be implemented in 400 households for each arm for 12 months. Before, after and during the interventions, entomological surveys will be conducted in 160 households in each arm to define the density of the vectors. Mosquitoes will be tested for the possible presence of arbovirus RNA (dengue, chikungunya, Zika, yellow fever). During the pre-intervention period, a serological survey for the same diseases transmitted by the Aedes mosquito will be conducted on a sample of 450 people included in two health centers of reference for the health zone of Mont Ngafula 1. A questionnaire will also be administered before and after the intervention implementation to assess the community's knowledge, attitudes and practices towards Aedes mosquito vector control and Aedes-borne diseases.\n\nThe integration of the data collected within the scope of this study will provide an assessment of the feasibility and impact of the tested methods on entomological indicators, as well as determining the exposure and knowledge of Aedes-borne diseases in the Mont Ngafula 1 area.",[100],"Aedes-borne Diseases",[102,103,63],"Vector control","Aedes mosquitoes","2025-05-12",{"date":106,"type":107},"2025-05-20","ACTUAL",{"date":109,"type":107},"2025-03-26",{"date":111,"type":94},"2026-12-31",{"name":5,"class":6},1]
