Methods We describe the first implementation of the cluster grid response strategy carried out in the community during the cholera outbreak in Kinshasa, in which water and hygiene response activities targeted cholera case clusters. Interventions, which focused on emergency water supply, household water treatment and safe storage, home disinfection and hygiene promotion, were organized using a grid approach. We also performed a preliminary community trial study to assess the temporal pattern of the outbreak, before and after response interventions were implemented. Cholera surveillance databases from the Ministry of Health were analyzed to assess the spatiotemporal dynamics of the outbreak using epidemic curves and cartography. Results From January 2017 to November 2018, a total of 1,712 suspected cholera cases were reported in Kinshasa. During this period, the health zones most affected included Binza Météo, Limeté, Kokolo, Kintambo and Kingabwa. Following implementation of the response strategy, the weekly cholera case numbers in Binza Météo, Kintambo and Limeté decreased by an average of 57% in two weeks and 86% in four weeks.
