The recent decline of malaria transmission in central-western of Senegal after a scaling up of control measures gives an open window for interventions toward malaria elimination. As a consequence, malaria transmission is now occurring as hotspots. The aim of the project is to evaluate whether target control measures combining indoor residual spraying (IRS) with chemoprophylaxis can virtually eliminate malaria in hotspots. Targeted villages located in four (4) health districts (Mbour, Fatick, Niakhar and Bambey) were sprayed in august 2013 with Actellic® 300 CS (Pirimiphosmethyl). Our objective in this study is to evaluate the acceptability of IRS in the population. IRS is a very complex intervention that requires strong adhesion of populations. After its implementation, 370 households have been interviewed. The results of this survey showed good acceptability of IRS using Actellic® 300 CS, with 97.8% of beneficiaries who declared that IRS is good and even excellent for the community. Despite inconveniences that may arise during intervention, including the preparation of structures to be treated, 98% of respondents were not disturbed in their daily activities. 98.6% of responders declared that sprayers were working with professionalism and almost all households (99.7%) are willing to accept IRS next year. The survey revealed a good acceptability of indoor residual spraying in hot spots located in central-western of Senegal; spraying with Actellic® 300 CS did not cause a problem to the targeted populations. Finally, there is great satisfaction in the population due a huge reduction of mosquito nuisances.
