Schedule of prevalence monitoring and treatment of PSAC and SAC in Assoni village. Regarding SAC, MDA was realized in 2008 and Schistosoma mansoni prevalence was assessed each year in 1/3 of SAC. From 2009 to 2013, all the children entering their sixth year were treated systematically, as well as SAC who were found to be infected after prevalence monitoring. Since the closure of Ninefesha Hospital in 2013, PNLB has begun to treat SAC attending school. Non-attending school children who were found to be infected after our prevalence assessment were treated on an individual basis. In blue, prevalence assessment or treatment performed by our program; in green treatment performed by PNLB.
