The gelection of the vllIages for EPI evaluation in t,he Western zoneis revLewed taktn6 lnto cone,LderaELon for the, first time the comlng of a drug,fvermectln, gultable for mase treatment. The wideepread use of thie drug, by reduclng mf loads in skin and eyes will spoil any posetbtlity of longltudinal EPf evaluatlon. The prevlous system of selection aimed at evaluatlng the. s,ucce8s or fallure of the vector control effort becomes obsolete and a new system based on a rePresentat,ive sample aimed at describing the conjoint effect of vector contrcl anc'm€ss treat,ment, w111 replace Lt,. For feed back on vect,or contrcl fai.lure EPI will try afLer 6 yeara of Ereatment Lhe fast assessment method use{ ln Perdi6, Goreba Somum and the Kulpawn. Special studies will continue unmodified anc', in the n(:ar future will focus on cc,Llection of dat,a tohelp VCU delimlt the borders of the treatm€,nt area. This st,udies will be conducted ln the' south"and West of Guinea and the North of Mali.
