**7. Prospects of prevention on development and spread of IR in malaria vectors in East Africa**

In vector control, constant use of the same insecticide induces resistance selection pressure in small vector population which subsequently spread to the large population. The spread of resistance depends on the frequency of the resistance genes within the vector population. In operational programs, the coverage of LLINs and IRS are most critical to be considered in the prevention of the development and spread of the insecticide resistance. Further, insecticideresistant monitoring plan and management strategy should be developed and implemented to delay the development or spread of resistance.
