Evaluation of community directed vector control on transmission of Onchocerca volvulus in a Loa loa co-endemic region

This study will pilot the Slash and Clear methodology in an oncho-Loa loa co-endemic setting. Previous pilots in Uganda and Nigeria have demonstrated that this simple strategy of removing breeding sites can result in significant black fly reductions that last for several months. This study will provide important data on the impact of Slash and Clear on black fly biting, and consequently its impact on oncho elimination. Two intervention and one control community will be compared for two years, with repeated measurements being taken of biting rates.
