Assignment:
Topic:
To investigate the relevance of vectors in determining possible factors influencing lymphatic filariasis transmission in "4 hotspots" and control districts after failing third pre Transmission Assessment survey in 4 hotspots district in Sierra Leone.
Objectives
To investigate driving factors that could possibly responsible for the present situation of ongoing lymphatic filariasis transmission in 4 hotspot district in Sierra Leone having undergone several years of mass drug administration
Specific Objectives
1. To establish a system for collecting large numbers of mosquito samples for xenomonitoring, through the development of a community-based vector collection system.
2. To determine the mosquito species composition in the various study districts.
3. To determine the role of different species of mosquitoes in the transmission of lymphatic filariasis in the "hotspot" and control districts.
4. To determine the role and variations in the cibarial armature of different mosquito species in the study communities.
5. To undertake a questionnaire survey to determine compliance to MDA and possession and use of bednets and other vector control measures in the study districts.
