Developing a surveillance framework for the post-elimination phase of the lymphatic filariasis programme in Bangladesh

Developing a surveillance framework for the post-elimination phase of the lymphatic filariasis programme in Bangladesh

Research question

  • Can the micro-stratification of lymphatic filariasis (LF) transmission assessment surveys positive case and clinical case data be used to identify, map and monitor transmission hotspots as part of an enhanced endgame surveillance strategy?
  • Can targeted molecular xenomonitoring detect ongoing transmission [to the same extent as human surveillance] in defined LF transmission hotspots?

 

Study sites

Notes

Notes on sample size: 

Human – 15 hotspot sites within Rangpur district, with a total of 300-350 individuals sampled per site. In total between 4,500-5,250 humans from approximately 1000 HH, (estimating ~5 people/HH) will be surveyed.

Mosquito – 15 hotspot sites (as above) with an average of 5 traps per village. In total 75 trapping sites, with the number per village adjusted based on the population density within each village (i.e. population proportional sampling), as highly populated sites may require more traps than smaller villages/ hamlets. This will be determined once sites are identified.
