Effectiveness and uptake of specifically designed sandfly bednets in the prevention of Visceral Leishmaniasis. (BEDNETS)

AIM To demonstrate that the 'sandfly specific' LN (Long-lasting insecticidal Nets) i.e. with a finer mesh in the lower 75cm of the net, are equivalent in the acceptability, uptake and use to the 'traditional' LN tested in the Kalanet project in India and Nepal.

Context:   The study will take place in the control areas of the KALANET project where by the end of 2008 LLIN will be distributed (see protocol KALANET). Specific sandfly nets are LLIN with a finer mesh in the lower 70 cm of the net.

Study-design:   A cluster randomized trial, 13 clusters (each contains more or less 140 houses), random allocation to intervention and control clusters:
  - Intervention area: 7 clusters where the newly designed 'sandfly specific' LLIN will be distributed
- Control area: 6 clusters where the 'traditional' LLIN (PermaNet®) will be distributed.
Observation and semi-structured questionnaire
   -To evaluate the equivalence in uptake and use between the new intervention and the active control. One in the dry and other in the rainy season (May and September 2009). And to assess the durability of LN
  -To evaluate the equivalence in acceptability between both groups. Done with the last questionnaire on uptake and use in September 2009.

2)  Focus Group Discussions (FGD): between January and February 2009 FGD for the KALANET project will be done, and based on these results the convenience of doing FGD for the 'Specific sandfly' LN will be decided.

Expected results: By establishing the evidence of no differences in acceptability, uptake and use of the 'sandfly specific' net compared with the 'traditional' ones. If the 'sandfly specific' net has an equivalent satisfaction level, and a more specific action through the sandfly, with a higher efficacy, it will provide facts in order to take evidence based decisions.
