While there was some evidence that An. gambiae s.l. sporozoite rates were lower in villages with deltamethrin + PBO LLINs during the high malaria transmission seasons of 2014–2015, there was no reduction in parity rates or indoor resting densities.
long-lasting insecticidal nets (LLINs)
Data generated by this study will strengthen the National Malaria Control Programme’s insecticide resistance management strategy to safeguard continued efficacy of IRS and other malaria control methods in Ethiopia.
Universal coverage of LLINs was inadequate in the study clusters making it difficult for all household members to use an LLIN.
Stage I results achieved better LLINs and household coverage in districts with the newly implemented strategies.
The WHOPES method overestimated total hole area, likely because holes are elongated rather than circular, suggesting further adjustments to the pHI formula may be warranted when considering LLIN replacement strategies.
Household socio-economic status, educational status and knowledge on malaria were important predictors of LLINs ownership.
The low level of reported knowledge on net care and repair, as well as the low level of reported positive perception towards net repair need to be addressed.
LLIN holes were not associated with increased odds of malaria in this study.
The proposed spatial modelling framework presents a rationale for equitable allocation of routine LLINs and could be used for quantification of other maternal and child health commodities applicable in different settings.
Results demonstraed a mean WTP of approximately 55 Cedis (~13 USD). Demand results suggested that at a price which would support full manufacturing cost recovery, a majority of households in the area would be willing to purchase at least one such unit.
