Insecticide-treated nets provide protection against malaria to children in an area of insecticide resistance in Southern Benin
Open accessAbstract
BACKGROUND: Malaria control is heavily reliant on insecticides, especially pyrethroids. Resistance of mosquitoes to insecticides may threaten the effectiveness of insecticide-based vector control and lead to a resurgence of malaria in Africa. METHODS: In 21 villages in Southern Benin with high levels of insecticide resistance, the resistance status of local vectors was measured at the same time as the prevalence of malaria infection in resident children. RESULTS: Children who used LLINs had lower levels of malaria infection [odds ratio = 0.76 (95% CI 0.59, 0.98, p = 0.033)]. There was no evidence that the effectiveness of nets was different in high and low resistance locations (p = 0.513). There was no association between village level resistance and village level malaria prevalence (p = 0.999). CONCLUSIONS: LLINs continue to offer individual protection against malaria infection in an area of high resistance. Insecticide resistance is not a reason to stop efforts to increase coverage of LLINs in Africa.

The longitudinal study completed in four African countries (Benin, Cameroon, Kenya and Sudan) in 2016 found no association between resistance and malaria prevalence where LLIN use was high.
“The longitudinal study was completed in four African countries (Benin, Cameroon, Kenya and Sudan) in 2016 and found no association between resistance and malaria prevalence where LLIN use was high [42].”
From Mapping insecticide resistance in Anopheles gambiae (s.l.) from Côte d'Ivoire (2018) · cites this paper as [42]
The Discussion reports no association between resistance and malaria prevalence where LLIN use was high. But the Methods describe cross-sectional surveys conducted in Benin in July 2015, not a longitudinal study completed across four countries in 2016. The Background mentions a broader five-country investigation but says this paper reports the Benin assessment. (LLM, conf=0.92)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
