Abstract

Insecticide treated nets (ITNs) represent a powerful means for controlling malaria in Africa because the mosquito vectors feed primarily indoors at night. The proportion of human exposure that occurs indoors, when people are asleep and can conveniently use ITNs, is therefore very high. Recent evidence suggests behavioral changes by malaria mosquito populations to avoid contact with ITNs by feeding outdoors in the early evening. We adapt an established mathematical model of mosquito behavior and malaria transmission to illustrate how ITNs can achieve communal suppression of malaria transmission exposure, even where mosquito evade them and personal protection is modest. We also review recent reports from Tanzania to show that conventional mosquito behavior measures can underestimate the potential of ITNs because they ignore the importance of human movements.

  • When one considers the human population at risk of transmission outdoors, the niche for spatial repellents becomes increasingly evident due to the lack of current control products for those humans becoming infected in these areas.

    “When one considers the human population at risk of transmission outdoors, the niche for spatial repellents becomes increasingly evident due to the lack of current control products for those humans becoming infected in these areas [34,35] (Figure 3).”

    From Spatial repellents: from discovery and development to evidence-based validation (2012) · cites this paper as [34]

    The indexed passage labeled Abstract says spatial repellents may be needed for outdoor bites in the morning or early evening, supporting a potential role for them. It does not support the claimed lack of current control products: the same passage says repellents should supplement ITNs, which can provide community-level protection even when mosquitoes feed outdoors.

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.
