Abstract

BACKGROUND: Partial mosquito-proofing of houses with screens and ceilings has the potential to reduce indoor densities of malaria mosquitoes. We wish to measure whether it will also reduce indoor densities of vectors of neglected tropical diseases. METHODOLOGY: The main house entry points preferred by anopheline and culicine vectors were determined through controlled experiments using specially designed experimental huts and village houses in Lupiro village, southern Tanzania. The benefit of screening different entry points (eaves, windows and doors) using PVC-coated fibre glass netting material in terms of reduced indoor densities of mosquitoes was evaluated compared to the control. FINDINGS: 23,027 mosquitoes were caught with CDC light traps; 77.9% (17,929) were Anopheles gambiae sensu lato, of which 66.2% were An. arabiensis and 33.8% An. gambiae sensu stricto. The remainder comprised 0.2% (50) An. funestus, 10.2% (2359) Culex spp. and 11.6% (2664) Mansonia spp. Screening eaves reduced densities of Anopheles gambiae s. l. (Relative ratio (RR) = 0.91; 95% CI = 0.84, 0.98; P = 0.01); Mansonia africana (RR = 0.43; 95% CI = 0.26, 0.76; P<0.001) and Mansonia uniformis (RR = 0.37; 95% CI = 0.25, 0.56; P<0.001) but not Culex quinquefasciatus, Cx. univittatus or Cx. theileri. Numbers of these species were reduced by screening windows and doors but this was not significant. SIGNIFICANCE: This study confirms that across Africa, screening eaves protects households against important mosquito vectors of filariasis, Rift Valley Fever and O'Nyong nyong as well as malaria. While full house screening is required to exclude Culex species mosquitoes, screening of eaves alone or fitting ceilings has considerable potential for integrated control of other vectors of filariasis, arbovirus and malaria.

  • Studies evaluating physical barriers (e.g. house screening and untreated bed nets) have shown reduction on disease burden in the absence of vector lethality.

    “Studies evaluating physical barriers (e.g. house screening and untreated bed nets) have shown reduction on disease burden in the absence of vector lethality [20,21].”

    From Spatial repellents: from discovery and development to evidence-based validation (2012) · cites this paper as [21]

    The Introduction reports that houses with closed eaves or ceilings have a lower malaria burden than houses with open eaves or no ceilings. However, this study measured mosquito densities, not disease burden; although the Methods (Ethics) mention providing untreated bed nets to volunteers, the paper does not report a disease-burden reduction from those nets. Pages are not specified in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • A randomized controlled trial where screening houses resulted in a 50% reduction in malaria vectors entering the house, produced a 50% reduction in anaemia in young children.

    “Specifically, a randomized controlled trial where screening houses resulted in a 50% reduction in malaria vectors entering the house, produced a 50% reduction in anaemia in young children.”

    From Spatial repellents: from discovery and development to evidence-based validation (2012) · cites this paper as [21]

    The Results (Table 3; page unavailable) report that screening eaves reduced indoor densities of the malaria vector Anopheles gambiae, but by about 9%, not 50%. The paper did not measure anaemia in children or report a 50% reduction in it. Its References list a separate randomized trial concerning screening and childhood anaemia, without giving that trial’s results. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • In this study, houses were screened with untreated netting and, since they 'repelled' mosquitoes and did not kill them, they were protected in a similar manner to that expected for spatial repellents.

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.
