BACKGROUND & OBJECTIVES The distribution of insecticide-treated bednets (ITNs), as an alternative to untreated bednets or no bednet at all, not only directly prevents the mosquito from biting an individual, but kills the mosquito as well. This reduces the mosquito infestation at the household and community levels. However, barriers may exist limiting the effectiveness of malaria prevention by t...
Many malaria vector mosquitoes in Africa have an extreme preference for feeding on humans. This specialization allows them to sustain much higher levels of transmission than elsewhere, but there is little understanding of the evolutionary forces that drive this behaviour. In Tanzania, we used a semi-field system to test whether the well-documented preferences of the vectors, Anopheles arabiensi...
BACKGROUND Kabul, Afghanistan, is the largest focus of anthroponotic cutaneous leishmaniasis (ACL) in the world. ACL is a protozoan disease transmitted to humans by the bite of phlebotomine sand flies. Although not fatal, ACL can lead to considerable stigmatization of affected populations. METHODS Using data from a standardized survey of 872 households in 4 wards of Kabul, Afghanistan, univar...
A randomized, placebo-controlled treatment trial was conducted among 546 anemic (hemoglobin concentration, 7-11 g/dL) children aged 2-36 months in an area with intense malaria transmission in western Kenya. All children used bednets and received a single dose of sulfadoxine-pyrimethamine (SP) on enrollment, followed by either intermittent preventive treatment (IPT) with SP at 4 and 8 weeks and ...
BACKGROUND Cost-sharing schemes incorporating modest targeted subsidies have promoted insecticide-treated nets (ITNs) for malaria prevention in the Kilombero Valley, southern Tanzania, since 1996. Here we evaluate resulting changes in bednet coverage and malaria transmission. METHODS Bednets were sold through local agents at fixed prices representing a 34% subsidy relative to full delivery co...
Background Insecticide-treated bednets (ITNs) are recommended for use by 3.4 billion people at risk of malaria world-wide. Policy makers rely on measurements of ITN use to optimize malaria prevention efforts. Self-reports are the most common means of assessing ITN use, but self-reports may be biased in a way that reduces their reliability as a proxy for ITN adherence. This meta-analysis compare...
BACKGROUND High levels of insecticide treated bednet (ITN) use reduce malaria burden in countries with intense transmission such as Malawi. Since 2007 Malawi has implemented free health facility-based ITN distribution for pregnant women and children <5 years old (under-5s). We evaluated the progress of this targeted approach toward achieving universal ITN coverage. METHODS We conducted a cros...
