Low quality of routine microscopy for malaria at different levels of the health system in Dar es Salaam (Publications)
confirm malaria cases in Tanzania is low and presumptive treatment of malaria is being practiced widely. In malaria endemic areas WHO now recommends systematic laboratory testing when suspecting malaria. Currently [...] Currently, the use of Rapid Diagnostic Tests (RDTs) is recommended for the diagnosis of malaria in lower level peripheral facilities, but not in health centres and hospitals. In this study, the following [...] quality of routine microscopy, and (2) the effects of RDT...
Malaria treatment in the retail sector: knowledge and practices of drug sellers in rural Tanzania (Publications)
of Kilombero and Ulanga, Tanzania, we interviewed 489 shopkeepers about their knowledge of malaria and malaria treatment. A complementary mystery shoppers study was conducted in 118 retail outlets in order [...] general shops. RESULTS: Shopkeepers in drug stores were able to name more malaria symptoms and were more knowledgeable about malaria treatment than their peers in general shops. In drug stores, 52% mentioned [...] case. CONCLUSIONS: The quality of malaria case-management in the retail...
Estimating the burden of malaria in Senegal: Bayesian zero-inflated binomial geostatistical modeling of the MIS 2008 data (Publications)
(CRDH) with the technical assistance of ICF Macro and the National Malaria Control Programme (NMCP) conducted in 2008/2009 the Senegal Malaria Indicator Survey (SMIS), the first nationally representative household [...] household survey collecting parasitological data and malaria-related indicators. In this paper, we present spatially explicit parasitaemia risk estimates and number of infected children below 5 years. [...] infected children under the age of 5 years is Kolda (13940). The...
Cost-sharing strategies combining targeted public subsidies with private-sector delivery achieve high bednet coverage and reduced malaria transmission... (Publications)
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 [...] but now-obsolete technologies available at the time resulted in low insecticide treatment rates. Malaria transmission remained intense but was substantially reduced: Compared with an exceptionally high
The usefulness of twenty-four molecular markers in predicting treatment outcome with combination therapy of amodiaquine plus... (Publications)
plus sulphadoxine-pyrimethamine (SP) was introduced as first-line treatment against uncomplicated malaria in 2000. METHODS: We assessed in vivo treatment failure rates with AQ+SP in two different areas in
Preventing childhood malaria in Africa by protecting adults from mosquitoes with insecticide-treated nets (Publications)
BACKGROUND: Malaria prevention in Africa merits particular attention as the world strives toward a better life for the poorest. Insecticide-treated nets (ITNs) represent a practical means to prevent malaria in [...] targets for ITN coverage beyond vulnerable groups. METHODS AND FINDINGS: Using field-parameterized malaria transmission models, we show that high (80% use) but exclusively targeted coverage of young children
Three different <em>Plasmodium</em> species show similar patterns of clinical tolerance of malaria infection (Publications)
data on the age dependence of tolerance in other species of human malaria. METHODS: Parasite densities measured in 24,386 presumptive malaria cases at two local health centres in the Wosera area of Papua New [...] to the logarithm of the parasite density for all three malaria species, with little age variation in the relationship for P. vivax or P. malariae. P. falciparum shows more age variation in disease incidence [...] BACKGROUND: In areas where malaria endemicity is high, many people...
Efficacy of sulfadoxine-pyrimethamine in Tanzania after two years as first-line drug for uncomplicated malaria: assessment protocol and implication... (Publications)
BACKGROUND: Systematic surveillance for resistant malaria shows high level of resistance of Plasmodium falciparum to sulfadoxine-pyrimethamine (SP) across eastern and southern parts of Africa. This study
Behavioural determinants of gene flow in malaria vector population: <em>Anopheles gambiae</em> males select large females as mates (Publications)

Fundamental studies of behavioural ecology in malaria vectors such as An. gambiae can have important implications for malaria control and should be prioritised for more extensive investigation [...] BACKGROUND: Plasmodium-refractory mosquitoes are being rapidly developed for malaria control but will only succeed if they can successfully compete for mates when released into the wild. Pre-copulatory [...] structure in wild mosquito populations and mating barriers have foiled...
