Behavioural determinants of gene flow in malaria vector population: <em>Anopheles gambiae</em> males select large females as mates (Publications)
transgenic vectors. 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...
A high-resolution geospatial surveillance-response system for malaria elimination in Solomon Islands and Vanuatu (Publications)
provinces of Isabel and Temotu, Solomon Islands and Tafea, Vanuatu. Confirmed malaria cases were reported to provincial malaria offices upon diagnosis and updated into the respective SDSS as part of routine [...] surveillance-response system has been developed within a geographic information system (GIS) to support malaria elimination in the Pacific. This paper examines the application of a GIS-based spatial decision support [...] support system (SDSS) to automatically locate and map the...
A research agenda for malaria eradication: monitoring, evaluation, and surveillance (Publications)
how well public health programs operate over time and achieve their goals. As countries approach malaria elimination, these activities will need to shift from measuring reductions in morbidity and mortality [...] there is a clear need to systematically review the information from past elimination efforts for malaria and other infectious diseases
Evaluating the effectiveness of IPTi on malaria using routine health information from sentinel health centres in southern Tanzania (Publications)
of IPTi on malaria, anaemia, and all-cause attendance in children aged 2-11 months presenting to 11 health centres in southern Tanzania is described. METHODS: Clinical diagnosis of malaria was confirmed [...] BACKGROUND: Intermittent preventive treatment of malaria in infants (IPTi) consists of the administration of a treatment dose of sulphadoxine-pyrimethamine (SP) at the time of routine vaccinations. The
Rapid urban malaria appraisal (RUMA) in sub-Saharan Africa (Publications)
BACKGROUND: The rapid urban malaria appraisal (RUMA) methodology aims to provide a cost-effective tool to conduct rapid assessments of the malaria situation in urban sub-Saharan Africa and to improve the [...] site, providing a good overview of the malaria situation. School and health facility-based surveys provided an overview of local endemicity and the overall malaria burden in different city areas. This helped [...] the understanding of urban malaria epidemiology. METHODS: This work was done...
Intermittent preventive treatment for malaria in Papua New Guinean infants exposed to <em>Plasmodium falciparum</em> and <em>P. vivax</em>: a... (Publications)
(PE) against all episodes of clinical malaria from 3 to 15 mo of age. Analysis was by modified intention to treat. The PE (compared to placebo) against clinical malaria episodes (caused by all species) was [...] No rebound in malaria morbidity was observed for 6 mo following the intervention. CONCLUSIONS: IPTi using a long half-life drug combination is efficacious for the prevention of malaria and anemia in infants [...] Intermittent preventive treatment in infants (IPTi) has been shown in...
Impact of promoting longer-lasting insecticide treatment of bed nets upon malaria transmission in a rural Tanzanian setting with pre-existing high... (Publications)
experienced extremely high malaria transmission in the 1990s. By 2001-03, following high usage rates (75% of all age groups) of untreated bed nets, a 4.2-fold reduction in malaria transmission intensity was [...] Anopheles arabiensis was only 38%. CONCLUSION: Insecticide treatment of nets reduced the intensity of malaria transmission in addition to that achieved by the untreated nets alone. Impacts were most pronounced
Estimation of heterogeneity in malaria transmission by stochastic modelling of apparent deviations from mass action kinetics (Publications)
BACKGROUND: Quantifying heterogeneity in malaria transmission is a prerequisite for accurate predictive mathematical models, but the variance in field measurements of exposure overestimates true micro [...] challenge by infectious vectors. This appears to violate the principle of mass action that is implied by malaria biology. Micro-heterogeneity may be the reason for this anomaly. It is proposed that the level of [...] exposure. METHODS: The relationship between the entomological inoculation...
Community-based surveillance of malaria vector larval habitats: a baseline study in urban Dar es Salaam, Tanzania (Publications)
minimal training and supervision in the first weeks of an operational urban malaria control program. METHODS: The Urban Malaria Control Programme of Dar es Salaam recruited and provided preliminary training [...] the population of Africa rapidly urbanizes it may be possible to protect large populations from malaria by controlling aquatic stages of mosquitoes. Here we present a baseline evaluation of the ability [...] CORPs at the start of the Dar es Salaam UMCP were insufficient to enable...
A research agenda for malaria eradication: vector control (Publications)
variety of malaria transmission environments present in the world today. In each setting, improved control for reduction of morbidity is a necessary first step towards the long-range goal of malaria eradication
