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
Cost implications of improving malaria diagnosis: findings from north-eastern Tanzania (Publications)
diagnosis of malaria was estimated by comparing the proportion of outpatient attendees of all ages clinically diagnosed as malaria to the proportion of attendees having a positive malaria rapid diagnostic [...] diagnosis of malaria contributes to improper treatment, wastage of drugs and resistance to the few available drugs. This paper attempts to estimate the rates of over diagnosis of malaria among children
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...
Allomonal effect of breath contributes to differential attractiveness of humans to the African malaria vector Anopheles gambiae (Publications)
contributes to between-person differences in relative attractiveness to the highly anthropophilic malaria vector Anopheles gambiae sensu stricto remains unknown and was the focus of the present study. METHODS: [...] contributor to between-person differences in the relative attractiveness of humans to this important malaria vector
Interpreting malaria age-prevalence and incidence curves: a simulation study of the effects of different types of heterogeneity (Publications)
Individuals in a malaria endemic community differ from one another. Many of these differences, such as heterogeneities in transmission or treatment-seeking behaviour, affect malaria epidemiology. The [...] heterogeneity were incorporated into a comprehensive individual-based model of Plasmodium falciparum malaria epidemiology. The different types of heterogeneity were systematically simulated individually, and
Artemisinin-based combination therapy does not measurably reduce human infectiousness to vectors in a setting of intense malaria transmission (Publications)
n therapy (ACT) for treating malaria has activity against immature gametocytes. In theory, this property may complement the effect of terminating otherwise lengthy malaria infections and reducing the parasite [...] are common and cured patients are rapidly and repeatedly re-infected. METHODS: From 2001 to 2004, malaria vector densities were monitored using light traps in three Tanzanian districts. Mosquitoes were dissected [...] determined by ELISA. Sulphadoxinepyrimethamine (SP) monotherapy was...
Microbial larvicide application by a large-scale, community-based program reduces malaria infection prevalence in urban Dar es Salaam, Tanzania (Publications)
BACKGROUND: Malaria control in Africa is most tractable in urban settlements yet most research has focused on rural settings. Elimination of malaria transmission from urban areas may require larval control [...] managed, delivery systems in urban Dar es Salaam, Tanzania. Continuous, randomized cluster sampling of malaria infection prevalence and non-random programmatic surveillance of entomological inoculation rate (EIR) [...] = 0.001) when 45% (9/20) of directly observed transmission events...
Obstacles to prompt and effective malaria treatment lead to low community-coverage in two rural districts of Tanzania (Publications)
BACKGROUND: Malaria is still a leading child killer in sub-Saharan Africa. Yet, access to prompt and effective malaria treatment, a mainstay of any malaria control strategy, is sub-optimal in many settings [...] location of treatment sources. RESULTS: After intensive health education, the biomedical concept of malaria has largely been adopted by the community. 87.5% (78.2-93.8) of the fever cases in children and 80
