Impact of artemisinin-based combination therapy and insecticide-treated nets on malaria burden in Zanzibar (Publications)
The Roll Back Malaria strategy recommends a combination of interventions for malaria control. Zanzibar implemented artemisinin-based combination therapy (ACT) for uncomplicated malaria in late 2003 and [...] all malaria patients, while LLINs are distributed free to children under age 5 y ("under five") and pregnant women. We investigated temporal trends in Plasmodium falciparum prevalence and malaria-related [...] y) mortality decreased by 52%, 33%, and 71%, respectively. Similarly, malaria-rel...
Strategic roles for behaviour change communication in a changing malaria landscape (Publications)
quality strategic behaviour change communication (BCC) can improve malaria prevention and treatment behaviours. As progress is made towards malaria elimination, BCC becomes an even more important tool. BCC can [...] infections and their compliance with treatment, 3) to inform communities of the optimal timing of malaria control interventions, and 4) to explain changing diagnostic concerns (e.g. increasing false negatives [...] this commentary is to highlight the benefits and value for money that...
Spatially aggregated clusters and scattered smaller loci of elevated malaria vector density and human infection prevalence in urban Dar es Salaam,... (Publications)
density and eight of malaria infection prevalence were detected over both phases. Only a third of vectors were collected in hotspots in phase 1 (30 %) and phase 2 (33 %). Malaria prevalence hotspots accounted [...] BACKGROUND: Malaria transmission, primarily mediated by Anopheles gambiae, persists in Dar es Salaam (DSM) despite high coverage with bed nets, mosquito-proofed housing and larviciding. New or improved [...] improved vector control strategies are required to eliminate malaria from...
Mapping hotspots of malaria transmission from pre-existing hydrology, geology and geomorphology data in the pre-elimination context of Zanzibar,... (Publications)
BackgroundLarval source management strategies can play an important role in malaria elimination programmes, especially for tackling outdoor biting species and for eliminating parasite and vector populations [...] larval source management requires tools for identifying geographic foci of vector proliferation and malaria transmission where these efforts may be concentrated. Previous studies have relied on surface topographic [...] examine the relationship between dry and wet season spatial...
Estimating malaria burden in Nigeria: a geostatistical modelling approach (Publications)
This study has produced a map of malaria prevalence in Nigeria based on available data from the Mapping Malaria Risk in Africa (MARA) database, including all malaria prevalence surveys in Nigeria that [...] correlating with malaria presence were land surface temperature for day and rainfall. It was also found that malaria prevalence increased with distance to water bodies up to 4 km. The malaria risk map estimated [...] low malaria prevalence were found to be scattered around the country with...
Changes in malaria burden and transmission in sentinel sites after the roll-out of long-lasting insecticidal nets in Papua New Guinea (Publications)
exhibits a complex malaria epidemiology due to diversity in malaria parasites, mosquito vectors, human hosts, and their natural environment. Heterogeneities in transmission and burden of malaria at various scales [...] scales are likely to affect the success of malaria control interventions, and vice-versa. This manuscript assesses changes in malaria prevalence, incidence and transmission in sentinel sites following the [...] Diagnosis of malaria infection in humans was done by rapid diagnostic...
A malaria risk map of Kinshasa, Democratic Republic of Congo (Publications)
This study presents the first malaria risk map of Kinshasa, a mega city of roughly 10 million inhabitants and located in a highly endemic malaria zone. Prevalence of malaria, anaemia and reported fever was [...] prevalence for malaria and anaemia was 6.4 % (5.6-7.4) and 65.1 % (63.7-66.6) in 2009, and 17.0 % (15.7-18.3) and 64.2 % (62.6-65.9) in 2011. In two HZs sampled in both surveys, malaria prevalence was [...] BACKGROUND: In Kinshasa, malaria remains a major public health problem but its...
Estimating malaria transmission intensity from <em>Plasmodium falciparum</em> serological data using antibody density models (Publications)
BACKGROUND: Serological data are increasingly being used to monitor malaria transmission intensity and have been demonstrated to be particularly useful in areas of low transmission where traditional measures
The effects of an oil and wheat flour fortification program on pre-school children and women of reproductive age living in Côte d'Ivoire, a... (Publications)
Anemia and micronutrient deficiencies are widespread in sub-Saharan Africa, but the impact of food fortification is still debated. The objective of this study was to estimate the iron and vitamin A st
