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...
Spatially variable risk factors for malaria in a geographically heterogeneous landscape, western Kenya: an explorative study (Publications)
factors for malaria can give insight into which human and environmental characteristics play important roles in sustaining malaria transmission. METHODS: On Rusinga Island, western Kenya, malaria infection [...] negatively associated with malaria prevalence. DISCUSSION: Identification of risk factors for malaria that vary geographically can provide insight into the local epidemiology of malaria. Examining spatially [...] Combining the data from both surveys, overall malaria prevalence was 24 %....
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...
Evaluation of malaria diagnoses using a handheld light microscope in a community-based setting in rural Côte d'Ivoire (Publications)
Portable microscopy may facilitate quality diagnostic care in resource-constrained settings. We compared a handheld light microscope (Newton Nm1) with a mobile phone attachment to conventional light m
Mapping intra-urban malaria risk using high resolution satellite imagery: a case study of Dar es Salaam (Publications)
of malaria in rapidly growing African urban settlements. The complex and heterogeneous nature of urban malaria requires a better understanding of the spatial and temporal patterns of urban malaria risk [...] localized heterogeneity of malaria transmission and develop a high resolution predictive malaria risk map of Dar es Salaam. RESULTS: Results indicate that the risk of malaria infection varied across the [...] settlements by 2030, the burden of malaria among urban populations in Africa...
