Modelling heterogeneity in malaria transmission using large sparse spatio-temporal entomological data (Publications)
Background: Malaria transmission is measured using entomological inoculation rate (EIR), number of infective mosquito bites/person/unit time. Understanding heterogeneity of malaria transmission has been [...] database compiled by the Malaria Transmission Intensity and Mortality Burden across Africa (MTIMBA) project (2001-2004) at several sites is the most suitable dataset for studying malaria transmission-mortality [...] a rigorous approach for analysing large and highly variable entomological...
A cluster-randomized controlled trial to assess the effectiveness of using 15% DEET topical repellent with long-lasting insecticidal nets (LLINs)... (Publications)
al nets (LLINs) have limited effect on malaria transmitted outside of sleeping hours. Topical repellents have demonstrated reduction in the incidence of malaria transmitted in the early evening. This study [...] likely a result of lack of statistical power, poor capture of malaria events or bias caused by imbalance in the SES of the two groups. Low malaria transmission during the study period could have masked the [...] study assessed whether 15% DEET topical repellent used in combination with...
Effect of deworming on school-aged children's physical fitness, cognition and clinical parameters in a malaria-helminth co-endemic area of Côte... (Publications)
BACKGROUND: Malaria and helminth infections are thought to negatively affect children's nutritional status and to impair their physical and cognitive development. Yet, the current evidence-base is weak [...] helminthiasis and schistosomiasis on children's physical fitness, cognition and clinical parameters in a malaria-helminth co-endemic setting of Cote d'Ivoire. METHODS: We designed an intervention study with a 5-month [...] speculate that potential beneficial effects of deworming are likely...
Community response to intermittent preventive treatment of malaria in infants (IPTi) in Papua New Guinea (Publications)
Africa this article aims to investigate the acceptability of intermittent preventive treatment of malaria in infants (IPTi) in Papua New Guinea (PNG). METHODS: A questionnaire was administered to mothers [...] is little evidence that IPTi has negative impacts on attitudes to EPI, EPI adherence or existing malaria prevention practices. CONCLUSION: The degree of similarity between findings from the acceptability [...] health cultures, appears to be accepted easily and has little impact on...
Rise in malaria incidence rates in South Africa: a small-area spatial analysis of variation in time trends (Publications)
analysis were that: 1) the spatial distribution of the rise in malaria incidence is uneven and strongly suggests a geographic expansion of high-malaria-risk areas; 2) there is evidence of a stabilization of incidence [...] Bayesian statistical models, the authors investigated spatial and temporal variations in small-area malaria incidence rates for the period mid-1986 to mid-1999 for two districts in northern KwaZulu Natal,
Eradication of<em> Anopheles gambiae</em> from Brazil: lessons for malaria control in Africa? (Publications)
Current malaria-control strategies emphasise domestic protection against adult mosquitoes with insecticides, and improved access to medical services. Malaria prevention by killing adult mosquitoes is generally [...] suppressed malaria for over 20 years around a Zambian copper mine. These affordable approaches were neglected after the advent of dichlorodiphenyl trichloroethane (DDT) and global malaria-control policy [...] be re-prioritised for research, development, and implementation as an...
Malaria transmission dynamics in central Côte d'Ivoire: the influence of changing patterns of irrigated rice agriculture (Publications)
The dynamics of malaria transmission was studied comparatively in the villages of Zatta and Tiemelekro, central Cote d'Ivoire, from February 2002 to August 2003. Prominent agroecosystems in these villages [...] Tiemelekro, respectively. Anopheles gambiae Giles s.l. was the predominant mosquito and the key malaria vector throughout, followed by An. funestus Giles. Anthropophily among adult female Anopheles exceeded [...] to a farmers' conflict over land, might be the underlying cause for the...
