Spatial risk prediction and mapping of Schistosoma mansoni infections among schoolchildren living in western Côte d'Ivoire
Raso, Giovanna
"The objectives of this study were (1) to examine risk factors for Schistosoma mansoni infection among schoolchildren living in western Côte d'Ivoire, and (2) to carry forward spatial risk prediction and mapping at non-sampled locations [...]. Results showed that age, sex, the richest wealth quintile, elevation and rainfall explained the geographical variation of the school prevalences of S. mansoni infection. The goodness of fit of different spatial models revealed that age, sex and socio-economic status had a stronger influence on infection prevalence than environmental covariates. The generated risk map can be used by decision-makers for the design and implementation of schistosomiasis control in this setting. If successfully validated elsewhere, this approach can guide control programmes quite generally." Parasitology 2005, Vol. 131, Issue 1, pp. 97-108 Available from: Cambridge Univeristy Press
Urban agricultural land use and characterization of mosquito larval habitats in a medium-sized town of Côte d’Ivoire
Matthys, Barbara
"Urban agriculture is common across Africa and contributes to the livelihoods of urban dwellers. Some crop systems create suitable mosquito breeding sites and thus might affect malaria transmission. The purpose of this study was to identify, map, and characterize potential mosquito breeding sites in agricultural land use zones in a medium-sized town of western Côte d’Ivoire and to assess risk factors for productive Anopheles breeding sites. Two surveys were carried out; one toward the end of the rainy season and the second one during the dry season. [...] The highest Anopheles larval productivity was observed in rice paddies, agricultural trenches between vegetable patches, and irrigation wells. An indirect link could be established between the occurrence of productive Anopheles breeding sites and agricultural land use through specific man-made habitats, in particular agricultural trenches, irrigation wells, and rice paddies. Our findings have important bearings for the epidemiology and control of urban malaria in sub-Saharan Africa."

Multiple parasite infections and their relationship to self-reported morbidity in a community of rural Côte d'Ivoire
Raso, Giovanna
"Concomitant parasitic infections are common in the developing world, yet most studies focus on a single parasite in a narrow age group. We investigated the extent of polyparasitism and parasite associations, and related these findings to self-reported morbidity. [...] Our data confirm that polyparasitism is very common in rural Côte d'Ivoire and that people have clear perceptions about the morbidity caused by some of these parasitic infections. Our findings can be used for the design and implementation of sound intervention strategies to mitigate morbidity and co-morbidity."

Le réseau social des maraîchers à Abidjan agit sur la perception des préoccupations et des risques sanitaires liés à l’eau
Matthys, Barbara
"L'objectif de la présente étude conduite dans des zones de production maraîchère d'Abidjan, Côte d'Ivoire, était d'analyser les problèmes principaux des cultivateurs; leur perceptions des maladies et des risques sanitaires et la corrélation entre les risques sanitaires et le statut socio-économique des ménages ainsi que la cohésion sociale dans les communautés maraîchères. Les problèmes principaux sont l'insécurité foncière et de difficultés de commercialisation. Les préoccupations sanitaires sont la fatigue et l'insalubrité. En l'absence d'une éducation sanitaire fondée et des interventions localement adaptées, les cultivateurs n'accordent pas une attention particulière à la prévention des risques sanitaires. Le support technique, en concordance avec l'éducation et la communication de la prévention des risques sanitaires, promettent une augmentation de la productivité et une amélioration des moyens de subsistance des ménages cultivateurs à Abidjan."

Urban farming and malaria risk factors in a medium-sized town of Côte d’Ivoire
Matthys, Barbara
"Urbanization occurs at a rapid pace across Africa and Asia and affects people’s health and well-being. A typical feature in urban settings of Africa is the maintenance of traditional livelihoods, including agriculture. The purpose of this study was to investigate malaria risk factors in urban farming communities in a medium-sized town in Côte d’Ivoire. Two cross-sectional surveys were carried out among 112 households from six agricultural zones. [...] Our findings indicate that specific crop systems and specific agricultural practices may increase the risk of malaria in urban settings of tropical Africa."

Disparities in parasitic infections, perceived ill health and access to health care among poorer and less poor schoolchildren of rural Côte d'Ivoire
Raso, Giovanna
"Differences in the state of health between rural and urban populations living in Africa have been described, yet only few studies analysed inequities within poor rural communities. We investigated disparities in parasitic infections, perceived ill health and access to formal health services among more than 4000 schoolchildren from 57 primary schools in a rural area of western Côte d'Ivoire, as measured by their socioeconomic status. [...] Our study provides evidence for inequities among schoolchildren's parasitic infection status, perceived ill health and access to health care in a large rural part of Côte d'Ivoire. These findings call for more equity-balanced parasitic disease control interventions, which in turn might be an important strategy for poverty alleviation."
