BackgroundThere is limited knowledge on the malaria burden of school-aged children in Côte d’Ivoire. The aim of this study was to assess Plasmodium falciparum infection, malaria-related morbidity, use of preventive measures and treatment against malaria, and physical access to health structures among school-aged children across Côte d’Ivoire.MethodsA national, cross-sectional study was designed, consisting of clinical and parasitological examinations and interviews with schoolchildren. More than 5,000 children from 93 schools in Côte d’Ivoire were interviewed to determine household socioeconomic status, self-reported morbidity and means of malaria prevention and treatment. Finger-prick blood samples were collected and Plasmodium infection and parasitaemia determined using Giemsa-stained blood films and a rapid diagnostic test (RDT). Haemoglobin levels and body temperature were measured. Children were classified into wealth quintiles using household assets and principal components analysis (PCA). The concentration index was employed to determine significant trends of health variables according to wealth quintiles. Logistic and binomial negative regression analyses were done to investigate for associations between P. falciparum prevalence and parasitaemia and any health-related variable.ResultsThe prevalence of P. falciparum was 73.9% according to combined microscopy and RDT results with a geometric mean of parasitaemia among infected children of 499 parasites/μl of blood. Infection with P. falciparum was significantly associated with sex, socioeconomic status and study setting, while parasitaemia was associated with age. The rate of bed net use was low compared to the rate of bed net ownership. Preventive measures (bed net ownership, insecticide spray and the reported use of malaria treatment) were more frequently mentioned by children from wealthier households who were at lower risk of P. falciparum infection. Self-reported morbidity (headache) and clinical morbidity (anaemia) were more often reported by children from less wealthy households.ConclusionSeven out of ten school-aged children in Côte d’Ivoire are infected with P. falciparum and malaria-related morbidity is considerable. Furthermore, this study points out that bed net usage is quite low and there are important inequalities in preventive measures and treatment. These results can guide equity-oriented malaria control strategies in Côte d’Ivoire.Electronic supplementary materialThe online version of this article (doi:10.1186/1475-2875-14-7) contains supplementary material, which is available to authorized users.

Background: Bushmeat represents an important animal protein source for populations in rural areas of Côte d'Ivoire; consequently, the exploitation of the bushmeat reserves has contributed to food security in these areas for long time. However, emergence of Ebola virus disease (EVD) in West Africa in 2014 has led to a ban and stigmatization of this essential food source in rural zones. The present study analyses the influence of the decision to ban bushmeat consumption due to EVD on the patterns of consumption of proteins sources and food security. It aims to characterize the different protein sources consumed in rural areas in the Toumodi region before and after the EVD outbreak in order to identify alternatives to bushmeat. Results:The results demonstrated that fish remains the principal animal protein source (92.1% of households) even outside the EVD crisis. Among protein sources, only bushmeat and fish consumptions have been modified with the Ebola threat. The proportion of households that regularly consume bushmeat decreased to 19.8%, however, this reduction in consumption has been driving by sensitization and repression. Fish consumption frequency increased from 4 to 7 times per week in the EVD crisis period. Picking up in the bush is a main mode of supply of some protein sources such as snail or shellfish but their seasonal character limits their use in the households. Vegetable protein sources seem to play a minor role in the diet of the households assessed, whereas edible mushrooms are consumed frequently to complement or substitute animal protein sources. Conclusion:The ban on bushmeat has led to a reduction in its consumption while fish and edible mushrooms seem to have filled related protein deficits in the households assessed. However, constraints in availability and utilization of these alternative sources build an inconsistent basis to fulfil the nutritional needs. To counteract potentially arising protein deficiencies among the population, the development and implementation of fish farming and livestock at short cycle are suggested in order to improve access to protein sources other than bushmeat.

RESUME L'objectif de ce travail est d'évaluer la digestibilité du fourrage vert, C. pubescens, et son impact sur la croissance ainsi que la santé digestive du lapin de chaire en élevage artisanal. Deux lots de 15 lapins sevrés à 35 jours, élevés en cage individuelle et nourris à l'aide de deux aliments complémentés ou non avec du C. pubescens ont été constitués. La digestibilité des nutriments à 50 jours d'âge de la ration contenant le fourrage

BackgroundIn Côte d’Ivoire, malaria remains a major public health issue, and thus a priority to be tackled. The aim of this study was to identify spatially explicit indicators of Plasmodium falciparum infection among school-aged children and to undertake a model-based spatial prediction of P. falciparum infection risk using environmental predictors.MethodsA cross-sectional survey was conducted, including parasitological examinations and interviews with more than 5,000 children from 93 schools across Côte d’Ivoire. A finger-prick blood sample was obtained from each child to determine Plasmodium species-specific infection and parasitaemia using Giemsa-stained thick and thin blood films. Household socioeconomic status was assessed through asset ownership and household characteristics. Children were interviewed for preventive measures against malaria. Environmental data were gathered from satellite images and digitized maps. A Bayesian geostatistical stochastic search variable selection procedure was employed to identify factors related to P. falciparum infection risk. Bayesian geostatistical logistic regression models were used to map the spatial distribution of P. falciparum infection and to predict the infection prevalence at non-sampled locations via Bayesian kriging.ResultsComplete data sets were available from 5,322 children aged 5–16 years across Côte d’Ivoire. P. falciparum was the predominant species (94.5 %). The Bayesian geostatistical variable selection procedure identified land cover and socioeconomic status as important predictors for infection risk with P. falciparum. Model-based prediction identified high P. falciparum infection risk in the north, central-east, south-east, west and south-west of Côte d’Ivoire. Low-risk areas were found in the south-eastern area close to Abidjan and the south-central and west-central part of the country.ConclusionsThe P. falciparum infection risk and related uncertainty estimates for school-aged children in Côte d’Ivoire represent the most up-to-date malaria risk maps. These tools can be used for spatial targeting of malaria control interventions.Electronic supplementary materialThe online version of this article (doi:10.1186/s13071-016-1775-z) contains supplementary material, which is available to authorized users.
