Abstract
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.

Summary
There 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. Plasmodium falciparum malaria remains a key global driver of mortality and morbidity with people in sub-Saharan Africa affected most [1,2]. According to the world malaria report, the entire population of Côte d’Ivoire is at risk of malaria [2] and Anopheles gambiae is the primary vector species [4,5]. Key tools and strategies to fight against malaria include, among others, early diagnosis and treatment with artemisinin-based combination therapy (ACT) and distribution of long-lasting insecticidal nets (LLINs) to populations at risk. Eight million LLINs were distributed in 2011 and further scaling-up of free LLIN distribution (12 million) to the entire population was planned for the last quarter of 2014
