  abstract = {{B}ackground: {D}espite low endemicity, malaria remains a major health problem in urban areas where a high proportion of fevers are presumptively treated using anti-malarial drugs. {L}ow acquired malaria immunity, behaviour of city-dwellers, access to health care and preventive interventions, and heterogenic suitability of urban ecosystems for malaria transmission contribute to the complexity of the malaria epidemiology in urban areas. {M}ethods: {T}he study was designed to identify the determinants of malaria transmission estimated by the prevalence of anti-circumsporozoite ({CSP}) antibodies, the prevalence and density of {P}lasmodium falciparum infection, and the prevalence of malarial disease in areas of {O}uagadougou, {B}urkina-{F}aso. {T}hick blood smears, dried blood spots and clinical status have been collected from 3,354 randomly chosen children aged 6 months to 12 years using two cross-sectional surveys (during the dry and rainy seasons) in eight areas from four ecological strata defined according to building density and land tenure (regular versus irregular). {D}emographic characteristics, socio-economic information, and sanitary and environmental data concerning the children or their households were simultaneously collected. {D}ependent variables were analysed using mixed multivariable models with random effects, taking into account the clustering of participants within compounds and areas. {R}esults: {O}verall prevalences of {CSP}-antibodies and {P}. falciparum infections were 7.7% and 16.6% during the dry season, and 12.4% and 26.1% during the rainy season, respectively, with significant differences according to ecological strata. {M}alaria risk was significantly higher among children who i) lived in households with lower economic or education levels, iii) near the hydrographic network, iv) in sparsely built-up areas, v) in irregularly built areas, vi) who did not use a bed net, vii) were sampled during the rainy season or ii) had traveled outside of {O}uagadougou. {C}onclusion: {M}alaria control should be focused in areas which are irregularly or sparsely built-up or near the hydrographic network. {F}urthermore, urban children would benefit from preventive interventions (e. g. anti-vectorial devices or chemoprophylaxis) aimed at reducing malaria risk during and after travel in rural areas.},
