  abstract = {{B}ackground: {U}rbanization is a main trend in developing countries and leads to health transition. {A}lthough non-communicable diseases are increasing in cities of low-income countries, vector-borne diseases such as malaria, are still present. {I}n the case of malaria, transmission is lower than in rural areas, but is uneven and not well documented. {I}n this study, we wanted to evaluate intra-urban malaria transmission in a {W}est {A}frican country ({B}urkina {F}aso). {M}ethods: {A} cross-sectional study on 847 adults (35 to 59 year-old) and 881 children (6 months to 5 year-old) living in 1045 households of four districts ({D}ogona, {Y}eguere, {T}ounouma and {S}ecteur 25) of {B}obo-{D}ioulasso was performed between {O}ctober and {N}ovember 2013. {T}he districts were selected according to a geographical approach that took into account the city heterogeneity. {M}alaria prevalence was evaluated using thick and thin blood smears. {H}uman exposure to {A}nopheles bites was measured by assessing the level of {I}g{G} against the {A}nopheles g{SG}6-{P}1 salivary peptide. {A}dult mosquitoes were collected using {CDC} traps and indoor insecticide spraying in some houses of the four neighbourhoods. {T}he {A}nopheles species and {P}lasmodium falciparum infection rate were determined using {PCR} assays. {R}esults: {I}n this study, 98.5% of the malaria infections were due to {P}lasmodium falciparum. {M}alaria transmission occurred in the four districts. {M}alaria prevalence was higher in children than in adults (19.2 vs 4.4%), and higher in the central districts than in the peripheral ones ({P} = 0.001). {T}he median {I}g{G} level was more elevated in {P}. falciparuminfected than in non-infected individuals ({P} < 0.001). {A}nopheles arabiensis was the main vector identified (83.2%; 227 of the 273 tested mosquito specimens). {F}ive {P}. falciparum-infected mosquitoes were caught and they were all caught in the central district of {T}ounouma where 28.6% (14/49) of the tested blood-fed mosquito specimens had a human blood meal. {C}onclusions: {T}his study showed that urban malaria transmission occurred in {B}obo-{D}ioulasso, in all the four studied areas, but mainly in central districts. {E}nvironmental determinants primarily explain this situation, which calls for better urban management.},
