  abstract = {{D}espite the large reduction in malaria incidence in the last decade, the last kilometre to elimination is often the hardest, especially in international border areas. {T}his study investigated the impact of mobility on {P}lasmodium spp. carriage in people living in a cross-border area in {A}mazonia with a low malaria transmission rate. {W}e implemented a longitudinal ancillary study in the {F}rench {G}uiana town of {S}t. {G}eorges de l'{O}yapock, which is located on the border with {B}razil. {I}t was based on data from two transversal surveys performed in {O}ctober 2017 and {O}ctober 2018. {D}ata were collected on peri-domestic mobility for food-producing activities, and longer-distance mobility in high-risk areas. {P}articipants were screened for {P}lasmodium spp. carriage using {PCR} tests, and treated if positive. {V}ector density around a participant's home was estimated using a previously published model based on remote sensing and meteorological data. {T}he association between {P}lasmodium spp. carriage and mobility was analysed using a generalized additive mixed model. {A} total of 1,192 inhabitants, aged between 0 and 92 years old, were included. {M}edian age was 18 years in 2017 ({IQR} [8;35]). {P}lasmodium spp. prevalence in the study population was 7% in 2017 (n = 89) and 3% in 2018 (n = 35). {P}lasmodium spp. carriage was independently associated with i) travel to the adjoining {O}iapoque {I}ndigenous {T}erritories in {B}razil ({OR} = 1.76, p = 0.023), ii) the estimated vector density around a participant's home ({H}igh versus {L}ow risk {OR} = 4.11, p<0.001), iii) slash-and-burn farming ({OR} = 1.96, p = 0.013), and iv) age (p = 0.032). {S}pecific surveillance systems and interventions which take into account different types of mobility are needed in cross-border areas to achieve and maintain malaria elimination (e.g., reactive case detection and treatment in the places visited).},
