A cross-sectional survey was conducted between October and December 2017 in the French Guianese municipality of St Georges de l\u2019Oyapock, located along the Brazilian border. The prevalence of <jats:italic>Plasmodium<\/jats:italic> spp<jats:italic>.<\/jats:italic> was determined using a rapid diagnostic test (RDT) and a polymerase chain reaction (PCR). Demographic, house locations, medical history, and biological data were analyzed. Factors associated with <jats:italic>Plasmodium<\/jats:italic> spp. carriage were analyzed using logistic regression, and the carriage localization was investigated through spatial cluster analysis. Of the 1,501 samples analyzed with PCR, positive results totaled 90 and 10 for <jats:italic>Plasmodium vivax<\/jats:italic> and <jats:italic>Plasmodium falciparum<\/jats:italic>, respectively. The general PCR prevalence was 6.6% [5.3\u20137.9], among which 74% were asymptomatic. Only 13\/1,549 were positive by RDT. In multivariate analysis, participants older than 15 years, living in a remote neighborhood, with a prior history of malaria, anemia, and thrombocytopenia were associated with an increased odds of <jats:italic>Plasmodium<\/jats:italic> spp. carriage. High-risk clusters of <jats:italic>P. vivax<\/jats:italic> carriage were detected in the most remote neighborhoods on the village outskirts and two small foci in the village center. We also detected a hot spot for both <jats:italic>P. vivax<\/jats:italic> and <jats:italic>P. falciparum<\/jats:italic> symptomatic carriers in the northwestern part of the village. The present study confirms a wide-scale presence of asymptomatic <jats:italic>P. falciparum<\/jats:italic> and <jats:italic>P. vivax<\/jats:italic> carriers in this area. Although they were more often located in remote areas, their geographic distribution was spatially heterogeneous and complex.<\/jats:p>","DOI":"10.4269\/ajtmh.19-0378","type":"journal-article","created":{"date-parts":[[2019,11,26]],"date-time":"2019-11-26T07:00:50Z","timestamp":1574751650000},"page":"130-141","source":"Crossref","is-referenced-by-count":28,"title":["Prevalence
