  abstract = {{L}aboratory-confirmed dengue virus ({DENV}) infections in {A}frica are rarely reported. {I}n this study, we report 18 {DENV} serotype 1 ({DENV}-1) infections, diagnosed by the {F}rench {N}ational {R}eference {C}enter for {A}rboviruses, in patients who had histories of recent travel in {A}frica. {O}ur analyses revealed two cases, one from {N}iger in 2018 and one from the {R}epublic of the {C}ongo in 2016, where dengue fever had not been previously reported, and one case from {M}auritania in 2015, where {DENV}-1 had not been previously reported. {T}hese cases support the reported spread of {DENV} outside its well-established tropical and subtropical environment toward the arid deserts of the {S}ahel. {P}hylogenetic analyses suggest that a single monophyletic {DENV}-1 lineage is currently in circulation in {W}est {A}frica, having spread from {E}ast {A}frica after its original importation from {A}sia. {O}ur study provides an improved understanding of {DENV} dynamics in {A}frica and underlines the importance of surveillance of travel-acquired infections.},
