RESUMEN
Lassa fever has not been reported in Côte d'Ivoire. We performed a retrospective analysis of human serum samples collected in Côte d'Ivoire in the dry seasons (January-April) during 2015-2018. We identified a fatal human case of Lassa fever in the Bangolo District of western Côte d'Ivoire during 2015.

Dengue fever is the most common arboviral infection worldwide. Its epidemiology in Africa is not yet fully understood due to the lack of awareness, the presence of other dengue-like febrile diseases, and insufficient laboratory capabilities. This paper reports on the import of dengue virus serotype 2 case from Côte d'Ivoire to Senegal in West Africa. Phylogenetic analysis based on full-length genome sequence revealed that the isolate clustered with strains of cosmopolitan genotypes from the Burkina Faso outbreak in 2016 and those from the ongoing dengue fever outbreak in Côte d'Ivoire. This suggests a possible spread of strains from the Burkina Faso outbreak to other West African countries including Côte d'Ivoire and Senegal.
