Dengue fever is the most common arboviral infection worldwide, but its epidemiology in Africa is still not fully understood. This study reported a case of dengue virus serotype 2 imported from Cote d'Ivoire to Senegal, suggesting a possible spread of strains from the Burkina Faso outbreak to other West African countries. The phylogenetic analysis based on full-length genome sequence revealed a clustering with strains from the Burkina Faso outbreak in 2016 and the ongoing dengue fever outbreak in Cote d'Ivoire.
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 Cote 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 Cote d'Ivoire. This suggests a possible spread of strains from the Burkina Faso outbreak to other West African countries including Cote d'Ivoire and Senegal.
