Genetic analyses reveal locally transmitted dengue virus serotype 3 in Angola, suggesting potential American origins.
We detected dengue virus serotype 3 in 11.8% (16/136) of febrile patients in Luanda Province, Angola, during April and July 2024. Our genetic analyses reveal that dengue virus serotype 3 lineage III_B.3.2 probably was imported from the Americas into Angola in late 2022 and then spread through local transmission.
