This article reveals a major advancement in dengue research in Benin, with the first detection of serotypes 1 (DENV-1) and 3 (DENV-3) in humans. Out of 464 patients presenting with suspected symptoms, four tested positive, and their samples were analyzed using genomic sequencing. With the support of AFROSCREEN, researchers identified specific mutations in these viruses and were also able to classify them accurately. The sequences of serotype 1 show similarities to recent sequences found in Burkina Faso and Nigeria, while the sequences of serotype 3 are closely related to those detected in Burkina Faso.

This surveillance is crucial for deepening our understanding of dengue epidemiology. Tracking the different serotypes allows for a better grasp of the virus’s transmission dynamics, which is essential for anticipating outbreaks and adapting public health strategies. By strengthening these efforts, we can ensure an effective response to this growing health threat.
