Discussion

Genetic analysis reveals predominant DENV-2 and multiple introductions in Saudi Arabia, suggesting evolving transmission dynamics.

Phylogeographic analysis identifies at least five distinct introductions of DENV-2 from India, Sri Lanka, and Pakistan.
Serotyping revealed DENV-2 as the dominant serotype, with 20 full genomes sequenced across different serotypes.
Increased mass gatherings and labor migration are driving factors in the evolution of regional dengue transmission.
Strengthening genomic surveillance is critical for improving outbreak response to dengue virus spread.

Bello et al. (2025) studied this question.
