Title An outbreak of a novel lineage of dengue virus 2 in Vietnam in 2022
Journal Journal of Medical Virology
Abstract In 2022, a large dengue outbreak was reported in Vietnam, where dengue was endemic. A total of 1889 acute‐phase serum samples were collected from patients with suspected dengue at Vung Tau General Hospital, the core hospital in Vung Tau Province, southern Vietnam. Among the 1889 samples analyzed for laboratory confirmation of dengue virus (DENV) infection, 339 positive cases were identified, of which 130 were primary infections and 209 were secondary infections. DENV‐2 was the dominant serotype in both primary and secondary infection groups. Phylogenetic analysis based on sequences of the envelope protein‐coding region revealed the emergence of a new DENV‐2 lineage during this outbreak.
