Rapid spread of the emerging cosmopolitan genotype of dengue virus serotype 2, and expansion of dengue virus serotype 1 genotype V in Peru.

ABSTRACT:

Background

Motivation for the study. This study aimed to analyze the prevalence and distribution of the V genotypes of dengue virus type 1 (DENV-1) and the cosmopolitan genotype DENV-2 in Peru, in order to understand their expansion in different regions; since these viruses can cause important outbreaks in the country. Main findings. A rapid spread and wide distribution of the cosmopolitan DENV-2 genotype was reported in Peru in 2022, following its initial introduction in 2019. DENV-1 genotype V, present in Peru since the 1990s, has now expanded to new Peruvian regions, after previously being restricted to rural and jungle areas in the north of the country. Implications. The results highlight the urgent need to strengthen epidemiological and genomic surveillance systems to monitor
