Epidemiology and Genotype Dynamics of Dengue in Hospitalized Patients in Northern Vietnam Between 2020 and 2022.

ABSTRACT:

Background

Arboviruses, including Dengue (DENV), Zika, and chikungunya, cause recurrent outbreaks of varying intensity in tropical countries. This study aimed to investigate other arboviruses, including Zika and chikungunya, in patients clinically suspected of Dengue and to characterize the circulating Dengue serotypes and genotypes in Northern Vietnam from 2020 to 2022. To date, information on this topic in the region has been limited.

Methods

Multiplex real-time polymerase chain reaction (PCR) was used to detect Dengue, Zika, and chikungunya RNA, and DENV serotypes were identified via real-time reverse transcriptase PCR from 426 clinically Dengue suspected patients. Patients were screened for NS1 antigen and anti-DENV immunoglobulin (Ig) G/IgM antibodies. Phylogenetic anal
