First Full-Length Genome Sequence of Dengue Virus Serotype 2 Circulating in Vietnam in 2017.

Introduction: Dengue hemorrhagic fever is caused by four serotypes of dengue viruses transmitted by mosquitoes. In Vietnam, dengue outbreaks occur every year, and all four serotypes have been found circulating with the dominant one varying over time. However, in 2017 an unusual dengue fever outbreak occurred in the North of Vietnam, predominantly caused by DENV1 (92%) and DENV2 (7.

Whole genome sequencing and genetic variations in several dengue virus type 1 strains from unusual dengue epidemic of 2017 in Vietnam.

Background: Dengue hemorrhagic fever is an acute viral infection transmitted by mosquitoes. In the 2017, a dengue epidemic occurred in Hanoi in a short time interval and many cases were serious with associated mortality. This was the largest and unusual dengue fever outbreak in the North of Vietnam over the past 20 years.
