While the number of cases are higher than previous years, a definite downward trend is being seen. For example, in the two most recent weeks recorded, Vietnam saw a nearly 20 percent reduction of cases week-to-week.

The Central-coastal and the Southern regions of the country were most affected in 2017. In Ha Noi, as of 15 October 2017, there were approximately 33,600 dengue cases recorded including seven deaths.

Dengue is a viral infection transmitted by the bite of an infected mosquito. There are four closely related but antigenically different serotypes of the virus that can cause dengue (DEN1, DEN 2, DEN 3, DEN 4).
