Dengue fever is a viral infectious disease and transmitted by mosquitoes. Currently, we do not have specific treatment and vaccine for Dengue. Dengue prevention relies mainly on the surveillance, vector control and encouragement of communities to undertake prevention activities by themselves. Dengue sentinel surveillance activities in Northern of Vietnam had been launched in 3 provinces: Hai Phong, Nam Dinh and Thai Binh. In 2014, the Dengue sentinel surveillance system reported 201 Dengue cases without deaths. Dengue cases occurred during all months of the year, with their peaks seen in August, September and October. Thai Binh province reported the presence of Ae. albopictus mosquito only in its sentinel sites; its Bretaux index (BI) and mosquito density index (DI) were under risk cut-off value except for October and November. Hai Phong and Nam Dinh provinces reported both Ae. albopictus and Ae. aegypti mosquitoes in their sentinel sites. BI and DI of Ae. albopictus in Hai Phong were higher than risk cut-off value, and Ae. aegypti indices were low in both provinces.
