The deceased case was a 78-year-old female patient (in Dan Phuong district) with dengue fever on the background of many chronic diseases such as: High blood pressure, type 2 diabetes and a stroke.

From the beginning of 2023 to now, Hanoi has recorded 23,314 cases of dengue fever, including 4 deaths (the number of cases increased 3 times and the number of deaths decreased by 5 cases compared to the same period in 2022).

Hanoi CDC believes that the dengue fever epidemic may continue to increase in the coming weeks. Therefore, dengue fever surveillance and prevention work continues to be strengthened in outbreak areas in the following districts: Phu Xuyen, Dong Anh, Thanh Oai, Nam Tu Liem, Tay Ho, Hai Ba Trung, Chuong My.

According to the World Health Organization, in 2023 and 2024, climate change and El Nino may promote mosquito breeding, increasing the transmission of dengue fever and other mosquito-borne diseases, according to the Department of Preventive Medicine (Ministry of Health).

In the coming time, due to the peak of the rainy season, the number of cases will continue to have complicated developments and tend to increase if drastic measures are not taken to prevent the epidemic, especially activities to kill mosquitoes, larvae, and pupae in localities.

Dengue fever is an infectious disease caused by the dengue virus. There are four serotypes of the dengue virus: DEN-1, DEN-2, DEN-3, and DEN-4. The virus is transmitted from infected people to healthy people through mosquito bites. The Aedes aegypti mosquito is the main vector.

Dengue fever has diverse clinical manifestations, progressing rapidly from mild to severe. The disease usually starts suddenly and progresses through three stages: febrile stage, dangerous stage and recovery stage. Early detection of the disease and understanding the clinical problems in each stage of the disease helps in early diagnosis, correct and timely treatment, in order to save the patient's life.
