The whole country recorded nearly 100,000 cases of dengue fever.

Statistics from the Ministry of Health show that since the beginning of the year, the country has recorded 99,639 cases and 27 deaths due to dengue fever. Compared to the same period in 2022 (240,419/121), the number of cases decreased by 58% and deaths decreased by 94 cases.

In the capital, according to the Hanoi Center for Disease Control, last week (October 6-13), the city recorded 2,601 cases of dengue fever in 30 districts, towns and cities. Ha Dong District is the leading locality in the number of cases with 250 cases, followed by Phu Xuyen District: 200 cases, Thanh Oai District: 171 cases, Thanh Tri District: 163 cases.

The remaining districts: Cau Giay, Chuong My, Hoang Mai, Thanh Xuan, Bac Tu Liem recorded from 120-124 cases. Last week, 136 dengue fever outbreaks were recorded in 23 districts, towns and cities. This is also the week with the most outbreaks since the beginning of 2023.

Statistics in the past 3 weeks (from the end of September 2023 until now), the number of dengue fever cases in Hanoi has increased sharply, fluctuating between 2,500-2,600 cases/week (1.5 times higher than the first week of September 2023).

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 occurs year-round, often increasing during the rainy season. The disease occurs in both children and adults. The characteristics of dengue fever are fever, bleeding and plasma leakage, which can lead to hypovolemic shock, blood clotting disorders, organ failure, and if not diagnosed early and treated promptly, can easily lead to death.

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.

According to experts, the most worrying thing in dengue fever patients is shock, which often occurs in phase 2 and is difficult to monitor. If the patient receives good intervention right from the warning signs, before shock, the recovery will be quick. If it is not detected and progresses to shock, the situation will be extremely bad, and the survival rate will not be high.
