The number of dengue fever cases in Hanoi tends to increase.

According to the Hanoi Center for Disease Control (CDC), last week (from October 17 to October 24), the entire city recorded 392 cases of dengue fever in 104 wards and communes, an increase of 38 cases compared to the previous week.

During the week, Hanoi CDC recorded 12 dengue fever outbreaks in Bach Mai, Thanh Oai (2); Co Do, Ha Dong, Kim Lien, Phu Luong, Phuong Duc, Tam Hung, Thuong Phuc, Yen Nghia, a decrease of 6 outbreaks compared to the previous week. In 2025, 192 outbreaks were recorded, with 27 currently active.

During the week, Hanoi CDC supervised the investigation and handling of 4 high-risk areas and dengue fever outbreaks, including: Hong Son, Tien Thang, Bo De, and Dan Hoa communes.

Dengue fever in Hanoi is on the rise.

At the same time, Hanoi CDC coordinated with the Department of Medical Examination and Treatment to monitor environmental sanitation and epidemic prevention at the National Assembly Building to serve the 10th Session of the 15th National Assembly; check environmental sanitation and collect water samples at the National Exhibition Center to serve the 2025 Autumn Fair; check environmental sanitation and collect water samples at the National Convention Center and JW Marriott Hanoi Hotel to serve the Opening Ceremony of the United Nations Convention against Cybercrime.

Next week, ward and commune health stations will continue to effectively monitor and detect patients at decentralized health facilities, on software systems and in the community, to promptly investigate and handle cases and outbreaks, and prevent the disease from spreading.

Regularly monitor the indicators of larvae and mosquitoes transmitting dengue fever in areas with cases, old outbreaks and high-risk areas, thereby deploying timely response activities.

Actively deploy Chikungunya disease prevention and control combined with dengue fever prevention through mosquito larvae eradication campaigns and spraying chemicals to kill adult mosquitoes in high-risk areas and epidemic hotspots.

Hanoi CDC coordinated with units to monitor dengue fever outbreak areas in Hoa Xa, Thuong Tin, Tay Mo, Quang Oai and strengthen medical quarantine at Noi Bai International Airport, in order to promptly detect suspected/infected cases and apply appropriate and timely epidemic prevention and control measures.

Last week, the Hanoi CDC recorded 187 cases of hand, foot and mouth disease in 74 wards and communes, including 14 cases in Co Do, 9 cases in Quang Oai, Vat Lai, 8 cases in Tay Mo, and 7 cases in Dai Mo; an increase of 56 cases compared to last week. There were 17 cases of measles in 12 wards and communes, an increase of 10 cases compared to last week. There was 1 case of whooping cough in Thanh Xuan and 1 case of adult tetanus in Yen Hoa. No other epidemics were recorded this week.

Severe warning signs to watch out for include extreme fatigue, lethargy, restlessness, abdominal pain, persistent vomiting, nosebleeds, bleeding gums, vomiting blood, or passing black stools.

When these symptoms appear, the patient should be taken to a medical facility as soon as possible. It is important to note that you should never administer IV fluids at home on your own, as this can make the disease worse and more difficult to control.

In the context of the epidemic at its peak, the most effective preventive measure is still to proactively avoid mosquito bites, destroy larvae, maintain environmental hygiene and remove objects containing stagnant water.

People should sleep under mosquito nets, wear long-sleeved clothes, and use mosquito repellent creams or sprays. In addition, for those who are eligible and in risk groups, vaccination against dengue fever is an effective way to reduce the risk of disease and serious complications.

There are currently two vaccines that have been prequalified by the World Health Organization (WHO) and licensed for use by a number of countries: CYD-TDV (Dengvaxia, Sanofi), for people with positive serum from 9 years of age and older, has been discontinued in many markets; and TAK-003 (Qdenga, Takeda), licensed by the Vietnamese Ministry of Health in May 2024, indicated for people from 4 years of age and older, does not require a pre-vaccination serological test, including 2 doses 3 months apart.

The protective efficacy of TAK-003 against virologically confirmed dengue was 80% after 12 months and the efficacy against hospitalization was 90% after 18 months.

With the advantage of being easy to deploy and not requiring serum screening, TAK-003 is expected to contribute to rapidly reducing the epidemiological and economic burden caused by dengue fever in Vietnam in the coming years.
