Ministry of Health: Dengue fever in Vietnam is increasing rapidly, if not drastically prevented, the disease may break out on a large scale?
Assess the current situation of dengue fever in Vietnam and in the future?
According to Official Dispatch 815/CD-BYT in 2022 of the Ministry of Health, it is said that now is the peak season of dengue fever. Dengue fever cases are continuously increasing in many localities across the country. The cause of the increase in dengue fever is due to the hot and humid weather plus a lot of rain, which has created favorable conditions for the larvae and larvae to develop, along with the people's awareness of dengue fever prevention. high, being subjective and negligent in the prevention of dengue fever.
With the current situation, the Ministry of Health predicts that in the near future the number of dengue cases will continue to increase and may break out on a large scale if the prevention of dengue fever in Vietnam is not implemented.

Suggest training for health workers on dengue fever on Vietnam surveillance and treatment?
According to Official Dispatch 815/CD-BYT in 2022, the Ministry of Health has proposed to chairpersons of People's Committees of provinces and centrally run cities to direct the implementation of the following tasks to prevent dengue fever blood:
- Organize the assessment of the dengue epidemic situation in the area, propose solutions to promptly overcome difficulties, exist and implement proactive measures to prevent dengue fever, thoroughly handle the epidemics. The outbreak does not allow the epidemic to break out in the area.
- Assign specific responsibilities to authorities at all levels with the task of directing and mobilizing political and socio-political organizations, sectors, and organizations to coordinate with the health sector to deploy a campaign to kill larvae and larvae to ensure ensure that all areas and households in epidemic-affected and at-risk areas must be inspected, monitored, and treated with tanks, water containers, items, waste, and breeding places for mosquitoes. to conduct forms of extermination of larvae and larvae according to the instructions of the health sector.
- Direct the Department of Health to strengthen inspection and close monitoring of the epidemic situation in order to detect new cases early, focusing on places with old outbreaks and risk of outbreaks. Well organize the collection and treatment of patients. Organize training for medical staff on dengue fever surveillance and treatment under the guidance of the Ministry of Health. Direct private clinics and treatment lines to strictly follow the guidelines for diagnosis and treatment. Timely and safe transit tracking. Make sure to have high molecular weight solution used in treatment according to the instructions of the Ministry of Health.
Strengthen the monitoring of dengue patients who are inpatient treatment during holidays and weekends to detect, promptly treat or refer severe cases of dengue fever. Consolidate and maintain the operation of the "dengue treatment group" and the "dengue fever prevention and control hotline" at medical examination and treatment units for regular consultation and information exchange. expertise, ask for support when needed. Instructing people to take effective measures to prevent disease and eliminate the nests of larvae and larvae.
- Directing the Department of Information and Communications, mass media agencies to deploy appropriate propaganda activities so that people understand the risks and dangers of dengue fever and actively respond to the epidemic. Measures to prevent diseases for individuals and the community, actively participate in the collection of waste materials containing water, places where larvae, larvae, mosquitoes develop and release fish into tanks, utensils containing domestic water. Continue implementing dengue prevention communication activities in response to the 12th ASEAN Dengue Fever Prevention Day peak right in June - July 2022.
- Direct the Department of Finance to ensure timely funding for medical units to carry out epidemic prevention and control activities, to prevent the dengue epidemic from spreading, spreading and prolonging.
Accordingly, localities need to implement the tasks and solutions according to the above content in the work of strengthening the prevention of dengue fever now and in the coming time.
How to effectively prevent dengue fever in Vietnam?
Pursuant to Section I of Decision 3711/QD-BYT 2014 of the Ministry of Health, there are guidelines on the main characteristics of dengue fever as follows:
“I. KEY CHARACTERISTICS OF DISEASE
Dengue hemorrhagic fever (DHF) is an acute mosquito-borne dengue virus (DEN) infection that can cause major epidemics. This disease is endemic in Vietnam, especially in the provinces of the Mekong Delta, the Northern Delta and the central coastal region
Due to different geographical and climate characteristics, the disease occurs all year round in the South and Central Vietnam, in the North and Central Highlands the disease usually occurs from April to November. In the North, the disease occurs less often in other months. because the weather is cold, with little rain, not suitable for the reproduction and activity of Aedes aegypti mosquitoes. Dengue disease develops the most in July, 8, 9, and 10 of the year.
Confirmed laboratory diagnosis by isolation/detection of genetic material or viral antigen in the blood within the first 5 days of fever or detection of dengue virus-specific IgM antibodies in serum from after day 5.
Causative agent: caused by Dengue virus belonging to the Flavivirus group, family Flaviviridae with 4 serotypes DEN - 1, DEN - 2, DEN - 3 and DEN - 4.
Incubation period and transmission: The incubation period is from 3-14 days, an average of 5-7 days. Patients are the source of infection during the period of fever, especially the first 5 days of fever when the blood has a lot of virus. Mosquitoes infected with the virus usually after 8-12 days after sucking blood can transmit the disease and transmit the disease for life.
Susceptibility and resistance: People who do not have specific immunity can be infected from infants to adults. After recovering from the disease, they will have lifelong immunity to the dengue virus type that causes the disease but not cross-protection with other types of dengue virus. If the patient is infected a second time with another type of dengue virus, the patient may become more seriously ill and more likely to develop dengue shock.
Disease vectors: The disease is not transmitted directly from person to person, but by mosquitoes that bite an infected person carrying the virus and then transmit the virus to a healthy person through the bite. In Vietnam, two species of mosquitoes that transmit dengue are Aedes aegypti and Aedes albopictus, the most important of which is Aedes aegypti.
Dengue prevention: Up to now, dengue disease has no specific treatment and no vaccine, so vector control activities, especially killing larvae/larvae, with the active participation of each household. family and the whole community is an effective measure in dengue prevention.”
Accordingly, at present, there is no specific medicine or vaccine for dengue fever in Vietnam, so people need to kill the larvae and larvae, which is the most effective measure to prevent dengue.
