According to the Hanoi Department of Health, the number of dengue fever cases in Hanoi has increased continuously over the past three weeks.
Results of monitoring dengue fever prevention and control in some districts show that the insect index is higher than the risk threshold, and the number of cases is forecast to continue to increase in the coming time.

| According to the Hanoi Department of Health, the number of dengue fever cases in Hanoi has increased continuously over the past three weeks. |
Specifically, during the investigation, the monitoring indexes of mosquito larvae, Aedes mosquitoes transmitting dengue fever, and the BI (Breteau index) play an important role in determining the situation.
Accordingly, if the BI index is recorded at 20 or higher (regulation in the Northern region), the monitoring facility is at high risk of an outbreak.
With this database, monitoring results at the 2024 outbreak in Dan Phuong district and old outbreaks in 2023 last week showed that the insect index in some places exceeded the risk threshold by 2-5 times.
Specifically, on June 17 and 18, monitoring at two outbreaks in Dan Phuong district showed that the BI index was twice the risk threshold; in which Dong Van village had BI=42.8 and cluster 1 in Doai Khe village had BI=40.
In these areas, larvae nests are found mainly in water tanks, buckets, water containers, and flower pots.
In addition, monitoring of old dengue outbreaks since 2023 such as in Phuong Tu commune (Ung Hoa district) recorded BI=110 (5 times higher than the risk threshold); Yen Vien town (Gia Lam district) had BI=40; Kim Ma ward (Ba Dinh district) had BI=40.
Deputy Director of the Hanoi Department of Health Vu Cao Cuong said that the dengue fever epidemic this year will have complicated developments. The reason is due to climate conditions, along with many places where people have the habit of littering, storing rainwater and domestic water, creating an environment for disease-carrying mosquitoes to grow and develop.
Currently entering the peak month of dengue fever season, therefore, Deputy Director of the Department of Preventive Medicine, Ministry of Health Nguyen Luong Tam said that the capital's health sector needs to strengthen coordination with relevant units to synchronously deploy epidemic prevention measures, focusing on eliminating mosquito larvae.
Along with that, the city needs to mobilize the participation of sectors, levels, and socio-political organizations in preventing and fighting dengue fever.
This week, in areas where insect monitoring results exceed the risk threshold, the Hanoi Department of Health has proposed organizing environmental sanitation campaigns, mosquito larvae eradication campaigns, and chemical spraying campaigns to kill adult mosquitoes.
In addition, units need to inspect and monitor disease prevention and control work in areas with many cases, complicated outbreaks, and high-risk areas, in order to assess the situation, thereby implementing appropriate and timely measures. Particularly for Dan Phuong district, the district People's Committee needs to continue to direct relevant units to thoroughly handle the outbreak in Dong Thap commune, including effective spraying of chemicals on a large scale.
To completely eliminate disease-causing mosquitoes, Deputy Director of Hanoi CDC Khong Minh Tuan recommends that people should pay attention to regularly checking household items such as: vases, barrels, jars, broken pieces, bottles, stagnant water waste, water storage items...
These items should be turned upside down when not in use. Eliminating the breeding and development environment of mosquitoes is the most fundamental, long-term, effective and economical disease prevention measure.
Along with that, promote communication to the community about the epidemic situation and prevention and control measures so that people can proactively implement timely disease prevention and treatment measures, limiting serious cases and deaths.
Since the beginning of 2024, the city has had 856 cases of dengue fever (an increase of more than 1.7 times compared to the same period in 2023). The city has recorded 14 dengue fever outbreaks, 10 of which have been controlled. Of the 4 active outbreaks, 3 are in Dan Phuong district and 1 is in Dong Da district.
Particularly, the outbreak in Bai Thap and Dong Van villages (Dong Thap commune, Dan Phuong district), from May 8, 2024 when the first patient was detected, until now after more than 1.5 months, there have been 89 cases. This is identified as a "hot spot" that requires focused implementation of prevention measures.
There is currently no specific treatment for dengue fever, mainly treating symptoms and monitoring warning signs. Patients need to be hospitalized when they have one of the following signs: mucosal bleeding, bleeding from the teeth, nose, or digestive tract; abdominal pain in the liver area; severe vomiting; rapid decrease in platelets and concentrated blood; and little urine.
With dengue fever, there are mistakes in treatment that make the disease worse that people need to avoid at all costs. Accordingly, the symptoms of dengue fever are easily confused with common viral fever, making patients subjective and the disease easily becomes worse, causing many complications, even life-threatening.
Dengue fever is divided into 3 levels: Mild, with warning signs and severe. Patients often subjectively do not go to the doctor but self-treat.
In mild cases, patients may be advised to monitor at home but still need to go to the doctor for diagnosis, treatment and close monitoring.
In severe cases, patients may experience dangerous complications such as internal bleeding, brain damage, liver and kidney damage, and even death if not detected promptly.
Most patients mistakenly believe that once the fever is gone, they are cured because the fever goes down and the body feels more comfortable. However, in reality, the most dangerous stage is after the high fever stage.
At this time, the patient needs to be closely monitored by the doctor and rest absolutely, limit heavy exercise and travel a lot because after 2-7 days, platelets can decrease severely and plasma can escape, the patient may experience symptoms of subcutaneous bleeding, nosebleeds, etc.
Depending on the severity and complications of the disease, it can lead to internal bleeding, pleural effusion, gastrointestinal bleeding, dengue shock, and even death.
People with dengue fever often have a high fever continuously, so to reduce the fever quickly, they take fever-reducing medicine without following the correct dosage instructions.
There are even many cases of using the wrong antipyretic drugs such as using aspirin and ibuprofen instead of paracetamol, leading to more serious bleeding in the patient, possibly severe gastric bleeding, which is life-threatening.
Many people think that mosquitoes that transmit dengue fever only live in stagnant public water, sewers...
However, Aedes mosquitoes reside in places where water has been left for a long time, such as aquariums, flower vases, rockeries, rainwater stagnant in broken bowls in home gardens, alleys or terraces, construction works, etc. Therefore, it is necessary to remove stagnant water containers that are places for Aedes mosquitoes to breed and develop.
To avoid dengue fever-carrying mosquitoes, many people think that it is okay to spray insecticide at any time. However, the first way to kill mosquitoes is to clean the house, turn over all mosquito hiding places to kill larvae, then spray insecticide to kill adult mosquitoes.
To effectively kill this mosquito, spray in the morning. Because dengue mosquitoes are active during the day, they are strongest in the early morning hours and before sunset. It should be noted that insecticide sprays have a good effectiveness period of 6 months from the time of spraying.
Many people believe that once they have had dengue fever, they will not get it again. This is not necessarily true. Dengue fever is caused by the Dengue virus, which has 4 strains: DEN-1, DEN-2, DEN-3 and DEN-4. All 4 strains of the virus are capable of causing the disease.
Therefore, if a person has had dengue fever, during the illness the body can create antibodies. However, the immunity created is only specific to each individual strain. The patient may not be reinfected with the old strain of the virus, but can still be infected with the new strain, so dengue fever can recur.
Many people think that when having dengue fever, you should only drink electrolytes and not drink coconut water because it does not have a rehydration effect and it is difficult to detect complications.
This is completely wrong, in dengue fever, high fever for several consecutive days will cause the patient to become dehydrated and lose fluids. The simplest way to compensate for fluid loss is to give the patient Oresol.
However, many patients have difficulty drinking Oresol. This can be replaced by drinking coconut water, orange juice, grapefruit juice, lemon juice to compensate for the lost fluid. Moreover, the above fruits contain many minerals and vitamin C, helping to strengthen resistance and increase the strength of blood vessel walls.
Many parents have the wrong treatment when their children have dengue fever. When they see a bruise on their child, they think that cutting the wound to remove some of the toxic blood will help them recover quickly.
This can lead to uncontrolled bleeding. This is an entry point for bacteria, which can cause life-threatening blood clotting disorders in children.
