Due to the impact of storm No. 3, many provinces and cities have been flooded in recent days. This is a favorable condition for mosquitoes that transmit dengue fever to breed and develop.
Experts say that the risk of disease outbreaks will increase in the coming time if proactive and synchronous disease prevention measures are not implemented.

According to the report of the Hanoi Center for Disease Control (CDC), during the week (from September 6 to September 13), the whole city recorded 227 cases of dengue fever (an increase of 37 cases compared to the previous week).
Among the districts with many patients, Dan Phuong leads with 57 cases, followed by Ha Dong with 17 cases, Hai Ba Trung with 15 cases, Thach That with 15 cases...
Since the beginning of 2024, Dan Phuong district has recorded 810 cases of dengue fever. This is also the locality with the highest number of dengue fever cases this year in the city.
In addition, the city also has 9 more dengue fever outbreaks, including 3 active outbreaks in La Thach village (Phuong Dinh commune), Tho Vuc village (Dong Thap commune), cluster 1 (Ha Mo commune) of Dan Phuong district; 2 outbreaks in Nghia Dung street (Phuc Xa ward, Ba Dinh district)...
According to the Center for Disease Control of Quang Ninh province, from the beginning of 2024 to now, the whole province has recorded 127 cases of dengue fever, of which the areas with the highest number of cases are Ha Long (56 cases), Cam Pha (19 cases), Uong Bi (14 cases).
Most of the cases were recorded sporadically. However, the provincial health sector recorded a number of clusters of cases in Hong Ha ward (Ha Long city); Yen Thanh and Thanh Son wards (Uong Bi city); and Cua Ong ward (Cam Pha city).
In Quang Yen town, from September 13 to 17, the town's Medical Center received and treated 5 cases of dengue fever. Of which, 1 case had complications of mucosal bleeding and thrombocytopenia, and was transferred to a higher level for treatment.
It is known that the 5 cases of dengue fever in Quang Yen Town are all new outbreaks in Tien An Commune and Quang Yen Ward, Yen Giang.
The Quang Ninh Provincial Center for Disease Control warns that dengue fever is currently entering its annual peak period, usually occurring from September to November.
The weather during this period is unpredictable, along with heavy rain, creating favorable conditions for mosquitoes to develop and spread disease.
Assessing the current dengue fever situation in the city, Deputy Director of Hanoi CDC Khong Minh Tuan said that dengue fever occurs year-round but the number of cases often increases during the rainy season.
In particular, from September to November every year is considered the "hot" period of dengue fever due to humid weather and heavy rain, creating a favorable environment for Aedes mosquitoes to breed and develop.
Hanoi has now entered the peak phase of the dengue fever epidemic with complex and unpredictable weather conditions combined with heavy rain. Monitoring results at some outbreak areas recorded insect indexes exceeding the risk threshold. Therefore, the number of dengue fever cases is forecast to continue to increase in the coming time.
According to Mr. Tran Dac Phu, senior advisor of the Vietnam Center for Public Health Emergency Response, after floods, diseases transmitted by vectors (intermediate hosts) such as mosquitoes are at high risk of emerging.
A typical example of this is dengue fever. To prevent the disease, many people make the mistake of only preventing mosquito bites at night. While the mosquito that transmits dengue fever bites during the day, biting most strongly in the early morning and late evening. This type of mosquito often rests in dark corners, or on clothes, blankets, clotheslines and household items.
Mosquitoes that transmit dengue fever only lay eggs in clean, clear water containers. Therefore, if people believe that mosquitoes lay eggs in dirty places, sewers, and only focus on cleaning up stinky, stagnant sewers, they will not be able to prevent dengue fever at all.
Also according to Mr. Khong Minh Tuan, in recent days, the city CDC has coordinated with relevant units to monitor environmental sanitation activities, disease prevention and control in flooded areas affected by heavy rains and floods in the districts of Chuong My, Thach That, Dong Anh, Phu Xuyen, My Duc, Quoc Oai, etc.
Although dengue fever is a very old disease, the concern is that each epidemic has its own difficulties. One of the difficulties is that when infected, people often go straight to clinics or private hospitals, not to public hospitals or health stations.
That leads to the inability to monitor cases early and handle outbreaks early. Meanwhile, if the outbreak is not handled in the first 3 days, by the 5th day, there is a risk of an outbreak and spread. When the outbreak has increased to 10 patients, the possibility of it becoming 20-30 patients soon after is very fast.
Faced with the risk of disease outbreaks after storm No. 3, Dan Phuong District Medical Center has urgently deployed environmental disinfection spraying at many heavily flooded areas in the communes of Hong Ha, Trung Chau, and Tan Hoi. In addition, district medical staff also conducted environmental disinfection spraying, instructed people on how to treat water sources for drinking, daily activities, and measures to prevent and control epidemics after floods...
To effectively prevent and control dengue fever, according to Mr. Khong Minh Tuan, medical centers of districts, towns and cities need to strengthen monitoring, early detection, thorough and timely handling of dengue fever cases and outbreaks occurring during and after floods; maintain monitoring and detection of patients at decentralized medical facilities.
At the same time, strengthen propaganda and instruct people in flood-affected areas on environmental treatment measures and ways to kill mosquito larvae.
Killing mosquito larvae is a sustainable measure to prevent and control dengue fever, while spraying chemicals to kill mosquitoes is only an emergency measure.
Therefore, it is necessary to propagate and mobilize people to voluntarily destroy mosquito larvae by small actions such as: Covering water containers, releasing fish into large water tanks, turning upside down water containers, cleaning up waste around the house that can be a place for rainwater to accumulate, including bottles, boxes, tree holes, etc. This will limit the spread of disease in the community.
Many people think that mosquitoes that transmit dengue fever only live in stagnant public ponds, sewers, etc. However, Aedes mosquitoes live in places with clear water that has been left for a long time, such as aquariums, flower vases, rockeries, rainwater stagnant in broken bowls in home gardens, alleys, terraces, construction sites, etc. Therefore, it is necessary to remove stagnant water containers that are places for Aedes mosquitoes to breed and develop.
It is necessary to clean the house, turn over all mosquito hiding places to kill larvae, then spray insecticide to kill adult mosquitoes.
To kill mosquitoes more effectively, spray in the morning, because dengue mosquitoes are most active during the day, most active in the early morning hours and before sunset. It should be noted that insecticide sprays are effective for 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.
Regarding treatment, many people think that when having dengue fever, you should only drink electrolytes, not 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 many 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.
