The whole country has currently recorded more than 93,800 cases of dengue fever, with 26 deaths. In Hanoi, the number of dengue fever cases continues to increase; the entire city has recorded over 15,300 cases. This year’s patients with severe dengue fever typically have complicated developments, many of them are young but have severe complications when infected.
Dengue fever cases in Hanoi continue to increase, experts explain the reason
According to statistics, in week 38/2023, the country recorded 5,758 cases of dengue fever . Compared to last week, the number of cases decreased by 4.3%. In particular, the number of hospitalizations compared to the previous week decreased by 5.6%. Accumulated from the beginning of the year until now, the country has recorded 93,814 cases and 26 deaths. Compared to the same period in 2022 (228,490/117), the number of cases decreased by 58.9%, deaths decreased by 91 cases.
In Hanoi, according to statistics, this week, the city continued to have nearly 2,600 more cases of dengue fever (an increase of 1.5 times compared to the first week of September 2023). Thus, cumulatively in the first 9 months of 2023, the city has recorded 15,354 cases of dengue fever (more than 3 times more than the same period in 2022), including many complex, long-lasting outbreaks. Patients are distributed in 30/30 districts, towns and cities; 557/579 communes, wards and towns.
Districts in Hanoi with many patients from the beginning of the year until now are: Hoang Mai (1,141 cases), Phu Xuyen (951 cases), Thanh Tri (928 cases), Thach That (924 cases), Ha Dong (904 cases), Dong Da (852 cases), Cau Giay (846 cases), Nam Tu Liem (754 cases), Dan Phuong (744 cases), Thanh Oai (723 cases).
Talking to Health & Life reporters , Dr. Vu Trong Duoc – Head of the Northern Dengue Office, Central Institute of Hygiene and Epidemiology said that Hanoi recorded the highest number of dengue fever cases, which is a general trend of epidemiology of the whole region, because normally Hanoi as well as the provinces of the Northern region often record cases starting to increase from July and August and peaking in September and October. In addition, this year there are also Hot weather and lots of rain are very favorable for vector mosquitoes to develop at high densities, spreading the Dengue virus more strongly in the community.
In addition, Hanoi has characteristics that make dengue fever increase faster than other provinces in the Northern region, which are a lot of travel and trade, dense population making it easy for mosquitoes to spread. spread Dengue virus more. If there are mosquitoes infected with the virus, there will be ‘conditions’ for it to spread more strongly than in other areas.
At the National Hospital of Tropical Diseases, according to statistics, since September, the number of patients with dengue fever has increased significantly. Currently, this medical facility is treating more than 200 dengue patients in many departments. Patients were transferred from many northern provinces, the majority of which were Hanoi.
The patient with dengue fever was young but the course was severe
According to Doctor II Nguyen Trung Cap, Deputy Director of the National Hospital of Tropical Diseases, dengue fever patients hospitalized have tended to increase rapidly in recent days. On average, every day the hospital receives 4-5 cases with warning signs of dengue shock with the following symptoms: Abdominal pain, liver pain, mucosal bleeding, low platelets, and concentrated blood.
“These cases need to be detected and treated actively because after only 4-6 hours, the patient can go into dengue shock, then the patient will become critically ill very quickly, even die. Therefore, medical facilities and patients must pay attention to go to the hospital or receive correct and timely treatment” – Doctor Cap noted.
About 5% of dengue patients being treated at this hospital are in severe condition. According to Dr. Pham Van Phuc – Deputy Head of Intensive Care Department, National Hospital of Tropical Diseases, this year’s severe dengue fever patients in particular have complicated developments because they have many different medical conditions, including: Hemorrhage due to fluid drainage, shock due to thrombocytopenia and bleeding… Notably, among the dengue patients requiring mechanical ventilation in the Intensive Care Department, most are young patients but their condition is very severe.
The dengue virus types circulating in 2023 are mainly D1 and D2 and there is no difference from the virus types circulating in recent years.
However, predicting the dengue epidemic situation in the coming time, the Department of Preventive Medicine said that, according to the World Health Organization, in 2023 and 2024 climate change and the El Nino phenomenon may accelerate the epidemic. promotes mosquito reproduction, increasing the transmission of dengue fever and other mosquito-borne diseases.
It is forecasted that in the coming time, because the rainy season is at its peak, the number of infections will continue to be complicated and tend to increase if disease prevention measures are not drastically implemented, especially mosquito eradication activities. , kill larvae and larvae in localities.
According to the Department of Preventive Medicine, Ministry of Health, there is currently no vaccine to prevent dengue fever and no specific treatment. The main and effective prevention measures are to kill mosquitoes and larvae/larvae. and prevent mosquito bites. To actively prevent disease for yourself, your family and everyone around you, the Ministry of Health strongly recommends that people take the following disease prevention measures:
Cover all water containers tightly to keep mosquitoes from laying eggs.
Every week, carry out measures to kill larvae/larvae by placing fish in a large water container; Wash small and medium-sized water containers, turn over non-water containers; change water in flower vase/flower vase; Put salt or oil in the bowl of water at the base of the cupboard.
Weekly remove waste materials and natural water holes that do not allow mosquitoes to lay eggs such as bottles, jars, bottle pieces, coconut shells, broken jar pieces, old tires/tyres, bamboo holes, leaf sheaths…
Sleep under mosquito nets and wear long clothes to prevent mosquito bites even during the day.
Actively coordinate with the health sector in chemical spraying to prevent and control epidemics.
When you have a fever, go immediately to a medical facility for examination and treatment advice. Do not self-treat at home.
