Hanoi: Dengue epidemic is complicated, the number of cases increases

The disease of dangerous dengue transmitted by mosquito bites is tending to increase strongly in Hanoi when only in July, the number of cases accounted for over 50% of the total number of dengue cases recorded since the beginning of the year.

The number of dengue cases increased sharply in Hanoi

On August 12, Dr. Nguyen Nhat Cam, Director of Hanoi Preventive Health Center, said that from the beginning of the year, Hanoi has recorded 693 dengue fever cases scattered in 164 communes and wards of 29 districts. , in which there are no deaths.

'Dengue season in Hanoi starts from April to November every year. Therefore, at this time in Hanoi is the season so the number of patients started to increase. While January recorded only 21 cases of dengue, in February there was 1 case, March, April of 15 cases each month, from May, the number of patients began to increase with 69 cases.

In particular, since June the number of patients has increased nearly 3 times in May with 168 cases and peaked in July with 357. The number of cases decreased compared to the same period of the year (2009), only accounted for 38%, but increased compared to the same period in 2014. However, there are outbreaks of nature, not yet concentrated, complicated outbreaks, 'said Dr Cam.

Also according to Mr. Cam, through epidemiological investigation, dengue fever is mainly seen in adults, in children under 15 years of age, the incidence is very low, accounting for only 13%. In Hanoi, in urban districts such as Hoang Mai, Hai Ba Trung, Ha Dong and intra-urban districts are rapidly urbanizing as Thanh Tri concentrates the largest number of patients.

In the whole country, according to statistics of the Ministry of Health, since the beginning of the year, the country has 19,753 cases of dengue fever, 12 deaths, of which many provinces / cities have accumulated cumulative increases. Compared to the same period in 2014, such as Ho Chi Minh City, Dong Nai, Soc Trang, Dong Thap . In Hanoi , 362 dengue cases have been recorded in 25/30 districts / towns.

Assoc. Prof. Dr. Tran Dac Phu, Director of the Department of Preventive Medicine - Ministry of Health said that compared to the period of 2010 - 2014, the number of people suffering from dengue in 2015 decreased significantly but the development of the epidemic is still quite complicated especially in the southern region. In particular, dengue outbreaks often break out strongly in the rainy season.

Increased because of the translation cycle?

Although dengue fever is still disseminated, there is no big outbreak, the number of cases is still under control but experts also fear that the number of new cases of dengue this year in Hanoi will increase by Enter the translation cycle.

'Through monitoring of dengue epidemic epidemics for many years in Hanoi, Hanoi Health sector has forecasted that in 2014 and 2015, it is possible to increase the number of diseases because of the epidemic cycle (after 4-5 years since 2009, the year of a big epidemic in Hanoi) ' , Dr Cam said.

In response to this risk, Hanoi's health sector has timely advised the People's Committee of the City and all levels to drastically implement anti-epidemic measures. Propagate people about dengue fever and preventive measures in many ways; timely monitoring of cases of patients or suspected suspects at medical facilities and in the community; organizing a campaign to clean the larvae environment at the household; spraying chemicals to kill adult mosquitoes in large areas to control the outbreak and spread .

However, when propagating and spraying mosquitoes in some households, people do not cooperate in epidemic prevention and control such as: Do not open health workers to the sanitation inspection houses to kill bugs or spray chemicals to kill mosquitoes; not report to local health officials when sick; Do not take the initiative and do regular killing of larvae in and around your home. Besides, people's knowledge of diseases is still limited, for example: Thinking that clean houses will not have mosquitoes; Thinking about prevention is mainly spraying chemicals to kill adult mosquitoes, disregarding sanitation, killing larvae in and around your home.

Meanwhile, people's habits and habits make the dengue transmission agent have a chance to develop. As people still have the habit of storing water but not putting fish to kill larvae. Or a vase of flowers on the altar, a vase of flowers for a long time, water standing in a pot of ornamental plants filled with bugs, bottles, soft drinks cans . throwing out into the garden can also stagnate water and be a place of birth Ideal boiling of dengue mosquitoes.

Regarding the circulating dengue fever, Associate Professor Dr. Tran Dac Phu said that all 4 types of dengue fever are circulating and without cross-immunity, so this type of dengue fever still has the risk of dengue fever. Other types and the next time often show worse than the last time.

Therefore, in order to prevent dengue for ourselves and those around us, every family needs to actively kill larvae in and around the house, need to change the habit of not storing water in the house, pouring water bottles flowers, ornamental plants, clearing the garden, not leaving the debris, the bottle of water in the garden . are the habitats of the larvae that grow into mosquitoes; sleep curtain; cooperate with health workers when there are patients or outbreaks. Especially when there is a sudden high fever over 2 days, it is necessary to immediately seek medical treatment to avoid death.
