Stay alert to dengue, doctors advise

Health experts have advised people to remain alert to the danger of dengue and chikungunya as the capital sees an outbreak of these diseases during this rainy season.

 

According to a report of Health Emergency Operations Centre and Control Room of Directorate General of Health Services (DGHS), 992 dengue patients were admitted to different hospitals in the capital from January 1 to July 28 this year while eight patients died of dengue diseases.

 

 “Some 638 patients were infected with various types of dengue diseases from July 1 to July 28 while four people died of dengue in the current month. Some 59 dengue patients have been admitted to different hospitals of the capital,” Borhan Uddin, the on-duty medical officer of the control room, told the daily sun.

 

He said, “There are three types of dengue - dengue fever, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). As of July 28, most of the patients were suffering from dengue fever while there is still one patient of DHF and another of DSS.”

 

The Aedes mosquito larvae, responsible for dengue fever, have been found in various areas, including some posh areas of the capital.

 

The DGHS control room source said eight people, including three children and a physician, died of dengue diseases this year while four died in the month of July.

 

It said a child aged eight years died of dengue in Dhaka Shishu Hospital on July 8, another child at Dhanmondi Central Hospital on July 15, a patient died at Dhaka Shishu Hospital on July 16, a man  died of dengue at BIRDEM hospital on July 26, three dengue patients died in June and another died in January this year.

 

Hospital sources said a dengue outbreak occurred in different parts of the capital, including Segunbagicha, Bailey Road, Banglamotor, Eskaton, Kathalbagan, Kalabagan, Dhanmondi, Mohammadpur, Mirpur and Tejgaon areas during this rainy season.

 

A survey of Dhaka South City Corporation (DSCC), conducted by its health department  between June 25 and July 15 at all of its 57 wards under five zones, found that the larvae of the Aedes mosquito exist in one of the three houses.

 

After unveiling the findings at a function at Banglamotor on Saturday, DSCC Mayor Mohammad Sayeed Khokon said the study found that the posh residential areas, including Dhanmondi, Kalabagan and Segunbagicha, have been identified as the highest breeding areas of Aedes mosquito.

 

He said as they identified that 46 percent of the houses are breeding places of Aedes larvae in Segunbagicha area of the capital.

 

Sayeed Khokon said the presence of Aedes larvae in Old Dhaka was less while 45 percent of the houses at Dhanmondi, 41 percent at Kalabagan and 46 percent at Segunbagicha were detected as Aedes spots.

 

Talking to the daily sun, the DSCC mayor said on average, 45 percent of houses have been found as breeding places of Aedes mosquito in wards no. 15, 17 and 20.

 

He further said they have started their second phase of the anti-mosquito drives and it will continue for two weeks to destroy the breeding places of Aedes mosquito.

 

In the situation, health experts advised people to keep their houses and neighbourhoods clean to prevent the mosquito-borne diseases as a recent survey found the presence of Aedes mosquito, responsible for viral dengue disease, in different areas of the capital.

 

“Dengue cases may increase during this rainy season that usually begins in July. People have to keep their houses clean as a preventive measure,” ASM Alamgir, a senior scientific officer at the Institute of Epidemiology Disease Control and Research, told the daily sun.

 

He said if the city dwellers do not remain alert and do not take the preventive measures, these diseases may spread in villages, other cities and towns.

 

Health experts said the Aedes mosquito, which is responsible for dengue disease, breeds mostly in flower tubs, abandoned cans, pots, cups, and coconut shells containing clean water in and around the houses, particularly in urban areas.

 

A joint study conducted by the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), in collaboration with some national and international institutions, said the dengue viruses are responsible for over 100 million confounder adjustments.

 

“Rainfall, temperature, and relative humidity also significantly affected the mean abundance of mosquitoes. Proper use, disposal and recycling of the containers that effectively produce large numbers of Aedes vector mosquitoes may decrease the risk of arbovirus transmission,” it said.

 

The study observed that plastic drums, plastic buckets, water tanks, clay pots, and flower tubs are producing a large number of Aedes larvae and pupae while the residents of Dhaka use relatively smaller plastic drums, plastic buckets and larger water tanks to store water from piped water source.
