The capital is experiencing an outbreak of dengue as the rainy season strated.

As many as 707 people have been infected with dengue viruses and two of them died in the capital during a period from January to June 20. Dengue cases are likely to increase in the coming days.

Health experts have advised city residents to remain cautious as the mosquito-borne disease breaks out mainly in urban areas during rainy season. They advised people to keep the surroundings of their homes clean and destroy possible dens of dengue mosquitoes.

According to a report of the Health Emergency Operations Centre and Control Room of the Directorate General of Health Services (DGHS), around 707 patients were admitted with dengue infection to different hospitals in the capital from January 1 to June 20 this year.

Of them, two dengue patients died in Asgar Ali Hospital and BRB Hospital in the capital in April this year, the report said.

According to the report, around 284 people were admitted with dengue in hospitals in the capital from June 11 to June 20. The average rate of admitting with dengue fever in hospitals in last 10 days is around 28.

Sources at different public and private hospitals in the capital said people of different city areas, including Dhanmondi, Gulshan, Baily Road, Shantinagar, Eskaton, Segunbagicha and Old Dhaka, are being infected with dengue viruses. 

“The number of dengue patients is likely to increase in the peak rainy season. Dengue cases may increase during rainy season that usually begins in July,” ASM Alamgir, principal scientific officer of the Institute of Epidemiology, Disease Control and Research (IEDCR), told the daily sun.

“We have to remain cautious for prevention of the disease before it is too late. We have to keep our neighborhoods clean and destroy all possible dens of Aedes mosquito which is responsible for the disease,” he suggested.

ASM Alamgir further said if city residents do not remain alert and do not take any preventive measure, the disease may spread in cities, towns and villages.

Earlier, some 1192 people were infected and two died in November last year and 293 infected and one died in December the same year.

In 2018, some 26 patients were infected with dengue virus in January, seven in February, 19 in March, 29 in April, 52 in May, 295 in June, 946 in July, 1,796 in August, 3,087 in September, 2,406 in October, 1,192 in November and 293 in December. A total of 26 patients died last year, the DGHS report said.

While talking to the daily sun, some health experts said people are being infected with dengue virus in the capital due to fast breeding of aedes mosquito.

Although the disease spreads mainly in the rainy season from April to October, it may infect people at anytime round the year, an expert said.

“There are three types of dengue: dengue fever, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS),” Muhammad Shakhawat Hossain, medical officer of Health Emergency Operations Centre and Control Room, said.

Aedes mosquito breeds mostly in flower tubs, abandoned cans, pots, cups, and coconut shells containing clean water in and around houses, particularly in urban areas, he said.

Health experts said aedes mosquito, which is responsible for dengue, breeds mostly in flower tubs, abandoned cans, pots, cups, and coconut shells containing clean water in and around 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 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 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 produce aedes larvae in large number. The residents of Dhaka use relatively smaller plastic drums, plastic buckets and larger water tanks to store water from piped water source.
