One in Five Dengue Patients in Bangladesh a Child; Experts Warn of August-September Surge

Khairul Alam — The dengue situation in Bangladesh has taken an alarming turn over the past month and a half, with the virus spreading across every district in the country.

The shift in infection demographics is deeply concerning public health experts: children under the age of 15 now account for nearly 19% of all cases, meaning approximately one in every five dengue patients is a child.

According to data analyzed from the Directorate General of Health Services (DGHS), a total of 9,770 dengue cases and 32 deaths have been officially recorded this year.

Demographic Breakdown: Youth and Children Hit Hard

A closer look at the healthcare data reveals that the working-age population and young children are bearing the brunt of the current outbreak:

• Children and Minors: A total of 1,818 children aged 15 or under have been infected. Within this demographic, 584 are toddlers under five years old (representing 6% of overall patients), 571 are aged between 6 and 10, and 663 fall into the 11-to-15 age bracket.

• Working-Age Population: The workforce remains the single largest group affected, with individuals aged 16 to 50 making up 6,799 cases—exactly 70% of the total infections.

• Elderly: Citizens over the age of 50 account for 1,152 cases, or roughly 11.79%.

• Gender Distribution: Men comprise 61% of the total caseload, while women make up the remaining 39%.

A Massive Geographical Shift

Historically considered a Dhaka-centric illness before 2015, dengue has firmly established its presence nationwide. For the fourth consecutive year, the overwhelming majority of patients—76%—are being diagnosed outside the capital city.

Currently, Barisal Division has emerged as the worst-affected zone, logging 2,443 cases—meaning one in every four dengue patients in Bangladesh is from Barisal.

In comparison, Dhaka North and South city corporations have recorded 2,341 cases, while the rest of the Dhaka division sits at 1,172 cases.

Expert Analysis: The August-September Threat

Public health specialists and entomologists are sounding the alarm, warning that the worst is likely yet to come.

“Analyzing the current trajectory, the dengue situation could turn catastrophic during the upcoming months of August and September,” warned Dr. Kabirul Bashar, an entomologist and zoology professor at Jahangirnagar University. “If effective mosquito control measures are not executed immediately, the situation risks spiraling completely out of control.”

Dr. Bashar highlighted several high-risk districts requiring urgent intervention, including Barisal, Barguna, Pirojpur, Patuakhali, Bagerhat, Khulna, Chattogram, Cox’s Bazar, Chandpur, Cumilla, Dhaka, Gazipur, Mymensingh, Narsingdi, Manikganj, Munshiganj, and Narayanganj.

Public health expert Dr. Mushtaq Hussain elaborated on why infections are spiking across different age brackets:

“Working individuals are catching the virus due to frequent travel and poorly maintained work environments. Children, on the other hand, are highly vulnerable because they live in densely populated, unclean surroundings. To tackle this, we need integrated cleanliness drives—managing waste, not just stagnant water. Secondly, free diagnostic testing must be available immediately at the onset of a fever to ensure rapid, proper medical intervention.”

Government Interventions and Institutional Challenges

Former Director of the Disease Control Branch (CDC), Professor Dr. Be-Nazir Ahmed, pointed out a critical gap in local government capabilities, noting that if the capital failed to contain the Aedes mosquito effectively over the last 25 years, rural and semi-urban local government bodies with far fewer resources will face an uphill battle.

In response, the government is ramping up its countermeasures. Health and Family Welfare Minister Sarder Md. Sakhawat Hossain stated that nationwide cleanliness operations have been active for two months.

To ensure standardized medical care, a “Daily Treatment Protocol” created by specialists has been sent directly to the mobile phones and websites of all practicing doctors.

Furthermore, Professor Dr. Foara Tasmim, Additional Director General (Planning & Development) of DGHS, confirmed that all government hospitals are now providing free dengue testing, and maximum price caps have been enforced at private facilities to shield citizens from exorbitant out-of-pocket expenses.

Dedicated “Dengue Corners” have also been ordered across all public and private medical facilities to streamline incoming patient management.
