Bangladesh’s dengue outbreak has taken a sharply deadlier turn in September, with 74 people dying in just 16 days, already 72% more than the 43 deaths recorded throughout August, as hospital admissions surged to their highest daily level of the year.
The pace of deaths has more than tripled.
September has so far claimed an average of 4.6 lives a day, compared with about 1.4 in August, according to a Dhaka Tribune analysis of Directorate General of Health Services (DGHS) data.
Seven more people died and 1,753 were hospitalised in the 24 hours to Wednesday morning, taking this year’s toll to 171 deaths and 56,916 hospital admissions.
The latest caseload is the highest recorded in a single day this year, underscoring how rapidly the outbreak has intensified since the monsoon.
The deterioration is not confined to deaths.
Bangladesh recorded 9,206 hospitalizations in July before cases more than doubled to 20,536 in August.
September is now accumulating patients at an even faster pace, with more than 1,000 admissions being reported almost every day.
Of Wednesday’s 1,753 admissions, 744 were in Dhaka and surrounding areas, while Khulna recorded 349, Barisal 186, Chittagong 177, Rajshahi 153, Mymensingh 83, Rangpur 53 and Sylhet nine.
The seven latest deaths, however, all occurred outside Dhaka -- three in Khulna and one each in Chittagong, Mymensingh, Rajshahi and Rangpur -- highlighting the outbreak’s widening geographical reach.
Dhaka nevertheless accounts for the largest share of fatalities this year, with 80 deaths, followed by Khulna with 32, Mymensingh 18, Chittagong 16, Barisal 13, Rajshahi eight, Rangpur three and Sylhet one.
Public health experts warned that hospital figures alone do not necessarily reflect where transmission is highest because critically ill patients from districts are often referred to Dhaka.
Renowned entomologist Professor Kabirul Bashar of Jahangirnagar University, said: “Dengue is no longer concentrated in Dhaka. Cases are rising in several districts, including Khulna, Patuakhali, Bagerhat, Chapainawabganj, Bandarban, Pirojpur, Chittagong, Munshiganj and Narayanganj.”
“Dhaka hospitals show higher numbers partly because patients from across the country come to the capital for advanced treatment. Controlling dengue requires effective vector management and community participation, not merely insecticide use.”
Former DGHS disease control director Professor Be-Nazir Ahmed said: “Fogging alone cannot control dengue. The most effective measure is to identify and destroy Aedes mosquito breeding sites. At the same time, rapid diagnosis and timely treatment are crucial to preventing severe illness and deaths.”
The trajectory has worsened sharply since July, and experts fear infections and deaths could continue rising through November without stronger preventive measures.
With September only halfway through, its death toll has already far surpassed August’s, while the latest record hospital admissions suggest the outbreak has yet to peak.
