Studying dengue across Bangladesh in 2026

Throughout 2026, Bangladesh has borne witness to yet another dengue epidemic, with deaths and dengue cases increasing by the week while showing no signs of slowing down. Despite the cleanliness drives, despite the preventative measures taken, the number of cases continues to rise. This article will look into the number of cases and deaths pertaining to dengue, in order to paint a picture as to where dengue is hitting the Bangladesh the worse and in need of attention.

Observations made in this article are based on the compiled data and information found in the Dengue dashboard, created by the Directorate General of Health Services (DGHS).

Number of dengue cases by district
When looking at the cases on the Dengue Dynamic Dashboard, Dhaka areas outside of the City Corporation are hit the hardest with dengue cases, followed by Khulna and Chattogram, with Barishal following close behind. Between DNCC (Dhaka North City Corporation) and DSCC (Dhaka South City Corporation), it is the latter that is hit with the most dengue cases. Sylhet is the one district that not only has the lowest number of reported dengue cases, but the only one where said number never touches the thousands digit.

Number of dengue-related deaths by district
On an alarming note, DSCC has highest record of dengue-related deaths, followed by Khulna. Though DNCC is the third most-affected district, unlike its southern counterpart, it isn’t hit as badly. On the other hand, Sylhet is hit the least, followed by Rangpur. On the note of areas affected in Dhaka, Dhaka areas outside City Corporations has the least dengue-related deaths, despite it having the most dengue-related cases, while the opposite is true for DSCC. Deaths in Rajshahi, Chattogram, and Barishal are almost similar.

Gender distribution of dengue cases and deaths
When looking at the dengue cases and deaths distributed among genders, men are more likely to be affected by dengue than women are (Men’s ~62.3% vs. Women’s ~37.7%). When it came to deaths, the distribution is almost evenly split, with women leading by a mere 4.2%. From the looks of things, men are more likely to catch dengue than women are. As to why this is the case, it is likely that most of the men who are afflicted are those who are employed and go outside often, especially when looking at the age range of those afflicted.

Dengue cases and deaths by age group
According to the reported data, the age group affected the most by dengue is 21-30, with those aged 75 and older being the least affected. When it comes to deaths, most of those aged 26-30 have died to dengue, with those who are older and younger experiencing the least deaths. As a matter of fact, dengue-related cases and deaths are concentrated around the 21-30 age range, with the number going down the lower or higher the age range gets.

Without further context, this doesn’t paint a definitive picture on the dengue epidemic; merely a model of what could be happening. But looking at the data, it seems that men, those who live in Dhaka areas outside of the City Corporation, and aged between 20-30, are the ones most afflicted by dengue; those who resided in DSCC were likely to succumb to the disease, for what reasons, whether it’s related to diminished healthcare or poor living conditions, is unclear. However, with this data, proper measures and the resources could be efficiently distributed to deal with and hopefully curb the dengue epidemic.
