It is plainly evident that, over the past few years, dengue has rapidly transformed away from being a seasonal nuisance into a year-round public health crisis for Bangladesh - the record-breaking dengue outbreak of 2023, which claimed over 1,700 lives and infected hundreds of thousands, was something of a wake-up call, to that end.
According to a recent interview of Entomologist Kabirul Bashar, the expert clearly warns that areas outside Dhaka -- such as Barisal, Patuakhali, Comilla, and Cox’s Bazar -- are especially vulnerable due to lower immunity and weaker control mechanisms. He also warns of a potentially deadlier resurgence of the disease in August and September, which is why Bangladesh cannot afford to repeat the same mistakes of opting for reactive measures, fragmented coordination, and a lack of scientific rigour in mosquito control.
Our current efforts remain largely cosmetic: Spraying pesticides without larval surveillance, relying on outdated fogging methods, and failing to engage local governments in a meaningful way have left many districts dangerously exposed. We need a paradigm shift in how the administration carries out mosquito control. The proposed “KB Model,” which integrates scientific monitoring with targeted interventions, offers a promising blueprint.
But, as usual with our administrative measures, implementation will be key. The model demands training, equipment, and logistical support for city corporations and union councils alike.
We have to come to grips with the fact that dengue is no longer a seasonal headache; it is a persistent public health threat. With symptoms becoming harder to detect, early diagnosis and hospitalization protocols must also be strengthened. Of course, prevention remains our best defense, which means investing in research, exploring vaccine options, and building a decentralized mosquito control system that can respond swiftly and effectively regardless of location.
