A nation in the grip of dengue: How climate, pollution, and urbanization are feeding a relentless killer – the mosquito

Dengue has emerged as a persistent and escalating public health crisis in Bangladesh, reflecting both local vulnerabilities and a broader global threat. Between 2023 and 2025, the outbreaks have caused substantial morbidity and mortality across all age groups, driven by rapid urbanization, dense populations, poor sanitation, and climatic changes. Environmental degradation, including loss of green cover, pollution, and plastic accumulation, has further intensified mosquito proliferation, while demographic shifts reveal increasing vulnerability among children, juveniles, and young adults. Immediate, coordinated action – including strengthened public health infrastructure, vector control, and community awareness – is imperative to curb the ongoing outbreaks and mitigate the potential for regional and global spread.
