South Asia is a frontline region in the global climate change war. Bangladesh, a riverine-delta country, is bearing the full force of climate-related impacts. Longer-than-usual rainy seasons, high temperatures, and high humidity have led to an explosion of mosquito populations that are exacerbating this dengue crisis.
An overlooked factor in the dengue crisis is demography. South Asia, especially Bangladesh, is one of the world's most densely populated regions. This puts immense pressure on its public health system, especially due to unplanned urbanization. In addition, 1.2M Rohingya refugees from neighboring Myanmar have particular health vulnerabilities. Bangladesh's healthcare system is not able to keep up with these population patterns.
