Dengue Nightmare Grips Bangladesh: Over 1,000 Deaths in Worst Outbreak on Record
Bangladesh is currently grappling with its most severe dengue outbreak on record, with over 1,000 people succumbing to the mosquito-borne disease this year alone. This alarming death toll has been exacerbated by the growing impact of climate change on the prevalence of dengue, according to the Directorate General of Health Services. The number of confirmed cases has surged past 200,000, highlighting the magnitude of the crisis.
Dengue is a tropical disease characterized by high fevers, headaches, nausea, vomiting, muscle pain, and, in severe instances, fatal bleeding. It is endemic to regions with tropical climates, and its rapid spread in Bangladesh this year can be attributed to erratic rainfall and rising temperatures during the monsoon season, providing an ideal breeding environment for the Aedes mosquito, which transmits the virus.
The World Health Organization (WHO) has sounded the alarm on the accelerated spread of mosquito-borne diseases like dengue, chikungunya, yellow fever, and Zika due to climate change. Dengue cases in 2023 have far exceeded the previous highest total recorded in 2022 when 281 deaths were reported throughout the year.
What makes this outbreak even more heart-wrenching is the fact that among the victims are 112 children aged 15 and under, including infants. This underscores the indiscriminate nature of the disease's impact and the urgency of the situation.
Kabirul Bashar, a zoology professor at Jahangirnagar University in Dhaka, emphasizes that this is not an isolated problem in Bangladesh but a global issue, with many tropical and sub-tropical countries experiencing heightened dengue activity this year. He attributes this surge to global climate change, which is creating optimal conditions for the Aedes mosquito to thrive.
Bangladesh has been grappling with dengue since the 1960s, but the first outbreak of dengue hemorrhagic fever, a severe and often deadly form of the disease, was documented in 2000. Since then, Bangladesh has witnessed a worsening trend of dengue outbreaks, with most cases occurring during the monsoon season. However, in recent years, hospitals have also been admitting dengue patients during the winter months, further straining the healthcare system.
Patients with repeat dengue infections are at greater risk of complications, and doctors report treating patients with more severe symptoms, often when it's already too late to provide effective treatment.
The situation in Dhaka's major hospitals is dire, with dengue wards filled to capacity, and patients lying beneath mosquito nets, while family members anxiously watch over them. According to Bangladesh's Directorate General of Health Services, as of Sunday night, the death toll has reached 1,006 people, making this year's outbreak more devastating than all previous years combined since 2000.
This unprecedented dengue outbreak is not only a massive health crisis for Bangladesh but also a stark reminder of the far-reaching consequences of climate change on public health. Urgent measures are needed to combat both the immediate crisis and the underlying climate-related factors driving the spread of dengue in the region.
