Bangladesh is currently grappling with a severe dengue outbreak, witnessing a concerning increase in the number of cases and deaths. Last year alone, the country reported a staggering 321,179 cases of dengue, leading to 1,705 deaths. This marks a significant rise compared to the previous year when there were 62,000 cases and 281 deaths. The impact on children has been particularly devastating, with at least 113 child fatalities recorded, the majority of whom were under the age of 10.

Young children are especially vulnerable to the virus due to their underdeveloped immune systems. They account for approximately 30% of all dengue cases in Bangladesh, and those under the age of five face a higher risk of developing severe symptoms, such as dehydration and shock.

The surge in cases has overwhelmed the healthcare system, resulting in overcrowded hospitals where patients often outnumber available beds. Experts describe this as the deadliest dengue outbreak ever witnessed in Bangladesh. Unfortunately, the situation shows no signs of improvement in the new year, as the outbreak continues to claim lives. In the current month alone, there have already been 756 reported cases and 10 deaths, compared to 424 cases and three deaths during the same period last year.

However, these official figures may not accurately represent the true scale of the outbreak. Many healthcare facilities in Bangladesh operate beyond the reporting framework, suggesting that the actual burden of dengue could be significantly higher than reported. This highlights the urgent need for a comprehensive and coordinated response to effectively tackle the outbreak.

Dengue cases have been on the rise globally, with Asia being the most affected region, accounting for 70% of all reported cases. The World Health Organization (WHO) estimates that approximately 3.9 billion people, or half of the world’s population, are at risk of dengue infection. The number of reported cases has increased almost eight-fold from half a million in 2000 to 4.2 million in 2022.

The spread of dengue is exacerbated by the increasing frequency of extreme weather events, which facilitate its expansion to new locations and prolong dengue seasons in affected countries. In Bangladesh, unusually high rainfall, hotter temperatures, and high humidity have created favorable conditions for mosquito breeding. Experts emphasize that climate change plays a critical role in the surge of dengue cases.

Heartbreaking stories on the internet from affected families shed light on the devastating impact of dengue. Parents struggle to care for their young children who have contracted the virus. The lack of improvement in their children’s health after weeks of illness is distressing. Despite using repellents and mosquito sprays, mosquitoes still manage to infiltrate their homes due to factors such as open drains and overgrown yards in their neighbourhoods that provide ideal breeding grounds.

The recent outbreak has defied expectations by starting earlier than usual and spreading beyond its typical concentration in major cities like Dhaka and Chattogram. In 2023, 66% of reported cases occurred outside Dhaka, compared to 63% in the previous year. Dengue is now being reported in all 64 districts of the country, indicating the need for a widespread response.

To address this crisis, authorities have repurposed select hospitals originally designated for COVID-19 patients to manage the dengue epidemic. Efforts have also been made to increase the supply of essential medications across the country. However, experts stress that comprehensive mosquito control measures and prevention strategies are crucial to effectively curb large-scale outbreaks.

Healthcare infrastructure, particularly at the sub-district level, requires significant investment to strengthen Bangladesh’s response to dengue. Additionally, given that no effective vaccine has been developed for all four variants of the dengue virus, controlling the spread of the virus remains paramount. Innovative approaches such as releasing Aedes mosquitoes infected with bacteria that prevent their eggs from hatching show promise. Implementing integrated vector management strategies nationwide and exploring alternative solutions like Wolbachia-infected Aedes mosquitoes could be crucial in combating the disease effectively.

As Bangladesh continues its battle against this unprecedented dengue outbreak, concerted efforts are required to control mosquito populations, strengthen healthcare infrastructure, and develop effective prevention strategies. The country’s ability to protect its population from the devastating consequences of dengue will depend
