The annual recurrence of dengue in Bangladesh: A persistent threat

TL;DR

Dengue remains a recurring public health threat in Bangladesh, with high infection and fatality rates among young adults in major cities.

Contribution

The paper highlights the cyclical nature of dengue and proposes strategies to combat its spread in high-prevalence areas.

Findings

Dhaka, Chattogram, Khulna, and Barishal reported the highest dengue infection burden in 2023.

Temporary vector control measures are leading to mosquito resistance, complicating dengue management.

Young adults aged 21-30 years are most affected, with high fatality rates.

This letter explores the annual recurrence of dengue infections in Bangladesh, a persistent threat to public health and well-being. We examine the cyclical nature of dengue infection across different regions, focusing on densely populated cities such as Dhaka and Chittagong. We also highlighted the challenges during the dengue epidemic by describing potential strategies for combating the spread, highlighting the severe health impacts on public health in high-prevalence areas such as Chittagong, Khulna, and Barisal. Recognizing dengue’s wide-reaching impact on health and daily life, we brainstorm the possible long and short-term solutions to prevent perpetuated future outbreaks.
