Bangladesh is once again in the grip of a severe dengue and chikungunya crisis in 2025. Hospitals are overwhelmed, fever wards are full, and doctors are working tirelessly. Families live in fear of mosquito bites, while daily news reports chronicle rising infections and deaths. As of December 16, 2025, the Directorate General of Health Services (DGHS) has reported more than 100,000 confirmed dengue cases and 409 deaths. However, this figure represents only the tip of the iceberg, as it reflects data solely from hospitalized patients, specifically from 77 hospitals in Dhaka and reports from 64 civil surgeon offices. A substantial number of dengue patients are receiving treatment at home or in various small and large hospitals and clinics that are not included in the official count. This underscores the overwhelming pressure on the country’s health system. At the same time, the Institute of Epidemiology, Disease Control and Research (IEDCR) has recorded a resurgence of chikungunya, reporting 337 suspected cases, 153 of which were laboratory-confirmed in Dhaka between January and May 2025. Researchers estimate that the true number of chikungunya infections this year may be close to one hundred thousand. As chikungunya testing is available only in a limited number of major hospitals in Dhaka, many cases remain undiagnosed and unreported.
