Dengue remains a major public health concern in Bangladesh, with recurrent seasonal outbreaks that threaten life and stretch the health system’s capacity. The 2026 outbreak has followed an unusual trajectory: national figures ran below the 2025 pace through mid-August, before a sharp monsoon-driven surge from late August pushed the cumulative case count past last year’s comparable tally within weeks.
According to the Directorate General of Health Services (DGHS), from the beginning of the year to 13 September 2026, more than 51,000 dengue cases and 149 deaths have been recorded nationwide. The dengue situation has continued to deteriorate in recent days. Between 8 and 14 September 2026, more than 8,000 new dengue cases were reported, with 16 deaths recorded during this six-day period. In September 2026, more than 15,000 new dengue cases and 52 deaths have been reported up to 14 September. During the first 14 days of September, the country recorded an average of more than 1,200 hospital admissions per day, indicating a continued sharp increase in dengue transmission and the pressure on health facilities. August recorded 20,536 hospital admissions and 43 deaths — more than double the 9,206 admissions recorded in July 2026.
