Bangladesh dengue outbreak accelerates with over 42,000 hospitalizations and 117 deaths

Bangladesh is facing an accelerating dengue outbreak in 2026, with over 42,000 hospitalizations and 117 deaths recorded by September. The surge has severely strained a healthcare system already struggling with a measles outbreak that has killed nearly 1,000 children. Cases have spread across all 64 districts, causing severe hospital bed shortages. Experts warn that weather conditions could extend transmission into October, with September hospitalizations potentially exceeding 30,000.
