WHO documentation confirms that Bangladesh had a large, nationwide measles outbreak in early 2026, not a small local cluster. In its 2026-04-23 Disease Outbreak News item, WHO said Bangladesh notified it on 2026-04-04 of sustained domestic transmission affecting 58 of 64 districts across all eight divisions. For 2026-03-15 to 2026-04-14, WHO reported 19,161 suspected cases, 166 measles-related deaths, and either 2,897 or 2,973 laboratory-confirmed cases depending on which part of the same WHO item is used. The majority of cases were in children under 5 years, and Dhaka carried the largest burden. Response measures included a measles-rubella vaccination campaign, rapid response teams, surveillance strengthening, vitamin A supplementation, and hospital preparedness. The current monitoring trigger appears to come from media framing in October 2026 that Bangladesh is facing an unusually severe outbreak with wider warning value. In this session, however, no retrievable media articles were successfully returned, so newer media figures and phrases such as "world's worst" could not be verified. The main gap is recency: the latest official source found here is from April 2026. What to watch now is whether Bangladesh has released newer national totals, whether transmission continued after the April campaign, whether cross-border exportations were detected, and whether the April data inconsistency on confirmed-case totals has been clarified.

The main drivers are measles' very efficient respiratory spread and the official description of wide geographic distribution across Bangladesh. Risk is moderated by the availability of vaccination and established response measures, but uncertainty remains because the newest official source retrieved is several months old and current media framing could not be independently verified here. Tier capped at low: the event is historical.

官方

世卫组织2026-04-23疾病暴发新闻称孟加拉国于2026-04-04通报世卫组织，报告麻疹病例全国性增加，由持续本土传播驱动。世卫组织报告传播覆盖所有八个行政区和64个区中的58个。2026-03-15至2026-04-14期间，世卫组织摘要给出19,161例疑似病例、2,897例实验室确诊病例和166例麻疹相关死亡；正文则给出相同的疑似病例和死亡数，但实验室确诊病例为2,973例，另有30例确诊麻疹相关死亡。大多数报告病例为5岁以下儿童，达卡负担最重。

媒体，未经核实

该暴发记录之所以开启，是因为当前报道称孟加拉国麻疹形势异常严重，可能具有国际警示价值。本次会话未成功检索到媒体文章，因此无法验证独立媒体的病例数或死亡数。

控制措施

孟加拉国于2026-03-30批准全国麻疹-风疹疫苗接种运动。2026-04-05在18个重点区的30个上阿济拉开展定向接种运动，2026-04-20启动全国接种运动。世卫组织还描述了启动区快速反应队伍、加快疫苗采购、加强常规免疫、医院准备、对疑似和确诊病例补充维生素A、加强隔离和感染预防措施，以及扩大监测、培训和每周情况报告。
