孟加拉国登革热今年已致418人死亡：10月173人病亡成全年最致命月份
孟加拉国10月录得今年以来单月最高的登革热死亡数字，专家警告，这轮疫情在12月之前不太可能明显缓解。
据孟加拉国卫生部数据，截至10月30日，这轮疫情今年已造成418人死亡、超过13.3万人入院治疗；仅10月一个月就有173人病亡，超过9月的148人，成为2026年以来最致命的一个月。
疫情之外，孟加拉国还在应对全球最严重的麻疹疫情，该疫情已造成1200多人死亡，本已吃紧的医疗系统压力进一步加大。
医生表示，许多登革热患者是在出现严重并发症之后才入院。在首都 Dhaka 的国立 Shaheed Suhrawardy 医学院医院，当天新入院67人后，在院登革热患者达到279人。院长 Mirza Golam Sarwar 说：「我们收治的许多病人处于休克状态，血压有时低到测不出来，血氧也在下降。」
内科专家 ABM Abdullah 表示，重复感染以及诊断、治疗延误是重症与死亡增多的原因。他说：「以前得过登革热的人，再次感染时发展成重症的风险可能更高。」他呼吁民众清除蚊虫滋生地、一出现症状就及时就医。
卫生专家警告，四种登革热病毒血清型同时流行，正在抬高重症风险：感染过一种血清型的人之后可能感染另一种，出现并发症的可能性随之上升。孟加拉国尚未引入登革热疫苗，当局正考虑将其作为一项长期措施。
Jahangirnagar University 昆虫学家 Kabirul Bashar 表示，死亡数字不太可能继续以10月的速度上升，但传播很可能持续整个11月。他说：「可能会有一些缓解，但登革热在11月不太可能消失；任何下降都会很有限，明显好转在12月之前不太可能出现。」他说，早前降雨形成的滋生地仍在孵化蚊虫，降雨与湿度模式的变化——部分与气候变化有关——正在延长蚊虫繁殖季。据路透社报道。
Dengue Has Killed 418 People in Bangladesh This Year, With October the Deadliest Month
Bangladesh recorded its highest monthly dengue death toll of the year in October, with experts warning the outbreak is unlikely to ease significantly before December.
The outbreak has killed 418 people and led to more than 133,000 hospital admissions this year as of October 30, according to health ministry data. October alone accounted for 173 deaths, surpassing September's 148 and making it the deadliest month of 2026 so far.
The surge comes as Bangladesh is also battling the world's worst measles outbreak, which has killed more than 1,200 people, placing additional strain on an already stretched healthcare system.
Doctors said many dengue patients were only seeking hospital admission after developing severe complications. At the state-run Shaheed Suhrawardy Medical College and Hospital in Dhaka, 279 dengue patients were being treated after 67 new admissions in a single day, hospital director Mirza Golam Sarwar said. "We are getting many patients in shock. Their blood pressure is sometimes too low to measure, and their oxygen levels are dropping," he said.
Medicine specialist ABM Abdullah said repeat infections and delays in diagnosis and treatment were driving severe cases and deaths. "People who have had dengue before may face a greater risk of severe illness if they become infected again," he said, urging people to eliminate mosquito breeding sites and seek care as soon as symptoms appear.
Health experts warn that the circulation of all four dengue virus serotypes is increasing the risk of severe disease. Bangladesh has yet to introduce a dengue vaccine, although authorities are considering one as a longer-term measure.
Entomologist Kabirul Bashar of Jahangirnagar University said transmission would probably persist through November: "We may see some relief, but dengue is unlikely to disappear in November. Any decline is likely to be modest, with significant improvement unlikely before December," according to Reuters.
