孟加拉登革熱死亡人數上升，12月前恐難緩解

達卡，10月31日（路透社）——孟加拉10月通報今年以來單月最高登革熱死亡人數，專家警告，這波疫情在12月前不太可能明顯緩解。DHAKA, Oct 31 (Reuters) - 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.

根據衛生部資料，截至10月30日，這波疫情今年已造成418人死亡，超過13萬3000人住院。光是10月就有173人死亡，超過9月的148人，成為2026年迄今死亡人數最多的月份。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.

病例激增之際，孟加拉也正與全球最嚴重的麻疹疫情搏鬥；麻疹已造成逾1200人死亡，使原本已吃緊的醫療體系承受更多壓力。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.

醫院承受壓力HOSPITALS UNDER PRESSURE

醫師表示，許多登革熱患者都是在出現嚴重併發症後才到醫院住院。達卡國營沙希德・蘇拉瓦迪醫學院暨醫院院長米爾扎・戈拉姆・薩瓦爾表示，該院在單日新增67名住院患者後，共有279名登革熱患者正在接受治療。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.

他說：「我們接收許多休克的患者。他們的血壓有時低到量不到，血氧濃度也在下降。」"We are getting many patients in shock. Their blood pressure is sometimes too low to measure, and their oxygen levels are dropping," he said.

內科專科醫師ABM阿卜杜拉表示，重複感染以及診斷和治療延誤，正導致重症與死亡病例增加。Medicine specialist ABM Abdullah said repeat infections and delays in diagnosis and treatment were driving severe cases and deaths.

他說：「曾經感染登革熱的人，如果再次感染，可能面臨更高的重症風險。」他並呼籲民眾清除蚊蟲孳生源，一出現症狀就盡快就醫。"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.

33歲達卡居民費薩爾・費爾杜斯曾在2017年、2024年以及本月稍早被診斷感染登革熱。正在家中休養的費爾杜斯說：「這一次，我和太太都需要住院治療。」Dhaka resident Faisal Ferdous, 33, was diagnosed with dengue in 2017, 2024 and again earlier this month. "This time, both my wife and I needed hospital treatment," said Ferdous, who is now at home recovering.

費爾杜斯表示，夫妻倆是在醫院待了數日後不久發病；當時他們5歲的兒子因另一種疾病在該院接受治療。Ferdous said the couple fell ill shortly after spending several days at a hospital where their five-year-old son was being treated for an unrelated illness.

他說：「每一次發病都很辛苦，而在反覆感染之後，你會越來越擔心重症風險。」"Every bout has been difficult, and after getting it repeatedly, you become increasingly concerned about the risk of severe illness," he said.

衛生專家警告，4種登革病毒血清型都在流行，正提高重症風險。感染其中一種株別的人，之後仍可能感染另一種，進而提高併發症發生機率。孟加拉尚未引進登革熱疫苗，不過當局正考慮將其作為較長期的措施。Health experts warn that the circulation of all four dengue virus serotypes is increasing the risk of severe disease. People infected with one strain can later contract another, raising the likelihood of complications. Bangladesh has yet to introduce a dengue vaccine, although authorities are considering one as a longer-term measure.

氣候變遷延長登革熱季節CLIMATE CHANGE EXTENDS DENGUE SEASON

賈漢吉爾納加爾大學昆蟲學家卡比魯爾・巴沙爾表示，死亡人數不太可能繼續以10月的速度上升，但傳播很可能持續到11月。Entomologist Kabirul Bashar of Jahangirnagar University said deaths were unlikely to continue rising at October's pace, but transmission would probably persist through November.

他說：「我們可能會看到一些緩解，但登革熱不太可能在11月消失。即使下降，幅度也可能有限；12月前不太可能出現明顯改善。」"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," he said.

巴沙爾表示，蚊子會持續從先前降雨形成的孳生地羽化，即使天氣轉乾，傳播仍會延續。他說，降雨與濕度型態的變化部分與氣候變遷有關，正延長蚊子孳生季節，並讓埃及斑蚊活動時間更久。Bashar said mosquitoes would continue emerging from breeding sites created by earlier rainfall, sustaining transmission even as conditions become drier. Changing rainfall and humidity patterns, partly linked to climate change, were extending mosquito breeding seasons and keeping Aedes mosquitoes active for longer, he said.
