Dengue fever is spreading to more areas worldwide due to environmental changes and weak healthcare systems. At the same time, existing health problems in patients are making the disease much more dangerous.

由於環境變遷與醫療體系薄弱，登革熱正向全球更多地區傳播。與此同時，患者原有的健康問題使得該疾病變得更加危險。

The increase in dengue is caused by a combination of climate change, fast-growing cities, and poor monitoring systems. Data shows that reported cases have risen sharply from about 500,000 in 2000 to 14.6 million in 2024. Furthermore, because many people do not show symptoms, the actual number of infections is likely higher than reported. In parts of Africa and Latin America, the response is often disorganized because of limited budgets and changing government priorities.

登革熱的增加是由氣候變遷、城市快速發展以及監測系統不完善共同造成的。數據顯示，報告病例數已從 2000 年的大約 50 萬例急增至 2024 年的 1,460 萬例。此外，由於許多患者沒有症狀，實際感染人數可能高於報告數。在非洲和拉丁美洲的部分地區，由於預算有限且政府優先順序變動，應對措施往往缺乏組織。

Medical challenges are increased because dengue symptoms are very similar to other illnesses, such as malaria, which often leads to wrong diagnoses. Early detection is critical, as patients can deteriorate quickly if not treated in time. Additionally, chronic health conditions significantly increase the risk of severe dengue. Dr. Anil Vardani emphasized that patients with diabetes are 2.5 times more likely to develop dengue hemorrhagic fever, and this risk increases eightfold if they also have heart disease. Other conditions, such as high blood pressure, obesity, and kidney disease, also lead to higher rates of organ failure and death.

醫療挑戰隨之增加，是因為登革熱的症狀與瘧疾等其他疾病非常相似，經常導致誤診。早期檢測至關重要，因為患者若未及時治療，病情可能會迅速惡化。此外，慢性健康狀況會顯著增加罹患嚴重登革熱的風險。Dr. Anil Vardani 強調，糖尿病患者發展為登革出血熱的可能性是常人的 2.5 倍，若同時患有心臟病，此風險將增加 8 倍。其他狀況如高血壓、肥胖和腎臟病，也會導致更高的器官衰竭率和死亡率。

To fight these threats, organizations are focusing on using rapid diagnostic tests and improving the '7-1-7' framework for detecting outbreaks. For example, the SUPAAT project in Uganda uses a team-based approach involving community engagement. However, there is still a major problem: there is no specific antiviral medicine, and vaccines have limited use. Historically, funding for these diseases only arrives after a crisis occurs. Therefore, there is an urgent need for long-term international cooperation and better urban planning.

為了對抗這些威脅，相關組織正專注於使用快速診斷測試並改良用於偵測爆發的「7-1-7」框架。例如，烏干達的 SUPAAT 項目採用了涉及社區參與的團隊協作方法。然而，目前仍存在一個重大問題：缺乏專門的抗病毒藥物，且疫苗的使用範圍有限。從歷史上看，這類疾病的資金通常在危機發生後才會到位。因此，迫切需要長期的國際合作以及更好的都市計畫。

Dengue continues to be a serious global health threat with expanding danger zones and high risks for vulnerable people. This situation requires urgent investment in better testing and new medical treatments.

登革熱持續是一個嚴重的全球健康威脅，危險區域不斷擴大，弱勢族群面臨高風險。此情況需要緊急投資於更好的檢測和新的醫療治療方案。
