在2026年，美國正面臨超過三十年來最嚴重的麻疹疫情，這對於公共衛生而言是一個令人憂心的轉變。
In 2026, the United States is facing its most significant measles outbreak in over three decades, marking a concerning shift for public health.
截至九月，美國疾病管制與預防中心（CDC）通報在45個州確診了3,294起病例，這已經超過了前一年的總數。
By September, the CDC reported 3,294 confirmed cases across 45 states, already surpassing the totals from the previous year.
這種死灰復燃主要歸因於疫苗接種覆蓋率的下降，因為兒童免疫接種率已跌破維持群體免疫所需的95%關鍵門檻。
This resurgence is largely attributed to a decline in vaccination coverage, as immunization rates for children have fallen below the critical 95% threshold required to maintain community immunity.
對疫苗的猶豫心態增加以及錯誤訊息的傳播助長了這波下降趨勢，使得這種高度傳染性病毒更易於傳播。
Rising vaccine hesitancy and the spread of misinformation have contributed to this decline, making it easier for the highly contagious virus to circulate.
麻疹透過呼吸道飛沫快速傳播，並能在空氣中停留數小時，對嬰兒及免疫功能低下者等脆弱族群構成嚴重威脅。
Measles spreads rapidly through respiratory droplets and can linger in the air for hours, posing a severe risk to vulnerable populations like infants and the immunocompromised.
由於這種地方性傳播已持續超過一年，美國目前正面臨失去長期以來所保持的「消除」該疾病地位的風險。
With persistent, endemic transmission occurring for over a year, the U.S. is currently at risk of losing its long-held status of having 'eliminated' the disease.
這種情況突顯了公共衛生成就的脆弱性，並強調了在相互連結的世界中，維持高疫苗接種率以預防可預防疾病捲土重來的重要性。
This situation highlights the fragility of public health achievements and underscores the importance of maintaining high vaccination levels to prevent the return of preventable diseases in an interconnected world.
