根据美国疾病控制与预防中心（CDC）发布的数据，截至2026年，美国累计报告了5,182例确诊麻疹病例。
A total of 5,182 confirmed measles cases have been reported in the United States to date in 2026, according to data released by the Centers for Disease Control and Prevention (CDC).
这种具有高度传染性但可通过疫苗预防的疾病的确诊数字，是CDC自1991年以来报告的最高数字。五岁以下儿童占病例的18%，5至19岁儿童占病例的41%。总体而言，儿童和青少年约占确诊病例的59%。大多数病例（共4,993例）与疫情爆发有关。
The figure for the highly contagious but vaccine-preventable disease is the highest number reported by the CDC since 1991. Children below the age of five make up 18 percent of cases, while children between ages five and 19 account for 41 percent of cases. In total, children and teenagers account for about 59 percent of confirmed cases. The majority of cases, a total of 4,993, were outbreak-associated.
此次疫情爆发之际，美国幼儿园儿童的疫苗接种覆盖率已从2019-2020学年的95.2%下降至2025-2026学年的92.4%。
The outbreak comes as vaccination coverage among US kindergarteners has decreased from 95.2 percent during the 2019-2020 school year to 92.4 percent in the 2025-2026 school year.
截至2026年11月的确诊病例数，是2025年报告的2,289例确诊麻疹病例的两倍多。根据CDC数据，2026年有四人死于麻疹。
The number of confirmed cases by November 2026 is more than double the 2,289 confirmed measles cases reported in 2025. According to CDC data, four people have died due to measles in 2026.
然而，该机构的全国死亡人数低于州官员报告的麻疹相关死亡人数，特别是在受疫情冲击最严重的宾夕法尼亚州。
However, the agency’s national death toll is lower than the number of measles-related deaths reported by state officials, particularly in Pennsylvania, the state hardest hit by the outbreak.
宾夕法尼亚州卫生部报告称，今年该州已有六人死亡、1,487例病例。
Pennsylvania’s Department of Health reported six deaths and 1,487 cases this year.
联邦统计数字一直是宾夕法尼亚州州长乔什·夏皮罗与美国卫生部长小罗伯特·F·肯尼迪之间围绕麻疹死亡如何分类这一争议的焦点。
The federal count has been at the centre of a dispute between Pennsylvania Governor Josh Shapiro and US Health Secretary Robert F Kennedy Jr over how measles deaths are classified.
宾夕法尼亚州报告“麻疹相关”死亡的标准是：确诊麻疹患者在出现症状后30天内死亡，除非死亡是由无关事件导致。
Pennsylvania reports “measles-associated” deaths after a person with confirmed measles dies within 30 days of developing symptoms, unless the death resulted from an unrelated event.
8月，宾夕法尼亚州报告称两名未接种疫苗者死于麻疹。CDC最初将这两例死亡计入全国统计，但随后在肯尼迪——一位疫苗怀疑论者——质疑麻疹是否导致或促成了这些死亡后，将其从统计中移除。
In August, Pennsylvania reported that two unvaccinated people died of measles. The CDC initially included the deaths in its national tally but subsequently removed them after Kennedy, a vaccine sceptic, questioned whether measles had caused or contributed to the fatalities.
美国疾病控制与预防中心（CDC）表示，正与美国州和地方流行病学家委员会合作，制定麻疹死亡的标准化定义。
The CDC has said it is working with the US Council of State and Territorial Epidemiologists to establish a standardised definition for measles deaths.
传染病专家警告称，关于如何对死亡进行分类的争议，使CDC与长期以来追踪麻疹后果的做法产生了分歧。
Infectious disease experts warn that the dispute over how to classify the deaths puts the CDC at odds with a longstanding approach to tracking the consequences of measles.
流行病学家告诉半岛电视台，追踪“麻疹相关”死亡长期以来一直是世界卫生组织和CDC采用的标准。
Epidemiologists have told Al Jazeera that tracking “measles-associated” deaths has long been a standard used by the World Health Organization and the CDC.
美国在二十多年前宣布消灭了该病毒。麻疹病例在全球范围内也有所增加，特别是在对疫苗持怀疑态度的社区，或医疗资源获取存在缺口的地区。
The US declared the virus eliminated more than two decades ago. Measles cases have also increased globally, particularly in communities that are vaccine-sceptical or where there are gaps in healthcare access.
专家警告称，某一地理区域的疫苗接种率下降，可能让数千英里外的人群变得脆弱，这使得麻疹预防成为共同的全球责任。
Experts warn that declining vaccination rates in one geographic location can leave people thousands of miles away vulnerable, making measles prevention a shared global responsibility.
