宾州麻疹累计1078例：多数新增为两周前旧病例补报，非新一波暴发
据ABC News 10月8日报道，宾夕法尼亚州卫生厅10月7日公布的每周通报新增74例麻疹，使该州2026年累计病例达到1,078例，涉及41个县。
州卫生官员强调，这74例中新报告的病例中，有40多例是约两周前的感染，只是近期才补录入系统，并不代表新一波传播。此轮疫情始于4月底。
兰开斯特县仍是震中，累计401例。疫情已导致207人住院、5人死亡：两名未接种疫苗的成人（18岁和40岁）、两名不足接种年龄的婴儿，以及一名兰开斯特县未接种疫苗的居民。
据卫生厅介绍，全程接种疫苗者中的病例不到1%，约三分之一的病例为18岁以下人群。卫生官员继续敦促居民核查接种情况，指出两剂MMR疫苗预防麻疹的有效率约为97%。
宾州疫情加剧之际，全美正面临30多年来最严重的麻疹年份，2026年全美累计报告约4,080例。
Pennsylvania Measles Cases Reach 1,078, With Most New Reports From Weeks-Old Infections
Pennsylvania added 74 new measles cases in its weekly update released October 7, bringing the state's 2026 total to 1,078 cases across 41 counties, ABC News reported on October 8.
State health officials emphasized that more than 40 of the 74 newly reported cases were infections from about two weeks ago that were only just entered into the system — they do not represent a new wave of transmission. The outbreak began in late April.
Lancaster County remains the epicenter, with 401 cases. The outbreak has resulted in 207 hospitalizations and five deaths: two unvaccinated adults, ages 18 and 40; two infants too young to be vaccinated; and an unvaccinated Lancaster County resident.
According to the health department, fewer than 1% of cases occurred in fully vaccinated individuals, and about one-third of cases are in people under 18. Health officials continue to urge residents to check their vaccination status, noting that two doses of the MMR vaccine are about 97% effective at preventing measles.
The surge comes as the U.S. faces its worst measles year in more than three decades, with roughly 4,080 cases reported nationally in 2026.
