宾州麻疹病例达977例 成为30年来全美最大州级疫情
据路透社10月2日报道，宾夕法尼亚州卫生部门官网数据显示，截至10月2日该州今年已报告977例麻疹病例，疫情仍在快速蔓延，成为30多年来全美规模最大的州级麻疹疫情。
本周三，该州报告了今年第五例麻疹相关死亡病例，为一名未接种疫苗的兰开斯特县居民。今年宾州所有麻疹死亡病例均为未接种疫苗者。美国疾控中心（CDC）数据显示，截至10月1日全美今年已报告3887例麻疹病例，宾州仍是全美麻疹疫情的中心。
CDC 表示，正与各州流行病学家合作制定麻疹相关死亡的统一统计标准。值得注意的是，CDC 在全国层面今年仅确认了2例麻疹相关死亡、未点名具体州份，与宾州自行统计的5例存在口径差异，引发公共卫生界的讨论。
麻疹是传染性极强的病毒性疾病，但可通过麻疹-腮腺炎-风疹（MMR）疫苗预防，两剂接种后有效率达97%。宾州卫生部门已在疫情集中的乡村县增设疫苗接种点并派出流动接种车，呼吁尚未接种的居民尽快补种，特别是有儿童的家庭。
Pennsylvania Measles Cases Hit 977, Largest State Outbreak in 30 Years
Pennsylvania's health department reported 977 measles cases as of Friday, October 2, according to its website, as the state battles a fast-growing outbreak — the largest state-level measles outbreak in the U.S. in more than three decades, Reuters reported.
The state reported its fifth measles-associated death of the year on Wednesday — an unvaccinated Lancaster County resident. All five people who died of the disease in Pennsylvania this year were unvaccinated. CDC data shows 3,887 U.S. measles cases as of October 1, with Pennsylvania remaining the center of the nation's surge.
The CDC said it is working with state epidemiologists on a standard definition for measles-related deaths. Notably, the CDC has confirmed only two measles deaths nationally this year without naming states — a definitional gap with Pennsylvania's count of five that has stirred public-health debate.
Measles is highly contagious but preventable with the MMR vaccine, 97% effective after two doses. Pennsylvania health officials have added vaccination sites in hard-hit rural counties and deployed mobile clinics, urging unvaccinated residents — especially families with children — to get caught up.
