宾夕法尼亚州面临三十年最大规模麻疹疫情

宾夕法尼亚州正经历三十年来最严重的麻疹疫情2。截至上周，该州已报告943例确诊病例，分布在39个县1，并造成至少5人死亡12。死者均未接种疫苗2，其中包括一名20岁的阿米什妇女，她同时患有白血病2。公共卫生官员正为疫情进一步扩散做准备。

疫情蔓延的风险因多个因素而加剧。许多县缺乏独立的卫生机构，难以有效应对1。同时，某些特定人群的疫苗接种率较低1，这与美国国内疫苗怀疑主义抬头的趋势相关联1。西宾夕法尼亚地区的学校等机构已在为疫情扩散做准备2。

Pennsylvania is facing its largest measles outbreak in three decades, with health officials bracing for further spread of the disease. As of last week, the state had reported 943 confirmed cases across 39 counties, resulting in at least five deaths among unvaccinated individuals 12. One of those who died was a 20-year-old Amish woman who also had leukemia 2.

Public health officials attribute the outbreak's severity and potential for continued expansion to several factors, including low vaccination rates in certain communities and structural challenges in disease control. Many counties lack independent health departments to coordinate response efforts 1, complicating containment measures. The outbreak reflects broader concerns about rising vaccine skepticism in the United States 1. In response to the threat, schools and other institutions in western Pennsylvania are implementing preparedness measures 2.
