宾夕法尼亚州报告今年第五例麻疹相关死亡

宾夕法尼亚州已报告2026年第五例麻疹相关死亡病例13，死者为未接种疫苗的兰开斯特县居民13。该州麻疹疫情继续蔓延，累计确诊943例病例，涉及39个县1，其中176人住院治疗1。兰开斯特县是疫情中心，已报告381例病例和5例死亡中的3例3。前两例死亡者为无法接种疫苗的婴幼儿，包括新生儿和6周大的婴儿3。疫情始于4月下旬13。

当前美国正经历自1991年以来最严重的麻疹疫情年份2，全国麻疹总病例数超过3,600例1。宾州卫生部门已通过180个临时疫苗诊所开展MMR疫苗接种，超过5,500人接种1。MMR疫苗对麻疹的预防效率为97%1，已接种者中的确诊病例仅占总数不足1%1。

然而，由于特朗普政府改变了麻疹死亡报告方式，美国疾病控制中心未将宾州报告的死亡病例纳入全国统计1。宾州本月早些时候向疾病控制中心申请紧急援助，但警告称除非联邦机构公开承认该州报告的麻疹相关死亡，否则可能撤回请求1。美国卫生部长罗伯特·肯尼迪二世公开质疑这些死亡是否由病毒或其他病症引起1。

Pennsylvania has confirmed its fifth measles-related death in 2026, marking a continued escalation of the state's outbreak 13. The deceased was an unvaccinated resident of Lancaster County 13. The outbreak, which began in late April, has now spread across 39 counties with 943 confirmed cases and 176 hospitalizations 13. Lancaster County remains the epicenter, accounting for 381 cases and three of the five deaths 3.

The current outbreak represents the most severe measles year in the United States since 1991 2. Of the total infections in Pennsylvania, only four cases have occurred among vaccinated individuals—less than 1 percent of all cases 1. The MMR vaccine demonstrates 97 percent effectiveness against measles 1. In response, the state health department has administered over 5,500 MMR vaccinations through 180 temporary vaccine clinics 1.

The deaths have affected vulnerable populations. The first two fatalities involved infants who were too young to receive vaccination, including a newborn and a six-week-old infant 3. Despite the severity of the outbreak, the U.S. Centers for Disease Control and Prevention has not included Pennsylvania's reported deaths in national statistics, reportedly due to changes made by the Trump administration regarding how measles deaths are reported 1. Pennsylvania requested emergency federal assistance earlier this month but warned it may withdraw the request unless the CDC publicly acknowledges the state's reported measles-related deaths 1. Health and Human Services Secretary Robert F. Kennedy Jr. has publicly questioned whether the deaths were caused by the virus or other conditions 1.
