宾夕法尼亚州麻疹疫情确诊病例突破1000例，创美国消除该病以来新高

宾夕法尼亚州2026年麻疹疫情已确诊1,078例，其中1,066例发生于4月以来的当前疫情1。这是美国自2000年宣布消除麻疹以来规模最大的疫情，也是该州自1991年以来最严重的麻疹暴发1。过去七天内新增145例患者1。

疫情已造成严重的健康后果。截至最新统计，共有207人因麻疹住院1，其中5人死亡1。死亡患者年龄分别为新生儿、6周大婴儿、18岁、20岁和40岁，所有死者均未接种过麻疹疫苗1。其中两名年龄最小的死者由于年纪过小无法接种1。

Pennsylvania is experiencing its worst measles outbreak in decades, with confirmed cases reaching 1,078, marking the largest outbreak in the state since 1991 and the most significant in the United States since measles was declared eliminated in 20001. Of these cases, 1,066 have occurred during the current outbreak that began in April1. The outbreak has spread across multiple states, driven by the disease's high transmissibility2.

The outbreak has resulted in severe health consequences, with 207 hospitalizations and 5 deaths reported1. The deceased include individuals aged as young as a newborn and 6 weeks old, along with patients aged 18, 20, and 40 years1. All fatalities have been unvaccinated, including the two infants who were too young to receive vaccination1. In the past seven days, 145 new cases were confirmed1.

Medical professionals have warned that the actual severity of the situation exceeds public perception2, as the highly contagious nature of measles continues to fuel transmission throughout affected communities.
