宾州麻疹疫情蔓延：累计报告943例、5人死亡
【哈里斯堡讯】10月1日，宾夕法尼亚州卫生部门通报，全州麻疹确诊病例累计已达 943 例，其中 5 人死亡。据路透社报道，这是近年来美国最严重的州级麻疹疫情之一，病例仍在持续增加。
卫生官员表示，多数病例集中在疫苗接种率偏低的社区，患者以未接种麻疹疫苗的儿童和青少年为主。州卫生厅已向疫情社区派出流动接种队，并在学校开学季加强入学疫苗记录核查。
专家指出，麻疹传染性极强，群体免疫门槛约为 95% 的接种覆盖率。宾州部分县的学龄儿童麻疹疫苗接种率已跌破这一水平。
州卫生厅呼吁家长尽快带孩子补种疫苗，并提醒出现发热、皮疹症状者及时就医并避免前往公共场所。

Pennsylvania Reports 943 Measles Cases, 5 Deaths as Outbreak Spreads
[HARRISBURG] Pennsylvania health officials reported October 1 that confirmed measles cases statewide have reached 943, with 5 deaths — one of the worst state-level measles outbreaks in the U.S. in recent years, Reuters reported, with case counts still rising.
Health officials said most cases are concentrated in communities with low vaccination rates, mainly among unvaccinated children and teenagers. The state health department has dispatched mobile vaccination teams to affected communities and tightened school immunization-record checks for the new school year.
Experts note measles is highly contagious, with herd immunity requiring about 95% vaccination coverage. In some Pennsylvania counties, school-age measles vaccination rates have fallen below that threshold.
The health department urged parents to get children vaccinated promptly and advised anyone with fever and rash symptoms to seek care and avoid public places.
