俄亥俄麻疹疫情再扩散 一周新增22例 全州病例较去年激增四倍
俄亥俄州的麻疹疫情仍在扩散。据《哥伦布快报》（The Columbus Dispatch）10月8日报道，俄亥俄州卫生部数据显示，全州过去一周新增22例麻疹病例，较前一周的10例新增激增120%，疫情已蔓延至又一个县。这是俄亥俄州2026年暴发的第三轮麻疹疫情，全州病例数较2025年同期上升了约400%。
麻疹是传染性最强的疾病之一，病毒可经空气传播，感染者在无防护环境下平均可传染十余人。卫生官员表示，疫情扩散与部分社区疫苗接种率不足密切相关：麻疹-腮腺炎-风疹（MMR）疫苗两剂接种率低于95%的社区，一旦出现输入病例便极易形成本地传播链。州卫生部门正与各县卫生机构合作追踪密切接触者，并呼吁家长核对儿童的接种记录，未接种者尽快补种。
放眼全美，麻疹反弹已成多州共同难题：邻近的宾夕法尼亚州卫生部门本周三通报新增74例，全年累计已达1078例，至少207人住院、5人死亡。俄亥俄州卫生部门提醒，出现高烧、咳嗽、流涕、红眼及皮疹等症状者应先电话联系医疗机构再前往就诊，以避免在候诊区传染他人。哥伦布所在的富兰克林县卫生部门也已加强监测，提醒居民留意官方发布的暴露地点通报。
Ohio Measles Outbreak Grows Again: 22 New Cases in a Week, Up 400% From 2025
Ohio's measles outbreak is still growing. The Columbus Dispatch reported on October 8 that the Ohio Department of Health recorded 22 new cases in the past week — a 120% increase from the 10 new cases reported the week before — and that the virus has spread to another county. The state is now in its third measles outbreak of 2026, with total cases running about 400% above 2025 levels. Measles is among the most contagious diseases known, spreading through the air and capable of infecting more than a dozen unprotected people from a single case. Health officials link the spread to pockets of low vaccination coverage: communities where two-dose MMR vaccination falls below 95% are vulnerable to sustained local transmission once the virus is introduced. State and county health departments are tracing contacts and urging parents to check children's immunization records.
Ohio's experience mirrors a multi-state resurgence. Neighboring Pennsylvania reported 74 new cases this week, bringing its 2026 total to 1,078 cases with at least 207 hospitalizations and five deaths. Ohio officials advise anyone with fever, cough, runny nose, red eyes and rash to call ahead before visiting a clinic, to avoid exposing others in waiting rooms.
