跟进：CDC周度数据全美麻疹病例升至4410例 一周新增330例 宾州病例增至1222例

Atlanta——美国疾病控制与预防中心（CDC）10月16日发布的周度数据显示，截至10月15日，全美今年麻疹病例累计达4410例，较一周前的上次更新增加330例；今年以来与麻疹相关的住院人数为451人。

从年龄分布看，5至19岁的儿童与青少年是感染人数最多的群体，共1856例、占42%；20岁及以上成年人1787例、占41%。疫情最集中的宾夕法尼亚州，据该州卫生部门数据，截至10月14日今年累计报告1222例、225人住院；本月14日本站报道时该州数字为1136例，一周多以来继续上升。宾州方面报告了5例麻疹相关死亡；CDC另行确认2026年有2例与麻疹相关的死亡，但未公布所在州。两套数字口径不同：CDC上月起改用国家卫生统计中心的死亡数据统计麻疹相关死亡，不再直接采用各州卫生部门的报告，这一调整受到外界质疑。

CDC本周二表示，将向宾夕法尼亚州增派人员，支援当地的疫情调查。本月初，纽约州就麻疹疫情发布灾害紧急状态，是美国第一个采取这一步骤的州。

CDC Weekly Update: U.S. Measles Cases Reach 4,410, Up 330 in a Week; Pennsylvania Cases Rise to 1,222

Atlanta — The U.S. Centers for Disease Control and Prevention reported on Friday, October 16, that measles cases nationwide have reached 4,410 as of October 15, an increase of 330 from its previous weekly update, with 451 measles-related hospitalizations so far this year.

Children and teenagers aged 5 to 19 are the largest group affected, with 1,856 cases, or 42 percent, followed by adults aged 20 and older at 1,787 cases, or 41 percent. Pennsylvania, the state at the center of the outbreak, has reported 1,222 cases this year as of October 14 and 225 hospitalizations, according to state health department data — up from the 1,136 cases reported when GSM last covered the state's figures on October 14. Pennsylvania has reported five measles-related deaths, while the CDC has separately confirmed two measles-associated deaths in 2026 without identifying the states involved. The two tallies rest on different methods: last month the CDC shifted to using National Center for Health Statistics mortality data for measles-related deaths rather than relying on state health departments, a change that has drawn scrutiny.

The CDC said on Tuesday that it would deploy additional support to Pennsylvania to help investigate the outbreak. Earlier this month, New York declared a disaster emergency over the measles outbreak, the first U.S. state to do so.
