Pennsylvania's explosive measles outbreak is now the largest the US has seen since the highly infectious virus was declared eliminated in 2000. With well over 1,000 cases, it's the largest on record since 1991.
截至今天下午，宾夕法尼亚州卫生官员报告称，2026年全年累计麻疹病例达1,078例。其中包括1月和3月的12例，其余1,066例均发生在4月份当前疫情爆发之后。这一数字包括过去七天内记录的145例，以及自周一上次更新以来确诊的74例。卫生官员指出，今天新增的74例中有40例发生在两周多前，目前才刚刚被记录在案。
Pennsylvania's health officials reported 1,078 measles cases in all of 2026 as of this afternoon. That includes 12 cases in January and March, with the remaining 1,066 cases since April, when the current outbreak began. The tally includes 145 cases recorded in the last seven days and 74 identified since the previous update on Monday. Health officials noted that 40 of the 74 cases added today were from more than two weeks ago and are just now being recorded.
在这些病例中，已有207人住院治疗，5人死亡——包括一名新生儿、一名6周大的婴儿、一名18岁青年、一名20岁青年和一名40岁成年人。所有死亡病例均发生在本次疫情期间的未接种疫苗人群中；两名婴儿则因为年龄太小而无法接种疫苗。
