明尼苏达州卫生署（MDH）上周晚些时候宣布，该州麻疹暴发事件从4月份开始，7月13日报道了最后一个病例。
本次暴发总共诊断了79人，大多数为未接种疫苗的儿童，成为近年来全国最糟糕的一次。明尼苏达州的此次暴发是自1990年以来最大规模的麻疹暴发，当时有460人感染病毒，3人死亡。
79例中有73例为10岁以下儿童，71例未接种疫苗。MDH估计有8000人暴露于病毒。共有22人住院，但此次暴发没有造成人员死亡。
在Hennepin县报告了大部分的病例（70例），那里是一个大型的明尼阿波利斯附近的索马里裔移民社区。由于担心麻疹，腮腺炎和风疹（MMR）疫苗导致自闭症，该社区疫苗的未接种率很高。根据MDH统计，79例中有64例出现在索马里，暴发开始时明尼苏达州索马里2岁儿童MMR疫苗接种率约为42％。
经过42天（2个21天的潜伏期）没有新的病例报告，暴发宣布结束。

Measles outbreak in Minnesota declared over
The Minnesota Department of Health (MDH) late last week declared the end of the state's measles outbreak, which began in April. The last case was reported on Jul 13.
A total of 79 people, mostly unvaccinated children, were eventually diagnosed during the outbreak, making it one of the nation's worst in recent years. It was Minnesota's largest since 1990, when 460 people were infected with the virus, and 3 people died.
Seventy-three of the 79 cases were in children under 10, and 71 were unvaccinated. MDH estimates that 8,000 people were exposed to the virus. A total of 22 people were hospitalized, but there were no deaths during the outbreak.
The vast majority of cases (70) were reported in Hennepin County, where a large Minneapolis Somali-American community lives. That community has high rates of vaccine hesitancy and avoidance due to unfounded fears that the measles, mumps, and rubella (MMR) vaccine causes Autism. According to the MDH, 64 of the 79 cases occurred in Somalis, and the vaccination rate for the MMR vaccine at the start of the outbreak was about 42% among Somali Minnesotan 2-year-olds.
The outbreak was declared over after 42 days (two 21-day incubation periods) passed with no new cases reported.
