Measles
Two-thirds of all cases this year have been in adolescents and children age 19 years and younger.
Ninety-two percent of all cases have been in people who are unvaccinated or have unknown vaccine status. Four percent each of cases have been in people with one or two doses of the measles, mumps, and rubella (MMR) vaccine.
So far there have been 211 hospitalizations in the United States this year for measles, or 12% of case-patients. Three deaths have been associated with measles.
Utah-Arizona outbreak tops 200 cases
The largest current outbreak is along the Utah-Arizona border. Late yesterday Arizona health officials said there were nine more cases, for 137 total. Of the 137 cases, 133 are in Mohave County, where the outbreak is centered in Colorado City.
Together Mohave County and Southwest County, Utah, have 201 cases.
Finally today, the Minnesota Star Tribune reported Minnesota now has one of the lowest MMR vaccination rates among incoming kindergartners, mostly due to nonmedical exemptions.
Only 86.5% of Minnesota kindergartners are fully vaccinated against measles, well below the 95% threshold required for herd immunity. The lowest MMR vaccination rate in the United States is in Idaho, with 78.5%, followed by Alaska, Wisconsin, then Minnesota.
Before the pandemic, Minnesota had 92.5% coverage. Minnesota has had 24 confirmed measles cases in 2025 so far, the highest number seen in two decades, the newspaper reported.
