WDSU news reports the Centers for Disease Control and Prevention says 5,412 measles infections have been reported across 45 states. The count rose by 230 since last Friday, and a decision on whether the United States keeps measles elimination status could come as soon as Friday.
Centers for Disease Control and Prevention count
The reported total is far above the United States average of 180 measles cases a year between 2000 and 2024. State health departments have reported eight deaths, including six in Pennsylvania, one in New York and one in Wisconsin.
That is the scale readers are dealing with now: a national outbreak count that has climbed well beyond the annual average, with cases spread across 45 states. The spread also means the numbers are not isolated to one region or one school year.
MMR vaccine gaps
The outbreak has unfolded alongside lower measles vaccination coverage in young children. The number of kindergartners vaccinated with the measles vaccine fell from 95% in 2019 to 92% in 2026, and roughly 300,000 kindergartners entered classrooms this year without being vaccinated.
Two MMR doses are 97% effective at preventing infection. The first dose is given between 12 and 15 months of age, and the second is given between 4 and 6 years of age. A sick individual can infect 90% of unvaccinated people they come into contact with, and the virus can live on surfaces and in the air for two hours after a sick person leaves the room.
What readers should know
The practical issue now is whether the United States will keep measles elimination status while the outbreak keeps spreading across 45 states. With the case count already at 5,412 and rising by 230 in one week, the next federal decision will turn on whether the country can stop sustained spread before that status is reconsidered.
