The CDC says the United States has logged 5,412 measles infections and 10 deaths, and a decision on Measles Elimination Status could come as soon as Friday. The count spans 45 states, with seven deaths in Pennsylvania, one in New York, and two in Wisconsin.
That tally is far above the 180 cases the United States averaged each year from 2000 to 2024. It also comes after 230 more infections were added since the CDC update last Friday.
CDC Measles Elimination Status
Measles elimination status depends on whether the virus keeps spreading at a level that breaks the standard used to keep national elimination in place. The CDC’s latest numbers show the country well beyond the routine level that had held for years, and the new death toll adds another measure of strain.
Wisconsin and Pennsylvania reported additional measles deaths on Friday. Wisconsin health officials reported a second measles death in the state, while Pennsylvania health officials reported an additional death, bringing the nationwide total to 10.
45 States And 5,412 Infections
The CDC said 5,412 infections had been reported across 45 states. That means the outbreak is not confined to one region and gives the status review a wider national footprint than a single-state event.
The practical risk for families is most acute for people without protection. Two MMR doses are 97% effective at preventing infection, and the vaccine is given in two doses, first between 12 and 15 months of age and again between 4 and 6 years of age.
MMR Coverage And Risk
Vaccination coverage has also slipped. The number of kindergartners vaccinated with the measles vaccine dropped from 95% in 2019 to 92% in 2026, and roughly 300,000 kindergartners entered classrooms this year without being vaccinated.
Measles is the most contagious disease in the world. One sick person can infect 90% of unvaccinated people they come into contact with, and the virus can remain on surfaces and in the air for two hours after that person leaves a room.
For readers, the immediate step is simple: check that MMR protection is current before exposure risks grow. The next official decision on Measles Elimination Status could arrive Friday, and the CDC’s numbers suggest the country is already confronting a record that no longer looks contained.
