As of Thursday, Wisconsin reported 431 cases of measles, with all but three cases occurring in unvaccinated individuals.

The Centers for Disease Control and Prevention (CDC) has confirmed four measles-associated deaths in the U.S. This year.

The CDC estimates that 1 to 3 out of every 1,000 children with measles die from respiratory and neurological complications.

The DHS has delivered over 42,000 doses of MMR vaccine statewide since August 1, 2026, in an effort to curb the spread of the disease.

High vaccination rates had stopped the spread of measles in the United States in 2000, but cases are rising again as vaccination rates decline.

People who are unsure whether they are vaccinated against measles can contact their health provider or check the Wisconsin Immunization Registry at dhfswir.org.

Prior to last year, the most recent U.S. Measles death was in 2015.

In 1990 alone, the U.S. Recorded more than 27,000 cases and 89 measles-associated deaths, according to the CDC, which found that failure to vaccinate children on time was the main driver.
