(The Center Square) – Wisconsin’s measles outbreak continues to grow.
The state’s Department of Health Services updated its measles count recently.
“As of September 25, 2026, the Wisconsin Department of Health Services has confirmed 192 cases of measles in Wisconsin so far in 2026,” DHS said in a statement.
Most of Wisconsin’s measles cases remain centered in the southwestern corner of the state.
“There have been 180 confirmed and six probable cases in the outbreak in Grant, Iowa, Lafayette, and Vernon Counties,” DHS said in a statement. “The ongoing investigation indicates that measles is spreading locally. DHS, in coordination with Grant, Iowa, Lafayette, and Vernon County Health Departments, are working to identify and notify people who may have been exposed to the measles virus.”
But DHS has also confirmed measles cases in Marathon County and Chippewa County. The state said those cases are all tied to out-of-state travel, but they are not saying where the people traveled to or from.
Not everyone who has been confirmed to have the measles has been sick, however.
“Not everyone gets tested, needs medical care, or contacts public health agencies,” DHS explained. “Public health agencies continue to monitor reports of illness, conduct enhanced surveillance in outbreak areas, and work closely with health care and community health partners. Additionally, public health agencies continue working to help people protect themselves and prevent additional measles cases by providing access to vaccines and monitoring for any potential public exposures to measles.”
DHS’s best advice, the agency said, is for people to get vaccinated against the measles. DHS said one in four people who will test positive for the measles is unvaccinated.
The CDC last week said it has confirmed 3,659 measles cases in 47 state states or jurisdictions across the county.
The CDC said there have been 40 new measles outbreaks this year. But no one either in Washington, D.C. or Madison is saying where the outbreaks are coming from, or who has gotten sick.
