Cascade County Confirms First Measles Case, Statewide Total Reaches 26
CASCADE COUNTY, MONTANA, JUL 16 – Montana reports 26 measles cases across six counties amid a national outbreak, with the first confirmed case in Cascade County isolating at home, officials said.
- On Tuesday, July 15, 2025, the City-County Health Department in Great Falls was notified of Cascade County’s first measles case, marking the first instance in over three decades.
- This month, the CDC reported the highest number of measles cases in the United States since the disease was declared eliminated in 2000.
- Health officers said the individual tested positive and is isolating at home, officials say the source of infection remains unknown, bringing Montana’s statewide total since April to 26 cases across six counties.
- Local authorities said the county website lists exposure sites including the Great Falls Walmart at 5320 10th Ave, specific locations remain under review, and CCHD is offering MMR vaccines to eligible residents.
- A 2025 legislative attempt to improve immunization data sharing failed, and Montana remains the only state not publicly sharing county-level immunization data, complicating outbreak response.
