92 confirmed measles cases and 6 probable cases are now reported across Iowa, Grant and Lafayette counties, with Iowa County alone at 52 confirmed infections.
17 new Iowa County cases since Tuesday helped drive the latest rise, while Lafayette County reported 37 confirmed and 6 probable cases and Grant County 3 confirmed cases.
Wisconsin health officials urged residents to check vaccination records, contact health providers and get the MMR shot if unvaccinated to slow further spread.
DHS said the MMR vaccine has been used for more than 50 years, recommends two doses for children by age 4, and noted people born before 1957 are considered immune.
