As of Tuesday (November 3), Wisconsin has recorded a total of 431 measles cases statewide. Health officials, including the Wisconsin Department of Health Services (DHS) alongside local health departments in Grant, Lafayette, Iowa, and Vernon counties, continue to coordinate multi-jurisdictional investigations and response efforts. The interactive measles data dashboard maintained by DHS receives regular updates every Tuesday and Friday.
The largest concentration of infections remains centered in Southwest Wisconsin, where local transmission accounts for 362 confirmed and 6 probable cases across four primary counties: Grant County (142 confirmed), Lafayette County (115 confirmed or probable), Iowa County (97 confirmed), and Vernon County (14 confirmed). Nearby Richland County has also identified 1 confirmed case directly linked to this ongoing Southwest outbreak.
In Northern and central regions, cases have primarily stemmed from out-of-state travel rather than the Southwest cluster. Chippewa County has reported 44 confirmed cases, while Marathon County has documented 6 confirmed cases, with both locations having passed 21 days since the last rash onset. Recent travel-related additions as of November 3 include 2 confirmed cases in Marquette County, 1 probable case in Buffalo County, and 2 confirmed cases in Jackson County. Meanwhile, Rock County has logged 5 probable cases with an unidentified infection source, though over 21 days have elapsed since rash onset there as well.
To safeguard individual privacy, state and local public health agencies are withholding further personal health identifiers. Residents looking for additional details, resources, and live tracking can access the state case count dashboard at DHS Wisconsin's immunization page or visit their primary outbreak index.
