Overview
- The Wisconsin Department of Health Services reported two laboratory-confirmed measles cases in Iowa and Lafayette counties, bringing the state total for 2026 to four.
- Tests were performed at the Wisconsin State Laboratory of Hygiene and officials say the new cases are not linked to the February Madison cluster.
- State and local health teams are tracing contacts and notifying people who may have been exposed, and no public exposure locations have been identified so far.
- Measles is highly contagious, can linger in the air for up to two hours after an infected person leaves, and symptoms usually appear 10 to 21 days after exposure.
- Health officials urge people to check the Wisconsin Immunization Registry, get MMR vaccine if unprotected, call ahead before visiting clinics if symptomatic, and use 211 for help finding vaccination providers.
