Outbreak of Measles in Oconto County, Wisconsin Traced to Single Out-of-State Travel Event

According to the Centre for Disease Control and Prevention (CDC), as of this week, over 1,300 cases of measles have been reported in the U.S. this year. In a more local context, Oconto County in Wisconsin has been affected, with nine confirmed cases of measles.

Health officials in Oconto County believe the common source of measles exposure was a single exposure event during out-of-state travel. The exact location of this travel outside Wisconsin remains undisclosed due to privacy reasons.

The first case in Oconto County was confirmed through lab testing, and the remaining eight cases were identified based on exposure and symptoms. No public points of measles exposure have been identified within Oconto County.

Measles, a highly contagious disease, can be spread through the air. Despite this, health officials in Oconto County believe the risk to the community is low. They are continuing contact tracing and notifications to ensure the situation remains under control.

The Wisconsin Department of Health Services confirmed the first measles cases in the state in 2025. The Oconto County Public Health has been actively managing the outbreak, but no further details about this incident have been released by health officials.

It is important to note that measles is preventable with the MMR (Measles, Mumps, Rubella) vaccine. If you are unsure about your vaccination status or have concerns, it is recommended to consult with a healthcare provider.
