DHS Confirms Case of Measles in Waukesha County

Health officials investigating, no known public exposures identified

The Wisconsin Department of Health Services (DHS) and Waukesha County Health and Human Services have confirmed one case of measles in a resident of Waukesha County, representing the first confirmed case of measles in Wisconsin this year. The case was confirmed through testing at the Wisconsin State Laboratory of Hygiene.

The case is related to international travel. Due to privacy concerns, no additional personal identifying or health information will be released by DHS. DHS and Waukesha County Health and Human Services are working to identify and notify people who may have been exposed to the measles virus. At this time, no public exposure locations have been identified.

With cases of measles continuing internationally and nationally, DHS encourages Wisconsinites to check their vaccination status to make sure they are protected from measles. People who are planning a winter vacation should look at measles activity in the location where they plan to travel, and be sure everyone they are traveling with is up to date on needed vaccines.
