Wisconsin is reporting its first case of measles this year.
The Department of Health Services says an adult resident in Waukesha County contracted the virus, and it is related to international travel.
It’s unclear if the person was vaccinated against the measles.
Officials noted they are working to find anybody who may have been exposed, and have already contacted more than 100 people.
Residents have been encouraged to check their vaccination status using the online Wisconsin Immunization Registry.
