WAUKESHA COUNTY, Wis. (CBS 58) -- The Wisconsin Department of Health Services (DHS) announced Monday, Jan. 26, it has confirmed one case of the measles in a Waukesha County resident. 

Waukesha County Public Health Officer Ben Jones says the resident is an adult and the public risk factor is low due to limited exposure. 

DHS says the case is related to international travel. 

"Every place that this person was, we were able to identify all the people that were exposed, and we contacted them directly," Jones said. 

DHS, along with Waukesha County Health and Human Services, is currently working to identify and notify people who may have come in contact with the virus. 

Jones says the county has contacted more than 100 people, and some have been told to quarantine for 7-21 days. 

"If you're vaccinated, you don't need to worry," Jones said. "I would encourage people to be able to find their vaccination records in these situations. We're asking people for that proof."

This is the first confirmed case of the measles in Wisconsin so far this year. ProHealth Care Dr. Sandra Amadon says the two MMR vaccines last a lifetime.

"If you've had two vaccines in childhood, those vaccines last," Jones said.
