Massachusetts public health officials have confirmed the state's first case of the measles this year and say people who have not been immunized who visited the same locations as the infected person may be at risk.

The state Department of Public Health says the person from greater Boston was diagnosed with the highly contagious disease Sunday. They were diagnosed at a clinic in Wellesley.

In the week before the diagnosis, the person visited KKatie's Burger Bar in Plymouth on Tuesday; a Starbucks in Waltham and the Mass Pike rest stop in Framingham on Wednesday; a Staples and a Dunkin' Donuts in Waltham, a Whole Foods Market in Hyannis, and a Target in Braintree on Thursday.

Anyone who thinks they were exposed and begins to develop symptoms of measles should call their health care provider.
