State health officials say they've confirmed the first case of measles in Massachusetts this year.
Authorities say the person infected with the highly contagious disease is a visiting student from western Europe.
More than 95 percent of students have been vaccinated against measles, making an outbreak unlikely, according to Dr. Monica Bharel, the state's public health commissioner.
However, public health officials are still urging caution and have released a list of possible exposure sites, which are below:
