A student who goes to college upstate has contracted New York State's third case of measles this year.

The Department of Health says the patient traveled on an Amtrak train, so members of the public may have been exposed. 

They say anyone who was traveling on Amtrak train #120 from Penn Station to Albany on January 25 and hasn't been vaccinated should go straight to the emergency room to prevent others from getting the disease.

Measles is highly contagious and can cause a rash, a high fever and respiratory symptoms.

If you've been vaccinated, you're not at risk.

The student goes to Bard College in Dutchess County, where health officials held a vaccination clinic on campus.
