University of California, Berkeley is stocked up on the measles vaccine for people on campus after a student tested positive for the highly contagious virus.

That student may have exposed thousands of Bay Area Rapid Transit riders as well.

The infected student rode BART between the Downtown Berkeley and El Cerrito del Norte stations February 4-7.

At first the student thought he had a simple cold, but lab tests revealed he had measles.

Health officials say he was not vaccinated and was probably infected while traveling in Asia.
