In Berkeley, the second UC Berkeley student in two months has been diagnosed with measles.

And to make matters worse, the student may have exposed an unknown number of Bay Area residents to the highly contagious disease.

The student rode BART from Oakland to Berkeley late last month, then attended class before being quarantined on April 3rd.

The city health department is notifying classmates and others who may have been exposed to the disease.
