The students went on an off-campus field trip with the infected student during winter break, which started Jan. 12. It is unclear whether the field trip was a campus-sponsored event.
Kushner said the infected student, who lives in Orange County, has recovered and appears to be doing well. She did not live on campus.
Kushner did not know how the student became infected with measles.
