Hundreds of students, staff and faculty at two Los Angeles universities have been quarantined because they may have been exposed to measles, according to Los Angeles County health officials, the latest development in a resurgence of the highly contagious disease that was declared eliminated in 2000.
Officials at California State University at Los Angeles alerted its students and staff that the exposure may have occurred at a campus library on April 11 from 11 a.m. to 3 p.m. Those at the library during that time were asked to provide immunization records or be checked for immunity at the health center, the university said in a statement Thursday.
