The University of California and California State University, both in Los Angeles, are quarantining hundreds of staff members and students over potential measles exposures, reports The Washington Post.
UCLA confirmed that a student with the measles visited two campus buildings for classes on April 2, 4 and 9. The university said more than 500 people were potentially exposed to the virus. UCLA is still waiting to receive medical records for 82 people who will be quarantined until they can establish proof of immunity.
Cal State LA issued quarantine orders to 127 staff members and 71 students after officials learned of a potential measles exposure incident at the campus library April 11.
The quarantine could last up to 21 days.
The CDC reported 695 measles cases nationwide as of April 24, which marks the highest annual total since U.S. health officials declared the disease eradicated in 2000.
