Measles - California, USA

Dozens of people at two California universities have been quarantined as US health officials battle to stop the spread of a nationwide measles outbreak, authorities said Thursday. The Department of Public Health said hundreds of students and staff at the University of California Los Angeles (UCLA) and California State University (Cal State) had been exposed to a measles carrier earlier this month.

UCLA said an infected student had attended campus on three days earlier this month, coming into contact with about 500 people. Around 100 had been quarantined after they couldn't provide immunization records. Cal State said 156 students and staff who may have been exposed to an infected student were quarantined.

Worldwide, measles cases rose 300 percent through the first three months of 2019 compared with the same period last year, according to the United Nations.
