Hundreds of students and faculty at two universities in Los Angeles were asked to stay home unless they could prove they were vaccinated against measles.
Los Angeles campus campuses at the University of California and California State University have quarantined after they became aware of people infected with measles that potentially exposed the hundreds. At UCLA, a pupil exhibited at least 500 people earlier this month; in Cal State, someone with measles went to the library and met hundreds.
UCLA was notified by the District Public Health Department in Los Angeles that one of his students had chickenpox. After the identification of humans, the infected student could have come into contact while infected, the school asked for proof of immunization. On Wednesday, 119 people who could not provide evidence were quarantined.
Of these, dozens were able to prove immunity and were quarantined until Thursday afternoon. But 82 were still quarantined and "a few may need to quarantine for up to seven days," the school's statement said.
"Given the time that has passed since the last possible exposure of the individual to measles on April 9, the highest period of risk of developing measles has already passed – and the period in which symptoms may occur is close to the end," said Cancellor Jen The UCLA block said.
At Cal State, 156 library employees, some of them, were quarantined after they could not submit their immunization documents, the Associated Press reported.
The Los Angeles County District announced on Monday that the county is experiencing measles, with international trips leading to five confirmed cases of measles, including students from Los Angeles and California Los Angeles. So far this year, 38 people have been infected with measles in California, state authorities said, according to the Los Angeles Times.
From Wednesday, the Centers for Disease Control and Prevention reported 695 measles cases from 22 countries – the highest in the brain that was reportedly eliminated from the country in 2000. There was an increase of 300% in cases of measles in the world during the first three months of 2018, according to the World Health Organization. "That increase is part of the global trend seen over the past few years, while other countries are struggling to reduce vaccination rates and can aggravate the situation here," said the CDC.
