Hundreds of students and teachers at two universities in Los Angeles have been asked to stay home if they cannot prove that they have been vaccinated against measles.
The LA campuses at the University of California and California State University quarantined after becoming aware of people infected with measles who had been potentially exposed to hundreds. At UCLA, a student exposed at least 500 people earlier this month; at Cal State, someone with brass went to a library and encountered hundreds.
UCLA was reported by the LA County Department of Public Health that one of the students had contrasted measles. After identifying people, the infected student could have come into contact with the infection while the school asked them to provide evidence of immunization. On Wednesday, 119 people were unable to quarantine.
Of these, dozens were able to prove immunity and were released from quarantine on Thursday afternoon. But 82 were still quarantined, and "some may stay in quarantine for up to seven days," the school said in a statement. "Given the time that has elapsed since the last possible exposure to the individual with measles on April 9, the highest risk period for developing measles has already passed – and the period during which symptoms may occur is approaching the end," said UCLA Chancellor Gene Block. ] In Cal State, 156 library employees, some of them students, were quarantined after they could not provide their immunization records, The Associated Press reported.
On Monday, Los Angeles County declared the county faced with an abuse of measles, with international travel leading to five confirmed measles cases, including students from UCLA and Cal State LA So far this year, 38 people have been infected with measles in California, state officials say, according to the Los Angeles Times.
From Wednesday, Centers for Disease Control and Prevention reported 695 cases of measles from 22 states – the highest it has been since measles apparently "eliminated" from the country in 2000. There has been an increase of 300% in the number of measles cases worldwide over the first three months of 2018, according to the World Health Organization. "That increase is part of a global trend seen in recent years, as other countries are struggling with decreasing vaccination rates and can exacerbate the situation here," said the CDC.
