State health officials say the number of measles cases is up in California this year and much of the increase is linked to overseas travel.
At UCLA, 119 students and eight staff members who were exposed to measles at the campus earlier this month and could not provide proof of immunity were ordered quarantined on Wednesday, the university said in a statement.
Students walk past the Harriet and Charles Luckman Fine Arts Complex at the The Cal State University, Los Angeles campus Thursday, April 25, 2019.
The LA campuses of the University of California and California State University imposed the quarantine after they became aware of people infected with measles who had potentially exposed hundreds. The student with measles attended classes at Franz Hall and Boelter Hall on April 2, 4 and 9 while contagious, according to UCLA. Some people may need to be quarantined for up to a week.
Nationwide, the government has counted almost 700 measles cases, roughly three-quarters of them in NY state, which had among the largest and longest-lasting outbreaks since the disease was all but eliminated in 2000. The UCLA quarantine will end by Tuesday, according to the Department of Public Health.
Hundreds of students and faculty at two universities in Los Angeles have been asked to stay home unless they can prove that they've been vaccinated against measles.
"Please be assured that we have the resources we need for prevention and treatment, and that we are working very closely with local public health officials on the matter", UCLA Chancellor Gene Block said in a statement.
A person with a confirmed measles case visited a public library at Cal State L.A. on April 11.
As a result, health officials requested that "Cal State LA employees" who may have been exposed "to provide immunization records or be checked for immunity" and refrain from going to work. At present, there is no risk of contracting measles at the library, CSU said in a statement.
Five cases of measles have recently been identified in Los Angeles County, health experts said.
The CDC says people in 22 states have the virus, six states have multiple cases; David Lee Miller reports.
She says more than 76% of patients were not vaccinated or didn't receive the recommended two doses of vaccine. Fourteen of those infected had travelled overseas to countries including Philippines, Thailand, India and Ukraine.
Measles is highly contagious and can stay in the air for up to two hours after a ill person coughs or sneezes, and can stay on surfaces for several hours, health officials say. However, a small fraction of those infected can suffer complications such as pneumonia and a risky swelling of the brain.
Although the disease was eliminated from the country in 2000, meaning the virus was no longer continually present year-round, outbreaks still happen via travelers coming from countries where measles is common, the US Centers for Disease Control and Prevention says.
Ninety percent of people who are not immunized will come down with the measles if they come into contact with an infected individual, Ferrer said.
