Health officials have announced Wednesday there are 79 confirmed measles cases in the state of California, as federal authorities reported that the number of U.S. cases in 2014 more than tripled any total in recent years.
According to the California Department of Public Health’s website, 52 of those cases stem from an outbreak at Disneyland and California Adventure in December.
There are four confirmed measles cases in Riverside County, where the Desert Sands Unified School District told 60 students – who have either not been vaccinated for measles or are unable to provide proof – that they need to stay home from school, CNN reported.
CNN affiliate KESQ reported that one student at Palm Desert High School is suspected of having measles. The student has been cleared to return to school but health officials are still trying to determine if the student actually had measles.
For now, the other 60 students will need to study at their homes.
“They are going to be asked to stay home until the incubation period for contagion is complete,” a spokeswoman for the school district, Mary Perry, said of the students who were released. The earliest a student is able to return without proof of vaccination will be February 9, the station reported.
There are 16 measles cases linked to Disneyland outside of the state of California including seven in Arizona, three in Utah, two in Washington, one in Colorado, one in Oregon, one in Nebraska and one in Mexico.
Arizona officials said they have identified 1,000 contacts of the seven cases in their state and are asking anyone with that group to isolate themselves (staying home from work) for 21 days if he or she isn’t vaccinated.
The disease outbreak came to light when visitors reported coming down with measles after visiting the park from December 15 to December 20. At least five Disney employees were diagnosed with measles, Disneyland said.
