Just as California’s record-setting
Fifteen Californians have come down with measles thus far this year, officials said. And nearly half had opted against childhood vaccination against the disease through the state's personal beliefs exemption.
"Unfortunately, we're off to a bad year in 2014," said state epidemiologist Dr. Gil Chavez, during a phone call with reporters. At the same time last year, there had been only two measles cases, he added.
The California Department of Public Health reported illnesses in six counties: five in Los Angeles County, three each in Orange and Riverside Counties, and four combined in the Bay Area's Alameda, Contra Costa and San Mateo counties. None of the cases have been fatal, but measles can be deadly -- and health authorities remain concerned that many more may have been exposed to the virus.
For every measles case, Chavez said, there may be dozens of people local health officials must track to assure the disease hasn't spread. Earlier this week, fears emerged that thousands of people might have been exposed to measles when a sick UC Berkeley student traveled on the

Fewer than 3% of California schoolchildren use the exemption, said Dr. Kathleen Harriman, of the public health department's immunization branch.
Chavez said he was particularly concerned about the patients who had intentionally avoided vaccines.
"A myth persists among many parents that the measles vaccine is dangerous," he said. "These illnesses continue to make a comeback because we have people who refuse to be vaccinated."
No one has died of measles in California this year, but the illness can be deadly in cases with complications, officials said. The public health department urged people who have not had measles or received two doses of the measles vaccine to get immunized before traveling outside of the Americas, where the disease is under control.
People who are unsure of their vaccination status should also get immunized before travel, Chavez said.
Also on Friday, the public health department updated its current flu death count to 278, adding 35 new cases since the previous week.
Week by week, the numbers of doctor visits and hospitalizations for flu, as well as deaths, are declining, Chavez said. But he warned that "we're never out of the woods."
"Things seem to be going favorably, but we know flu is unpredictable," he said.
