(CNN)Happiness isn't the only contagious thing at Disneyland in California.
There's a measles outbreak at Disneyland, and one of California's top public health officials recommended that children under 12 and people who've never had a measles vaccination stay away from the park while the outbreak continues
However, Dr. Gil Chavez, deputy director of the State Epidemiologist Center for Infectious Disease, said at a Wednesday press conference that Disneyland would be "perfectly safe" if you've been immunized.
When asked for a response to Chavez's recommendation, Suzi Brown of Disney media relations said, "We agree with Dr. Chavez's comments that it is safe to visit Disneyland if you have been vaccinated."
Forty-two of the state's 59 measles cases since December can be linked to initial exposure at Disneyland and the adjacent Disney California Adventure Park in Anaheim, California Department of Public Health officials said.
In addition, eight other cases from people living in Utah, Washington state, Oregon and New Mexico were linked to Disneyland, Chavez said.
Since Friday, the public health department had been saying the outbreak linked to Disney was over.
But on Wednesday, Kathleen Harriman, chief of the Vaccine Preventable Epidemiology Section for the state public health department, said the most recent case was diagnosed, in a park employee, on Sunday.
