ANAHEIM ( — Health officials Friday said a measles outbreak believed to have started in Southern California and went on to spark a national debate over vaccines and public health is now over.

The most recent diagnosed case was confirmed March 2, which led officials to designate April 17 as the date when the outbreak would be considered over if there were no new cases reported.

Of the California cases, 40 were traced back to visitors or workers at Disneyland between Dec. 17-20, according to health officials.

The outbreak renewed public debate over so-called “anti-vaxxers”, a term used to describe parents who opt out their kids from vaccination due to religious or philosophical reasons, or controversial fears that vaccines can lead to autism and developmental disorders.

At the height of the outbreak, several schools in the Southland – including Palm Desert High School and a Santa Monica daycare center – prohibited unvaccinated students from returning to class unless they could provide evidence that they had been vaccinated.
