Disney parks are supposed to be the happiest places on Earth, but many tragedies have struck there. These are some of the worst things that ever happened at Disney parks!
In 2014, 133 cases of measles were traced back to Disneyland in California. The disease was once thought to have been eradicated in the United States, but the recent trend of people not getting the measles vaccine likely contributed to the outbreak. In fact, at least 57 of those people infected in the outbreak were found to not be vaccinated. This actually isn't the first time there was a measles outbreak at Disneyland. There were other outbreaks in 1982 and 2001, but involving many fewer cases. Lesson learned, if you're going to go a place with huge crowds of people, make sure you've had your shots!
