In January, a measles outbreak at Disneyland caught the media’s attention. Over 114 cases appeared not only in California, but in six other U.S. states and parts of Mexico. Even though measles was officially eliminated from the United States in 2000, there have been more and more cases of the disease in the last seven years, with over 600 in 2014 alone. That year, one outbreak in an Amish community in Ohio included 383 diagnoses of measles. This particular religious community reconsidered its previous relaxed stance on vaccines. The Amish weren’t opposed to vaccination, but rather didn’t realize that measles was still such a threat to public health.
