In 2015, there was a measles outbreak in the United States (and other countries) that began when someone who had the measles visited Disneyland in California. In 2016, the World Health Organization (WHO) declared that measles had been eliminated from the Americas (the entire land mass that stretches from Canada to Chile).
But now, measles is back because people are choosing not to vaccinate their children against a dangerous, and preventable, childhood disease. In this blog, I will present facts about measles and the MMR vaccine. This blog also contains a timeline of the measles cases and additional contextual information.
