Measles was declared eliminated from the U.S. in 2000, but in recent years we have seen measles reappear primarily as a result of people bringing the virus to the U.S. from other countries. During the last decade, we have seen approximately 100 cases of measles per year in the U.S. However, in 2014, there were 644 cases reported, and already this year there have been over 100 cases. Many of this year’s cases are connected to a large, multi-state outbreak linked to an amusement park in California. To date, there has been one case in Michigan (an adult). With all the news stories about measles, it’s easy to be concerned, but knowing the facts can ease your mind.
