Measles cases are on the rise in the United States as a result of increasing numbers of unvaccinated people and travel to and from countries with measles. A December 2014 outbreak at Disneyland has gained national media attention, emphasizing the importance of vaccination for measles. As of January 21, the measles outbreak at Disneyland has sickened more than 50 people, including five park employees, in four states and Mexico. This measles outbreak also comes on the heels of a new study in the journal Pediatrics showing that underimmunized and unvaccinated people tend to cluster together.
Local health departments play an important role in raising awareness about the importance of vaccinations and educating the community about how measles can spread and the risks to vulnerable populations. For more about measles, visit http://www.cdc.gov/measles/.
