In a 2013 Brooklyn outbreak, an unvaccinated 17-year-old was infected in London and returned home, causing almost 60 infections in an Orthodox Jewish community.
An Ohio outbreak in 2014 infected 382 people, many in an Amish community, where vaccinations are discouraged. Nine were hospitalized.
Disease experts say the outbreak likely started when a traveler with measles came into contact with unvaccinated people who then infected each other. While in California, the overall vaccination rate is 90.7 percent, some school districts in Orange County and surrounding areas have rates below 90 percent, making them more vulnerable to infection.
Colorado and Ohio are the states with the lowest vaccination rates among children, each at 86 percent as of 2013.
In some areas, rates of vaccination are even lower—as many as a quarter of children in one Northern California town were under-vaccinated, putting not just other children but the entire community at risk.
Rates are as of 2013.
