US health officials say 2011 was the worst year for measles in 15 years. There were 222 cases of the disease reported.

Most of the cases were imported, either by visiting foreigners or by U.S. residents who picked up the virus overseas.

Health officials say outbreaks in the U.S. have been fueled by low vaccination rates in Europe and elsewhere.

There were no deaths in the U.S., but about a third of the people were hospitalized.

At least two-thirds of the Americans who got the measles hadn't been vaccinated.
