"Last year was the worst year for measles in the U.S. in 15 years, health officials said Thursday.
There were 222 cases of measles, a large jump from the 60 or so seen in a typical year. Most of the cases last year were imported -- either by foreign visitors or by U.S. residents who picked up the virus overseas.
U.S. children have been getting vaccinated against the measles for about 50 years. But low vaccination rates in Europe and other places resulted in large outbreaks overseas last year.
So far this year, 27 U.S. cases have been reported and it's too early to gauge whether 2012 will be as bad as last year. But with large international events like the London Olympics coming up, health officials are urging everyone -- particularly international travelers -- to make sure they're fully vaccinated."
And so it begins...the collapse of what used to be near-universal anti-measles vaccination, resulting in re-importation of the virus to places where it had almost been eradicated.
