Do you know anyone who’s ever had measles, mumps, or rubella? Those diseases have essentially been wiped out in the U.S. because of effective and widespread adoption of vaccines.
But that might be changing. Dr. Thomas Frieden, Director for the Centers for Disease Control and Prevention, said that last year, there were more than 600 measles cases in the U.S., and that was more than there have been for a long time. "This year, there were 100 in January alone," he said.
