As the measles vaccine turns 50, Centers for Disease Control officials warn the fight against the disease isn't over.
FOX News Radio's Tonya J. Powers reports:
Measles was considered eliminated in the U.S. in 2000, but this year, there's been a spike in cases.
CDC Director Dr. Tom Freiden says global travel means a disease can be spread nearly anywhere in 24 hours.
(Dr. Freiden) "And as long as there is measles anywhere in the world, there is a threat of measles anywhere else in the world."
He says the keys to stopping the spread are getting the first vaccination early, making sure the second dose is given, and testing to identify how it's spreading.
