The Centers for Disease Control and Prevention has warned U.S. parents of a large-scale measles outbreak among children, while President Barack Obama encouraged parents to vaccinate their kids.

Following an outbreak of the viral infection at Disneyland in California back in December, CDC Director Tom Frieden warned Sunday that the outbreak could grow to a larger scale.

"We are very concerned by the growing number of people who are susceptible to measles, and the possibility that we could have a large outbreak in this country as a result," Frieden said on CBS's "Face the Nation."

Frieden went on to say that he believes the U.S. is "likely to see more cases," adding that the CDC is taking "aggressive public health action" to isolate those who have been infected with the virus from those who are healthy to minimize its spread.

In an interview with NBC News, President Obama also encouraged parents to vaccinate their children. "You should get your kids vaccinated," the president said directly.

The president went on to say that the science debunking a link between vaccines and autism is "indisputable."

 "I understand that there are families that, in some cases, are concerned about the effect of vaccinations," Obama said. "The science is, you know, pretty indisputable."

There are now 102 cases of measles reported in 14 states since the outbreak started at Disneyland over the holiday school break, when children from multiple countries were in close contact with each other.
