LOUISVILLE, Ky. (WDRB) -- Kentucky is now one of just four states that require physicians to receive special training to detect child abuse.

At a ceremony at Kosair Children's hospital, Ky. Gov. Steve Beshear signed House Bill 157 into law. Starting July 15, doctors will begin training to recognize abusive head trauma in children, also known as Shaken Baby Syndrome. The one-time, one-hour course includes new science not widely taught in medical schools.

"This is huge," said Dr. Melissa Currie, of the U of L School of Medicine. "As far as I'm concerned, this is one of the biggest accomplishments we could have made because it means all of the doctors who are laying eyes on children in our state, for all kinds of different reasons, will now be armed with the knowledge to be able to keep them safe by recognizing early warning signs of abuse."

According to the federal Dept. of Health and Human Services, Kentucky and Indiana rank among the worst states in the nation for the rates of child abuse and neglect.
