2 dead, over 170 potentially exposed in 'superbug' outbreak

Infectious disease doctors say overuse of antibiotics creates resistant bacteria like CRE, but the gut-wrenching outbreak in California is an exception.

"You are as safe as you've ever been to get a scope because people know this is a risk. So I would say we're at a much less risk now than we were previously," said Dr. Jason Newland, with infectious disease at Children's Mercy. "The attention will make people even better at what we do."
