Getting to the bottom of one of the country's largest health crises won't be easy, but someone is taking the job. On Thursday, we learned Dr. Mary Guinan will lead the investigation into the spread of hepatitis in southern Nevada.

The UNLV dean was appointed acting State Health Officer. Marie Mortera tells us just how she plans to fix this problem.

Dr. Mary Guinan's resume is a trip around the world. She's helped eradicate small pox in India, was a member of the CDC's AIDS Task Force, among many more assignments.  

Now she's joining the front-lines of a new medical mission to investigate the spread of hepatitis tied to the Endoscopy Center of Southern Nevada.

"My job is keeping people healthy and I intend to carry it out," Dr. Guinan insists. And she has quite a job ahead of her. It begins with former patients. "To look at those who have been affected by this and make sure they have the appropriate access."

Step two is an in depth review over recent inspections at ambulatory clinics throughout the state, then get with other states which have dealt with this crisis before. "Find out what they've been doing, what measures they took and felt were effective in solving the problem," Dr. Guinana explains.

That includes regaining the public's trust in our health care. "But the first step is to look at these ambulatory care clinics and find out where the system failed and stop it." Dr. Guinana says by combining the experts at UNLV and those with the state, that can be done.

Dr. Guinana has sat in this seat before, from 1998 to 2002. Even though Thursday was her first official day on the job, she had her work laid out for her. It included a round of meetings with state and federal health agencies.
