When Cathy Carillo and her family went on a trip to Yosemite National Park, they didn't expect that it would turn into a life or death situation.
Carrillo was staying in a tent cabin at the park last summer and became ill with the deadly hantavirus as mice hid in between the tent panels.
She was in critical care at the hospital for three weeks and spent 10 days in rehab. She had to relearn how to walk and talk, and doctors did not know if she would make it.
She is now suing Yosemite National Park for more than $3 million in damages.

"It was very scary because when I first got out of there I couldn't move at all," she said. "I was actually like paralyzed."
Carrillo said she has $500,000 in medical bills and is still suffering, mainly from diminished lung capacity and low energy.
"The doctors actually said I was a miracle because they didn't think I was going to pull through," she said.
Mark Algorri, Carrillo's attorney, said Delaware North, which is in charge of maintaining the park's resorts, was negligent about the disease because there were reports of it since 2008.

"They've known about it, they did not warn about it, and they did not maintain this premise, the park, in a safe condition," he said.
Delaware North has since taken down the double-walled tent cabins and replaced them with single-walled ones, as the mice would hide in between the panels. They also set up 18,000 mouse traps since June and plugged holes to prevent them from entering indoor areas.
There are multiple signs around the park warning of the virus.
But those signs weren't around when Carrillo and her family vacationed there.
Algorri expects Carrillo to receive more than $3.2 million.
"The fact (the Delaware North Company) knew about it, really didn't warn about it," he said. "The Carrillos went up there, been up there, never knew this problem existed. It was really kept on the down low."
