It's an 8,000-mile race into a hot zone, dressed in a head-to-toe protected suit. I travel with the lead team of disease hunters from the CDC, joining a hunt for one of the world's deadliest diseases. Movies such as Contagion have tried to capture the terror of continual virus. What we found is much more frightening. We make our way to the hospital, where Ebola patients are being treated. Here is a suit that in even more protective gear. 

Upsides off the gulp with proper something. That抯 it.

Every part of my body is covered, even a skin mask over my eyes. 

Without one speck of my body that it is exposed.

One careless mistake can be deadly.

I have to say that there抮e few things that I've done in medicine that as nerve wracking as going into this place. 

We enter.

Those are the three who have Ebola, over there, over there and over there.

Oh, yes.

We don't know how these patients got Ebola. But we do know that very close contact with body fluids can spread it. 

Anytime someone touches something, they quickly sprayed down with disinfectant. 

Thank you.

What makes Ebola so terrified in as low as two days,there can be fever, then these patients' organs can fail, uncontrollable internal bleeding can start. There was no treatment, more than half of those who get sick will die.  Looking at the patients, the care is basic at best and it is blisteringly hot. You can only stay in the suit for about 40 minutes. 

Doctors Without Borders with the efforts on the ground here to make treatment more effective, and the CDC just stop the spread and figure out what caused it. CDC's Barbara Kenust sees it as a critical mission here and across the globe.

We don't have high walls around our country. It just because something happens far away in Africa doesn't mean that it can抰 happen back in the United States.

The feeling I had in that world was absolutely frightening. That's not something we ever want to experience in America. That's why it's so important the CDC is there to help and to learn.
