ROANOKE, Va. -

A second American aid worker diagnosed with Ebola is in Atlanta tonight being treated for the deadly disease.

The woman was flown in from Africa where she contracted the disease.

Ebola is a highly contagious virus.

Nearly 900 people have died in an outbreak in west Africa.

We asked WDBJ7's Susan Bahorich to look into the disease and find out how the area's trauma center would handle a similar situation.

Dr. Thomas Kerkering is Chief of Carilion Roanoke Memorial's Infectious Diseases Department.

He tells us the Ebola Virus is spread by bodily fluids and it could be spread by kissing if one person had the disease, but he says there is no evidence that its ever spread from airborne contact like sneezing or coughing.

"Africa is a great place to go. I get rejuvenated every time I go there because life is treasured," explains Dr. Thomas Kerkering.

Dr. Kerkering knows first hand.

During his 40-plus years as a doctor, he's made dozens of trips to Africa.

As head of Carilion's Infectious Diseases Department, WDBJ7 asked him to talk about the Ebola Virus.

"It's a virus with a high mortality, so people die - 70-80%. And, when they die there are there different funeral rituals than we would have in the United States," says Dr. Kerkering.

Meaning when bodies are prepped in Africa, people are exposed to bodily fluids- like blood, vomit and waste.

That's how two American health care workers came into contact with the illness.

Now that those workers are back in the U-S many are worried -the public could be exposed to the disease - something Kerkering says is unlikely.

Says Kerkering, "Is it possible to get a case? It would be possible, is it probable- no."

And, while it's not likely, he says Roanoke Memorial would be prepared if a case should turn up in the region.

"We have all sort of procedures that we follow and there are certain infectious diseases that require for lack of a better term "quarantine" or we'll call it "isolation" or this type of protective equipment to be worn by the healthcare provider nursing staff and with Ebola we would have those same types of procedures," he says.

Kerkering says if there was a situation where the virus was found in this area, health care workers would have total body covering including goggles and face masks.

But, he points out things like body suits are a luxury- and not available in Africa.
