Emory Hospital will accept two patients infected with the Ebola virus as health officials are working to contain the world’s largest outbreak of the virus to date.

The hospital and university officials sent out several advisories over the last few days about the arrival of the patients. They are two American health care workers who contracted the deadly virus while caring for patients in Africa, according to CBS 46 in Atlanta.

The university says the patients will be treated in a special isolation unit that was developed in collaboration with the Centers for Disease Control, another Atlanta institution. The university says its isolation unit is one of only four in the country designed for this kind of care. The patients are being transported by air ambulance.

An Ebola outbreak in West Africa has killed more than 700 people, according to CBS 46, making it the deadliest in history. To read the full story, click here. Ebola is a highly lethal virus, according to the World Health Organization, with a death rate of up to 90 percent. WHO says the symptoms are, “Sudden onset of fever, intense weakness, muscle pain, headache and sore throat are typical signs and symptoms. This is followed by vomiting, diarrhea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding.”

Ebola is transmitted through direct contact with the blood or other secretions of infected patients. There is no cure for Ebola and no vaccine.

“Emory physicians and health care staff are prepared for the arrival of these patients and have put infection control measures in place to protect health care workers and other patients and hospital visitors,” the advisory from Emory says. “The patients are housed in a special isolation unit separate from other units and patients.”
