According to CNN, two Americans in Liberia boarded a specially equipped plane to return to the United States for treatment.

Dr. Kent Brantley and hygienist and missionary Nancy Writebol, both contracted the disease while treating patients there.

Emory University in Atlanta confirmed that at least one of them will be treated at Emory Hospital, in an area physically separate from other patients.

On Tuesday, a vial of an experimental treatment for Ebola from the U.S. arrived in Liberia.  However, there was only enough for one dose.  Dr. Brantley insisted that the dose be given to Writebol.

Brantley received a transfusion of blood from a teenage Ebola survivor in an effort to help him fight the disease.  Transfusions from those who have survived Ebola have been used as treatment before, but there is no guarantee that it works.

Both are described to be in 'serious, but grave' condition.

The word that two infected patients were being brought to the U.S. triggered concerns on social networks like Twitter, with many expressing outrage that the patients weren't being treated outside the U.S. Read more at CNN HERE and the UK Daily Mail HERE.

WASHINGTON (AP) — The White House says it's looking into options for bringing back two American missionaries sick with Ebola in Liberia.

It would be the first time the disease was brought into the U.S.

Samaritans Purse Dr. Kent Brantly and Nancy Writebol, a missionary with the aid group SIM (S-I-M), remain in isolation. SIM USA President Bruce Johnson says Writebol is receiving an experimental drug.

White House Press Secretary Josh Earnest said that while the U.S. government would facilitate any transfer to the U.S., private companies would be used to transport them.

Late Thursday afternoon, officials at Atlanta's Emory University Hospital said they expected one of the Americans to be transferred there "within the next several days." The hospital declined to identify which aid worker, citing privacy laws.

The hospital has a special isolation unit built in collaboration with the Centers for Disease Control. It is one of only four facilities of its kind in the United States.
