A US doctor infected with the Ebola virus has arrived in the state of Georgia for treatment.
Doctor Kent Brantly, who had been working for an aid group in Liberia, was brought back home on board a private plane fitted with a portable tent designed for transporting patients with highly infectious diseases.
He is being treated at a hospital in Atlanta and will be joined by a colleague also infected with the deadly virus.
The current outbreak is reported to be the largest since the disease first emerged in Africa nearly 40 years ago.
Health officials meeting in the Guinean capital Conakry said a regional response was needed to stop the virus, which spreads through direct contact with bodily fluids.
Ebola has claimed the lives of over 720 people this year in Guinea, Sierra Leone and Liberia.
