A Liberian, Thomas Duncan who was the first person to be diagnosed with Ebola within the US has died, Texas hospital officials have said.
According to reports, Duncan died at the isolation ward of a Dallas hospital.
Earlier the US announced new security procedures at entry points to check travellers for symptoms of the virus.
More than 3,000 people have died in West Africa in the worst Ebola outbreak yet.
While Duncan was the first person to be diagnosed within the US, three American aid workers and a photojournalist contracted the virus in Liberia.
“It is with profound sadness and heartfelt disappointment that we must inform you of the death of Thomas Eric Duncan this morning at 7:51 am,” a spokesman said in a statement.
