DALLAS –– The first person to be diagnosed with Ebola within the United States has died, Texas hospital officials have said.
Thomas Eric Duncan, 42, who caught the virus in his native Liberia, was being kept in isolation in a Dallas hospital and receiving experimental drugs.
Earlier the United States announced new screening measures at entry points to check travellers for symptoms of the virus.
It has killed 3,865 people, mostly in Liberia, Sierra Leone and Guinea, in the worst Ebola outbreak yet.
“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 a.m.,” a spokesman said in a statement.
The news came shortly after American Secretary of State John Kerry urged all nations to boost their response to combat the virus.
“More countries can and must step up,” he said in a joint press conference with his British counterpart Philip Hammond.
“Ebola is an urgent global crisis that demands an urgent global response.”
The United States has pledged as many as 4,000 troops to the region, while the UK is sending 750 military personnel to Sierra Leone.
Duncan, who worked as a driver for a courier company, tested positive in Dallas, Texas, on 30 September, 10 days after arriving on a flight from Monrovia via Brussels.
He became ill a few days after arriving in the US but after going to hospital and telling them he had been to Liberia he was sent home with antibiotics.
Four days later, he was placed in isolation but his condition continued to worsen and this week he was given an experimental drug.
Ten people he came into contact with are being monitored for symptoms.
Following Duncan’s diagnosis, the first case of contagion outside that continent was confirmed in Spain, where a nurse who treated an Ebola victim in Madrid contracted the virus herself.
Teresa Romero, is the first person known to have contracted the deadly virus outside West Africa.
She had treated two Spanish missionaries who later died from Ebola.
