Woman who worked as nurse in Sierra Leone being tested for Ebola in Australia

Health officials in Australia have confirmed a 57-year-old woman is being tested for Ebola after returning to the country from Sierra Leone.

The woman returned to Australia at the weekend, after working as a nurse in an Ebola hospital in the west African country.

Meanwhile, a nurse infected with the disease in Spain may have contracted it after touching her face with a contaminated glove. Teresa Romero is said to be in a stable condition in hospital in Madrid this morning.

The US says it is now bringing in Ebola screening at some of its airports, including JFK in New York.

Tom Frieden from the US Centre for Disease Control and Prevention said people should not panic.

"It's a virus that doesn't spread therough the air and that we do know how to control," he said. "We do know how to stop it by isolating patients, doing contact tracing and breaking the chains of transmission."

Thomas Eric Duncan

Meanwhile, the death of the first Ebola patient diagnosed in the United States has renewed questions about his medical care and whether his life could have been extended or saved if the Texas hospital where he first sought help had taken him in sooner.

Thomas Eric Duncan died in Dallas yesterday, a little more than a week after his illness exposed gaps in the US' defences against the disease and set off a scramble to track down anyone exposed to him.

Mr Duncan, who was 42 years old and from Liberia, had been kept in isolation since September 28 at Texas Health Presbyterian Hospital.

He had first arrived there with a fever days earlier and told the staff he had been in west Africa. Doctors initially sent him home and he returned after his condition worsened.

Dr Phil Smith, director of the biocontainment centre at the Nebraska Medical Centre, where an NBC freelance cameraman is being treated for Ebola, said getting early treatment was key to survival.

When a patient reaches the point of needing dialysis and respiratory help, as Mr Duncan did this week, there may be little doctors can do.

“At that point, any kind of intervention, whether it is an antiviral drug or convalescent plasma, is less likely to work,” said Dr Smith, an infectious disease specialist.

Mr Duncan carried the deadly virus with him from his home in Liberia, though he showed no symptoms when he left for the United States. He arrived in Dallas on September 20 and fell ill several days later.

Of the six Ebola patients treated so far in the US, Mr Duncan was the only one not cared for in one of the special hospital units set up to deal with highly dangerous germs. That is because health officials knew the others had Ebola at the time they decided where the patients should go, whereas Mr Duncan sought care at Texas Health Presbyterian hospital on his own.

Health officials have also said that any hospital with isolation capabilities can treat Ebola patients, but Mr Duncan’s death is sure to renew attention on the hospital’s response.

There is no way to know whether any specific treatment or step might have saved Mr Duncan’s life. At the time of his death, he was taking an experimental anti-viral drug.

He died “despite maximal interventions”, said Dr Tom Frieden, director of the Centres for Disease Control and Prevention. “The earlier someone is diagnosed, the more likely they will be to survive.”

Pastor George Mason of Wilshire Baptist Church in Dallas was present when county officials told Louise Troh, who Mr Duncan had been staying with, of his death.

“She expressed all the what-ifs”, including whether the initial delay in admitting Mr Duncan made a difference, Mr Mason said.

Others in Dallas are still being monitored as health officials try to contain the virus that has ravaged west Africa, with about 3,800 people reported dead. The disease can be spread only through direct contact with the bodily fluids of an already sick person.

Health officials have identified 10 people, including seven health workers, who had direct contact with Mr Duncan while he was contagious. Another 38 people may also have come into contact with him. The four people living in the Dallas apartment where he stayed were moved to another home and are in isolation.

Officials have said everyone who had potential contact with Mr Duncan was being monitored for 21 days, the maximum incubation period for the disease, which can cause vomiting, diarrhoea, bleeding and in later stages, damage to vital organs.

Meanwhile a sheriff’s deputy who went into the apartment where Mr Duncan had stayed was admitted to hospital “out of an abundance of caution” after falling ill.

Federal and state health officials say there is no indication the deputy had any direct contact with Mr Duncan.

Mr Duncan’s illness has stoked anxiety in some parts of Dallas. Several people in the neighbourhood where he fell ill said they had been sent home from work. Some community volunteers shunned a nearby after-school programme and the hospital acknowledged that some patients were staying away out of fear of Ebola.

Mr Duncan went to the emergency room of Texas Health Presbyterian in Dallas on September 25, but was sent home. By September 28, his condition had worsened and an ambulance took him back to the hospital.

His family visited the hospital earlier this week and got a glimpse of him using a camera system. But relatives said on Tuesday that they declined to view him again because the first time had been too upsetting.

“What we saw was very painful. It didn’t look good,” Mr Duncan’s nephew, Josephus Weeks, said.

The hospital has changed its explanation several times about when Mr Duncan arrived and what he said about his travel history. The hospital has said the staff did not initially suspect Ebola, even though Mr Duncan told them on his first visit that that he came from west Africa.

His body is to be cremated and his remains returned to the family. The Centres for Disease Control recommends that bodies of Ebola victims not be embalmed and instead suggests they be cremated or promptly buried in a hermetically-sealed coffin.
