Missionary infected with Ebola heading to US

Omaha - A missionary who was infected with Ebola while serving in Liberia is being flown to a US hospital for treatment, doctors said Thursday.

Officials at the Nebraska Medical Centre in Omaha said Dr Rick Sacra, 51, is expected to arrive sometime on Friday.

Sacra will begin treatment in the hospital's special isolation unit, believed to be the largest in the US

Sacra served with North Carolina-based charity SIM. Its president, Bruce Johnson, said Sacra was receiving excellent care at a centre in Liberia, but that the Nebraska facility provides advanced monitoring equipment and a wider availability of treatment options.

Sacra, who's from the Boston area, opted to head to Liberia after hearing that two other missionaries were sick. He was infected by the virus that has killed about 1 900 people. He's the third American aid worker infected by the Ebola.

The first two — Dr Kent Brantly and Nancy Writebol — have recovered since being flown to Emory University Hospital in Atlanta for treatment.

Possible treatments

Dr Phil Smith, medical director of the Omaha unit, would not say what time or where Sacra would arrive, citing public safety and patient confidentiality concerns.

 Smith and several other doctors who head the team for the biocontainment unit repeatedly said Sacra's transfer to Omaha posed no threat to the public, noting Ebola is transmitted through close contact with an infected person.

He said Sacra was in stable condition in Liberia and was able to board the plane to the US under his own power, but added, "He has a long plane ride ahead of him."

Doctors in Omaha will focus on providing him basic care, Smith said, including keeping him hydrated and keeping his vital signs stable. Smith said a team of 35 doctors, nurses and other medical staffers will attend to Sacra.

The team is discussing experimental treatments, including using blood serum from a patient who has recovered from Ebola, Smith said.

"We've been trying to collect as much information on possible treatments as we can," Smith said.

No licensed drugs

There are no licensed drugs or vaccines for the disease, but about a half dozen are in development. None has been tested in humans, but an early trial of one vaccine began this week in the United States.

Much attention has focused on the unproven drug ZMapp, which was given to seven patients, two of whom died. But the limited supply is now exhausted and its developer says it will take months to make even a modest amount.

Sacra's wife, Debbie, said in a news conference at the University of Massachusetts Medical Centre in Worcester that her husband was in good spirits as he boarded the plane on Thursday. She said the couple had known there was a risk of him getting infected with Ebola when he left for Liberia in August.

"I knew he needed to be with the Liberian people," she said. "He was so concerned about the children that were going to die from malaria without hospitalisation and the women who had no place to go to deliver their babies by caesarean section. He's not someone who can stand back if there's a need he can take care of."
