Nancy Writebol was flown to the US for treatment

Nancy Writebol was flown to the US for treatment after being infected with Ebola in Liberia
 

Nancy Writebol, who was flown to Atlanta for treatment last month, told the Associated Press news agency charities alone cannot handle the response to the disease.

Mrs Writebol and her husband David said about 250 employees at the hospital where she and Dr Sacra worked used thousands of disposable protective suits each week, but it was not enough to protect those doing the initial screenings for Ebola in an emergency room.

"We don't have enough personal protective safety equipment to adequately be able to safely diagnose if a patient has Ebola," David Writebol said, adding Ebola has "overwhelmed the supply chain".

Nurses in Liberia's largest hospital are on strike, refusing to return to work until they are issued with protective equipment.

Dr Sacra, 51, was not treating those infected with Ebola, but delivering babies and treating other patients. He had flown to Liberia shortly after Mrs Writebol and another aid worker were infected.

His plane landed early on Friday morning at a Nebraska Air Force base, arriving at hospital 40 minutes later by ambulance.

He will be treated at a 10-bed special isolation unit at the Nebraska Medical Center in Omaha, the largest of four such units in the US.
