Australian nurse under observation in UK Ebola centre after airlift from Sierra Leone

An Australian nurse is under observation in the UK for the deadly disease Ebola.

Foreign Minister Julie Bishop said that followed a "low-risk clinical incident" at the Australian-managed Ebola Treatment Centre (ETC) in Sierra Leone.

She said the nurse - whose name hasn't been released for privacy reasons - was transferred to the UK under the agreement secured by the Australian government before establishing the centre.

Ms Bishop said a medical assessment in the UK determined that risk of the nurse developing Ebola remained low.

The nurse wasn't exhibiting any symptoms of the disease.

"The Australian-funded ETC has strict infection prevention protocols in place, and the safety of staff and patients is paramount. To date, 29 patients have recovered from Ebola and been discharged from the centre," she said in a statement.
