LONDON — A British military healthcare worker who has contracted the Ebola virus was being flown from Sierra Leone to the UK for treatment Thursday.

Mashable understands that the aircraft is airborne and a further statement on the woman’s condition is due later this morning.

The woman, who has not yet been named, was reportedly working at an Ebola treatment centre in Kerry Town, southwest of the capital Freetown.

Public Health England confirmed Wednesday evening that the healthcare worker had contracted the virus and said an investigation was being launched into how the worker was exposed.

“Any individuals identified as having had close contact will be assessed and, if necessary, a clinical decision made regarding bringing them to the UK,” it said in a statement.

“The UK has robust, well-developed and well-tested systems for managing Ebola and the overall risk to the public in the UK continues to be very low.”

This is the third British health worker to be tested positive for Ebola.

Nurses Will Pooley and Pauline Cafferkey were infected with the virus in West Africa last year, but both eventually made full recoveries.

Nearly 10,000 people are thought to have died from the current Ebola outbreak.
