Two military healthcare workers who were in close contact with a servicewoman diagnosed with Ebola have returned to the UK for monitoring but are not showing any signs of the disease.
The two, who have not been diagnosed with the disease, travelled on separate EU Medevac flights to Newcastle, before being taken to the city's Royal Victoria Infirmary for monitoring over a 21-day incubation period in line with Ebola response plans.
The pair were identified alongside two other medics as having been in contact with the infected worker.
The two medics and the infected worker were transported back in an RAF plane to the Royal Free Hospital in London yesterday, with the remaining two brought back today.
A spokeswoman for Newcastle Hospitals NHS Foundation Trust said: "This is a precautionary measure. The risk to other patients and wider public from Ebola is very low but all appropriate actions are being taken to protect the public's health."
