A second Briton has been diagnosed with the Ebola virus.

The female military healthcare worker, who is based in Sierra Leone, had a positive diagnosis. It follows the case of Scots nurse Pauline Cafferkey who made a complete recovery after taking ill in December.

It is likely the patient will be flown to London for treatment at the UK's only specialist hospital for treating the disease, the Royal Free, in London.

Ms Cafferkey, who caught the disease while working for the Save The Children charity in Freetown, Sierra Leone, spent several weeks in isolation at the hospital before being released.

The announcement of the latest case has been made by Public Health England. It did not reveal the person's identity, gender or where he or she is originally from.

It said a formal decision whether the individual will be evacuated to the UK for treatment has not yet been made.

However, an investigation has been launched into how the person became infected.

A spokesman for Public Health England said: "Any individuals identified as having had close contact will be assessed and a clinical decision made regarding bringing them to the UK.

"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."

Ms Cafferkey, 39, who works at a health centre in Blantyre, said following her release that she was lucky to be alive but had no plans to return to Sierra Leone where she was a volunteer.

She added: "I am just happy to be alive. I still don't feel 100%, I feel quite weak."
