Another British health worker has been admitted to the Royal Free after potentially being exposed to Ebola from a needle-stick injury.

The hospital in Pond Street confirmed today it had received the patient who may have had contact with the deadly virus while in Sierra Leone.

They arrived in the UK today and are said to not currently have any symptoms.

Royal Free staff will continue to assess the patient and will continue to monitor them for signs of the disease.

Professor Paul Cosford, Public Health England’s director for health protection, said: “The overall risk to the general public from Ebola remains very low. We are confident all appropriate public health actions have been, and will continue to be, taken to support this individual and to protect the public’s health.

“The courage shown by every volunteer, in helping those affected in West Africa and to prevent the spread of Ebola any wider, should be recognised.”

British nurses Pauline Cafferkey and William Pooley both survived the highly-contagious disease after contracting it while treating patients in Sierra Leone last year. They were treated at the Royal Free’s specialist isolation unit.

Earlier this month, two UK military healthcare workers were discharged from the hospital after being kept under observation following needle-stick injuries. They were also treating sufferers in Sierra Leone.

More than 9,500 people have died from the Ebola outbreak in West Africa. No British nationals are among the dead.
