Scottish nurse Pauline Cafferkey faces disciplinary action over claims she concealed her temperature at an Ebola screening on her return to the UK.
She is alleged to have given dishonest answers to medical staff when she returned to Heathrow airport.
It is alleged that she "allowed an incorrect temperature to be recorded" on December 29, 2014 and intended to conceal from Public Health England staff that she had a temperature higher than 38C.
Registered NHS nurse Ms Cafferkey travelled to the West African country at the height of the Ebola crisis to help the sick.
She returned to London and then travelled on to Scotland before being diagnosed, and spent almost a month being treated in an isolation unit at London's Royal Free Hospital.
Ms Cafferkey recovered but was readmitted to hospital on two separate occasions after suffering complications linked to the disease, and at one stage fell critically ill.
In January last year she was treated in isolation for the virus.
