A British military healthcare worker has been brought back to the UK from Sierra Leone for Ebola monitoring, the BBC reported on Saturday.
The individual suffered a needle-stick injury while treating a patient in the West African country, which is among those affected by the Ebola outbreak.
The person has been admitted to the Royal Free Hospital in north London, Public Health England (PHE) said.
More than 22,000 people have been infected with Ebola and 8,795 have died in Sierra Leone, Guinea and Liberia.
The individual does not have symptoms but it is likely they have been exposed to the virus, the Royal Free said.
The patient arrived back in the UK on Saturday on board an RAF flight and will be monitored for the remainder of their 21-day incubation period.
Needle-stick injuries involve a piercing of the skin by a sharp instrument or object, typically a needle.
The Royal Free is home to a specialist unit for infectious diseases patients.
