The Spanish health minister has confirmed that a nurse who treated a victim of Ebola in Madrid has tested positive for the disease.
The nurse is said to be the first person in the current outbreak known to have contracted Ebola outside Africa.
Health Minister Ana Mato said the woman was part of the team that treated Spanish priest Manuel Garcia Viejo, who died of the virus on 25 September.
Some 3,400 people have died in the outbreak – mostly in West Africa.
The Spanish nurse is in a stable condition, Reuters quoted health officials as saying. She started to feel ill last week when she was on holiday.
The nurse was admitted to hospital in Alcorcon, near Madrid, on Monday morning with a high fever, Ms Mato said.
Doctors isolated the emergency treatment room.
The infection was confirmed by two tests, the minister said.
