The Spanish nurse who contracted Ebola while caring for two infected priests in a Madrid hospital has been cleared of the virus in preliminary tests.
Teresa Romero, 44, became the first person to contract the virus outside West Africa.
Tests on Ms Romero hospitalised earlier this month with a high fever returned negative.
Ms Romero was treated in an isolation unit in a specially-adapted hospital in central Madrid.
Usually patients must take another test within 72 hours to be given the all-clear from the disease.
So far thousands in West Africa have died from Ebola.
The hospital will take another test in a few hours' time.
Ms Romero was treated with a drip of human serum containing antibodies from Ebola sufferers who had survived the disease.
She was also given other drugs which a Spanish government spokeswoman declined to name.
One was the experimental anti-viral medicine favipiravir, El Mundo newspaper said.
Ms Romero is the only known sufferer of Ebola in Spain.
There are a further 15 people in hospital, including Ms Romero's husband, under observation for signs of the disease.
Ebola has killed at least 4,546 people in Liberia, Sierra Leone and Guinea in the recent outbreak, the World Health Organisation said last Friday.
Spain has given its permission for the United States to use US military bases in an operation to send up to 4,000 troops to West Africa to help contain the disease.
Spain will approve requests for the US to use the bases at Rota near Cadiz and at Moron de la Frontera near Seville in southern Spain, the Ministry of Defence said.
