A Spanish hospital has discharged five patients who had been under observation in an isolation ward after having been in contact with a nurse who was infected with Ebola.
Nurse Teresa Romero, 44, was the first person to catch the disease outside west Africa in the current outbreak, which has killed thousands in Liberia, Sierra Leone and Guinea.
She was cleared of the deadly virus by doctors at Madrid's Carlos III hospital this week but not discharged.
The patients who have passed the 21-day quarantine needed to rule out contagion are a doctor, a health centre cleaning woman, two hairdressers and a friend of Ms Romero, according to hospital sources.
The Ebola virus, which is spread through direct contact with bodily fluids of an infected person, came to Spain when the government repatriated two priests who had caught the disease in Liberia and Sierra Leone.
Ms Romero treated both priests, who later died.
Ten other people who had contact with Ms Romero remain in isolation in Madrid's Carlos III hospital, including her husband, though none have shown symptoms.
Another 68 people considered to be at low risk of having caught the disease are staying inside their homes and checking their temperature several times a day.
Meanwhile, a Texas nurse infected with Ebola after caring for a Liberian man who died from the disease no longer has the virus, her family has said.
A statement from Amber Vinson's family, cited by several US media outlets, said the 29-year-old would stay in hospital for further treatment but appeared to have recovered from the disease.
"Amber and our family are ecstatic to receive this latest report on her condition," her mother Debra Barry said in the statement.
Ms Vinson is to be transferred to a different unit at Emory University Hospital and is still being treated in the serious communicable diseases unit, her family said.
She was the second of two nurses diagnosed with Ebola after caring for Thomas Eric Duncan, who succumbed to the disease at Texas Presbyterian Hospital.
Ms Vinson's case sparked alarm after it emerged she had taken a commercial flight to Ohio after caring for Mr Duncan before being diagnosed with the virus.
Another nurse from Texas Presbyterian Hospital, Nina Pham, remains in a stable condition at the National Institutes of Health clinic in Maryland.
US President Barack Obama, meanwhile, called staff at Texas Presbyterian yesterday to thank them for their "courage and perseverance" in helping to combat the disease, the White House said.
Elsewhere, North Korea is to bar entry to foreigners on tourist trips from tomorrow, because of worries over the spread of Ebola.
It was not immediately clear if the North Korean ban also covered non-tourist members of the diplomatic or business community with ties to Pyongyang.
More than 4,800 people have died from Ebola in the deadliest ever outbreak of the disease.
Most of the deaths are in Liberia, Guinea, and Sierra Leone.
