The health of a Spanish nurse with Ebola worsened on Thursday and four other people were put into isolation in Madrid, while the country's government rejected claims its methods for dealing with the disease weren't working and blamed human error.
Teresa Romero, 44, is the first person to have contracted Ebola outside of Africa, after becoming infected by one of two Spanish priests repatriated from Africa with the disease.
In total seven people are in isolation in Madrid, though only Romero has tested positive for Ebola. The others include the nurse's husband and two doctors who cared for her. Three other people were released from the isolation unit late on Wednesday after testing negative.
