A medical practitioner wearing protective clothing stands next to an isolated patient on the sixth floor of the the Carlos III hospital in Madrid, Spain, Thursday, Oct. 9, 2014. Two doctors who treated a Spanish nurse who contracted Ebola have been admitted to a Madrid hospital for precautionary observation, bringing to six the number being monitored at the center. More than 50 other possible contacts were being monitored. The nurse, who had cared for a Spanish priest who died of Ebola, was the first case of Ebola being transmitted outside of West Africa, where a months-long outbreak has killed at least 3,500 people and infected at least twice as many.
