Fifty being monitored for Ebola in Spain

Three more people have been placed under quarantine for Ebola at a Madrid hospital where a Spanish nurse became infected, while more than 50 other people are being monitored.

The nurse, who had cared for a Spanish priest who died of Ebola, was the first case of it being transmitted outside West Africa, where a months-long outbreak has killed 3,500 people and infected twice as many.
