ALCORCON, SPAIN - OCTOBER 07:  Animal Rights activists stand outside a block of apartments where a Spanish nurse who tested positive for the Ebola virus lives on October 7, 2014 in Alcorcon, near Madrid, Spain. Her dog is thought to be at risk of being put down as health officials try to keep the virus from spreading. Spanish Health Minister Ana Mato confirmed the nurse had tested positive after treating two Ebola patients that had been brought back to the country from Africa.
