Health workers in protective suits stand near a window at an isolation ward on the sixth floor of Madrid's Carlos III Hospital October 12, 2014. Teresa Romero, 44, the Spanish nurse infected with Ebola was conscious and sitting unaided on Saturday, as three more people joined 12 others hospitalized in Madrid to be monitored for signs of the deadly disease. None of the 15 others still under observation has been diagnosed with Ebola so far, though the Spanish government is under fire for its handling both of Romero's case and the threat of a wider outbreak of the disease.
