Health workers attend a protest outside La Paz Hospital, calling for Spain's Health Minister Ana Mato to resign after a Spanish nurse contracted Ebola, in Madrid October 7, 2014. Four people, including the nurse who tested for Ebola on Monday, were hospitalised and being monitored over suspicion of potential contagion of the deadly disease, Spain's health authorities said on Tuesday. Officials for Madrid's health system told a news conference those hospitalised included the nurse's husband, a traveller from one affected country and another health worker. They also said the nurse, who did not leave Madrid during her vacations, was currently being treated with drip using antibodies from previous infected patients.
