MADRID — Four people, including the nurse who tested for Ebola on Monday, were hospitalized 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 hospitalized included the nurse's husband, a traveler from Nigeria and another health worker.

Officials also said the nurse, who did not leave Madrid during her vacations, was currently being treated with drip using antibodies from previous infected patients.

It was confirmed Monday that the nurse, who had cared for an Ebola patient who contracted the virus in Sierra Leone, was the victim of the first known transmission outside West Africa during the current epidemic.
