Boston-area hospitals are training staff to look out for symptoms of the deadly Ebola virus, since experts now fear that cases of the disease may spread beyond West Africa. While the disease has never been found in North America, medical experts told the The Boston Globe that an outbreak in the US is not outside the realm of possibility: "It's such a small world now," said Dr. Deborah Yokoe, medical director of infection control and hospital epidemiologist at Brigham and Women's Hospital. "We want to be prepared even though the likelihood is small."
