Doctor gives blood for Ebola-infected Dallas nurse

DALLAS (AP) - A Dallas nurse who caught Ebola while treating a Liberian patient who died of the disease has received a plasma transfusion donated by a doctor who beat the virus. Ebola has killed more than 4,000 people in an outbreak the World Health Organization has called "the most severe, acute health emergency seen in modern times." Federal health officials say they are ramping up training for medical workers who deal with the infected.
