Thomas A. Duncan, who became ill with Ebola after arriving from West Africa in Dallas two weeks ago, succumbed to the virus today (Sunday), reports Reuters. Duncan was fighting for his life at a Dallas hospital on today after his condition worsened to critical, according to the director of the US Centers for Disease Control. The Dallas hospital that admitted him did not recognize the deadly disease at first and sent him home, only for him to return two days later by ambulance.
