First Ebola Patient Diagnosed in U.S. Dies From Virus

Thomas Eric Duncan, the first person diagnosed with Ebola in the U.S., died from the virus while in isolation at a Dallas hospital, ending a case that helped bring into sharp focus the nation’s risk from the disease.

The incident showed that Ebola could quietly make its way into the country, and that hospital protocols designed to control it may not always work. At the same time, it rang an alarm for medical professionals and federal officials to tighten the safety net.
