DALLAS — Two days after he was sent home from a Dallas hospital, the first person to be diagnosed with Ebola in the U.S. was seen vomiting on the ground outside an apartment complex as he was bundled into an ambulance. "His whole family was screaming. He got outside and he was throwing up all over the place," resident Mesud Osmanovic, 21, said on Wednesday, describing the chaotic scene before Thomas Eric Duncan was admitted to Texas Health Presbyterian Hospital on Sunday. Duncan, 42, is in serious condition. Osmanovic said he met the man three times over the years when he was visiting his family. His account could not be independently confirmed by NBC News. Ebola spreads through contact with bodily fluids such as blood or saliva, which health experts say limits its potential to infect others, unlike airborne diseases. While past outbreaks of Ebola killed as many as 90 percent of victims, the current epidemic's fatality rate has averaged about 50 percent in West Africa.
