By the time Martin Salia arrived on a chartered medical jet at the Nebraska Medical Center over the weekend, his kidneys had failed, he didn’t respond to someone calling his name, and he was barely breathing.In the end, Salia was too sick, his body riddled with the deadly virus. He died early Monday, more than 5,000 miles from the hopeful colleagues who 10 days ago rejoiced with him when an initial test for Ebola came back negative. Salia’s death highlights what experts say is a critical need in the ongoing fight against the worst Ebola outbreak in history: the ability to quickly and accurately diagnose the disease in order to halt its spread and give patients the best chance for survival. “Everybody realizes that is an important goal,” said Thomas Geisbert, a professor at UTMB and a veteran Ebola researcher. “The earlier you treat, your success rate goes up dramatically.” The news also appears in the Pittsburgh Post-Gazette.
