– A Fort Hood soldier recently returned from fighting the Ebola outbreak in Liberia was found dead on his doorstep yesterday morning, but officials say conclusive tests have ruled the disease out as a cause. The 24-year-old returned to Texas with his unit last week and the tests were ordered as a precaution after his body was found outside his off-base apartment in Killeen, the AP reports. He had been self-monitoring for fever and other symptoms as troops are required to do for 21 days after leaving Ebola zones, the base says. Defense Department sources say Ebola was a major concern because the soldier was found in or near a pool of vomit, USA Today reports. More tests are being conducted to determine the cause of death.
