Fever, severe headache, muscle pain, weakness, diarrhea, vomiting, abdominal pain, and unexplained hemorrhage. They show within 2-21 days of direct exposure, which is within arm's length of a patient showing symptoms (officially, anyway...you can still project virus without being symptomatic if it's in your bloodstream). Death rate is dependent on quality and promptness of care, but it runs about 50-80% depending on where you are. It's nasty, but it's not an airborne virus at this point, so avoiding people who have or may have it is smart.
