OK, if I were that deputy, I would NOT have walked into the clinic. I’d have gotten into my own car, and called them from the parking lot, asking what I should do, where I might go to expose the fewest people possible, preferably not to expose anyone not previously exposed.
If the deputy has Ebola, he would not be thinking clearly. First symptom is a massive headache as the Ebola flows into the brain via the blood stream.
