I've worked with viruses, have altered their genome, and thus know a bit about them. Although I am not too worried about this becoming armageddon, every epidemic starts out with just a few ‘index’ cases, and this virus could easily affect 100s if not 1000s or more if not dealt with in a serious manner. It is not Shep's place to comment in this manner. There are Ebola experts who are concerned. I would have to give them a bit more credibility than Shep.
Even at thousands that probably puts it killing less American than the flu. It’s TV “news” Shep gets to comment on whatever he wants, and he even gets to be wrong most of the time. Notice there’s a big gap between concern and panic. Experts should be concerned, it’s kind of their job. The rest of us should be tidy, try not to play around in other people’s bodily fluids, we’ll be fine. The only people I want to panic are my bosses up in Canada, who almost closed the office I’m in during the swine flu panic (because when you look from Waterloo Tucson and Mexico City are basically neighbors), I’d love some extra time off.
