Ambiguous: "Unfortunately, if a person who already has a human flu virus swimming around in them gets the bird flu as well, they could easily swap a few genes and start doing something Ebola will almost certainly never do; hang around on kitchen counters and doorknobs and in hugs and kisses. Then we have a problem . The SARS experience taught us that our current medical system is less protection than we thought it was, in fact it doesn't matter if you are going to Asia or staying home, we're all pretty much screwed at that point. To put more perspective on this potential danger the flu we're looking at could, with a few lucky mutations , start acting more like the 1918 Spanish Flu, which killed 20 million people and sickened 1 billion. According to my handy dandy 8th grade percentage figuring technique, that's over 60 million dead and 4 billion sickened within the space of about 10 months. Stats like that don't fit comfortably in the mind, especially in the modern world, where able bodied people are needed to baby sit electrical grids and nuclear weapon that didn't exist in 1918. But surely our modern medical can protect us better than the bloodletting barbers of the 1918? Well, maybe. I'd have a lot more confidence in it if we hadn't just canceled half of our nation's flu shots. "
