Especially given rapid transportation and large populations. Heck we're pretty vulnerable to "home grown" virus's. |
Oh, not as much as you might think. Granted, individuals are very susceptible, but as a species, we're pretty resistant. Any guess what our most effective defense is?
hint- it's something people think about all the time and yet never realize why we have it |
Well Racial variation would be my guess but that is not a foolproof defense against every virus. Think Ebola with a longer incubation period between infection and noticeable symptoms. It's quite possible that a virus will come along that overcomes our resistances and outpaces our containment efforts.
