The consensus is that so many random factors played out to our disadvantage that preventing the outbreak that led to TEotWaWKI was impossible. We should be thankful that humanity survived, even in its much reduced state.
I'm thinking, perhaps not. Here's a story from a 2009 edition of the Washington Post: Infectious Diseases Study Site Questioned . That's smart, "locate a ... research facility for highly infectious pathogens in a tornado-prone section of Kansas."
I'm hoping that the catastrophe culled out those with such flawed thought processes. As for the present, I would rather we didn't engage in such research, though I suppose we could learn valuable lessons. We must assume, though, that the worst will happen. Not only should we not locate these facility in dangerous regions, they should be isolated from the population, too.
