I’m just wondering why we haven’t seen a lethal strain similiar to spanish flu. All it take is some mutation occuring from chickens and/or pigs where the virus crosses over to humans and kill many more people than 1918 pandemic because the world is much smaller place today than it was 100 years ago.
A counter argument has been that we are far better able to deal with a budding epidemic than we were some hundred years ago. There have been several discussions (arguments, brawls) about this on Free Republic, if you feel like searching them out.
