I think,aside from the deaths a pandemic would bring itself,a major concern should be that with the current size of the world's human population and the ability for any disease to spread rapidly across the globe,the very real and possibly more dangerous effects of rotting corpses that can't be buried fast enough will cause secondary epidemics that would strain any society and it's economy.
So in my opinion,H5N1 isn't getting enough attention and with it the aftermath of potential millions of bodies needing to be disposed of rather fast and efficiently.
