Wanted to throw something out as food for thought. If H5N1 mutates to h2h, and maintains a 50% mortality rate or greater, then consider the current population of the world, which, according to the census is:
02/01/06 6,494,899,830
That could potentially mean 3,247,449,915 could die if the entire world were infected. Now, what do you think are reasonable estimates, if that is unreasonable? In the 1918 pandemic, at least 40mil people died worldwide. Anyone seen a consensus on estimates?
Influenza and in particular avian influenza is endemic in all countries where migrating fowl can be found. This is the case every year. It is a natural mechanism and an inevitable outcome that a highly pathogenic variant emerges, it is as inevitable as complex organisms emerging from simple proteins lets put it that way. EVOLUTION is not static it is not occurring at the centennial, millennial, aeon level or greater, but rather it happens second by second by second....
Sobering thought yes?
