TB might have Killed off leprosy

looks like survival of the "fittest" holds good there as well!!!!!
 
excatly! i wonder what it might take to "kill off" diseases like cancer and aids... :confused:
 
That would be in the case of cancer, a more aggresive cancer. And in the case of HIV another virus targetting the same cells of the immunesystem. In neither case of course are we going to win in the end. We are just the helpless victim.
