Yes that's obvious, that would be the same either way so that has nothing to do with it. If Itachi is alive, Danzo can't do jack squat to Sasuke and he knows it.. so if Itachi was at risk of dying due to disease Danzo would know it.. and wait until it killed him.. THEN he would kill Sasuke. Itachi left the village around 13-15yrs old and returned at 18yrs old to show Danzo he was STILL alive. So it seems to be that Itachi was sick when he left.
