Ok, there isn't much to talk about this way because it hasn't been coded yet (yes, after more than 5 years of planning). The game creators intended to create diseases, and every city would need a doctor to save the infected. If they have yet such intentions, we don't know, it appears they are more interested in creating new games (Shogun Kingdoms!) instead of finishing RK.
