Your idea is slightly different, in that you want your population to die as well. In order to do that, I would use the same method I did, but copy stats from one of the One monsters that kill population, such as the Harvester of Sorrows. (Give your units #heal to counter the diseases)

Happy?

I typed many before I actually thought about the ones I knew about, and did not go back and change it incase there were monsters I was overlooking.
