In the rules supplement Book of Revelations, it talks about medical care and plagues and the like.
Not that I've been playing as long as many, but I've not heard of a plague in game. Have people suffered bad plagues that hit their populations?
It also talks about training physicians, and how they can help reduce plague. But I was really struck but the last line "Good Medical coverage - 1 physician per 100 population - superb cover, outbreaks are less likely and population growth likely at a higher level."
1 per 100 is 10,000 recruits per million population! Is that even possible to achieve? It boggles me to contemplate it.
