How do you quarantine a city?

How do you quarantine a city that is under plague?

[LordKhaine]

Don't move anyone in or out of the city.

[Tamur]

Yes, the same way you make a constant in visual basic (geek joke, apologies)

A huge city of mine recently had a bout of plague. I promptly moved the governor out and built a camp for him to stay in until the disease ran its course. He never did contract it. No one else entered or left at all. Not ships, not soldiers, not spies or diplomats. Nothing and no one. That's how you do it.

Interesting, I never thought of doing that. I've lost a few really good governors because of the plague.

[LordKhaine]

Pfffft, my faction leader survived the plague twice. Simply view it as a test of the family members strength. If he fails, he was weak and deserved to die! It's just a shame he didn't live to get his punishment for being so weak!

Hmmm, maybe I've been playing as Parthia too much.

Hey now, we can't all be Catherine the Great...

In my campaigns this is always true. I just have to move the governor and any generals out of the city. Never lost one this way! I don't even bother to retrain the rest of the troops.
I didn't try it though with spies/diplomats.
And, yes, don't move any troops out of the city. It seems that troops that have the plague and are out of a city never recover from it.
