I have a little problem - the plague broke out in Rome and Capua, right after conquest.

Now two of my Generals/Governors are affected:

An over 70 aged Financial Specialist (Governor of Rome because of that) and a new, promising General who just took Capua.

What can I do to:

-> Stop the Plague in Rome and Capua ?

-> How can I save my infected faction members?

-> What must I do - must I not do - to prevent the plague from spreading to other leaders - cities?
