Plagues mod creation question

[neoiq5719]

Every time we have a plague we say, well that´s ok it´s only 10% of my budget and minor unrest, I´ll deal with it later. My question is what files have to be tampered with in order to make the plague rise the percentage with each turn when left unattended thus making public unrest much worse and income too?
thx

Might need to be scripted but it’s a nice idea
