Hunting for the guinea pig infection

So I don't play SIMS, but I am interested in the "guinea pig disease" from a computing history perspective - it's an interesting meta twist on the virus concept.

As I understand it, there were at least two generations of this. 

SIMS1 : The "Guinea Pig Disease" that you caught from being bitten by a guinea pig if you didn't keep the cage tidy. It was introduced in the "Living Large/Living It Up" expansion. I read somewhere that this disease was later patched to become less deadly.

SIMS4: "Rabid Rodent Fever" caught in a similar way. It was introduced in the "My First Pet Stuff" expansion.

I'm specifically looking for infected lot/household/character/save files to study.
Anyone have a clue as to where I can find such things?
