I would certainly take precautions guarding against you getting it from here on out (not sharing drinks, utensils, no kissing!, frequent hand washing, etc.). If you develop symptoms, especially severe ones, then I'd definitely be seeing the doctor as it can cause liver and spleen problems on occasion.
But unless you develop symptoms, I'm not sure there is much a doctor can do for you other than possibly suggest changes to any immunosuppressant medications you may be on. As I think about it though... they could test your blood to see if you've been exposed to it in the past. If you have, then chances are good you won't get sick from it again.
I hope you can avoid it one way or another!
And welcome to the site!
