When I was wanting to move to the UK and work (I live in Australia) I was asked to provide a blood test for hep c. I don't know how it is anywhere else. In Oz there is no testing but all health professionals with a blood born virus must be aware of there infectious status and may not perform exposure prone proceedure (EPP's). This is more in place for dentists and surgeons so don't worry, you are not putting your patients in danger by nursing them. That is even if you have contracted hep c, which is highly unlikely to occur in a long term monogamous relationship.
