The recommendation is that you don't create new laws, that you would only prosecute very malicious and intentional HIV transmission and that you would use laws of general application.
The law doesn't appear to be colour-blind, right? It tends to fall more heavily on certain populations, and there certainly seems to be a trend of a lot of prosecutions against black men, due to really racist assumptions.
I think you need to address this through public education as well. I noticed in one of the articles I read about the new directive—and the comment stream underneath, which is always very enlightening—that the Canadian public is still woefully ignorant about HIV/AIDS.
I haven't seen any real public education in a long time. I was in first-year university when the crisis hit, and I watched friends I was going to university with start dying. People remember that; they don't remember that it's a chronic but manageable disease now, that people aren't running around deliberately infecting people.
Some leadership by the government in terms of public education, I think would be important as well.
