I certainly don't support the criminalization of the non-disclosure of HIV. I think that largely has to do with stigma and is really unwarranted.
Personally, I think there are mechanisms under public health law to deal with cases when someone is potentially transmitting HIV, either unknowingly or knowingly. That's the route we've taken in B.C. We really try to steer away from criminalization. Recent prosecutorial guidelines have been issued on trying to discourage people from being charged. I do really think that public health law is the much better route to go than criminal law.
