I think it would have an impact. Again, it's very difficult to empirically measure people's decisions around this and how they internalize and understand the criminal risk they face. I think the undetectable equals no transmission is an extremely important message to get out to people, but the fact is also that, in a criminal case, people could still be trying to prove that people weren't taking their medications during that sexual exposure.
People need to understand that although we've been fairly successful in getting people on consistent treatment, from day to day and month to month, probably at least 20% of people are not undetectable at one particular time. We're asking people to take daily medications for their whole lives, and we know this is difficult for a lot of people to maintain. If it got down to a criminal case, and this has been my experience, trying to prove whether people were undetectable during that exposure when their last viral load test was months before is a technicality that's very difficult to prove at that time.
It's a great message to have and that would really help, but I think in a court situation people could still be in trouble because they'd be accused of not taking their medications within two weeks or so of the exposure.
The other thing it doesn't mention is condoms, and if people are using condoms, we know that is essentially a foolproof way to prevent HIV transmission, and I think the Criminal Code should embrace that. If you use condoms, there's no foul. Then oral sex is still part of that, and again, there's no evidence that oral sex is a way to transmit HIV. Those other two things that people can do to prevent transmission should be part of this directive.
