I think one thing to remember about AIM testing is that it's not so much intended to prevent infection as it is to prevent the spread of infection. Spread of infection will be prevented only after someone tests positive; i.e. someone (or a few people) have already been victimized. This was of course how the spread of HIV was halted in the industry beyond a few people last year when Darren James tested positive. And so unfortunately I think talent should realize that there's always risk and AIM testing would not eliminate the risk but will only manage it, even if testing were done once a week.
