Yes. There's been some behavioural and community-based research that has been done in the last couple of years, but very little. One of the trailblazers in behavioural research for HIV and related STBBIs is Joanne Otis from the University of Quebec in Montreal. She has based her whole life's work on behavioural science and behaviour to see why men will reduce their protection barriers in their sexual behaviour.
That, I think, is the key to understanding what the behaviour is in the MSM population and the whole population in general, because we must not lose sight of the fact that 32.6% of new HIV cases are heterosexual people. There's a big percentage that's heterosexually based.
When we look at MSM and the whole portfolio, at aboriginals, and at different populations, it's extremely important to understand what is the behaviour. Is it the users of opioids? Is it intravenous drug use? Is it because there are new immigrants coming into Canada who look for different alternatives or whatever? That has to be researched. If we're going to find the key, it will be based on behaviour, I find, but it's also scientifically based.
