I would like to address the importance of evidence-based policy development. Being able to measure the magnitude of the problem, being able to look at it over time to see whether it is increasing or decreasing, being able to look at risk factors and who is most affected in the population, and learning from different communities and what they've done to address the issue are all extremely important. This would give us not only an estimate of the burden, but also an idea of what resources may be needed and where we need to target the resources.
