I used to work with CASA, and the limits on the funding that was available restricted the research to fatalities. We don't have the resources available to get an understanding of exactly what the extent is of the injuries and also the illnesses that people would be suffering. That is something we hope to do with the organization moving forward as we rebuild to get a better understanding of the extent of the problem.
