A second study is being done. This is one of the 18 studies under the PHAC initiative, which is looking at incidence and prevalence by geographic location. We're not involved in that. It's being led, I think, by the University of Calgary. That will directly answer your question if there are hot spots or areas where we don't see the disease occurring, and then we can ask what is unique about those areas that may contribute to those differences.
