Very quickly, the CNISP, as you referred to, was set up as a surveillance system. It wasn't set up as a research system. And what you're looking for is some research. I think there's lots of evidence to suggest an association. It's that causal proof that needs to be the next step of looking at the evidence of that.
We are going to work with CNISP. We're trying to expand and enhance CNISP; it seems relatively easy to add that question, as you've said. We're going to work with the folks at AMMI, the Association of Medical Microbiology and Infectious Disease, who are the folks who work in the hospitals that do that data collection, to see if we can add it as part of that and take advantage of the existing networks and do a little bit of research with the surveillance network.
