In terms of disease surveillance of the wild pig population, one of the files we're working on with the Canadian Food Inspection Agency is in on how we do that, and how we do it in a very systematic, coordinated fashion so that first, we do the job properly— there is no sense in trying to do half of it. Second, we need to be ready to respond if we do find something. This becomes another element of the discussion.
Testing, and how to do it—the physical test, and whatnot—is in place. To your point about the complexity of finding and trapping them, are there some sentinels we could use on the landscape that we could...? If we have pigs outdoors, and we know where they are and where they are processed, or harvested, could we use them as an indicator of the disease status of the wild population, given that there is interaction between the two populations?
Those sorts of things are in play, and, of course, Dr. Komal will be in a little better space for you on that.
Fundamental to that is: Where is the population you can focus on, so that your sampling procedures are appropriate for the risk?
