I don't want this to turn into airport screening. That's for sure, and I will say that at the outset, but there is a form of screening we are doing for hospital-admitted patients who fit certain risk factors. It is not simply visitors. It's true that visitors who come into the hospital, who walk in, might have a drug-resistant bug on them, but they're not necessarily transmitting infections. Many people are carrying these infections. If they become ill and then have an intravenous put in or end up on dialysis or on a breathing machine, that very bug that's living on them as a commensal now becomes a pathogen.
Finding those people who are carriers of those bugs, if they fit certain criteria, is becoming a subject of great interest. That's actually a lab resource issue. For example, we, in my hospital, have implemented a selective screening protocol, as per our province's guidelines, to look for carriage. Again, it can be very resource-intensive to chase something that's not common. It's sort of like chasing, at airport security, the killer maple syrup that's out there that someone's bringing onto the airplane. It is the same idea. We have to be careful that we don't turn this into airport screening. It has to be selective and targeted. The technology has to be there, and the support and resources for a hospital to add that to its budget have to be there, which speaks to a point I made earlier.
