The other thing I'd like to add to this is that I think we need to remember that the one really at risk of Zika virus infection is the fetus. We know that for the walking adult, it's a very mild illness, and most people who get it don't even know they have it.
From the perspective of making a clinical decision about transplanting an organ that potentially came from a donor who might have had a holiday in Cancun before they ended up being an organ donor or someone in the stem cell arena, we're not giving stem cell transplants or organ transplants to pregnant ladies, so there's a completely different set of clinical decisions that are made in that framework.
In terms of the actual concern over stem cell donors, we had the case I referred to, which you may have heard of through other avenues. It came up during the time before we had put the deferral in place.
Now that we have that deferral, we are communicating with all of our donors who are in the evaluation phase for possibly becoming stem cell donors. They've been identified as first-level matches or preliminary matches, and we start right up front by telling them that if they have any travel plans, they shouldn't go to any of these risk areas because doing so will preclude them from being donors.
I don't see that that's actually going to be a particular problem for the Canadian transplant centres.
