Yes, we do. When we turn donors away, we record that event and why they were turned away, whatever the reason is.
When we first looked at establishing a deferral for Zika risk, we went back to data that we had collected from Canadian blood donors who travel. We had done an extensive survey in 2014, and we used that as the basis to estimate what our loss of blood donors would be for a 21-day deferral. We were estimating that the loss of blood donors would be just about 3%. From the data we've collected up to about 10 days ago, which is the most recent data I've seen, we are deferring at the rate of just under 3% of donors, who we're asking to please come back in another three weeks and to not donate blood that day.
