Thank you very much, all of you, for your presentations so far.
Actually, the question I was going to ask is on organ donation, mostly because it's an area of personal interest for me. You said that so far no one has been denied an organ donation because of this, but you did talk about the case of stem cells.
We've heard that there might be larger cases or other cases in which we don't know someone has Zika, and they don't know either. What is the risk? Is there a potential that somebody might be refused a donation in the future, whether of an organ or a product like a stem cell or a bone graft or something else that they would be asking for? When it would come to that moment, you said that physicians could say they were going to continue on. I'm guessing they would involve the patient when making that decision. Can you talk about that a little bit more?
