Okay. That's great. Thank you very much. I appreciate that.
Dr. Fowler, I appreciate your being here. Thank you for everything you're doing.
You talked a little about clinical signs. I'm wondering if you could comment briefly, because there are a lot more clinical signs that we're hearing about. Besides the basic respiratory ones, we're now starting to hear issues of clotting, small strokes; children who might present with discoloration of their toes, etc. Can you comment on those for us, please?
