I would but I have a young child and spouse. It's not even so much the risk of serious medical complications for me, it's the complications involved in isolating myself, if that were even possible. It's one thing to increase your risk of exposure with a family; it's another to deliberately infect yourself. Definitely not saying it's morally wrong necessarily, just that I haven't quite figured out a way to do it in which my family would feel ok with it or understand.
I volunteered yesterday after seeing this article. To be clear, this is a very early expression of interest and there is no specific human challenge trial which is ready to begin at this time. Consequently, the exact trial implementation details are to be determined.
That said, I would be shocked if any such trial didn't involve the isolation of subjects in provided accommodations for the full duration of the study. It would be necessary on ethical grounds for the purpose of community safety. Obviously, that doesn't mean you should volunteer (it is still a risk to your health and extended isolation from your family would suck), but they aren't just going to infect you and then send you home to come back in a few weeks.
