Absolutely stay home, Hugh. Even with great prognoses, no one should be left to fight cancer alone. And best wishes to you both. Indeed, COVID-19 (which my system's medical director is calling "2019-nCoV") may put a damper on our upcoming F2F. I personally don't think we should do anything differently for now, except: 1) Council members may want to hold off on actually purchasing non-refundable flights or lodging for another few weeks; 2) Peter should see if we can get a nice high-speed computer for Skyping people in at the venue. Then in mid-March we should re-evaluate the situation.
We should perhaps be thinking about contingency plans for the F2F, in case we're hit by travel restrictions related to Covid-19. I'm not suggesting calling it off at this stage, but we should be aware of the risks. I'll note that Facebook tells me Elena Pierazzo is under 2 weeks quarantine at home after returning from Italy. So it's far from impossible.
And that said, I will almost certainly not be able to make it in person. If things go according to plan, my wife will be in the middle of radiation therapy then. (It's ok—her prognosis is excellent, given what we know right now, but I'm not going to leave for several days under those conditions.) I'd like to participate remotely to the extent I can.
