The latest from Ken:

He expects to be discharged either today or tomorrow.
They want to finish up the last IV antibiotic schedule.
They were talking about the rehab center, but he'd be there only one-two days so it wouldn't make that much sense. And after that nursing home in Seattle where Wuhan Coronavirus went through like fire on gasoline (5-7 dead) I'd be leery of him staying in any sort of medical/nursing facility.

Off oxygen for three days and maintaining normal blood O2 levels.
Chest X-ray Monday night all clear.
He's craving pizza.

So it seems this is almost over and done with, thankfully.
