My wife stayed clear of me during that period - she was still going to the office every day and I slept in the recliner. Also wore a mask (CPAP) most of the time. Kinda nice to have a ventilator on hand.
3 days were really shitty, as I'm prone to get bronchial crap every year. But, I never went to the doctor/ER.
She does not have antibodies, so she has not had it.
I have 2 other friends I know had it. One was completely asymptomatic, and the other was minor.
