Did he explain the quarantine? For example, if my son were sick, could my husband go to work? Sounds like no, or else what is the point of quarantine?
I'm not sure the money is worth it for him to make all those other people sick, but I generally feel that way any time we have a monster sickness in the house. He is self employed so can usually take a couple of days off if HE is sick.
However, if this thing goes round robin through all of us, there's no way we can stay in the house for a month or how ever long this takes.
