Theoretical as we're ok at the moment! So, if one child shows symptoms, either cough or fever, how would you manage it as a family? A child can't be left in a room with food left outside the door on a tray, so there would have to be interaction.
Ergo, everyone in the house goes onto "communal isolation"?
(Obviously I'm taking about younger children, I'm sure teens can self isolate as long as they have an X Box and enough cans of Monster
)
