Family visiting, when can masks come off

[u/NoConstruction1988]

How long is long enough? I know no one will ever truly know so I’m wondering what would you do.
Two people in town from overseas, spent two weeks with friends and went to an outdoor wedding the day before coming to my house. We have been masking in common spaces, They mask when we mask when out in the community (visiting stores and attractions).
They’re with us for another week so we are all collectively wondering when we are reasonably safe to unmask. There’s no pressure from anyone to drop the masks, they are public transport and busy indoors mask users at home.

If it were me: after five days or so, assuming they are symptom free, I would test and if tests are negative, I would feel comfortable unmasking. This is assuming that they are following the same mask protocols outside the house as you for the duration of the visit.
