Day 7 and the very faintest positive - am I still likely to pass it on within the house?

[Legsout]

This is my test this morning, I’m still congested with full up sinuses and a cough.
I’m desperate to come out of isolation within our home as the sleeping arrangements are less than ideal.
Would I still be likely to be able to pass on covid now?

if its in your house its in your house. The isolation will make no difference either way. The current strains hang in the air for hours.

I’m jealous! Mine is as dark as the control line.

I would continue with the isolation until it’s definitely negative as I have seen a line come back that next day. Keep with the ventilation and mask wearing. What’s one more night?
