Household Isolation question

[flippyfloppy]

Household of 4, DD developed symptoms three days before the rest of us. Does DD's isolation period end ten days after her symptoms started or does she match ours as a contact? I can't see any advice online. TiA x

Did she test positive?
Her isolation ends 10 days after her symptoms started.

Her isolation ends after 10 days regardless if others in the house test positive after her

I thought that but doubted myself. Thank you that's great news. Yes symptoms started 14th and tested positive been symptom free since 19th. Three more days for rest of us 😬 x
