Sorry being dim about lateral flows etc. DD 21 who lives away has just had a positive lateral flow (no symptoms). Her friends are dropping like flies too. She’s on her own in her student house and feels very lonely and was coming home today (just me at home) so have told her to come anyway and she’ll stay in her room which is in the top of the house and I’ll leave her food at the door. I’m triple jabbed, she’s double jabbed. She needs to do a PCR pronto doesn’t she? My 90 year old mum was going to come on Xmas Day but can only come if DD has a negative PCR beforehand and not sure if there’s enough time now. That’s right isn’t it? Also if DD does another lateral flow today and that’s negative, where does that leave us? Thank you!
