DH tested positive on a LFT, we're waiting for his PCR results now. We have a 2yo that goes to nursery, no more LFT available in the area so I can't test myself. DH is now isolating in one of the bedrooms until we get the PCR results. I start a job on Monday (WFH) but 2yo needs childcare. Our option 1 is that DH keeps isolating or option 2 is that we all isolate as a family. I think option 2 makes most sense. Also, what are the chances of positive LFT and negative PCR?
