He comes home every weekend and works away during the week. He was home this weekend, Friday to Sunday. I started to feel unwell on Sunday with an upset stomach. By Monday I decided to book myself and husband a covid test as we both developed symptoms. Both got positive results on Tuesday. My daughter felt unwell and also tested positive yesterday. My son has all the same symptoms from late tuesday but has tested negative in his weekly work test. He has gone to a drive test site to have another test as we are certain he has it. Question is if he tests pos can he drive home to isolate with us. He won't be in contact with anyone else in his own car and will stay in the house with us? What does the law say. I cant make head nor tail of it!
