It is quite strange that my son is in isolation, but the rest of us are not. My wife, son and I went to Ipswich this morning to have our PCR tests. She and I need them so that we can continue to work (assuming we test negative) on a face to face basis. My son sat in the back wearing his face mask for the trip, other than when he did his test. Afterwards, I worked from home, my work day having had to be changed at short notice to allow this.
My daughter has felt nervous about her brother and also is wary of spending time around us, only being downstairs with us for a short period of time before returning to her room where she had less risk of infection from the rest of us.
If my wife and I test negative, we can return to work having daily tests. If my son tests negative, I am not sure how we will feel as the evidence is that if you have a positive lateral flow test, then you have COVID.
On the plus side, he does not appear too unwell and hopefully, that will continue. His main concern is that he will infect the rest of us, though him keeping his bedroom door shut would help to protect us!
