My husband is currently in hospital with Covid, he is on critical care but improving so that’s good. He only tested positive this morning on his 7th test, symptoms began on 11th January, 1st negative on the 12th. Saw GP on 18th who thought covid and said to isolate until 21st despite negative test, another negative test that evening. He was admitted to hospital on the 19th where he tested a further 5 times and treated for covid as that’s what they believed it was. Positive test finally came through this morning. Where do we stand re isolation?
