I wish there was a trusted antibody test because OH and I were both ill in January just before Covid was recognised or being looked for. OH had all the Covid symptoms and ended up being sent to A and E because he developed a nasty rash. We were there for 7 hrs. Full of people coughing and ill. He was diagnosed with having a virus which had attacked his immunity and discharged. Since then they have recognised a rash like this as a Covid symptom.
