The problem is that flu has disappeared supposedly and we have been so bombarded with covid that every little sniffle it's someone's first thought. The pcr test is so unreliable that it's being recalled so we really have no idea if these people all had covid or how different it is to other sars viruses etc. My family member took 7 months to even start getting better from pneumonia and also had the loss of taste etc and did say had they tested positive when admitted to hospital they would have fully believed it was covid. Even I am looking back and thinking I did have something weird the November before covid was announced, was it covid etc? It's really all we think about now and the brain is powerful. They did say everyone with long covid tests positive with glandular fever... I remember some kids at school getting that and they were off for months on end.
