There's no obvious correlation between how seriously Covid affects a patient initially, and its longer term effects.
One of our research programmes is trying to uncover why some people recover fully and quickly, and why others may be affected far longer.
Called NoRCoRP - for Nottingham Recovery from Covid Research Platform - it was set up by Professor Ian Hall, the director of Nottingham Biomedical Research Centre, and includes a range of studies into the long term effects of the illness.
You're going to hear from him and his colleague Professor Charlotte Bolton. Like most of our researchers, they treat patients in hospital clinics, and they realised as long as last summer that some patients who'd had Covid but didn't need hospital treatment initially, seemed to get worse, not better.
