"Reinfections should be included in Covid figures for the UK as soon as possible, scientists have said, amid warnings that up to 15% of Omicron cases could be people who have had coronavirus before. At present, daily Covid case figures – which reflect the number of infections picked up by testing – do not include reinfections... According to a report released by researchers at Imperial College London last month, the risk of reinfection with Omicron is more than five times higher than with Delta... The Guardian understands that reinfections were not included in the case figures published on the government’s dashboard at the start of the pandemic as it was uncertain at the time whether it was possible to be reinfected."
