ONS: “There has been a large increase in the rates for all re-infections and re-infections with a high viral load since the Omicron variants became most common.”

  • The risk of coronavirus (COVID-19) re-infection was approximately seven times higher in the period when the Omicron variants were most common (20 December 2021 to 4 June 2022), compared with when the Delta variant was most common (17 May to 19 December 2021).
  • Those in older age groups were less likely to be re-infected than those in younger age groups, from 2 July 2020 to 4 June 2022.
