These data are an estimate of the reproduction (R) number during the COVID-19 pandemic for Wales.

The R number for Wales and UK is no longer being produced by UK Health Security Agency (UKHSA). This follows the recommendation from the Epidemiological Modelling Review Group that was approved for the UK by the four Chief Medical Officers. The StatsWales data will no longer be updated.
