General description

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

An R value of 1 means that on average every person who is infected will infect 1 other person, meaning the total number of infections is stable. If R is 2, on average, each infected person infects 2 more people. If R is 0.5 then on average for each 2 infected people, there will be only 1 new infection. If R is greater than 1 the epidemic is growing, if R is less than 1 the epidemic is shrinking. The higher R is above 1, the more people 1 infected person infects and so the faster the epidemic grows.

The data are taken from management information and are subject to change. They have not been subject to the same validation processes undertaken for official statistical releases.

Data collection and calculation

Wales use UK Health Security Agency (UKHSA) estimates of the R value and growth rate. Several academic groups individually estimate the R value and growth rate using different data streams, modelling techniques and assumptions.

To capture the inherent uncertainty in the R value and growth rate, the individual estimates are combined into a single range for each metric that is based on the evidence available at the time and provide an indication of the reliability of the estimate. This combination process is currently done using CrystalCast Software by UKHSA
