Question to the Department of Health and Social Care:
To ask the Secretary of State for Health and Social Care, if he will publish the methodology the Government is using to calculate the national R rate for covid-19 infections.
The process for formulating the R number is a complex one. The Scientific Pandemic Influenza Group on Modelling (SPI-M), which convenes once a week, builds a consensus on the value of R based on expert scientific advice from multiple academic groups. The Scientific Advisory Group for Emergencies then reviews this and provides advice to the Government on the latest R figure. More information on how R is calculated can be found at the following link:
