COVID Infection estimates in our models are provided at two levels:

Time Adjusted, this is a cumulative infection rate estimate and is calculated on the assumption that every part of the UK started to become infected at exactly the same time point.

AS iS, this is an estimate of the current infection rate defined as the proportion of the population aged over 10 that has been infected at some point with COVID-19.

Both models are regularly updated to include newly released information and data.
