The ONS in the UK has been doing some very good work tracking prevalence in the community (and because they understand the statistical processes they're using properly, they update the estimates of past prevalence too). Unfortunately the ONS data is not reported as often in the press because it's updated only weekly, whereas test and trace-based absolute numbers are reported daily even though they're close to useless for population-level or region-level analysis. Unfortunately there's no similarly reliable source aimed at understanding prevalence and spread in institutional settings I'm aware of. This is a particular concern given that institutional settings encompasses hospitals and care homes, where a large portion of the most vulnerable are.
