Cambridge also shows very low, which surprised me when looking at the UK map recently - but then you consider transient populations as suggested.
To anyone against lockdowns, I'm sympathetic, but I'd simply ask what is the alternative answer to hospital capacity that is virtually maxxed out, with waiting lists growing by the millions as a result?
Two of the potential alternatives are highly undesirable to a governing political party (one problem with democracy): A targeted lockdown of the elderly and/or the unvaccinated.
