I would think the most likely way we're going to get a handle on this, absent a vaccine, is by publishing all the results, by the first half of postcodes, promptly. At the moment, even when we can find Pillars 1 and 2 they're over a week old.
They would need to be easily available online, ideally also read out on the TV and radio news, at least areas where positives are rising. And where there is a steep rise it would be a good idea if Local Authorities would post that up in town and village centres. Yes, we do need the information handed to us on a plate - that's the way to keep the population informed.
Thus informed, the sensible majority can see for themselves if local infection rates in the community are rising and take practical steps to reduce interaction, such as shopping less frequently, delaying visiting, haircuts, less essential shopping and paying close attention to distancing, avoiding indoor gatherings, etc, until the rate drops again. There's not much point in agitating about idiots who won't do that, unfortunately we always have to live with such people, even when they put us at risk.
The alternative is to keep having lockdowns, which probably won't work very well as people travel and which do more and more damage to the economy.
