Reposting what @Redtoothbrush posted on the previous thread as I thought it was interesting and important:
The big change today is that the government are officially saying they are no longer trying to stop the disease in this country as they no longer believe that to be possible.
Everyone on this thread needs to understand this fundamental shift in policy.
The situation is now that the government want some of us to catch covid-19 to get the ball rolling on this, so that we can peak in May as that fits with planning and doesn't prolong things even further.
This means that there is no point in stopping travel abroad. It would damage the economy and if most cases are imported atm, then that's not a good thing either.
In some ways testing at this stage is now about understanding the spread of the disease. The point in contact tracing becomes not about stopping numbers but about knowing where the hot spots are so they can manage the spread of the disease rather than stop it in its tracks.
Any school closures will be localised and will be rolling from place to place. One place will get a certain number of infections and will be shut down for a while to slow things down. The idea being that the whole country does not shut down at the same time. (Also means you can draft in health care staff from other areas more easily too).
So the number of cases we get moves from being about individuals to cold hard numbers.
