The fatality rate for COVID-19 appears to be around 1% (there's some debate over the exact figure).

With that 1% as a starting point, it means for every coronavirus death you should have 100 positive tests, if you assume you're finding EVERYONE who's infected.

The UK has 6.44.
In other words, we are failing to detect over 93 out of every 100 cases of the coronavirus.

Portugal (a country we've left off the quarantine exclusion list) by contrast has 27 positive cases per death.

That means Portugal is only missing 73 out of every 100 cases of the virus.
This is important, because if we compare only the number of positive cases, we can be lulled into a false sense of security by what is actually totally inadequate testing.
