I've been using the Zoe app since it first appeared and keeping up to date through their info, mainly Tim Spector's YT reports.
In the most recent one he mentioned that our figures, while not 'good', are not as bad as other countries make them look because we do
3 times more testing than any other country. So of course we pick up/confirm a greater proportion of cases. Or put another way, many countries are under-reporting cases (not necessarily deliberately, just different systems, etc.).
Hopefully the CDC will be aware of that factor, though how/if that filters through to the decision makers is another matter ... they love the chart to knee-jerk way of impressing their voters
