Even though the US indeed has implemented widespread testing (and most of Europe hasn't) which equals a higher number of reported cases
This is just dumb; countries like the UK and Spain both have higher testing rates than us, and a fraction of the infection rate.
UK for instance has a 40% HIGHER rate of testing, and less than half the infection rate.
Our problem is much bigger than countries with more or similar testing rates... we should have a much higher testing rate than we do considering the sheer size of our problem and we don't.
On a population of ~330 million, the US has done ~31 million tests.
Which means that give or take 7% - 10% of the population has been tested (of course some medical professionals get tested regularly so those are not 'individual' tests and most countries calculate this by 'tests performed')
Now let's look at the data of a few European countries and I admit I haven't looked at this data in a while:
Italy has done 5 million tests on a population of 60 million. (9%)
Germany has done 6 million tests on a population of 80 million. (7.5%)
The Netherlands has done 400k tests on 20 million people. (2%)
UK 10 million tests on a population of 66 million. (15%)
Poland 1.6 million tests on a population of 40 million. (4%)
Greece ~300k tests on 11 million. (2.5%)
Spain 5 million tests on a population of 50 million. (10%)
France 1.6 million tests on a population of 67 million. (2%)
Interestingly the UK is an outlier and Spain is more or less equal with the US with most countries not performing that many tests.
Russia claims to have done about 20 million tests with a population of 144 million (14%)
