What are you basing your hypothesis that testing is the single variable that's the difference between countries that had fewer overall cases of Covid19?
Within the same country, America, New York with it's dense population and reliance on public transport has faired much worse than California which has a more spread out population and a state with very little provision for public transport, yet testing is the variable you think is responsible?
Another ridiculous post.
It's hardly my own hypothesis so untwist your knickers, Mavis. Pretty much every scientist and medical professional offering advice on the pandemic agrees that testing is the key to beating it. The US might be testing large numbers now but when this all started they didn't believe in it, so much so that their own developed tests weren't effective, often failing. They still aren't. But that's unsurprising given how their leader felt about the pandemic as a whole. And the UK has been the same with their view on testing. Testing and isolating people has been a key factor in getting this under control. That's been highlighted by, well, those countries that have it under control. Just do a simple search on how South Korea managed to control theirs and you'll see that within something like a few days they'd already built drive-in testing centres so people could be tested and have a result within 3 days. So again, it's not based on guesswork. It's proven fact.
Oh Look! said:Expansive testing, contact tracing and quarantining have proved successful in reducing the spread of Covid-19 in South Korea
They also imposed far more severe border restrictions for those entering the country. Something which the US and the UK haven't done at all. But yeah, Trump's usual "I did a ban on China" was unprecedented and was met with criticism. Yep, criticism because it wasn't enough!
I suppose your next argument will be that what works to contain the virus in one country can't possibly work in another, because, who knows what stupid reason you'll find to argue against the facts.
