The US is now performing 100K CV tests per day, thanks to a new 5 minute test we developed. It took 5 hours +/- before.
The US has exceeded 1,000,000 completed tests.
Both of those numbers exceeds any and all other nations, including China -- even though they started much sooner.
We stopped the distribution of (faulty) masks from China in the US. That action alone may have prevent thousands of new cases, particularly among healthcare workers and first responders.
So, if you read/hear that the US has identified more CV cases than any other country, it might be because we are screening more people in less time than any other country. This should help reduce the rate of transmission significantly as new cases are isolated before they spread it to more people.
