Some numbers from Europe hot spots. We were roughly 10-14 days behind Italy I think on the big transmission blowup. However, we enacted our shutdown much quicker. Whereas theirs went into effect March 9th, ours was only a few days later that weekend. So our mitigation efforts, as best I can tell, are about 5 days behind them.
Spain's daily positive new cases peaked at 8,000 from 3/25 through 4/1, and is now down to 2,500 per day.
Italy's daily positive new cases peaked at 6,500 from 3/20 through 3/28, and is now down to 3,000 per day.
Germany's daily positive new cases peaked at 7,000 from 3/26 through 4/4, and is now down to 2,000 per day.
(The UK has a horrible testing shortage, so its not really fair to compare them in this regard, but they are still at their peak at 5,000 new positive cases per day if anybody is wondering.)
Spain's lockdown was actually about the same time as ours. They just sent several hundred thousand people back to work in the last couple of days, as their death count was seen moving past the peak.
What I still find strange is that since our peak new daily positive cases were around 32,000, comparably to everyone else, we should see our daily new positive cases drop to 8-12,000 per day. We were at 27,000 yesterday. This is dramatically different than these countries. We are now on average 2 weeks past their peaks, but not seeing the same decrease we should be based on their data. Its a full month later after the shutdown and we're not seeing a peak. In South Carolina (where I live), we were peaking at 300 new daily cases and yesterday we had 115. In my County (population 500,000) we peaked at around 30 new daily cases (going from memory), and we're now between 5-10 with only 2 total deaths ever. That's the type of change in the data I would expect to see 1 month into a shutdown.
Some have speculated that perhaps a hundred thousand plus tests by private labs are not in our daily total tests numbers. That would certainly explain it if we're actually testing 3x the number of people we were before, but having the same total new daily cases...because we effectively wouldn't have the same number of daily cases - we were just missing a bunch before. But I can't find any confirmation our test volumes have changed much over that time period.
