Initially, I was glad to see that today's SCC numbers were down, but I believe that is actually bad news. It appears that getting test results back has gotten really bad. As a result, the number of positive tests may be misleadingly low.
If you look at the
Cases by Specimen Collection Date, you might think a miracle has occurred. Monday through Thursday last week (older than the 5-day gray period that is expected to increase) are about 1/3 of the previous week.
If you look at
Testing, the average turnaround time is now up to 2.33 days (IIRC, it had gotten to about 1.5 days). The graph text suggests that the values for the past 7 days may increase as more results come back. That used to be 5 days. But if you look at the graph of the number of tests, the reported tests on Monday July 20 (8 days ago) is about half (56%) of what it was the Monday before that.
I noticed that the CDC reported California had the most tests last week with 7M+ (IIRC, Texas was 2nd with something under 6M).
But something has changed. I knew testing was getting slower, but this is a dramatic drop.
ANOTHER POSSIBILITY: The new California Testing Taskforce guidelines may be discarding(??) tests that used to happen.
According to
guidelines dated July 23, tier 4 testing of individuals ("Other individuals not specified [as Tier 1,2, or 3] including: those who are asymptomatic but believe they have a risk for being actively infected as well as routine testing by employers.") "would be implemented when the state's testing turnaround time, as monitored by CDPH, is less than 48 hours."
We're nowhere near 48 hours. Uh, San Francisco Giants, you've got a problem.

Great find! I hope SMC's lead is followed by other counties soon. I just checked the tables from SCC and it isn't there yet.
Now that we have some data, we can ask the right questions (which I hope they've been asking themselves). Maybe this will shine a spotlight on behavioral changes that the community needs to adopt.
For those that haven't looked, the numbers are very disappointing. I'm hoping that maybe there's some rough edges in the data that will get accounted for and that the situation isn't as bad as it looks.
(L.A. County still claims 95.4% of investigations are initiated within 1 day of being assigned. That, with a case load 20% higher than they designed their staff for. Do you get the idea that I think they're waving a magic wand and saying they did something?)
