LA County June 22nd Update (2/4) One thing that caught my attention - is this the hospitalization-to-death lag shown visually? Suggests a 4-week progression which is higher than I thought, but the curves are very similar, and earlier hospitalization data seems unreliable.pic.twitter.com/DZ4tEee6ls
LA County June 22nd Update (3/4) LA County reported an 8.4% positive rate from the past 7d, whereas I'm calculating 9.0% If I understood correctly, they're averaging each day's positivity rate. Mathematically, this is incorrect, because each day should not be weighted equally.pic.twitter.com/TJrvDQygws
LA County June 22nd Update (4/4) Well, there's our protest spike! Unfortunately, the update today bucks the trend of declines in the 65+ age group. Fortunately, the weight of new cases is going to the 18-40 age group and 40-65 age group, with a smaller increase under 18.pic.twitter.com/DSRtPax6ML
LA County June 22nd Update For those following, apparently Dr. Ferrer did connect the recent surge to the protests too (I didn't verify her quote tho) It's harder to see it in the episode-date-based data, which is incomplete for the recent time period. https://twitter.com/mattdpearce/status/1275204296372482048 …pic.twitter.com/X0Xo1XC9vD

LA County June 23rd Update (2/3) It makes sense that % hospitalized would be low if case counts are going up. Hospitalizations are going up too, just not as quickly - hopefully this isn't because they "lag."pic.twitter.com/Iqi9CSPdjH
LA County June 23rd Update (3/3) Have gotten some Qs about linking spikes & protests on the grounds that other cities like NYC didn't see a similar uptick. I have a hunch that Angelenos are less likely to wear masks. Regardless, the spike continues in the 18-64 age group.pic.twitter.com/RgU9dPznrK
Getting national recognition on our record day... LA, I knew you were special

LA County June 24th Update (2/3) Deaths trending downward from an average in the 40s, but hospitalizations are drifting up - not a good sign.pic.twitter.com/51K3HPGwen
LA County June 24th Update (3/3) The spike is less pronounced in the LA County episode-date-based dataset than in the age-based reports, but it's still there. Will be able to tell in hindsight when more data comes in.pic.twitter.com/rRadVa60em
LA County June 25th Update (1/2)
I've feared that they'd change metrics & block progress tracking. Just as we were set to hit 1m tests, reporting stopped

LA County June 25th Update (2/2) Clear concerning upward trend on hospitalizations. I'm still iffy on hospital data quality. We've already seen that it doesn't add up, & they've deprioritized the ever-hospitalized metric. Changing which numbers they report is a huge data risk.pic.twitter.com/LSaLNIAsdx
LA County June 25th Update Addendum: Thanks to those who pointed out testing stats on the website. DK if it's same metric I've been using (didn't qualify LB+Pas before), but it falls in line (report said 15k/day, this metric added 17k) Averages: 9.4% positive 20.0 tests/daypic.twitter.com/ZgECmbV7Qn
And uh...expect to see testing numbers go down? I'm trying to wrap my head around why they would do this? (thanks @NajeebTarazi )
@davideryu can you come back and save us with another test infusion please

LA County June 26th Update (2/3) I previously wondered if deaths might lag hospitaliztns by ~4 wks in LA. Eric Topol suggested similar yesterday (& has since retracted b/c NJ data issue) - so we'll see? Not a good trend on current hospitalizations. https://twitter.com/EricTopol/status/1276502839431294977 …pic.twitter.com/1dHj0R5iwJ

LA County June 27th Update (2/3) Lowest 7-day average deaths since April 13th. Current hospitalizations continue to trend upwards.pic.twitter.com/VWyEJM1IyC
LA County June 27th Update (3/3) 18-40 year-olds continue to be the main driver. It's fascinating to me how they diverged from 40-64 age group at the end of May. (It makes sense in hindsight, it's just interesting still).pic.twitter.com/XC2ayLXhfh
The state of NY has a population of ~20M and 869 current hospitalizations (includes NYC - 8.4M population).
The county of LA has ~10m and 1687 current patients (includes LA - 4m pop).
So LA has about 1/2 the population and 2x the hospitalizations

LA County June 28th Update (2/3) Sharp drop in testing at a time we're seeing an increase in cases. That shows that 1) the increase in cases is very much real (and new measures may be warranted) 2) can't blame "increased" testing what we're seeing.pic.twitter.com/3GPDG2GfiC
LA County June 28th Update (3/3) Again, it's *really* the 18-40 year olds that are the problem. The new measures largely target that and seem warranted. Concerned about the gradual increase in the 65+ age group and what that will mean for hospitalizations and deaths later on.pic.twitter.com/OZjNY9JSSO
There were have it - we're #2 on the hardest hit counties in the US, based on the past 14 days.https://twitter.com/yaneerbaryam/status/1277324161409564672?s=19 …

Key indicators are up, notably hospitalizations - except for "current" hospitalizations (meaning discharges
).
Deaths have started to increase ever so slightly, I'll will wait for something more meaningful before I try to figure out the "lag."pic.twitter.com/jVAnOhrmjS
