Really, don't blink with this damn variant.

A few striking things I noticed, including a comparison of the #delta & #omicron surges in #Florida.

Nearly 47,000 cases reported today, 7-day avg just under 30,000.

Blows our delta peak out of the water by almost 8000/day.

🧵

1/13
We continue to lead the country in the % increase in average daily cases compared to two weeks prior.

#Florida has had a 991% increase

But the absolute increase is astonishing - we are now averaging nearly 27,000 more cases EACH DAY compared to 2 weeks ago.

2/13
Whereas only a few weeks ago, we had the LOWEST 7-day cases per capita in the country (largely due to the catastrophe that was the #delta surge)...

We're now 4th highest in the country over the last 7 days, behind only NYC, DC, and NJ.

3/13
If you have enough cases, you'll end up with more hospitalizations.

2 weeks ago
- ADULTS HOSPITALIZED: 1189
- KIDS HOSPITALIZED: 24

Now
- ADULTS HOSPITALIZED: 3364 (183% increase)
- KIDS HOSPITALIZED: 90 (275% increase)

Fig below shows the increase during December alone.

4/13
I ALWAYS want to give appropriate context.

The blue box is what I showed you on the previous tweet.

Our current # for adults (3364) is 5 times less than the #delta peak (~17,000).

Our current # for kids (90) is 2.5 times less than the #delta peak (229).

5/13
But here's the thing.

I mapped the change in daily cases and adults hosp with confirmed C19 during the beginning of the #delta and #omicron waves.

Cases are much higher during omicron's first 2 weeks, but look at those hospitalizations.

We've continued to say...

6/13
Even if the severity of #omicron - whether intrinsic severity or severity after you factor in that we are less immunologically naive...

If you end up with a huge surge in cases, the sheer # of hosps may be very similar to #delta, or God forbid higher.

7/13
2 more things about this fig.

1) Look at how that red dashed line is trending

2) b/c I pair cases with hosps 5 days later, this DOES NOT INCLUDE hosps for the most recent 5 days of cases (& these are the 5 highest we've had during #omicron)

29480 25655 23790 22669 21108

8/13
Here's the same figure, but for #kids hospitalized with confirmed #COVID19.

Already way more at this stage than during the #delta surge.

Again, even though the hosp-to-case ratio is lower during #omicron,

Tons of cases = a lot of hospitalizations.

@COVKIDProject

Again, I can't control the caveats to these data.

1) can't know severity of a given hosp
2) don't know primary reason for hosp
3) don't know how much COVID impacts the hosp

It's still gonna be a considerable problem for our absolutely taxed healthcare professionals.

10/13
Still so much in our #mitigation #toolbox

Perhaps contrary to what you may have heard recently, as I stated when interviewed for this local TV story...

A well-fitting & HIGH-QUALITY mask (eg N95, KN95) is a really good idea. Fits perfectly fine.

Context tweet: at least some data from a large healthcare system in Florida regarding what is being termed "incidental" COVID-19 hospitalizations.

It's not trivial, which would represent some good news.

Your Dec 28, 2021 #COVID19 update

Based on today's CDC updated timeseries #, #Florida now up to 6th highest in total # of new cases over the past 7 days (766 per 100k).

NYC, DC, NJ, NY state, & RI round out a top 5 you don't want to be in.

There's a big BUT...

1/
First, the timeseries did not include the 12/27 data for any state. FL had another 29,059 new cases, increasing its 7-day average daily cases to over 25,600 (highest ever).

Second, all except 11 states have 0 cases logged for 12/26 (incomplete). So, not apples to apples.

2/
I wanted to focus on #hospitalizations.

ADULTS: New confirmed daily admissions have more than doubled in the last week alone (287/day to 581/day)

KIDS: New confirmed daily admissions have nearly tripled in the last week alone (10/day to 29/day)

Quick #Christmas update on #omicron in #Florida following the @HealthyFla weekly report from yesterday.

I've borrowed an image for my dashboard that reflects how it seems spread has occurred (thanks Santa).

Let's have a quick walk-through.

1/15
Here's the overview of metrics.
- cases are surging, setting daily records, approaching new record over 7 days
- more testing than ever before
- both of the above likely underestimated between at-home tests and absence of reinfections in the daily numbers
- hosps increasing

2/15
This county-level infection rate fig blows my mind.
Only 2 weeks separates the left and right maps.

I thought my home county's (Hillsborough) 507% increase was crazy.

But check out these 2-week increases:
- Dade: 1790% (19 times higher)
- Broward: 1437%
- Palm Bch: 1167%

My Lord, things change RAPIDLY with #omicron.

And they are not changing for the good.

Your 12/22 #COVID19 update.

#Cases and #Hospitalizations.

As always, Florida-centric with some national context.

Brace yourselves.

Purview of 7-day avg daily cases over the past 8 wks.

In the first 6 wks in this window, <2000 per day.

Last wk, 2702 per day.

Most recent wk of reported data, 10,904 per day.

# of cases in today's report (20,194) exceeded the WEEKLY TOTAL over any of the past 7 wks.

2/14
To appreciate the rapid rise, here's a map showing change in avg daily cases compared to just 2 weeks ago.

FL - 499% increase (3rd highest: DC, Hawaii)

Detailed #Florida numbers at bottom right of figure.

In my thread last night on just a few of the reasons for D-I-R-T-Y data on #COVID19 #vaccination status, I failed to explain the potential impact of duplicate records being created.

Here's that simplified explanation.

1/5
In the fig, we have what actually happened (top), a situation in which the booster got assigned to a different record (treated as a different person in calculations), and a hopefully rare situation in which all three doses were treated as though they belonged to diff people.

2/5
Here's an example when 7% of people completing a 2-dose series had duplicate records that were created.

Those w/ a completed initial series was UNDERestimated by 6.3%.

Those w/ "only first dose" was OVERestimated by 12.6%.

The "at least one dose" exceeds the pop count!

#COVID19 #vaccination data.

Vax estimates above 100%.

Millions of people seemingly failed to complete their initial 2-dose series.

Unexpectedly low rates of booster uptake.

A thread explaining how these data might be D-I-R-T-Y.

PROBLEM #1: WRONG PLACE OF RESIDENCE

People may be assigned to a county based on where they got the shot and not where they lived. [that's the numerator]

Since the denominator is based on place of residence, the % vaccinated can end up out of whack.

2/16
Problem occurs when misclassification in one direction (calling a non-Hillsborough resident a Hillsborough resident to a greater extent than the opposite direction (calling a Hillsborough resident a non-Hillsborough resident).

More likely to happen for specific age groups.

#Omicron can kiss my a$$.

Now that that's out of the way, a brief #Florida update.

Well, as expected, cases are increasing at a rapid rate. More than a doubling from last week.

1/12
As we dive deeper to the county level, although the increases are pretty consistent, our 3 largest counties in the southeastern part of the state are skyrocketing.

1-week change in 5 largest counties:
- Dade 322%
- Broward 213%
- PB 160%
- Hillsborough 60%
- Orange 50%

2/12
The percent changes for this past week (far right bar) reflect increases for every age group, but most pronounced for those 20-49.

The smallest increase is in the most vaccinated age group (and the most likely to take precautions), those people 65+.
