These are some of the major datasets.

Obviously, I link a lot of these together, add in denominator data, calculate a bunch of different metrics from what is provided, and spend much of my effort making your interaction w the data as informative & easy-to-use as possible.

13/

The data they collect/report are the same as you encounter on my site, w some value-added goodies.

I have to clarify this every once in a while.

I don't get millions of $$ to collect data myself.

So, I rely on the hard work of federal, state, & local agency employees.

@CDCgov

PLEASE do not use the @CDCgov data on deaths to compare #COVID19 #mortality per capita in #Florida to other states.

Below, I created a viz from the CDC COVID Tracker to compare 5 states. Florida is the green line and the red arrow shows a recent decrease.

1/5

https://twitter.com/JasonSalemi/status/1487192817080287237

Despite that suggested DECREASE in FL...

I just tweeted this out highlighting the recent INCREASE (almost a doubling) is reported COVID-19 deaths this week.

https://twitter.com/JasonSalemi/status/1487192817080287237

What gives?

2/5

@CDCgov

The way in which states report mortality data to @CDCgov is not the same. Almost all report based on date reported.

FL reports by date of death

That is NOT a criticism - I like the way FL reports it so I can calc both types of curves - but it is a caution for comparison.

We always talk about how #COVID19 deaths are a lagged indicator.

So far, our omicron-dominant peak in #Florida using the 7-day avg # of cases, was on 1/11/22, at >65,000 per day.

Since then, we have been on the decline, now at just under 30,000 per day.

What about #deaths?

1/

@HealthyFla

Well, over the last 5 weeks in #Florida, from 12/10/21 to 1/20/22, the number of newly reported deaths each week (daily avg) has been:

- 122 (17/d)
- 162 (23/d)
- 184 (26/d)
- 470 (67/d)
- 605 (86/d)

Tomorrow, we will get our @HealthyFla weekly report.

2/

My guess (and it is just a guess) will be that we will have learned of between 1000 & 1200 new #COVID19 deaths since the prior report.

That's in the neighborhood of 140-170 per day.

So, as expected (this is not new info), most metrics are improving, but deaths are rising.

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.

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)

@HealthyFla

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.

1/14

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.
