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.

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.

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).

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.

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.
