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)

3/
Instead of new admissions, I'd prefer to focus on people 'currently hospitalized' with confirmed COVID-19.

ADULTS: Exactly 1 week ago, there were 1492. There are now 2702.

Adults in the ICU up an additional 85 patients in last week.

Still WAY below #delta surges.

4/
KIDS: Exactly 1 week ago, there were 49 hospitalized. There are now 74.

The HHS data does not report pediatric ICU beds separately.

Numbers not good, but also well below previous surges.

5/
These pediatric hospitalizations are increasing in an even more pronounced fashion for the country as a whole.

The @HHSGov data many of us rely on does not characterize severity, the primary reason for the hospitalization, etc.

6/
To place these increases in some context, the @nytimes just published a story titled "Omicron Is Not More Severe for Children, Despite Rising Hospitalizations"

nytimes.com/2021/12/28/hea…

This does not mean it's still not a concerning issue.

7/
And when you combine all reported COVID-19 hospitalizations (adult and pediatric) and adjust for population size, here's where Florida falls (dark blue line for FL, look to the far right of the figure).

8/
Finally, these data are dirty. This morning, I retweeted a good thread that tackles some of the issues with interpreting the hospitalization data.

See below:


9/
A SHIFT TO MITIGATION

Although it's not the only tool in our #omicron #toolbox, we do have systematically collected data for vaccinations.

Here's where we stand in getting our seniors optimally immunized. In Florida, only about 55% of seniors fall in this ideal category.

10/
Much more concerning is where we stand on adults younger than 65.

As I've pointed out in previous threads, the snafus with vaccine reporting (eg generation of duplicate records for the same person) will slightly underestimate the % optimally immunized & % not vax.

11/
The @COVKIDProject has excellent immunization dashboards for the pediatric population, so I won't duplicate that info.

covkidproject.org/vaccinations

12/
Finally, here's our immunization progress in the entire US, among all age groups.

We were increasing for a while, but pretty stagnant for past few days. Only 35% optimally immunized. The % fully vaccinated (CDC terminology is a bit misleading).

13/
That's all for now - of course we'll get much more in depth with Friday's @HealthyFla weekly report, which offers more granularity by county and other demographic characteristics.

Stay safe everyone!

14/

Brief COVID update

When speaking with NPR last week, I said the plateauing of hospitalizations for 3 weeks made me feel like a downturn was coming.

In FL, the data are suggestive of improvements in the # of people being hospitalized w/ COVID.

1/ Image
The state-specific trends in the COVID hospital census since June 1 also suggest we are seeing a recent decrease in FL (dk purple), the US as a whole (black), and a number of states.

Yes, FL still has among the highest rates, but we also have one of the oldest populations.

2/ Image
If we indeed see a prolonged decrease in COVID hospitalization census, many of the largest states, who have been below previous pandemic years, will start their decrease right as they approach (but do not exceed) 2022 rates.

Sorry for the delay everyone, a lot going on personally. But I have modified my dashboard to accommodate the CDC reporting changes.

My site focuses on:
1) Hospitalization-based county risk levels
2) Detailed hosp trends
3) Deaths

with links out for wastewater, variants, vax

1/
The "Risk Indicators" page is similar to the older page, but the data upon which indicators are based has changed. There are no longer "risk levels" and "transmission levels", rather levels based exclusively on "confirmed" COVID hospital admission rates over the prior 7 days.

2/ ImageImageImageImage
The "Hospitalizations" page has not changed much. Still starts out with a Florida-centric look and then gives a lot of state- and age-specific census and admission numbers, rates, and rankings.

It's been a while since I've done a #COVID update.

These are national weekly @CDCgov "community levels" based primarily on hospitalization rates.

This past week has been the "best" since April of last year with <1% of the population living in a high-level county.

1/ Image
Of course, this comes with the following caveats according to the CDC, with likely underestimation of levels in Hawaii and Mississippi, and overestimation in several counties in Georgia and Arizona.

2/ Image
Transmission levels are likely to be grossly underreported, but as we look at them over time, are showing modest improvement (LEFT).

This is in agreement with the regional wastewater monitoring data, which also shows improvements over the last 6 weeks (RIGHT).

1/ Updated my #COVID19 dashboard - wanted to do a quick thread on some clearly emerging trends.

covid19florida.mystrikingly.com
2/ Below are adult inpatient hospital census rates for each state since May 1, 2022. Only "confirmed" (as opposed to suspected) COVID hospitalizations are included.

The orange and red coloring suggests recent increases over the past week. Image
3/ But for context, below are the inpatient census stats for adults throughout the pandemic - for most states, we remain well below the worst parts of the pandemic (not that that should be the bar we are trying to avoid). Image

1/ I've continued to see graphics like the one below served as evidence that COVID vaccines do not work.

Why? Because the NUMBER of COVID-19 deaths among vax people is nearly the same (or even more than) among unvaccinated people.

Quick 11-tweet thread on why this is misleading
2/ I'm going to keep this SIMPLE. This is NOT about infection-acquired immunity vs. vax-acquired immunity. This is just about counts vs. rates.

Assume that vax efficacy is 90% in people 65+.

Monthly COVID mortality rates:
- not vaccinated (20 per 100k)
- vaccinated (2 per 100k)
3/ Assume 3 different vax realities among seniors in the US, and assume pop of 50 million.

Vax rates of 5%, 50%, and 95%.

In the figure, under each scenario, I show the vax vs. non-vax distribution of:
1. the population
2. COVID deaths

@cmzimmer1803 - a few thoughts

1/ We absolutely should be concerned with the changing proportions of variants that are ESTIMATED to be circulating in recent weeks.

Due to their characteristics and increasing make-up of new cases, the pose a threat.
2/ Clearly, part of our genomic surveillance efforts are to have TIMELY information when more concerning variants are increasing in relative prevalence. In this case, it appears we lost some time (I was wondering why those variants were not yet showing up).
3/ BUT, I don't tend to jump to an accusation of something nefarious.

The beginning of the footnote states that variants circulating <1% are grouped into "other". Image
