I'm positive I have COVID.

[let's say that differently]

I'm positive, I have COVID.

So a quick šŸ§µ with the new @CDCgov county measures. Unsurprisingly, not great news.

61% of the country lives in a high-level county, based on the hospitalization risk measure.

You can really see the rapid rise in the % of people living in high-risk areas in places like California, Illinois, Kentucky, West Virginia...and even a resurgence in NY and NJ. Other places have remained high.

Compared to last week, 13% of people lived in counties that worsened in their level, compared to 6% of people who lived in a county that improved.

81% of people lived in a county whose risk level did not change.

10 states now have 80% or more of their population living in high-risk counties, led by California (99%), Florida (98%), Hawaii (95%), New Jersey (91%), and Illinois (88%).

More later when the transmission levels are updated for today.

I'll also update my dashboard then.

Thanks for the well-wishes. Fever of 100.9 at its highest, cough, fatigue, and typical man-complaining. Toddler is great, wife improving! #Blessed

1. Will add more later when the transmission levels get updated, but @CDCgov has their new levels out.

55% of the US population lives in a county classified as high risk based on a HOSPITALIZATION-based measure.

By far the highest % in months. Image
2. Last week, there were 4 states with 75% or more of its population in a high risk level.

Now it's 14 states.

Last week, there were 12 states with 50% or more of its population in a high risk level.

Now it's 23 states. Image
3. Here is the county-level change over the past week.

62% of the population was in a county that stayed at the same level

4% of the pop was in a county that improved their level (e.g., high to medium)

35% of the pop was in a county that worsened (e.g., medium to high) Image

1. Despite the current weakness of officially-reported case counts, the @CDCgov county "transmission levels" are problematic.

Virtually everywhere is "high" transmission, without any additional granularity.

So, I modified it, adding two levels to the "high" transmission end. šŸ§µ Image
The current "high" transmission level reflects 100 or more new cases per 100,000 persons in the past 7 days.

Revision:
- "high" is 100-199 per 100k
- "high-200" is 200-299 per 100k
- "high-300" is 300+ per 100kup
3. Based on last Friday's data, we can already see improved ability to distinguish between "high" transmission areas compared to the all red map. Image

1. Here's the more complete šŸ§µ after the CDC update

My how things have changed in just weeks

On May 19, 17% of the US population lived in a "high" level, mostly in the northeast.

On June 30, 33% of the US population lived in a "high" level, almost everywhere but the northeast.
2. In my home state, during that 6 week time period, we went from "high" levels, based on CDC's hospitalization-based measure, in our 3 largest counties in the south

...to 99% of the population living in a county classified as a "high" level
3. Here's the current county-level snapshot of where we are today on the hospitalization-based measure with the less intimidating color scheme (left) to the original transmission-based measure (right)

New @CDCgov community levels are out.

More later (when I get the transmission data update), but a 4-tweet thread so serve as a brief snapshot in pictures.

Your current county-level look.
2/4
 1 in 3 people in the US now lives in a county classified as "high" based on @CDCgov hospitalization-based measure.

That's the highest % in months.

 In Florida, 99% of the population now lives in a "high" level county.

1. It's been a while, but I finally added state-level #COVID19 vaccination data to my dashboard.

For a date you select, it allows you to query various milestones (primary series, 1st booster, 2nd booster) & age groups.

I also allow various denominators to be used.

Quick šŸ§µ
2. Let's say you want the most current data on everyone 18 years and older in terms of receipt of their first booster.

Well, we can calculate the vax rate using the entire population 18+ šŸ‘‡ to get overall scope of getting first boosters in arms. Image
3. Or we can calculate the vax rate using the population 18+ WHO COMPLETED A PRIMARY SERIES šŸ‘‡ to assess how well we are doing in getting first boosters to those who at least came in to get that initial series.

Obviously this will be a higher rate that using the entire pop. Image

1. I'm still waiting for an update of the Community Transmission levels needed to run my typical risk levels analysis, but here's where we'll be with the hospital-based measures.
2. Here's how things have changed from last week.

Blue is improvement

Red is worsening

Gray is no change
3. Another way of looking at the change in levels from last week
