More statistics on US states and COVID-19 growth rates. My raw information is from Worldometer. Any errors or misrepresentations are my own.

These tables show all available US states and territories and the COVID-19 data for the last 5 days. I have sorted the states alphabetically and added growth rates for last several days for all states with ranking of each day. Of course, this information changes daily. I have presented the table in two parts because of the screen shot, but it is actually one table in Excel.

Again, results change daily.

State growth rates for November 20, 2022. All information is based on reported information and actual results may be different.

For your information, the top 5 states or territories yesterday in growth rate 7 day average (the worst containment) are: Montana (0.231) with 317,135 cases, West Virginia (0.220) with 612,262 cases, Guam (0.179) with 59,039 cases, New York (0.095) with 6,511,543 cases, and Arkansas (0.078) with 965,475 cases. Montana has been in the top 5 states for 231 of the last 335 days. West Virginia has been in the top 5 states for 349 of the last 440 days. Guam has been in the top 5 states for 28 of the last 28 days. New York has been in the top 5 states for 27 of the last 46 days. Arkansas has been in the top 5 states for 6 of the last 8 days.

Several states have stopped posting new case and new death numbers. I will back calculate where possible.

A column on the right shows the previous day growth rate divided by the 7 day moving average. Red highlight states were over 2.0 yesterday. Yellow highlight states were over 1.5 yesterday. This is an early warning of higher growth rate in states. Many of these states did not report the last several days making this measure more variable for those states.

My calculated growth rate for USA is 0.00376 for yesterday, down from previous day of 0.00460. This is not population or case number weighted. Yesterday, 54 states did not report new cases. It appears some states, particularly Wyoming, are deleting active cases from the count much earlier that others. These differences in the states reporting, makes the growth rate comparisons misleading.

Several states, including Alaska, Mississippi, Nebraska, Rhode Island, South Carolina, and Vermont, may only be reporting on an irregular basis. These states have not reported for at least two weeks.

Daily active case counts have been falling the last several weeks. There have been 187 of last 293 days with decreasing active case numbers.

There have now been 100 million total cases of Covid-19 in the US. This is 30% of the total US population. Reinfections and under reporting will distort the total number of cases.

With new home tests widely available, new case counts are likely under counting the true number of active cases.

To give some context to these changes, I have calculated the average growth rate for each week back to April. The growth rate is calculated as the number of new cases each day divided by the number of active cases for the previous day. There is a typical weekly pattern of rising cases each week and falling case numbers on the weekends. I have calculated the 7 day average of the growth rate for Saturday to Friday of each week.

Using the 7 day growth rate, a calculation can be made of the number of days for the new cases to double. This calculation uses (1+Growth Rate) to the exponential of 1/X and solved for when this equation equals 2 (doubling of new cases). Variable X is the number of days to double the new cases count. I have made this calculation using 14 day and 21 day growth rate averages as well.

A graph using the average for 7, 14, and 21 days and showing the days to double new case counts for April to middle of November is below. Another graph shows the 7 day average new virus cases counts for the same period.

Inspection of the graphs show that when the line for days to double becomes flat, there may soon be a decline or increase to the count of new cases. This has happened three times since April. When the slope of the line for doubling is steep, either going up or down, there is unlikely to be a change soon in the growth or decline in new cases.

The current lines for case doubling now shows some indication of going flat soon. I expect we will see the number of new virus cases continue to increase, but we may have a change of direction starting. Perhaps the changing recommendations for controlling the virus are beginning to have an impact.

There was an error in my original logic posted on November 14. During the upward slope periods of the Days to Double graph, the actual number of daily cases are declining. I reconsidered how to resolve this contradiction in logic.

I have added a new graph with a calculation of the slope of the new case numbers (current case count minus past case count divided by the number of days). The slope of a curve is the rate of change of the plotted line. If we were plotting velocity, the slope would be the acceleration. The slope is a better representation of the virus growth because the slope goes negative when the trend in cases starts going down.

I have updated the graphs for the last two weeks (Nov 6 to Nov 19, 2022).

The New Case Slope graph was up slightly for the past two weeks, and continued in negative range. The Days to Double for the 7 day and 14 day were roughly flat the past two weeks. The 21 day Days to Double was down slightly for the past two weeks. New Case Count average decreased slightly for the past two weeks. Growth Rate Average increased for the past two weeks.

Comments: It looks to me that Covid cases are about to increase at least a little. Not unexpected with cooler weather and more inside activities with crowds. But many more people have some vaccination protection this year.

Stay safe out there. Don't get careless and keep up your defenses.
