May 2021 Summary Statistics

I will present some summary statistics which can explain the trends that we observed during the month of May 2021. This complements similar reports from March, April, May, June, July, August, September, October, November, and December 2020, and January, February, March, and April 2021.

Note - I am considering the extraordinary fatality datum from 27 May as an outlier, and as such I will be largely omitting it from this analysis. I will still use the new daily cases datum from that date.

Total cases on 31 May: 419,611
Total case increase: 8,206

    Still very interesting that VA suburbs have significantly lower fatalities per capita than MD suburbs and DC. Hopefully that will be investigated at some point by authorities or media.

    Your approach to handling the weekend reporting by DC (daily average) is quite reasonable. However, technically it is a simple daily average, not a moving average. A moving average would shift the days included to depict trends over time.

      I stand corrected. Between DC announcing (rather late) about their new reporting protocol, along with the extraordinary fatality datum, I have been forced to improvise as of late, to a certain extent.

End of the Road

My work on this blog is ending as of today. It appears, for better or worse, that the public is moving on from COVID-19, and it doesn't make sense to continue computing statistics for an issue of increasingly marginal public concern. Perhaps it is fitting that this is all occurring in early March, which is almost two years to the date since this all began . My initial effort was to try to do something productive with the situation, particularly as many of us felt fairly helpless. I hope at least some of my analysis was useful to you. I will not be making any more updates, revisions, etc. I will keep all of the posts and data up in perpetuity, or at least as long as Google/Blogger keeps this blog up.

February 3-9 2022 Update

Image
This post updates COVID-19 confirmed case data for the DC Metropolitan area as of 9 February 2022 2022  (covering 3 -9 February) .  The total confirmed cases in the DC area rose by 10,528 t o  933,857   ( average daily increase of 1,504 )  from  the previous total of  923,329 . Fatalities rose  by 210 t o  9,025   ( average daily increase of 30 )  from  the previous total of  8,815 . This will be my last weekly update, although I'll continue to do the monthly update. With the apparent retreat of the omicron variant, which occurred nearly as rapidly as it took off in December, I'm not really sure what relevance the case counts have any more (if they ever did, particularly once vaccines became available). If this is, as some experts claim, approaching an endemic status, then I don't really have much rationale for watching weekly movements.

February 2022 Summary Statistics

Image
I will present some summary statistics which can explain the trends that we observed during the month of February 2022. This complements similar reports from   previous months . The post-peak decline of Omicron continued throughout the month. As of late February, the DC area is under 1,000 reported daily cases. This is the first time the region has been at that level since early December 2021 . Note that the apparent "spike" of infections in mid-late February was driven by single datum for 16 February (10,554 cases), which itself was driven by an unusual datum for Maryland (9,839 cases). I presume this was  backlog, and you will note that the downward trend continued. Total Case Growth Total cases on  31 January: 919,425 Total  cases  on 28 February: 959,092 Total  case  increase: 39,667 Smallest daily case increase: 343 (28 February) Largest daily case increase: 10,554  (16 February) Average daily increase: 1,417 Total Fatality Growth Total fatalities on  31 January: 8,756 T
