Coronavirus, End of Year Edition, 2022

Coronavirus, End of Year Edition, 2022

By the Numbers

The Numbers: 

Nationwide, the estimated number of cases, using official numbers, continues to rise.    From 350,000 on Dec 7  to over 401,000 on Dec 27.  The official numbers continue be under-counted by a factor of 3-10, depending on the source of the estimate.  

More in keeping with reality, the number of people hospitalized with Covid for this wave has increased from around 30,000 to 34,800 for around the same time period.

The peak number I plotted was 447,000 on Dec 22.  The decline since then probably has to do with insufficient reporting during the Christmas holidays, rather than a significant drop.

The New York Times Interactive graph ( It can be found here... has slightly different numbers and is reporting a slight rise in the number of cases.  My source may not be as accurate as theirs, but I'll stick with it because it is an easy scrape, and is good enough.  This is more about trends than anything else. 

Dominant Variants in the US: 

  BQ's 62%     Holding steady since last report

   BA.5 8%     Half the previous percentage.

    BF.7's  4%   Half the previous percentage

    XBB  18%    Triple from last report

    BN.1  4.0%  Holding steady

All of these are Omicron (BA5) descendants.  All have minor refinements that will make the them more infectious, and nullify some treatments, see below.  The latest booster, which was designed with BA4 and BA5 in mind.  Early studies show that it is effective against these variants.

Per CDC tracker...

 

Free Government Tests (again!)

The federal government will ship you 4 Covid tests for free.  Just go to Covidtest.gov  and fill out the form.  

Odds and Ends...

One of the podcasts I listen too, mainly on long drives (thanks Dennis!), is Skeptics Guide to the Universe. Two of the presenters are MD's, so their credentials are very good when it comes to biological issues.  They had attended an event where they were exposed to the current flu virus.  One had gotten his flu shot, along with the latest bivalent Covid booster, and was uncomfortable for a couple of days.  The other, who had been scheduled for his shots the following week, had symptoms dire enough to almost be hospitalized.

Get your flu shot.

They also had a brief discussion on how the rest of the presenters felt getting both flu and Covid booster at the same time.  One said she had a rough 2 days following the shots, and another reported just a bit of pain around the injection site.  They postulated that if your previous shots were all Moderna, then post shot symptoms were light.  But their statistical sample (3) was too small.  I'll add my my 2 cents.  I got both flu and Covid bivalent with no post shot effects.  My shot record is Moderna, boosters Moderna, J&J, and the last one was Pfizer.

4 more shots and the next one is free!  No, wait...        

I have read that getting mixed makers of the shots offers a little, emphasis on little, more protection.  But that is not the reason for the mixed group of shots.  That had to do with my first 3 being given at the VA in Coatesville, which is 50 minute drive each way, while the others were at Costco, 10 minutes.

Coronavirus, Mid December Edition, 2022

 Coronavirus, Mid December Edition, 2022

By the Numbers
The Numbers: 

Nationwide, the estimated number of cases, using official numbers, has risen.   From 256,000 on Nov 14.  to 350,000 on Dec 7.  The official numbers continue be under-counted by a factor of 3-10, depending on the source of the estimate.

More in keeping with reality, the number of people hospitalized with Covid for this wave has increased from around 22,200 to 30,000 for around the same time period.

The New York Times Interactive graph ( It can be found here... has slightly different numbers and is reporting a slight rise in the number of cases.  My source may not be as accurate as theirs, but I'll stick with it because it is an easy scrape, and is good enough.  This is more about trends than anything else. 

Dominant Variants in the US: 

  BQ's 63% up from 44% in mid November.

   BA.5 15.2%   This was the main variant in October, now down from 79%.

    BF.7's  6.3%   Up from under 7.3% mid November

    XBB  5.5%    Up from nearly naught in November

    BN.1  4.6%  Up from  nearly naught in November

    BA.4's 2.3% Down from  5.7% since mid November.

All of these are Omicron (BA5) descendants.  All have minor refinements that will make the them more infectious, and nullify some treatments, see below.  The latest booster, which was designed with BA4 and BA5 in mind.  Early studies show that it is effective against these variants.

Per CDC tracker...

The major effect of the rise of the BQ variants is that monoclonal antibodies, which once were THE major treatment for Covid, even before the vaccinations were available, are ineffective against the BQ's.  One article on this is here...

Paxlovid continues to be an effective treatment, but needs to be taken early on for best effects.  And Paxlovid is reported as "Under prescribed".  So you may have to push for it.

Hospitalized, Vaccinated v. Unvaccinated.

I know I have written about this before, but it bears repeating.  Of the hospitalized with Covid, 80% continue to be  from the unvaccinated population.  The unvaccinated represent about 21% of the population overall.  

Which works out to be that the unvaccinated are 16 times more likely to be hospitalized from Covid than vaccinated.

A recent article on UC Davis for October 27, has 27 hospitalizations from Covid, 6 are vaccinated.  

The unvaccinated also have worse outcomes, or require more extensive treatment.  In the UC Davis article, of the 27 unvaccinated hospitalized, 5 required ICU care.  None of the vaccinated did.

What is not mentioned in the statistics is if the "unvaccinated" include previously infected Covid.  Which should beget some additional protection.  Though studies have shown not as much as the vaccines.



Free Tests

Free test kits are no longer available via government sources, but are available, free to the user, if you are willing to jump through the hoops, from various stores, paid for my your health insurance.

For example.   Google Blue Cross free covid tests.  you will get a CVS advertisement for 8 free tests, per month.  See Here...  Also available via Medicare, and probably many other insurance plans and outlets like WalMart, Rite Aid, etc...
