          30        249       8505         2127       991    383
Summary:
  • The U.S. is looking better.
  • The World and India have plateaued, which is better than being on a rise.
  • Country ranking today of new cases:
    • #1  India  
    • #2  Brazil
    • #3  Colombia
    • #4  UK
    • #5  Argentina
    • #6  Indonesia
    • #7  Russia
    • #8  South Africa
    • #9  USA
  • The mortality rate is 2.2%.  Thus in ten days or so:
    • India will continue to have around 1000 deaths/day.
    • Brazil will drop by a factor of two to 1000 deaths/day.
    • The U.S. will increase a bit to 300/day.
  • Of course, the mortality rate depends on age.
  • 39% of COVID-19 deaths in the U.S. occurred in nursing homes.  Click on that graphic to read the details.
  • But what is the asymptomatic rate? 
    • The mortality rate could be as low as 0.5% if the asymptomatic rate is 80%.
    • However, both the CDC and South Korea believe this rate is 30%.
    • Way back in November, Nature reported early studies shows that this rate was as high as 81%, but more recent meta-analysis indicated 17%.
    • Anthony Fauci says 40-45%, and we might not know this rate until later in the summer.
    • The bottom line is that medical experts do not really know what is the asymptomatic rate of COVID-19.
Can asymptomatic cases spread the disease?  At this time, the CDC speculates that 75% of asymptomatic cases are infectious.  And in case you did not know, asymptomatic individuals are afflicted, but show no symptoms.

It depends on the individual, but a COVID-19 patient is infectious for from 10-20 days.  Worse, this individual can spread the disease two days before showing any symptoms.

Here is something to scare you: 66% of venereal disease cases are asymptomatic.  This means that two-thirds of them so afflicted are capable of infecting you even if they show no symptoms!

The seasonal flu has been around forever, so you would think that medical science knows the range of asymptomatic cases depending on the season?  Nope.  However, the field has guessed that the asymptomatic rate of the flu is 50%.  Again, this is the group that most likely spreads the disease.  The ones who are sick stay at home and later warn you by coughing.

Even for the common cold, there is little consensus.  One study indicated that 60.5% of those afflicted with the rhinovirus are asymptomatic.  

On these bases, you would thus surmise that the asymptomatic rate of COVID-19 must be higher than 50%.  And if the ongoing studies cited by Dr. Fauci come to any kind of conclusion, we might know the asymptomatic rate of this disease by September.

I have been selected to exhibit my photos this month at 15 Craigside.  I am featuring the best of my around the world trips, and provide info on the Island Princess world cruise departing Los Angeles for 111 days beginning on 19January2022.  You, too, can sail the globe.  Alas, I look at my photos and can see that mine can't compare with the following:

HONOLULU TO SEATTLE

The story of the day is Hurricane Milton, now a Category 4 at 145 MPH, with a track that has moved further south and the eye projected to make landfall just south of Sarasota.  Good news for Tampa, which is 73 miles north.  Milton will crash into Florida as a Category 4, and is huge, so a lot of problems can still be expected in Tampa Bay with storm surge.  If the eye had crossed into the state just north of Tampa, the damage would have been catastrophic.  Milton is a fast-moving storm, currently at 17 MPH, so as bad as the rainfall will be over Florida, again, a blessing.  The eye will make landfall around 10PM EDT today, and will move into the Atlantic Ocean north of Palm Bay Thursday morning. My first trip to Seattle was in June of 1962 just after I graduated from Stanford University.  Caught a bus. Was called the  Century 21 Exposition .  Also the Seattle World's Fair.  10 million joined me on a six-month run.  My first. These a...

WHY YOU SHOULD CONVERT TO A JAPANESE HIGH TECH TOILET

Did you know that   Oktoberfest   in Germany is mostly in September?  The very first day of Oktoberfest 2021 was supposed to be today, September 18, extending into October 3.  Well, as in 2020, Oktoberfest was cancelled. So why is it called by that month when it is held mostly in September?  The first celebration in 1810 was in October. Did you also know that Oktoberfest is held only in Munich?  These days seven million drink more than a liter ( about three typical cans ) of beer each, costing around $11.  Except for my wife and I when we followed the crowd to board the S-Bahn to the fairgrounds near Old Town.  It was drizzling a bit.  We bought a large pretzel outside of a typical barn where beer is served.  We did not know that you needed to get this inside the hall.  So no one came to serve us beer.  After a while we decided to have lunch, and the restaurant we settled on only served wine.  Thus, we might have been the ...

THE FIRST 84 YEARS OF MY LIFE

The first half of my life was spent preparing myself for my final 42 years.  This was a mostly trying and stressful period involving a less than ideal youth, then struggles to get through school, my first few jobs and accompanying life, ending two months later on a Sunday with  Part 15E , so it was a spiritual conclusion to my final transition.  I never did count the number of actual postings, but I suspect it was around 25 parts.  The ending had to do with golf, the disappearance and re-appearance of an  8-iron cover.  That was the final clue to whether the beyond after death would be eternal gloom or Heaven. Today, I provide only one transition, but hint about a final one, for this, after all, is Sunday.  I'm 84 years old, so let me summarize what happened during the first phase, from 0-42, and follow with the years 42-84.  As this is 2024, that key transition year was 1982. I can't seem to find this photo, but as a one-year old baby, I was fat....
