My brother sent me this today. 

Subject: Fwd: layman terms
This post puts the Coronavirus in layman terms and helped me understand better. Maybe it will help you too!

This is from an immunologist at Johns Hopkins University:

Feeling confused as to why Coronavirus is a bigger deal than Seasonal flu? Here it is in a nutshell. I hope this helps. Feel free to share this to others who donít understand...

It has to do with RNA sequencing.... I.e. genetics.

Seasonal flu is an ďall human virusĒ. The DNA/RNA chains that make up the virus are recognized by the human immune system. This means that your body has some immunity to it before it comes around each year... you get immunity two ways...through exposure to a virus, or by getting a flu shot.

Novel viruses, come from animals.... the WHO tracks novel viruses in animals, (sometimes for years watching for mutations). Usually these viruses only transfer from animal to animal (pigs in the case of H1N1) (birds in the case of the Spanish flu). But once, one of these animal viruses mutates, and starts to transfer from animals to humans... then itís a problem, Why? Because we have no natural or acquired immunity.. the RNA sequencing of the genes inside the virus isnít human, and the human immune system doesnít recognize it so, we canít fight it off.

Now.... sometimes, the mutation only allows transfer from animal to human, for years itís only transmission is from an infected animal to a human before it finally mutates so that it can now transfer human to human... once that happens..we have a new contagion phase. And depending on the fashion of this new mutation, thats what decides how contagious, or how deadly itís gonna be..

H1N1 was deadly....but it did not mutate in a way that was as deadly as the Spanish flu. Itís RNA was slower to mutate and it attacked its host differently, too.

Fast forward.

Now, here comes this Coronavirus... it existed in animals only, for nobody knows how long...but one day, at an animal market, in Wuhan China, in December 2019, it mutated and made the jump from animal to people. At first, only animals could give it to a  person... But here is the scary part.... in just TWO WEEKS it mutated again and gained the ability to jump from human to human. Scientists call this quick ability, ďslipperyĒ

This Coronavirus, not being in any form a ďhumanĒ virus (whereas we would all have some natural or acquired immunity). Took off like a rocket. And this was because, Humans have no known immunity...doctors have no known medicines for it.

And it just so happens that this particular mutated animal virus, changed itself in such a way the way that it causes great damage to human lungs..

Thatís why Coronavirus is different from seasonal flu, or H1N1 or any other type of influenza.... this one is slippery! And itís a lung eater...And, itís already mutated AGAIN, so that we now have two strains to deal with, strain s, and strain L....which makes it twice as hard to develop a vaccine.

We really have no tools in our shed, with this. History has shown that fast and immediate closings of public places has helped in the past pandemics. Philadelphia and Baltimore were reluctant to close events in 1918 and they were the hardest hit in the US during the Spanish Flu.

Factoid: Henry VIII stayed in his room and allowed no one near him, till the Black Plague passed...(honestly...I understand him so much better now). Just like us, he had no tools in his shed, except social isolation...

And let me end by saying....right now itís hitting older folks harder... but this genome is so slippery...if it mutates again (and it will). Who is to say, what it will do next.

Be smart folks... acting like youíre unafraid is so not cool right now.  Stay safe everyone.

#flattenthecurve. Stay home folks... and share this to those that just are not catching on. 🤓

We are doing fine up here.  Just bored out of our minds.  Alaska had its first Covid-19 death the other day in Anchorage.  It was an older Alaska native lady who also had other serious medical issues.  In response, the governor has mandated a ďstay inĒ policy, and everyone is asked to stay at home unless itís absolutely necessary to go out.  We will need to pick up some groceries in the next day or two, so that will be our next ďbigĒ adventure.  Weíre considering ordering them online and just picking them up outside the grocery store.  Iím not sure I trust someone else to choose our produce and meat for us, though.  Tomorrow I have a cardiologist appointment in Anchorage to meet with a new doctor.  The doctor whose care I was under moved back to California to care for her mother who is ailing, so theyíve assigned a new cardiologist.

Meanwhile, life goes on, as I hope it is for all of you.  This hunkering down is boring, but itís the safe way to flatten the curve, as they say.  Hang in there, folks.  It wonít last forever.  God bless you all, and care for you all.

I heard a good synopsis on why this virus is different from others like SARS or Swine Flu that make the spread harder to control.  1) It has a long incubation period in which at least part of you are contagious.  2) It lingers on surfaces longer than other virus 3) It attacks the respiratory system especially the lungs so the worst cases end up having to go on respirators in ICU.  This quickly overwhelms the medical system and once that happens mortality rates go way up.   

Add into that we have no built up immunity to it yet and no proven treatments for it or vaccines against it.  All that means it will pretty much run wild this year.  Cures and vaccines take time to develop and even more time to test.  So it will be at best months before they are available.  By the time round two of this comes around we will be in better shape.  Some natural immunity will have developed.  Cures that can keep many cases from going critical will be around.  And vaccines likely will have been developed.  If enough people have taken these then the spread can more easily be contained.

We are still staying in, Pete's been in for 14 days.  I've been out twice to grocery store.  Sitting on the deck a lot and doing some odd tasks around the house.  I'm grateful during times like this that Pete and I like each other a lot :-)

I try to avoid the daily briefing etc... they only serve to give me anxiety and strangely enough I've never been an anxious person. 
I guess thinking of death and dying there is only so much I can take.

I hope everyone is doing as well as you can.

Pete is outside quarantine gaming.  What an age to live in!
