A couple friends posted this on Facebook talking about the virus. I now understand why this is so not just the plain flu and why it needs to be taken really serious.
Feeling confused as to why Coronavirus is a bigger deal than Seasonal flu? Here it is in a nutshell. I hope this helps.
It has to do with RNA sequencing.... I.e. genetics.
Seasonal flu is an “all human virus”. 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 it’s a problem, Why? Because we have no natural or
acquired immunity.. the RNA sequencing of the genes inside the virus
isn’t human, and the human immune system doesn’t recognize it so, we
can’t fight it off.
Now.... sometimes, the mutation only allows
transfer from animal to human, for years it’s 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 it’s gonna be..
H1N1 was deadly....but it did not mutate in a way that was as deadly as
the Spanish flu. It’s 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, “slippery”
This
Coronavirus, not being in any form a “human” 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..
That’s why Coronavirus is
different from seasonal flu, or H1N1 or any other type of influenza....
this one is slippery. And it’s a lung eater...And, it’s 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 it’s 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.
