A friend sent this to me so I thought I would share:
THIS, folks, is the simplest explanation of why the coronavirus is so deadly, and why the response has been so extreme. Instead of raising conspiracy theories, blaming ethnic groups or political parties, or violating the requests that we remain as isolated as possible because, you know, it's just the government's way of taking over society and controlling us -- EDUCATE YOURSELF. Start right HERE. (Kudos to my friend Mark Knox for copying and sharing this post.)

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 don’t understand...

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 World Health Organization (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, that's what decides how contagious -- and 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 to now.

Along comes this coronavirus. It existed in animals only (for nobody knows how long) ... until 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 use the term “slippery” to describe a virus that develops this quick ability.

This coronavirus, not being in any form a “human” virus (whereas we would all have at least SOME natural or acquired immunity) took off like a rocket. And this was because humans have no known immunity to it. This means doctors have no known medicines to treat it.

I repeat: Right now, doctors have NO WAY to treat this virus. Nothing. Nada. Antibiotics don't work because coronavirus is viral, not bacterial. The only thing we can do at this point is ease some of the symptoms ... giving fluids, meds to reduce fever, and supplemental oxygen.

It just so happens that this particular mutated animal virus changed itself in such a 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 as hell. And it’s a lung eater. And, it’s already mutated AGAIN, so that we now have TWO STRAINS to deal with already -- strain s and strain L -- which makes it twice as hard to develop a vaccine.

We really have no tools in our shed to deal with this. History has shown that fast and immediate closings of public places has helped in past pandemics. (Philadelphia and Baltimore were reluctant to close events in 1918 -- and they were the hardest hit in the U.S. with the Spanish flu.)

Here's an interesting historical fact: Henry VIII stayed in his room, and allowed no one near him until the Black Plague passed. (Honestly ... I feel like I understand him so much better now). He had no medical technology back then. The ONLY tool he had in his shed was social isolation. Today, even with all our medical technology, that same tool is the ONLY one available to us right now, until this virus can be figured out and a vaccine can be developed. To ignore this tool is to put countless people -- including ourselves -- at risk. (And let me add that, right now, it’s hitting older folks harder.)

What's also scary is this: This genome is so slippery that, when it mutates again -- and it will -- there's no telling what it will do next.

Be smart, folks. Acting like you’re unafraid is so not sexy right now.

Stay home if you can, folks -- and share this with those who just are not "getting it."

You can blame third world food handling practices and totalitarian govt. secrecy. When has one of these animal to human mutations started in this country?

Virologists studying COVID-19 have already stated that surprisingly it hasn't mutated at all since infecting humans, its become quite stable so there's no certainty that it will mutate again.

Thanks for sharing I’m one who is very high risk and wife had double pneumonia this winter and hasn’t fully recovered from that., it is very serious for some of us,
