SARS MERS AND CORONAVIRUS

In the last two decades, the planet has been assailed by coronaviruses.

This is an image of a coronavirus cell. To be precise it is the COVID-19 that is afflicting us in 2020.

I was reading the news on my phone.

That lead me to write this.
It appears that violence and harassment are increasing as the COVID-19 pandemic deepens.
The violence against immigrants is particularly distressing.
Bigotry and fear are no excuse for behaving like jackasses — and worse.
If you want to know why read this.

SARS

Many of you have heard of SARS, a viral infection before COVID-19 which we are suffering through right now.
The SARS pandemic ran from 2002 to 2004.
The outbreak originated in Foshan, China and infected over 8,000 people and caused 774 deaths worldwide.

MERS

Since SARS there has been MERS.
It too was a coronavirus.
Mortality was about one-third of diagnosed cases.
Camels have been shown to have antibodies but there is no scientific proof of how they got infected or how it spread to humans.
It’s spread outside of a hospital is rare.
But imagine a 1/3 death rate!
MERS one-third morbidity rate!
Timeline of the MERS pandemic. It killed 1/3 of the infected population.

CORONAVIRUS

Why are they called coronaviruses?

H1N1

SARS was mainly in the East and MERS in Saudi Arabia and the East.
The most recent pandemic to affect the United States was the H1N1 “swine flu”. In 2009 it afflicted over 60 million people in the United States.
The COVID-19 is not in that category.
Swine flu hit younger people hard. I remember standing in line with my sons waiting to get the vaccination shot.

Here we are

Another coronavirus. Where do they come from?

Pangolins

This is a pangolin
These are pangolins rescued from poachers. They are a luxury ingredient in Chinese and Philippine medicinal potions.

n February 2020 Chinese researchers identified that Pangolins match 98 percent of the cells in the COVID-19 virus.
Later the number was rechecked and it dropped to 90.3%.
Scientists will have to search for the culprit.
Thanks for stopping.

Coronaviruses A Constant Battle in a Two Decade War Continues

Coronaviruses A Constant Battle in a  Two Decade War Continues

Mar 16 · 5 min read
Now the battle is once again joined.
Humans against the virus.
The novel coronavirus SARS-CoV-2 which causes the disease COVID-19 is running rampant across the globe.
So far Italy is the hardest hit European country but they took decisive action last week that may start slowing down the disease.
This is the headline in The New York on March 13, 2020 — last Friday.
The model these writers, Nicholas Kristof and Stuart A. Thompson were using last Friday was very alarming.

“If we stay on the current track, this model predicts that roughly a third of Americans — more than 100 million people — could become infected.”
It also indicates that more than 9 million will be infected at any given time.
Deaths? One million could die.
Other estimates are higher — up to two-thirds could get sick.

Interventions

Interventions will have a dramatic effect. Close down the schools, large gatherings, and initiate mass testing so that experts can predict where and when the virus will strengthen.
Unfortunately as of last weekend, enough test kits were still weeks from being delivered.
Shifting the interventions to one month later means that more TWO MILLION will be infected.

Speed

SPEED is of the essence.
Did we act as fast as we should have? No!
Did we act decisively — shutting down NOW?
Acting today instead of tomorrow will matter greatly. We will have to see what the next few weeks bring.
Now we will have to see if we acted aggressively enough.
Can you imagine what our health care system will look like when over one million people are infected at one time?
The government must start setting up emergency shelters outside of current emergency rooms this week. By next week we will need them!
The numbers are there. He did an excellent job of making sure that an accurate case is presented and there is no wiggle room for our politicians and administrations to snark their way out of the coming crisis.
I recommend that you go to The New York Times using this link and you work the interactive chart they have and determine for yourself what scenario you think is going to play out.

On Friday, January 10, 2020, scientists from around the world finally succeeded in prodding the Chinese to share their knowledge of the virus.
CEPI (Coalition for Epidemic Preparedness Innovations) awarded $9 million to each of three companies to make a vaccine. Inovio, Moderna and the University of Queensland in Australia.
My next post will be on how these life-saving vaccines are made.
On another scary front, an article in Live Science caught my attention.

SARS

The headline reads “New coronavirus may spread as an airborne aerosol, like SARS.” The article was written by @Nicoletta Lanese a few days ago.
In February researches found that the SARS-CoV-2 virus, which is the precursor to the infection COVID-19 can survive the air for several hours.
Why?
Because it is expelled from humans carrying the virus in fine particles known as aerosols.
“This coronavirus (SARS) can be detected up to 3 hours after aerosolization and can infect cells throughout that time”.
SARS virus mingled with human cells
SARS virus cells intermingled with human cells
This study was posted on March 10, 2020, but has not undergone extensive peer review. The study was updated on March 13, 2020.
Several questions remain. The co-author of the study Dylan Morris is a graduate student at Princeton University.
He tested the aerosols on cells in a lab, not on humans subjects.
It is unlikely that these aerosols are involved in the COVID-19 even though the SARS-CoV-2 is the respiratory infection of COVID-19.
In COVID-19, the respiratory infectious cells are expelled in droplets that fall to the ground rather than through the air.
This is why doctors came out with the guidance that the paper masks everyone was wearing are not necessary. Normally a person does not “breathe in” the infections since they are not suspended in the air.
They recommend the N95 respirator mask.
N95 respirator masks that appear considerable more expensive that the paper ones.
It appears these masks are considerably more expensive than the paper ones.
Thank you for stopping.
As I mentioned I will look at how vaccines are made in the next post since we are all waiting for them. I would add breathlessly but that would be a very bad pun.
