In the Last Two Decades – SARS, MERS, and COVID-19

Humans have been afflicted by a series of coronaviruses in additon to deadly flu strains.

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.

SARS was designated SARS-CoV-2 . MERS was designated CoV.

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 image a 1/3 death rate!

CORONAVIRUS

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 aflicted over 60 million people in the United States.

The COVID-19 is not in that category.

The swine flu  hit the 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
This is a pangolin

These are pangolins rescued from poachers. They are a luxury ingredient in Chinese and Philipine medicinal potions.

In 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 searching for the culprit.

Thanks for stopping.
