Coronaviruses | Discovery, Origins & Symptoms of COVID-19, SARS, MERS and Other Coronaviruses

Overview of Coronaviruses That Cause Disease in Humans (COVID-19, SARS, MERS and Other Coronaviruses), including their discovery, origins, diseases caused by each, virus types and lineages, and basic reproduction numbers
In this lesson, we discuss all of the coronaviruses known to cause disease in humans, including HCoV viruses (ex. HCoV-229E) and the newer coronaviruses (like MERS-CoV and SARS-CoV-2, which causes COVID-19), when each of the viruses was discovered, possible origins, diseases caused by each, virus types and lineages, and basic reproduction numbers.
I hope you find this lesson helpful and informative. If you do, please give this video a thumbs up, and subscribe to support this channel and stay up-to-date on future lessons.

IMPORTANT UPDATE: Hi everyone. As many have commented, the hypothesis of the origin of SARS-CoV-2 mentioned in this video is outdated and highly likely to be incorrect. At the time of recording this lesson (April 2020), what was mentioned in this lesson was the prevailing hypothesis. But as time has gone on, new evidence has emerged, and this is NOT the prevailing hypothesis at present. So, please disregard what is mentioned here for the possible origin of SARS-CoV-2. The reproductive number and mortality rate of SARS-CoV-2 is likely different (due to different variants) than what is presented here as well. Other information is accurate. If there is any other information that is incorrect, please let me know. Thanks - I hope you all find this lesson helpful and informative, and my apologies for not providing an update sooner. JJ.

Viewed not even a Thousand times, over a thousand times less than a video called "Ps5 specs reveal"! And there are other countless examples so good to know that most people know what to priorotize these days and where their interests lie!

I would like to know more about coronaviruses, can you tell me the source of the content of this video, please? And thank you for your videos!

[@daanya3747]

You have an outstanding way of teaching. Very interesting and well explained.

[@tegf4]

My question Did the virus come from the animals naturally or was it taken and made ?

[@mirossopower6462]

Naturally if you eat an infected animal which is not cooked the right meaning almost raw meat not enough heat you get the same infection and you infect ppl around you

@@mirossopower6462 i heard it was an accident in a Chinese lab , idk if thts true, reminds me of a zombie apocalypse

[@pawelhladkiewicz8250]

Any info on similarities between OC43 and SARS-CoV-2 S and N proteins? I'm digging why do parents of young children (below 5yo) tend not to have any symptoms of COVID-19 or not even catch it at all (like they would have some NK, CD4 or CD8 lymphocytes that destroy the virus before it can even attach).

[@johnwireman2660]

Great job on all the human coronaviruses. There’s just one aspect about OC43 I was hoping you’d touch on. It has been molecularly dated to 1890. That’s very close to when the 1889 Russian flu pandemic started. There’s a good chance it was caused by OC43 instead of influenza.

[@sneakypress]

When you said, ‘these coronaviruses were discovered in the laboratory, Netherlands, Maryland USA, etc.’ , what EXACTLY do you mean ?

[@cellocreamstrawberry]

I’m thinking the same thing, have you found what it means?

[@SanjibDas-qm4eh]

Nicely explained,,, keep it up

[@robbob1693]

Are all Flu type viruses ph sensitive.

[@kingofkards1110]

Quick question how many coronavirus in total including the ones that infect animals, is it 32 in total or is it still 7 ?

[@ferolcat2009]

I dread to think if a SARS-CoV-3 ever emerges, especially if it follows the trend of being more prevalent and deadly.

[@jonnyxyz1234]

SARS COV 2 come 2012 from Bats to 6 Coppermine worker.

[@mitchconner2021]

As someone who probably has the virus take it seriously. It's not something to mess with.

[@spookymulder945]

I know two people that have it. And their son got it too. And this is in a small town.

[@vatisbad]

Can u tell me how many times did 1st coronavirus that came in 1960s mutate ?

[@anotherpointofview222]

I think virus mutate continuously. No virus replicates without ever a mistake being made.

[@lukeuzzellbryan3883]

Belief is religion

[@anotherpointofview222]

Belief isn't a religion. Believing is the decision you make to accept something as true. You can believe anything presented to you. A lie can be believed just as easy as the truth. Belief is what you accepted as true. Religions hold certain beliefs. Science does too. Don't equate beliefs with religion. That's what most people do. Try and pretend or give the impression that science has beliefs too. Based on known facts, most time. They come to conclusions that are nothing more than beliefs. Not much different than religion, which may not have known verifiable facts.

[@mitchconner2021]

What causes viruses to get worse during different times of the year?

[@hasso9]

its unknown, but you can look up the theories scientists have come up with

[@Novak2611]

There's a lot of theories and combination of these theories: -Virus membrane is stable in cold and dry weather and get damaged with heat. -People in cold weather tend to stay indoors which increases transmission -UV lights kills the virus which is absent in cold weathers. -UV light also make the body produce Vitamin D which regulates immunity to respond to viruses

You should probably update this video. If you’re wrong about SARS CoV2 origination and develop into CoV-19 how can this video presentation be trusted? You got to remember KZbin tends to be a trustworthy source for many, and many of these people do not dig for factual and truthful information sources or have no other real options for their information

Is it MERS?

[@kittylovers6410]

Is there any open beta corona virus?

[@valeriesanchez3074]

the mortality rate of SARS-CoV-2 is lower (3.4%) than that of SARS-CoV (9.6%) and MERS (35%)

[@koki10190]

SARS MERS covid-19? dosent makes sense it does but if it was COVID maybe itll be in name idk how to explain but u know what im talking about

[@zachthekaoticsavage4668]

Middle eastern respiratory syndrome is a coronavirus strain.. And it has a much worse fatality rate than covid19 which has a fatality rate of 0.23% if not less by now... Technically with the coronaviruses we have hit herd immunity due to the coronaviruses that have circulated the world populations for decades

[@Dragontamer135]

I hope this teaches the Chinese to stop selling Pangolin meat, bat meat and other stuff like that.

[@teddybearyorkies1358]

That was the theory that was being promoted at the time. It’s now looked at as a lab leak - not zoonotic (animal to human).
