Not true, Kevin07. If you studied biology and microbiology in college, you would learn all about these little critters: both the good and the bad. I was a microbiology tech for years when I worked. Besides learning a ton of Latin names of many species, you know everything that’s known about them, including the fact that every few years, their names change. Example: Pasteurella pestis to Yersinia pestis. This is the causative agent for bubonic plague.

I have a gastro virus right now, literally feels like dying, but I know there is a war inside of me. I am so proud of my little soldiers that keep this virus at bay within 24h, but why don't they learn??? I get that gastro virus every year !!
Get your gut microbiome tested? A healthy one would decrease your chances of getting a stomach bug by a significant amount. Sometimes food sensitivities can also make you more likely to get a stomach bug, so that's another thing you might consider to get tested for and eliminate from your diet.
Viruses also mutate, so your likely not getting the exact same virus every year. Every time you get the virus it will be different than the last time you got it and your immune system will be starting from scratch. Hence your getting sick every time
I remember in a video on COVID there was mention of basically 'viral niches', where different viruses might specialize towards different tissues (like lungs vs throat for respiratory diseases), and with benign viruses in the body I wonder if any of them provide some buffer against new viruses by occupying a viral niche. May be more likely in the digestive system if the virome is essentially a pair to gut bacteria, but idk, it's an interesting thought
I like this idea. I think it leads into the idea as well that the virome can contribute to priming of immune systems almost like a natural vaccination. Like if you have a virus that mostly infects epithelial gut cells with a slow reproductive rate and doesn’t cause significant damage, that can leak into lymph or blood, but is harmless and killed, but closely related to a deadly blood borne pathogen sharing viral epitopes. It could then prime the immune systems response to an infection from a more pathogenic virus that could infect lungs etc.
That's a really interesting idea! And very possibly true. I've been sick from something unknown for most of my life. I thought for sure that COVID would kill me if I got it. But it didn't. It didn't get all that bad for me. I wonder if my resident virus, or whatever it is, was already taking up that niche. Or what if my resident virus actually fought of the COVID 19 virus for me??? You know, didn't want to share it's space with another really bad virus. How's that for a crazy idea!? Maybe my lifelong illness actually saved my life!
That was what I was thinking as well, it does sound temptingly obvious since this tends to apply in almost all of biology but I think to be sure you'd have to actually prove that viruses can exclude each other, since like with how many cells we have it's not like there's ever a lack of cells for viruses to infect.
It's always seemed to me like the most intuitive way to view a virus is to consider the infected cell to be the mature organism and the virion to be a spore or predatory gamete.

@@louisfalcone5494 I mean why? Animals being tested for diseases do that our species can live has no moral consequence really. I mean every animal on earth would probably do the same. We are at the end of the day animals like any other. Also animals benefit from testing as well. You have to test in order to get medication for animals. Apparently you are just anti life though. Which is fine, but realize most people don’t value other species over their own species because of the way we evolved.
The fact that viruses exist in such numbers and for so long, means that they are essential and have a reason to be here and apparently everywhere. Rarely have we found that something that is everywhere is not an integral part of nature. Understanding their significance, function and evolution is going to be important to everyone.

How would we know they stretched that far, since they are microscopic? For that matter, how do we know there isn't already a "chain" of viruses that help new viruses invade?
@@steveipsen6293 If you know the approximate amount of viruses in the ocean, and the approximate length of a virus then you can determine how far it would reach if laid down end-to-end. Works for any object, microscopic or not. In this case, according to "Marine viruses - major players in the global ecosystem" by Curtis A. Suttle, they estimated there are 10^30 viruses in the ocean. And viruses vary in length from 20 nm to 500 nm. If we take even the smallest virus at 20 nm and multiply that with 10^30, we get 2x10^31 nm which is equal to 2,114,002 light years.
@@steveipsen6293 Well, they are small but according to a quick google search there are approximately 1x10^31 viruses on earth, and they range from a few micrometers to a few hundred micrometers. At the most conservative estimate that would mean they would stretch 5,285,117.5 light years across if laid end to end. That's not taking into account anything larger than 5nm.
One paper I found fascinating is "Viruses and cells intertwined since the dawn of evolution". In it they hypothesize that Archaea, Bacteria and Eukarya are the results of a DNA virus infecting an RNA cell on 3 separate occasions. If that is the case, then viruses really have been central to the history of life on Earth.
‘Eliminate all human pathogens’ is still a really dangerous wish. Some microbes are harmful in one context and helpful in others. Eradicating absolutely everything that can be dangerous if it gets into a wound or lung or whatever could be crippling to the organ it usually resides in or on.
But! If you include all eukaryotes in that, you could have the unintended consequence of certain animals reproducing uncontrollably without natural viral infections to control their population, and we know where that leads

Viruses are in our bodies and actually help us from becoming ill and they are about the same size as exosomes and those definitely help us Dr Sam Bailey MD and MD research youtube also
I was waiting throughout the video (and fascinated by the mentions of the virome, virions, and the effect on the carbon cycle) for the "all animals have viral DNA *in their own genomes*, and it's proved to be beneficial for us" bit to be mentioned! Not to mention, the effects of viral plagues on human history - there's been a *big* role played by those.
i have a seperate hypothesis - viruses arose as defence method. for instance, bacteriophages being made by an organism that is preyed upon by certain bacteria. perhaps that organism that originally evolved to produce bacteriophages now died out or lost the ability to make bacteriophages
Notes: Two hypotheses on how viruses came to be- 1 - Progressive Hypothesis - Pieces of DNA and RNA learned to jump between cells. 2 - Regressive Hypothesis - Viruses are remains of cells that somewhere in the past lost their cellular casing and thus had to parasitize other cells in order to survive & proliferate. 3 - In a third scenario, viruses arose through multiple scenarios.
There was this question in the book what if where if you gathered all the viruses in the world in one pile, it would be 225 million cubic meters, the size of a small mountain.
I remember hearing (might have been from this channel) that bacteria can't be both virus resistant and antibiotic resistant, so not having viruses would possibly lead to harder to kill bacteria
Every natural part of our ecosystem has a role, sometimes we just happen to be a factor in that role. Scientists do their best to negate the damage done by these events but it is ultimately up to us how much we will be involved. With Covid, people decided to ignore all of the advice given. That is why we are all still in this situation.
"Most viruses don't mess with us at all", but eliminating all human pathenogenic ones just creates an empty niche for new ones to move into. So it's wish away all of them or none of them.
Any Dungeons and Dragons player or dungeon master would tell you to be careful what you wish for. When you make a wish, make sure your wording is carefully crafted to avoid getting screwed over. An example of such: "I wish that all harmful viruses which infect humans would stop infecting humans." Alternatively, if you're slightly more selfish: "I wish for the ability to cure disease as an at-will touch power."
I've had this idea about viruses for a while now, viruses being some sort of DNA making machine that caused evolution etc., I'm glad to have found this video. The "error"/ virus in the order causes creation. The sacred duality of nature and in the cosmos
Just a headscratcher: I know viral DNA integrates itself into host DNA and can be actively repurposing the cell there or be dormant for generations. Now here's my take: what if (some)viruses are originally made by the DNA as an early sort of cooperation (original parts of the cell's evolutionary track). Viruses as a sort of automated turret a cell could make to keep itself safe in dangerous surroundings (If you require a metaphore an aircraftcarrier where the planes have to come back to the cell to recharge/multiply). Then at one point some of those virusses got a mutation allowing them to overtake the whole celulair machinery, instead of an allocated amount of the mothercell, causing it to kill it`s host. A very early attempt at numerical safety where cells didn`t have had anything like that before. Just a thought
Those are called cytokines. Secreted by some immune cells, B cells secrete immunoglobulins. Most likely a prion, self replicating protein. Evolved into a virus then a bacteria
My first thought after watching this was 'What if we could create a virus that infected the plaque in our mouths so we don't get cavities or have stinky breath anymore?'
As a general rule, if you come across a magical, wish granting creature, such as a genii, for the love, don't wish for anything! Genii are are jerks and will more than likely screw you royally with whatever you wish for.
The modern view of viruses remind me of school and learning of endospores. They carry everything necessary to make a new cell, but aren’t technically alive. When conditions become favorable they become viable and form a new bacterium. Of course, endospores are not parasitic, but it reminded me of them.
I have a Hank aimed question: When people colonize places outside of earth, would we be making a decision to sort of make this weird genie wish a reality by choosing what viruses we brought with us? Thank you for SciShow!
There's a limit on how much we can choose that, assuming any organism from Earth goes to this new place. As he said, we're full of viruses already. Those existing viruses would keep evolving in ways we couldn't predict. We could choose not to bring anyone actively infected with certain known viruses, but even those might make it through under the radar.
Now I'm thinking of a story with an alien planet where viruses never evolved so the kind of symmetry and biological organization they have is so different.
My mind immediately thought of bacteriophages and how we'd all probably die from bacterial infections without viruses to hunt them down

Just wanna let you know Hank, that I’m here after the shout-out to this vid in your tik tok 🐒💨
#justiceforSciShow
I was waiting throughout the video (and fascinated by the mentions of the virome, virions, and the effect on the carbon cycle) for the "all animals have viral DNA *in their own genomes*, and it's proved to be beneficial for us" bit to be mentioned!
Not to mention, the effects of viral plagues on human history - there's been a *big* role played by those.
"There's a universe now."
"What's it made of?"

i have a seperate hypothesis - viruses arose as defence method. for instance, bacteriophages being made by an organism that is preyed upon by certain bacteria. perhaps that organism that originally evolved to produce bacteriophages now died out or lost the ability to make bacteriophages
Clicking on this thinking "I know I want all viruses gone, but go ahead and change my mind"
Welcome fellow 2%
Notes: Two hypotheses on how viruses came to be-
1 - Progressive Hypothesis - Pieces of DNA and RNA learned to jump between cells.
2 - Regressive Hypothesis - Viruses are remains of cells that somewhere in the past lost their cellular casing and thus had to parasitize other cells in order to survive & proliferate.
3 - In a third scenario, viruses arose through multiple scenarios.
I'm here to be the cool 2% mentioned in Hanks TikTok about this topic.
I'm less than a minute into the video, and already the premise has me thinking that SOMEBODY has been watching a lot of Kurzgesagt lately. XD
Hank, I’m here from TikTok! 2%!
There was this question in the book what if where if you gathered all the viruses in the world in one pile, it would be 225 million cubic meters, the size of a small mountain.
I remember hearing (might have been from this channel) that bacteria can't be both virus resistant and antibiotic resistant, so not having viruses would possibly lead to harder to kill bacteria
this is one of the best videos Sci Show has made many thanks !
Every natural part of our ecosystem has a role, sometimes we just happen to be a factor in that role. Scientists do their best to negate the damage done by these events but it is ultimately up to us how much we will be involved. With Covid, people decided to ignore all of the advice given. That is why we are all still in this situation.
This was great! Hank should get on TikTok too.
One of the best episodes ever!
No matter what we do, there will be impact, usually in ways we had not foreseen. This is great Hank.
Viruses: *Are deleted and forbidden to spawn*
Half of all "Free Downloads": Adios
"Most viruses don't mess with us at all", but eliminating all human pathenogenic ones just creates an empty niche for new ones to move into. So it's wish away all of them or none of them.
Here to be part of Hank's 2%
Here from TikTok?! Had to watch the full video!
I'm part of the 2%
Wow that was well said Hank!
I wish all Viruses on this planet would disappear..
Genie: Your wish has been granted.
*ALL HUMAN LIFE ON EARTH DISAPPEARS*
Earth: Ahh much better now
Kudos to your writers. Well said .
Thanks for acknowledging them!
Anybody here as the 2% from Hank's TikTok?
hiiiiii
This is so cool, leaves me with so many questions, thank you for sparking curiosity
So. Message received, Worship Nurgle.
It's nice to live in the day and age where you can ask random questions and somebody made a video about it
Any Dungeons and Dragons player or dungeon master would tell you to be careful what you wish for.
When you make a wish, make sure your wording is carefully crafted to avoid getting screwed over.
An example of such: "I wish that all harmful viruses which infect humans would stop infecting humans."
Alternatively, if you're slightly more selfish: "I wish for the ability to cure disease as an at-will touch power."

No matter what you may wish for, everything has unintended or unexpected consequences. It's foolish to mess with God's plan.
@@iramsavir5631 As far as D&D is concerned, that's part of the fun.
@@AvangionQ Yeah, messing with God is fun.
This was so good thank you
Team 2% 🤙🏽
People saying wishing for all virus to dissappear, but why can't we all just wish for bad viruses to dissappear
Maybe just wish to get rid of the chance for viruses to become deadly wouldn’t get rid of what we’ve got but it’d be better for the future
Wow, this is amazing!!!
I learned so much new information!!
Thank you so much!!!
I've had this idea about viruses for a while now, viruses being some sort of DNA making machine that caused evolution etc., I'm glad to have found this video.
The "error"/ virus in the order causes creation. The sacred duality of nature and in the cosmos
Well it played a significant role in evolution but it's a huge stretch to suggest it caused it with substantial evidence.
I like how this video is a PSA for wish grantees
here because hank’s tiktok
Oh I like this format! It’s why I enjoy Kurtzgezagt! What if!
Is there an argument anywhere in the scientific community about whether sperm cells should be considered virions?
Part of the 2% check
Just a headscratcher:
I know viral DNA integrates itself into host DNA and can be actively repurposing the cell there or be dormant for generations.
Now here's my take: what if (some)viruses are originally made by the DNA as an early sort of cooperation (original parts of the cell's evolutionary track).
Viruses as a sort of automated turret a cell could make to keep itself safe in dangerous surroundings (If you require a metaphore an aircraftcarrier where the planes have to come back to the cell to recharge/multiply).
Then at one point some of those virusses got a mutation allowing them to overtake the whole celulair machinery, instead of an allocated amount of the mothercell, causing it to kill it`s host.
A very early attempt at numerical safety where cells didn`t have had anything like that before.
Just a thought
Those are called cytokines. Secreted by some immune cells, B cells secrete immunoglobulins. Most likely a prion, self replicating protein. Evolved into a virus then a bacteria
Sounds like the complement system.
Viruses are another forms, and probably a lot more ancient. Always a treat to see Hank.
Here to learn! … And to be in the 2% of viewers brought here by tik tok! 😊
Yay! Same
Well for one, my parents wouldnt have to buy a new computer every year...
hank am i amazing now?
WOW! Thanks for this :)
I like this idea of a show. Science: What If......
That title genuinely freaked me out to think of. Surely this won’t be good. How much of me disappears?!?
My first thought after watching this was 'What if we could create a virus that infected the plaque in our mouths so we don't get cavities or have stinky breath anymore?'
Imagine if life started as viruses. You'd be wishing away all life
Depends on quantitative definition though.
As a general rule, if you come across a magical, wish granting creature, such as a genii, for the love, don't wish for anything! Genii are are jerks and will more than likely screw you royally with whatever you wish for.
Or a monkey"s paw...
I wish for $5.75
what if i wish for a long and fulfilling relationship with the genie?
The modern view of viruses remind me of school and learning of endospores. They carry everything necessary to make a new cell, but aren’t technically alive. When conditions become favorable they become viable and form a new bacterium. Of course, endospores are not parasitic, but it reminded me of them.
I have a Hank aimed question: When people colonize places outside of earth, would we be making a decision to sort of make this weird genie wish a reality by choosing what viruses we brought with us?
Thank you for SciShow!
What about viruses present on the planet you choose 😲😲
@@src3360 cry about space aids I guess
@@src3360 why would there be space virus if space has nothing for virus to infect (at least as far as we know)
There's a limit on how much we can choose that, assuming any organism from Earth goes to this new place. As he said, we're full of viruses already. Those existing viruses would keep evolving in ways we couldn't predict. We could choose not to bring anyone actively infected with certain known viruses, but even those might make it through under the radar.
There have been folks at NASA wrestling with this question for at least two decades, probably longer. No real answers yet, AFAIK.
Okay but Virion is a fantasy name right. It's like some elf dude.
Here purely out of spite
I like to think of viruses as self replicating messengers.
Now I'm thinking of a story with an alien planet where viruses never evolved so the kind of symmetry and biological organization they have is so different.
I'll be fine just wishing all mosquitoes away.
