- Poliomyelitis is a disease caused by the poliovirus, which has the ability to infect motor neurons in the spinal cord and cause paralysis. American President Franklin Roosevelt was famously crippled by polio. The poliovirus exists in a few different serotypes, which belong to the genus enterovirus and the family picornaviridae. How do they spread, and what are the other symptoms? Is this disease still a concern? Let's take a look.

I was led to this from the story of Paul Alexander lawyer and last of Polio survivor who lives in an iron long.
Same. I did some wiki research before coming to this video though. Professor Dave sure clarified all doubts though.

I contracted Polio in 1979 when I was 2 years old in rural South Africa. Today I walk with a pronounced limb as the virus devastated my left leg' s pulling and lifting muscles. Life changing as this might be- I am thankful I am alive and feel lucky
That’s unimaginable. You’re only 5 years older than my mother, and I wouldn’t be able to bear the sight of someone I care for in such a condition. I sincerely bless you a long and happy life. ❤️ Thank you for sharing.
Did you live?
@@Elnegro.. they wrote this comment so I’m guessing they are alive
@@Elnegro.. He passed away = covid
@@Cheesling Did not say he was vaxed either probably why he survived.
i cant wish the iron lung even on my worst enemies
I agree. For my enemies, I withhold it. :)
Wow you guys got a heart,cause i would wish my enemies would get polio
@Rob Cas You really took that personal. Are you one of his enemies?
@Rob Cas How old are you that you don't understand how people get enimies? Stop having tantrums for no reasons and go drink your bottle.
@Rob Cas And you're still mad for no reason. Life must suck for you but it might get better in 2021, hang in there.
I was born just before US polio vaccine approval (1952) during the epidemic. My mother was a nurse at a major metropolitan hospital and terrified for me. A very dark time. Luckily, I didn't get it, or the severe form, anyway. We used to be given the shot, then oral vaccine, at school. Enormous effort. No anti-vaxxers then, as people knew firsthand the tragic nature of these outbreaks, and not spoiled descendants who benefited from enormous public healthcare vaccination initiatives.
@Ritz Girl Gamer nah he around 75
hes 69 😳
The polio vaccine was approved in 1955.
@Kallbasa Over half a million deaths in the U.S. from Corona, and not all "Old grannys"
@Kallbasa Ignorance is bliss? People who were young and in relatively good shape have died from Covid.
I knew so little about Polio prior to watching this video, so thanks for making this! I appreciate it :)
Wow, Dave-- you know a lot about the science stuff! Thanks for explaining it, professor!
Hi our boss is so funny and I want you to stop it
@@Aslaygirl124 huh
Question about minecraft and how to you a better place grade 😁I know I am a little confused as I have been trying for the last few weeks to make sure that you have a new job in your office so that I may have some more than a couple more hours of sleep and then a little bit more of the day and then a few minutes ago and it is still on.
Professor Dave explains
Naw hes just following the books... Vaccines are immunosuppresive.
July 2022: I believe the type of polio recently found in a 20 year old man in New York was analysed and found to be the strain of polio given in the oral vaccine. The infected patient was not vaccinated for polio. He had recently visited Poland and another European country. I wish this video stressed the importance of hand washing, since the disease is spread from fecal matter.
Yes, that was vaccine derived, which is where all current polio cases and outbreaks have come from since 1993 *according to the World Health Organization*
It's also been detected in London as well !
@@zachocracy wait, new cases are coming from the vaccine?
@@danielledegeorge2129 yes, opv
A fascinating all too brief video sir. Thank you. I wonder if it is possible to give a little more detail about what the virus does to the neuron that results in signs and symptoms please?
Blessings and peace

antivaxers: allow us to introduce our selves
Could ya stop with that term.. It's only used by the media to misrepresent genuine criticisms of vaccines. I've never met or spoke to anyone who doesn't believe vaccines work
@@mitchelrowe6915 Then you haven't been paying attention. There are a lot of people who genuinly will not allow themselves and their kids to get any vacinations. It is thanks to that ever growing! group that measles and rubela are making combacks in the western world. The whole thing pretty much started by Andrew Wakefields bogus paper where he claimed measels vaccines caused autism. This paper has since been proven to be incorrect (multiple times) and Wakefield has had his licence pulled. Unfortionately, the anti-vax community sees that as proof that he was on to something and that big pharma tries to silence him.
As with any conspiracy, it's people who think 10 min on google and a few hours on facebook and youtube gives them more education then 6 to 8 years of medical school and a decades long career in medicine. I wish I was exagerating that btw. Quite a few of these people genuinly think doctors get their information during their studies from the same youtube videos they see.
The problem, I think, is in education costing money and being available in limited amounts, where bullshit is free in unlimited amounts.
@@mitchelrowe6915 you'll be surprised if you find out that there are tons of them around
@@roepi I'm not saying they don't exist I'm saying that I don't know a single person who thinks that way because they are not that common. Anti vaxxer is a term thrown around to make people with genuine criticism for the vaccine thrown under the same umbrella as people who don't think vaccines work
@@mitchelrowe6915 And what would you call genuine criticism? So far the vast majority of criticism I found on any vaccines (inlcuding the various covid ones) have no basis at all. They are just copy pasting crap others have been copy pasting from either con artists and/or attention whores. Worse even, these people collectively refuse to listen to any counter points even when you can show the origins of their concerns come from proven fakery. For some reason people these days think that because they can google things, they suddenly know at least as much about a subject as the experts who not only spent years to get a ph.d in the subject but then spent decades on research. I've come across people who genuinly think the experts get their information from the same google searches they do. Somehow, these people think they managed to find information the experts missed in their decades of work instead of assuming that maybe, just maybe, those experts actually know something they don't. Worse even then that: they are getting louder and more fanatical in my observation. They don't even fear using bombs anymore.
As far as the 'not that common' part: I wish you were right on that. Sadly they aren't uncommon and their numbers are growing rapidly thanks to the amount of con artists and attention whores who flood the internet with so much bullshit that it has become so unavoidable that you need a very good bullshit radar to see through it (and most people realy suck at that bit). Add to that all the people who believe only those scientific results they can fit into their own world view and automatically reject all others and you have a pretty dangerous situation. There is a good reason a lot of diseases that haven't been a problem for decades are making rapid combacks.
Hi, great video... question... did/can pill affect just one limb? Say, just an arm? Or did it always affect an arm and leg? Thanks!
we learn together, thank you Prof. Dave👍
Dave you have a voice I can listen to. Sounds a bit strange that I know but the information is given at a good speed, with good detail and I just.... Like your voice. Lol so I subscribed. 😎
very helpful! I need to learn a bit of this for my History exam
Learned alot. Very well done. Thanx !
👍❤🇨🇦
The reflection is: in 2020 with advances in neurology, particularly knowledge about motor units and applications of electrical stimulations, can muscle tissue be stimulated to regain muscle mass? On the basis that certain electrical current can stimulate the nervous system, and that neural cells may reproduce if stimulated, it would be interesting to know the current state of the art on possible recovery of destroyed/impaired neural connections.
G C - Let me tell you a story. It is a true story, but the words used are simplified: A long time ago a motor unit and a motor neuron had a great friendship. They talked on the telephone every day. The motor neuron would ask the motor unit to dance, and the motor unit would dance with joy. They were both happy. But one day the telephone line was damaged, and the motor neuron couldn’t make a telephone call to the motor unit. The motor neuron tried and tried for many years, but the motor neuron couldn’t get through. Then … after a very long time … the telephone line was repaired. The motor neuron could finally call the motor unit. But … sadly … the motor unit had died from a broken heart. And, even modern science can’t bring back the dead!
@@411E109 motor units can be preserved with stimulation to prevent them from dying while waiting.
@@coachgius I’m not an expert on electrical stimulation, but what you wrote seems reasonable. However, we are discussing the motor neurons that were damaged from polio. For the most part we are talking about decades ago. Many decades ago! Electrical stimulation of muscle fibers was known in those days (watching a dead frog’s leg move in high school biology class) but I’m guessing there was no realistic means to provide safe electrical stimulation to thousands of muscle fibers for 50, 60, 70 years.
@@411E109 fair enough, so it is more about dead muscle fibers
@@coachgius Yes. The polio virus attacks motor neurons. It does not effect sensory neurons. The majority of people who had the polio virus in their system had no visible symptoms. But, studies done in the 1940s, by David Bodian, MD, PhD, a distinguished anatomist, indicate at least fifty percent of motor neurons have to be impaired by the polio virus before there is any visibly apparent paralysis. If these motor neurons are not "firing", the muscles will atrophy to such an extent that they are, for all intents and purposes, dead.
Thanks, Dave!
Extreme admiration and love from thE Philippines!!🇵🇭🇵🇭😘

That was helpful. Thanks :)
Is that the big mark on upper arms
What about the DDP that was being sprayed?
Thanks for the info it was very informative ! Although you might want to update your information on outbreaks in the U.S considering the recent events in Rockland and Orange Counties, New York.
That is vaccine derived, which is where all current polio cases and outbreaks have come from since 1993 *according to the World Health Organization*
Thanks thanks you are so good
Dr. My baby is 3 years 3month now I m confuse with this polio vaccines I forget my baby get 2 or 3 opv in this case is it ok to give 1more opv do it harm baby if 1baby get 4 opv also ???
Now that's some scary shit.... paralysis from neck down...wow...
I know. I was there, But ... as strange as it seems ... I was never scared.
Thank you this is just what I needed +1 sub
*sees intro*
Me : *subscribes *
Wow
I'm researching about the atypical polio outbreaks in Los Angeles in 1934 and I'm curious... is the post-polio-Syndrom the same as ME/CFS?
thank you
Thank you professor a lots of knowledge I got from here
Your usename is odd. lol
I love the intro

Imagine if coronavirus and Polio worked together
Yes, prions, you're welcome
Stop giving people ideas to make biological weapons 😒
@@nuageartstudio4193 its not a chemical weapon if it have already existed and caused worldwide panic ;)
U are correct 😅
you mean polio & T-cells?
Amaizing sir
One thing that was mentioned but glossed over is that Polio can only be transmitted by humans. Why is this? What makes transmission in humans so different than say other apes, mammals, etc.? Is this a unique feature of viruses or are most viruses only transmitted by a specific species?
Also:
1) How long does Polio live outside the body?
2) What mechanism of action causes the virus to move from the gastrointestinal area to the CNS? Is this common? Does this happen more with younger or older people? Various races?
3) If electron microscopes weren't invented until the 1950s, how did people in 1910s even know about viruses?
4) If Polio can only survive in humans and has some finite lifespan outside of humans and vaccines were invented almost 70 years ago, why isn't Polio eradicated?
Great video!
1, depends on conditions 2, 1% of people got CNS nerfed 3, smart 4, OPV and anti vaxxers
Did someone seriously dislike this? Why, I bet it’s a troll or one of those flat earthers.
definatelty a flat earther
There’s only 3 dislikes, normally videos will receive a few dislikes from dislike farmers, in order to favor the dislike farmers videos in the TH-cam algorithm.
This gives me hope for getting rid of this COVID-19 crisis 🙂
It's not nearly as deadly so it'll just end up being reduced to a common cold. Which is overcoming it.
Can u please explain about elements and alkaline elements why do they react
Thank you ♥️ from Michgan
How did the iron lung “breathe” for the patient?? All the orifices are outside of the machine?
It is a negative pressure ventilator
It draws air in passively by lowering the pressure inside the tube
Is there no Chance of recovery?
I had it in 1951 before the vaccine came out now I'm in a wheelchair I used to be able to walk with crutches but no longer can do. I just hate it but it is what it is!
I’m sorry to hear that. I’m 20 and lucky, I was vaccinated against this horrible disease.
I had it 1954 at 3 but thanks to cannabis I can still walk…
Thank you very much Sir.
Nice👍
Love the intro
I love your videos mahn keep it up. 👍👌
Keep spreading misinformation - vxs are dangerous and immunosuppresive.
The human figure with his hand up looks like he would be at home on a Pioneer Plaque.
That's how Zeke Yaeger got his spinal fluid
this happened to me as a child when i was 5-6 years old, i was the unlucky one that fell into the 1% total paralysis from neck down.
thankfully i recovered but took few years to be able to walk again and had lasting effects. now at the age of 40, i feel constantly weak - short of breath and constant ache and pains, for past 4 months ive had constant pins and needles. I ignored it thinking it age related .... could this be Post polio syndrome?
Possibly, you could perhaps look up more symptoms online, and if it is worrying enough you could check in with a doctor, though I'm not 100% they would give an answer, they probably could help with a treatment of sort.
We can't confirm by your Symtoms that it is post polio syn, they are several heart and respiratory conditions with similar symtoms by reading online articles with ur symtoms u can't get confirmation with any disease only u will end up with worrying and stress so better meet an doctor and run some tests
Yes, Dipak. It could. If you check, www.polioassociation.org you can find additional information.
Use cannabis and thc products as I had polio at 3 in 1954 and can still walk…low pain..
Thank you Professor. Greetings from Colombia.
Anyone know when baby formula was created? Or what was going on before this outbreak?
Before the video 🤔
During the Video 🤓
After the video 👁👄👁
Now in 19th nov 2022, we have 1 case in region of pidie Aceh, Indonesia
what is polio origin?
Everyone from the UK scrambling to watch this video
I have a question… because as much as I know viruses are nonliving cells, so how are they classified with the genus & a family?
They are not cells, but we use Linnean classification anyway because it is just easier.

This is horrible and even more to know its still happening and than it could be prevented
That’s really interesting as my aunt who lives in Pakistan got polio at a very young age and still has it
Well, she probably fought off the infection itself by now (I know it's probably redundant to say but too many people think people with polio paralysis are still sick and infectious). The body pretty much always wins that fight. Just not always before a paralysis on some body part. It's one of the more cruel diseases out there and thanks to the anti-vaxx community it's still not eradicated. The program came so very close to doing so and it genuinly makes me angry at anti-vaxx people.
Yaa still people at those countries believe vaccine r useless and fear of 1% side effects
@@roepi A big part of it is also military actions in Afghanistan ( and Pakistan ? HC workers can't get in combat zones to give shots
0:06,1:42,2:30,3:00,4:18,5:37
And it's back! Maybe vaccinating people with a mild active strain was not such a great idea after we had almost defeated the virus...
Had almost defeated it? Polio was an enormous problem prior to the vaccine.
The only reason it is back is because the world now is more like a global village, people hop from one continent to the next often bringing these viruses with them from the developing world where it was never eradicated
He knows a lot about the science stuff professor Dave explains

I came here today, as I heard that Paul Alexander died at age of 78. Pakistan and Afghanistan still might have Polio Virus.
Polio outbreaks in Africa are ignored... 2016-19
Can you explain what happened now
Kinda brief explanation: The oral vaccination uses a form of semi live polio to vaccinate, and then is pooped out. But if you live or travel to places with poor sewage/water supply, you can get it if you're unvaccinated. The oral vaccine was meant to be phased out worldwide in favour of the much safer injection, which doesn't contain a 'live' virus in order to work. But that didn't happen, for Reasons.
@@sadmermaid yeah I meant how the person who got infected now got it . They are saying for someone who got a vaccine from a different country . Idk I just wanna know the difference
That is vaccine derived, which is where all current polio cases and outbreaks have come from since 1993 *according to the World Health Organization*
Hello sir I am already polio operation in my childhood but my legs are very thin All friends are hate me Can I bigger legs please any one tell me my solution 😭😭😭😭😭😭😭😭
