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.

[@barbh1]

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.

[@roepi]

@@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.

[@roepi]

@@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.

[@Giuseppe_coachgius]

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.

[@411E109]

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!

[@Giuseppe_coachgius]

@@411E109 motor units can be preserved with stimulation to prevent them from dying while waiting.

[@411E109]

@@Giuseppe_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.

[@Giuseppe_coachgius]

@@411E109 fair enough, so it is more about dead muscle fibers

[@411E109]

@@Giuseppe_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.

Nice description

[@j_m_b_1914]

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!
