Bet you took elementary level science, didn'tcha. Maybe you should look at more advanced science courses, you could retake elementary level then move on to high school level.Clean water and Modern sewage system.When Polio outbreaks were happening in the late 50’s and early 60’s, many of the adverse effects were due to the lack of clean conditions. The truth is over 90% of the cases where people contracted Polio, the symptoms experienced were very minute. Most symptoms included a slight fever, headache, sore throat, and vomiting. The recovery time was 24 – 72 hrs. Once recovered, the person now has a life time immunity to Polio. 5% of people who contracted Polio had less symptoms and recovery time was much less. They would see some sore throat and possibly a fever. Rare cases saw diarrhea. Then we get to 3% of people who had a bit more extreme cases where they may have seen some limb weakness and partial paralysis that would be experienced for 2 – 10 days. This only happened when areas of the brain that controlled limbs were irritated by a form of viral meningitis. All cases saw a complete recovery and life long immunity. Now we get to the worst cases of them all. Less than 2% of cases saw some form of more serious paralysis. Of that 2% though 50% saw complete recovery over time from the paralysis.
The Polio Vaccine Myth: “The Vaccine Stopped Polio”
And today, nobody gets Polio. Gee, wonder why that is............
