I saw this video about Mark O'Brien some time ago and I was impressed.
I was looking for it today again, but it is not there anymore. I am very sorry.
I am RN and I was working (1953) it the hospital with polio patient. It was in Czechoslovakia, I was only 18 years old.
Now I live in the US for many years. Because of recent situation with coronavirus I started to write a story about polio, as a reminder of another dangerous VIRUS. It was why I was looking for history of polio.
