There are many claims made in the first few paragraphs that cite the same source a textbook, but if you read that text book you see that these claims are not actually supported by science based evidence in the text book.
It would be useful to cite more high quality sources as the cause of polio and its means of transmission is not settled. — Preceding unsigned comment added by 24.9.66.63 (talk) 15:55, 22 February 2022 (UTC)
Please be more specific and provide some of these "high quality sources." Maybe we'll learn something. Please sign your comments while you're at it if you want to engage as a member of the community.
As to the second unsigned comment, "Wikipedia" is a community of volunteers from all walks. No one pays me to be here. We all get edited. Easier to avoid taking it personally. --Catrachos (talk) 19:23, 22 July 2022 (UTC)
The article says that the last case of polio in the Americas was in 1991 (Peru). We may want to add that the 1991 case was the last known naturally occurring case of polio in the Americas (if that is true). In addition to a case this month, there was a 2013 case in the US of a 7-month-old who had recently moved from India. Certainly there must be other non-wild cases in the whole of the Americas.
