===Amoebic dysentery outbreak===
From June to November 1933, there was an outbreak of [[amoebic dysentery]] associated with the fair. There were more than a thousand cases, resulting in 98 deaths.<ref>{{cite journal |author=Markell, E.K. |title=The 1933 Chicago outbreak of amebiasis |journal=Western Journal of Medicine |volume=144 |issue=6 |pages=750 |date=June 1986| pmid=3524005 |pmc=1306777 }}</ref><ref>{{cite web|title=Water and Waste Systems|url=http://www4.ncsu.edu/~rifki/arc414/Water%20and%20Waste/WaterWaste_09.htm|archive-url=https://web.archive.org/web/20170119121357/http://www4.ncsu.edu/~rifki/arc414/Water%20and%20Waste/WaterWaste_09.htm|archive-date=January 19, 2017|url-status=dead|access-date=January 19, 2017}}</ref><ref>{{Cite web |date=August 16, 2022 |title=2022 National Backflow Prevention Day! |url=https://arbiterbackflow.com/blog/f/2022-national-backflow-prevention-day |access-date=October 1, 2023 |website=Arbiter Backflow}}</ref> Joel Connolly of the Chicago Bureau of Sanitary Engineering brought the outbreak to an end when he found that defective plumbing permitted sewage to contaminate drinking water in two hotels.

===Extension===
Originally, the fair was scheduled only to run until November 12, 1933, but it was so successful that it was opened again to run from May 26 to October 31, 1934.<ref name="encyclopedia">{{cite encyclopedia|title=Century of Progress Exposition|first=Robert W.|last=Rydell|url=http://encyclopedia.chicagohistory.org/pages/225.html|encyclopedia=Encyclopedia of Chicago|year=2005|access-date=May 10, 2011|archive-date=May 14, 2011|archive-url=https://web.archive.org/web/20110514034330/http://www.encyclopedia.chicagohistory.org/pages/225.html|url-status=live}}</ref> The fair was financed through the sale of memberships, which allowed purchases of a certain number of admissions once the park was open. More than $800,000 (equal to ${{Inflation|US|800000|1934|fmt=c}} today) was raised in this manner as the country was in the [[Great Depression]]. A $10&nbsp;million [[Municipal bond|bond]] was issued on October 28, 1929, the day before the [[Wall Street Crash of 1929|stock market crashed]]. By the time the fair closed in 1933, half of these notes had been retired, with the entire debt paid by the time the fair closed in 1934. For the first time in American history, an international fair had paid for itself. In its two years, it had attracted 48,769,227 visitors. According to [[James Truslow Adams]]'s ''Dictionary of American History'', during the 170 days beginning May 27, 1933, there were 22,565,859 paid admissions; during the 163 days beginning May 26, 1934, there were 16,486,377; a total of 39,052,236.<ref>{{Cite web |title=1933 Chicago |url=https://www.bie-paris.org/site/en/1933-chicago |access-date=February 12, 2024 |website=www.bie-paris.org}}</ref><!--need page, date, etc.-->
