00:00 Hookworms, a type of roundworm, have had a significant impact on the social and historical context of the Southern United States, and they primarily infect humans through the feet and feed on blood.

05:21 Hookworms are parasites that have co-evolved with humans and infect them through the feet, making their way to the blood vessels, lungs, and finally the small intestine, where they latch on and start sucking blood, reproducing and laying up to 30,000 eggs a day, which are then excreted in fecal matter and can reinfect others if stepped on without shoes.

10:46 Hookworm larvae can hatch from eggs in fecal matter and crawl back into your foot, increasing the worm burden and the risk of infection, especially if human manure is used as fertilizer in fields where people work barefoot.

15:58 Hookworm infection in the American South led to the stereotype of Southerners being lazy and dumb, as the majority of the poverty-stricken rural Southern poor were infected with hookworm due to poor sanitation and lack of access to shoes and bedpans.

21:25 Hookworm infections in the American South caused physical and developmental stunting, lower IQs, learning disabilities, and iron deficiency, which compounded poverty and kept the region economically disadvantaged, and the problem was not understood until Charles Stiles discovered the link in 1902.

26:16 Despite facing resistance from local doctors and skepticism from Southerners, Charles Stiles was able to secure funding from John D. Rockefeller to establish the Rockefeller Sanitary Commission for the eradication of hookworm disease in the American South.

31:28 The Rockefeller Sanitary Commission for the eradication of hookworm disease in the American South used a multi-faceted approach, including an awareness campaign in schools, community involvement, and temporary clinics that were treated like events, to combat the disease.

36:35 The Rockefeller Sanitary Commission's efforts to eradicate hookworm in the American South were successful in raising awareness and establishing public health networks, but reinfection remained a major problem until the 1940s when indoor plumbing became more prevalent.

41:14 The modernization of the American South, including improvements in food, plumbing, and living conditions, led to the decline of hookworm infections, but the disease still remains a major problem in impoverished areas around the world.

46:27 Research suggests that hookworm infections may have potential benefits in treating certain diseases, such as asthma, and that the eradication of parasitic worms from our bodies may have led to the rise of autoimmune diseases like multiple sclerosis and Crohn's disease.
