Into the Outhouse

Outhouses in the early 19th century were introduced to the Southern states because of the discovery that hookworms were responsible for large portions of the population suffering from anemia. I heard an interesting story on the radio about this topic and I would like to dig deeper than the summary they provided.

My questions are as follows: how did they solve widespread parasitic infections in the South? how did they affect the Southern economy? how did Southern communities respond to them in the early 20th? I think that these questions will help me to discover and share a story about hygiene being linked to economics.
