Stiles found that hookworm disease occurred most commonly in rural areas. It thrived where the soil was sandy, but not in areas with clay soil. He described hookworm disease (known by the scientific name uncinariasis) as “one of the most important and most common diseases of this part of the South, especially on farms and plantations in sandy districts”. He concluded that a lack of basic sanitation, along with poor nutrition, contributed to southerners’ susceptibility to hookworm infection. Privy is ideal for rural homes: it embodies the principles of the septic tank.
