This historic diagram, which had been digitally enhanced and colorized, depicted an example of the unsanitary placement of a farm house privy from which animals were able to convey infection to human beings. Note that the back of structure was in need of repair, thereby, allowing farm animals to access contaminated areas inoculating themselves with infectious agents found in the waste. Note also the proximity of the animals to the farm family's living spaces, and the child whose barefoot state increased her susceptibility to diseases such as hookworm, as well as what might be contracted from the animals.
