Throughout human history, pathogens transmitted through feces from person to person have caused substantial mortality. Over a century ago civil engineers in high income countries developed approaches to collect and remove feces from the environment that in communities with high incomes and strong governments markedly reduced the burden of enteric disease. These approaches, however, have not been successfully extended to impoverished communities in low income countries. Water/sanitation/hygiene professionals have attempted, with only limited success, to reduce fecal exposure and human disease in the absence of definitive civil engineering approaches. Medical professionals have worked to develop vaccines against some of the most important fecal oral pathogens. Each of these approaches needs further development and adaptation to optimally address the burden of fecally transmitted diseases in impoverished communities.
