Environmental transmission of diarrheal pathogens in low and middle income countries

Globally more than half a million children die every year from diarrheal diseases. This Perspective suggests that reductions in diarrheal disease transmission in LMICs can be achieved by accounting for site-specific factors when designing environmental interventions. This is discussed in the context of the characteristics of the most important diarrheal diseases as well as environmental reservoirs.
