Human populations throughout the world can be found in diverse conditions. A proportion of the population of developing countries lives in deprived conditions characterized by ramshackle housing, lack of piped water and sanitation, and widespread fecal contamination of the environment. Enteric infections, particularly due to bacterial pathogenes, are readily transmitted under these circumstances. In contrast, the majority of inhabitants of industrialized countries live in a sanitary environment that generally discourages the transmission of enteric pathogenes, particularly bacteria. In both these ecologic niches, changes in human ecology and behavior are leading to the emergence of certain enteric infections. Relevant factors in developing areas include urbanization (leading to periurban slums), diminished breastfeeding, and political upheaval that results in population migrations. In industrialized areas, large-scale food production (e.g., enormous poultry farms), distribution, and retailing (e.g., fast-food chains) create opportunities where widespread and extensive outbreaks of food-borne enteric infection can ensue if a breakdown in food hygiene occurs.

Diarrhea is a leading cause of child mortality worldwide. Early recognition of symptoms and referral to medical treatment are essential. In 2007, we conducted a Healthcare Utilization and Attitudes Survey (HUAS) of 1,000 children randomly selected from a population census to define care-seeking patterns for diarrheal disease in Bamako, Mali, in preparation for the Global Enteric Multicenter Study (GEMS). We found that 57% of caretakers sought care for their child's diarrheal illness from traditional healers, and 27% of caretakers sought care from the government health center (GHC). Weighted logistic regression showed that seeking care from a traditional healer was associated with more severe reported diarrheal disease, like decreased urination (odds ratio [OR] = 3.35, 95% confidence interval [95% CI] = 1.19–9.41) and mucus or pus in stool (OR = 4.42, 95% CI = 1.35–14.51), along with other indicators of perceived susceptibility. A locally designed traditional healer referral system was, therefore, created that emphasized more severe disease. This system may serve as a model for health systems in West Africa.
