Pervasive Exposure to Fecal Contamination in Low-Income Neighborhoods in Accra, Ghana Open Access
Hurd, Jacqueline (2014)
Abstract
BACKGROUND: Globally, diarrhea contributes to about 800,000 fatalities in children under five each year, and is a primary cause of mortality in developing countries. Rapid urbanization in low-income countries has led to a growing sanitation crisis. A need exists for more effective WASH interventions in low-resource urban environments that can minimize the transmission of feces and reduce the rate of diarrheal illnesses. Effective interventions require evidence-based research that highlights risk behaviors and perceptions of fecal contamination risk in people's daily lives.
METHODS: This study examines the context of fecal contamination during daily activities among residents in low resource urban settings of Accra, Ghana. Qualitative data were collected through 16 focus group discussions to understand the daily behaviors that place people at risk of fecal contamination. Data were collected and analyzed using a grounded theory approach to develop a conceptual framework of the context of fecal contamination in low-income neighborhoods of Accra. MaxQDA10 software was used for data analysis.
RESULTS: Results show that latrine use is low in these neighborhoods leading to a range of alternative methods of fecal disposal (e.g. take aways, chamber pots, hawker's containers, and open defecation) that contribute to fecal contamination throughout neighborhoods. Feces were further spread through refuse dumping, poor refuse collection systems, recreational activities, and occupational tasks of residents. Fecal contamination also occurred between public and private domains contributing to pervasive fecal contamination throughout the study neighborhoods.
DISCUSSION: This study is unique in describing in detail the range of fecal disposal methods used by residents in their daily lives, and how feces are transmitted between public and private domains throughout low-resource urban neighborhoods. The context of fecal disposal and contamination throughout neighborhoods suggests that people may be frequently exposed to feces through regular daily activities, which may lead to a high frequency of fecal transmission overtime.
CONCLUSION: These pathways of fecal contamination underscore the pervasiveness of risk for fecal contamination throughout low-income urban neighborhoods, suggesting the need for multi-pronged interventions that target multiple pathways of feces transmission.
