Quantitative assessment of exposure to fecal contamination in urban environment across nine cities in low-income and lower-middle-income countries and a city in the United States.

BACKGROUND: During 2014 to 2019, the SaniPath Exposure Assessment Tool, a standardized set of methods to evaluate risk of exposure to fecal contamination in the urban environment through multiple exposure pathways, was deployed in 45 neighborhoods in ten cities, including Accra and Kumasi, Ghana; Vellore, India; Maputo, Mozambique; Siem Reap, Cambodia; Atlanta, United States; Dhaka, Bangladesh; Lusaka, Zambia; Kampala, Uganda; Dakar, Senegal. OBJECTIVE: Assess and compare risk of exposure to fecal contamination via multiple pathways in ten cities. METHODS: In total, 4053 environmental samples, 4586 household surveys, 128 community surveys, and 124 school surveys were collected. E. coli concentrations were measured in environmental samples as an indicator of fecal contamination magnitude. Bayesian methods were used to estimate the distributions of fecal contamination concentration and contact frequency. Exposure to fecal contamination was estimated by the Monte Carlo method. The contamination levels of ten environmental compartments, frequency of contact with those compartments for adults and children, and estimated exposure to fecal contamination through any of the surveyed environmental pathways were compared across cities and neighborhoods. RESULTS: Distribution of fecal contamination in the environment and human contact behavior varied by city. Universally, food pathways were the most common dominant route of exposure to fecal contamination across cities in low-income and lower-middle-income countries. Risks of fecal exposure via water pathways, such as open drains, flood water, and municipal drinking water, were site-specific and often limited to smaller geographic areas (i.e., neighborhoods) instead of larger areas (i.e., cities). CONCLUSIONS: Knowledge of the relative contribution to fecal exposure from multiple pathways, and the environmental contamination level and frequency of contact for those "dominant pathways" could provide guidance for Water, Sanitation, and Hygiene (WASH) programming and investments and enable local governments and municipalities to improve intervention strategies to reduce the risk of exposure to fecal contamination.

Towards quality primary health care: the dilemma of Community-Based Health Planning and Services (CHPS) in health service provision in Ghana.

PURPOSE: Over the past two decades, Community-Based Health Planning and Services (CHPS) has been a pragmatic strategy towards universal Primary Health Care (PHC) in Ghana. However, the ability and capacity of these facilities to deliver quality primary health care remain an illusion as they are still crumbling in myriad challenges. These challenges are translated to the poor-quality services provision and low community utilization of CHPS facilities. The study presents a comparative analysis of three communities in the Kassena-Nankana East Municipality, Ghana. DESIGN/METHODOLOGY/APPROACH: Using a mixed-method research design, the study gathered and analysed data from 110 households, three community health officers (CHOs) and three community leaders using semi-structured questionnaires and interview guides. FINDINGS: The findings indicated that the facilities do not have the requisite inputs such as drugs and supplies, logistics, appropriate health personnel, good infrastructure, funding support necessary to deliver quality and appropriate healthcare services that meet the health needs of the communities. For the CHPS to realize their full potentials as PHC facilities, it is required that the needed inputs such as logistics, drugs and appropriate staff are in place to facilitate the activities of CHOs. RESEARCH LIMITATIONS/IMPLICATIONS: Due to the limited number of participants and selection of the study communities, the results may generalization. Also, the researchers acknowledged the inability to interview the district level health officials and the Kassena-Nankana Municipal Assembly during the field visits. This could have provided in-depth knowledge on the findings of this research as well as the validation of the results from the communities' perspective. Several attempts were made to contact and interview district-level authorities which proven futile due to the unavailability of targeted respondents. This resulted in limiting the studies at the community level. However, this limitation does not disprove the findings of this study. PRACTICAL IMPLICATIONS: The article implications for planning primary health care strategies include a keen assessment of community health needs and institutional management of primary health care facilities, equip PHC facilities with adequate resources such as drugs and appropriate staffing to provide the health needs of the communities. ORIGINALITY/VALUE: The paper fulfils the gap in the literature by providing empirical data on how the challenges of primary health care facilities affected the provision of high quality service and how this can affect community's use of the facilities.

Variation in E. coli concentrations in open drains across neighborhoods in Accra, Ghana: The influence of onsite sanitation coverage and interconnectedness of urban environments.

Alongside efforts to improve safe management of feces along the entire sanitation chain, including after the toilet, global sanitation efforts are focusing on universal access 'basic' services: onsite facilities that safely contain excreta away from human contact. Although fecal sludge management is improving in urban areas, open drains remain a common fate for feces in these often densely-populated neighborhoods in low-income countries. To-date, it is unclear to what extent complete coverage of onsite sanitation reduces fecal contamination in the urban environment and how fecal contamination varies within urban drains across neighborhoods by sanitation status within a city. We assessed how neighborhood levels of environmental fecal contamination (via spatially-representative sampling of open drains for E. coli) varied across four neighborhoods with varying income, type and coverage of household sanitation facilities, and population density in Accra, Ghana. Neighborhoods with very high sanitation coverage (≥89%) still had high (>4 log10 CFU/100 mL) E. coli concentrations in drains. Between-neighborhood variation in E. coli levels among the high coverage neighborhoods was significant: drain concentrations in neighborhoods with 93% and 89% coverage (4.7 (95% CI: 4.5, 4.9) & 4.9 (95% CI: 4.5, 5.3) log10 CFU/100 mL, respectively) were higher than in the neighborhood with 97% coverage (4.1 log10 CFU/100 mL, 95% CI: 3.8, 4.4 log10 CFU/100 mL). Compared with the highest coverage neighborhood, the neighborhood with lowest coverage (48%) also had higher E. coli concentrations (5.6 log10 CFU/100 mL, 95% CI: 5.3, 5.9 log10 CFU/100 mL). Although fecal contamination in open drains appeared lower in neighborhoods with higher onsite sanitation coverage (and vice versa), other factors (e.g. fecal sludge management, animals, population density) may affect drain concentrations. These results underscore that neighborhood-level onsite sanitation improvements alone may not sufficiently reduce fecal hazards to public health from open drains. These findings supporting the need for integrated, city-level fecal sludge management alongside multifaceted interventions to reduce fecal contamination levels and human exposure.
