Abstract In response to the COVID-19 pandemic, we established and sustained local production of Alcohol-Based Hand Rub (ABHR) at a district scale for healthcare facilities and community, public locations in four districts in Uganda. District officials provided space and staff for production units. The project renovated space for production, trained staff on ABHR production, and transported ABHR to key locations. The production officer conducted internal ABHR quality assessments while trained district health inspectors conducted external quality assessments prior to distribution. Information, education, and communication materials accompanied ABHR distribution. Onsite ABHR consumption was monitored by site staff using stock cards. On average, it took 11 days (range: 8–14) and 5,760 USD (range: 4,400–7,710) to setup a production unit. From March to December 2021, 21,600 L of quality-controlled ABHR were produced for 111 healthcare facilities and community locations at an average cost of 4.30 USD/L (range: 3.50–5.76). All ABHR passed both internal and external quality control (average ethanol concentration of 80%, range: 78–81%). This case study demonstrated that establishing centralized, local production of quality-controlled, affordable ABHR at a district-wide scale is feasible and strengthens the ability of healthcare workers and community locations to access and use ABHR during infectious disease outbreaks in low-resource countries.

Abstract School-based water, sanitation and hygiene (WASH) promotion often lacks strategies to sustain behaviors beyond the promotion period. This paper describes school community engagement, in the form of a hygiene committee to institutionalize a school-based hygiene intervention and its role in implementation and sustainability. With formative data on existing hygiene practices from four urban and rural elementary schools, we arranged a workshop to design a low cost, acceptable, and feasible hygiene intervention. We formed hygiene committees including student representatives in each of four additional schools, and piloted and assessed the hygiene intervention. The hygiene committee members' active role supported intervention facilities, materials and maintenance, and promoted targeted behaviors. They encouraged continued use of hygiene materials and provided funds to cover the cost of consumables. The teachers' commitment, student motivation, and financial cost recovery facilitated continued intervention activities. During the 14-months follow-up assessment, the hygiene committee activities were still in place in all schools. The dual involvement of teachers and students in hardware maintenance ensured hygiene intervention consumables availability, functionality, and retention in the pilot schools. The hygiene committee facilitated intervention implementation and sustained functionality. Future school interventions should consider this approach in the implementation processes and cost-recovery strategies.

Abstract This study assessed the effects of COVID-19 on Ghana's WASH system. It focused on low-income households and WASH sector stakeholders using Ayawaso East Municipality as a case study to document lessons from the pandemic's impact on the WASH sector. We used the water and sanitation system approach to understand the effects of COVID-19 mitigation measures on the WASH system. Data were collected through surveys, stakeholder engagements, and document analysis. We found that the government's WASH response increased hygiene practices, solid and liquid waste generation, and water consumption. Sanitation service providers experienced reduced demands for their services, lost clients, and increased operational expenditure. The pandemic's impact is gendered, with women and girls experiencing a greater burden. We argue that responses to the pandemic highlight the need and opportunities for sustainable management of sanitation waste through integrated, circular economy business models, turning waste into valuable resources. Responses to COVID-19 in the WASH system are multisectoral because of its interconnected nature, highlighting the need to integrate sectors beyond water and sanitation. This requires improved institutional structures, policies, investment, and professionalising service providers.

Abstract Water quality monitoring that accounts for seasonal variability is crucial to ensure safe water services at all times, including groundwater self-supply, which provides drinking water for more than 40 million people in urban Indonesia. Seasonal variation of self-supply water quality remains a key evidence gap in Indonesia and elsewhere; therefore, this study investigated the associations between seasonality and faecal contamination of groundwater self-supply in the Indonesian cities of Bekasi and Metro. The study demonstrated mixed results in terms of associations between seasonality and microbial water quality. McNemar's test showed that high concentrations of Escherichia coli (E. coli) (≥100 MPN per 100 mL) were significantly more likely during the wet season than during the dry season in Bekasi (p = 0.050), but not in Metro (p = 0.694). There was no statistically significant association between the season and the presence of E. coli in self-supply sources for both study sites, nor was there a significant association between the season and the presence of high concentrations of E. coli at the point-of-use. At both study sites, presence and high concentrations of E. coli during the dry season significantly increased the risk of contamination in the wet season, but the predictive power was weak. Regular water quality testing complemented by sanitary inspection is required to understand the contamination risks of self-supply sources.

River contamination remains a significant public health problem worldwide, including in Indonesia. In the community, rivers are water resources for many purposes. However, indiscriminate use of antibiotics in the veterinary and medical sectors, the community habit of throwing waste into the river, the inadequate removal of human medicine compounds in WWTP, and poor industrial waste management will induce the spread of pathogenic bacteria and antibiotic resistance between the environment and humans/animals. This review aims to analyse the various factors that influence the emergence of pathogenic Escherichia coli and antimicrobial resistance bacteria (ARB) in the aquatic environment, especially in Indonesia. In conclusion, pathogenic E. coli can adjust its physiological or metabolic conditions to survive in aquatic environments and was found resistant to antibiotics. Meanwhile, this study also describes the potency of the aquatic environment in Indonesia as a vector for the spread of pathogenic E. coli and the growth of ARBs, factors involved in the evolution and spread of antibiotic resistance in aquatic environments, and possible ways to curtail microbial risk to public health and the emergence and spread of antimicrobial resistance in the aquatic environment in Indonesia.

In regions suffering from water scarcity, residents commonly employ several coping strategies such as the use of multiple water sources, water storage and water sharing and borrowing. This study applies a hierarchical linear regression model to investigate the physical (i.e. water source and supply time) and non-physical (i.e. number of families, wealth status, education for household head, house ownership, water treatment and community involvement) factors associated with individual water consumption throughout the Kathmandu Valley, Nepal. During the baseline period (dry season before the 2015 Gorkha earthquake), the average water consumption was 91 litre/capita/day (LPCD) but there was a regional disparity in water consumption, ranging from 16 to 158 LPCD. The statistical analysis indicated that households using many water sources consumed more water regardless of the supply area even in an emergency. In addition, households with many family members used less water per person. During emergencies, households participating in the local community were found to consume more water than households not participating in the community, especially when the water being used was managed by the community.

The importance of water, sanitation, and hygiene (WASH) facilities in school cannot be ignored in protecting children from communicable diseases. However, reports from UNICEF suggest that there is a lack of adequate WASH facilities as well as the dearth of adequate data on available facilities, particularly from developing countries. The present study sought to address this gap and build on the evidence-base of school hygiene and sanitation facilities in rural India. The study also assessed the association between available facilities and the handwashing behavior of students. Data were collected from 28 schools using a modified Joint Monitoring Program (JMP) observation checklist and a self-administered questionnaire. Results indicate a universal coverage of WASH facilities in the sampled schools, though the sufficiency and usability of the infrastructure were inadequate. The study also found better hand hygiene KAP scores among students in schools that had handwashing stations closer to toilets (p = 0.018). We conclude that while India has improved access to facilities under the recent National policy push, there needs to be a continued focus on increasing sufficiency, maintenance and usability of the facilities. Additionally, health promotion activities that include teachers, parents and the community are required to improve the hygiene and sanitation behavior of school children.

Disparities in access to water, sanitation, and hygiene within high-income countries are common and often occur across racial/ethnic lines. The Arab-Bedouins in Israel, a formerly nomadic ethno-national minority, have experienced displacement, forced sedentarization, and poverty since Israel was founded. Land disputes with the government have led to precarious living arrangements, including unrecognized villages that the government considers illegal. We administered a structured questionnaire in one government-planned, two legally recognized, and two unrecognized Bedouin communities in the Negev (190 households). Only 44% (95% CI 37%, 51%) of households had access to both safely managed drinking water and sanitation; nationally Israel reports over 99% coverage for each. In one unrecognized village, only 15% of households had access to safely managed water and sanitation, comparable to low-income countries. The overall 1-week prevalence of diarrhea in children under 5 years of age was 22% (95% CI 17%, 27%), with substantial variation between communities. These results highlight that universal access to safely managed drinking water and sanitation remains a relevant goal, not only for low- and middle-income countries but for high-income countries. Bedouin communities in the Negev are a prime example, emphasizing that historic gains in global development have not uniformly reached marginalized groups within high-income countries.
高收入国家在获得水、环境卫生和个人卫生方面的差异很普遍，而且往往跨越种族/民族界限。以色列的阿拉伯-贝都因人是一个前游牧民族，自以色列建国以来，他们经历了流离失所、被迫定居和贫困。与政府的土地纠纷导致了不稳定的生活安排，包括政府认为非法的未被承认的村庄。我们在内盖夫的一个政府计划的、两个法律认可的和两个未被认可的贝都因社区(190个家庭)进行了结构化问卷调查。只有44%(95%可信区间37%，51%)的家庭能够获得安全管理的饮用水和卫生设施;在以色列全国范围内，这两种疾病的覆盖率都超过99%。在一个未被承认的村庄，只有15%的家庭能够获得安全管理的水和卫生设施，与低收入国家相当。5岁以下儿童1周腹泻总体患病率为22% (95% CI 17%， 27%)，不同社区间差异很大。这些结果突出表明，不仅对低收入和中等收入国家，而且对高收入国家来说，普遍获得安全管理的饮用水和卫生设施仍然是一个相关目标。内盖夫的贝都因社区就是一个典型的例子，它强调全球发展的历史性成果并没有全部惠及高收入国家的边缘群体。

The contamination of drinking water by pathogens poses a serious health hazard in developing countries. Herein, a simple sanitization tool for drinking water is proposed using layered double hydroxide (LDH), which adsorbs most pathogens with its positive charges. By immersing aluminum foil in a mixture of seawater and NaOH without heating, a Mg–Al type LDH was directly formed and adhered to the surface (LDH foil). An LDH foil of 20 cm2 was shaken in 100 mL of test water containing Escherichia coli (DH5α) for up to 24 h and manually removed from the water. The initial viable count of approximately 103 CFU mL−1 decreased to 14 CFU mL−1 in 1 h, reaching 0.25 CFU mL−1 in 24 h; without the LDH foil, the variation 980–1,270 CFU mL−1. The simplicity in its development and use makes LDH foil a promising tool for sanitizing household water among rural residents.

An LDH foil of 20 cm2 was shaken in 100 mL of test water containing Escherichia coli (DH5α) for up to 24 h and manually removed from the water. The initial viable count of approximately 103 CFU mL−1 decreased to 14 CFU mL−1 in 1 h, reaching 0.25 CFU mL−1 in 24 h; without the LDH foil, the variation 980–1,270 CFU mL−1. The simplicity in its development and use makes LDH foil a promising tool for sanitizing household water among rural residents.","PeriodicalId":48893,"journal":{"name":"Journal of Water Sanitation and Hygiene for Development","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47915290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reliable dewatering performance remains a key challenge in fecal sludge management, and the controlling factors or mechanisms are not well understood. There remain limited studies on constituents in feces and fecal sludge and how they affect the dewaterability of fecal sludge. This study aimed at evaluating a range of constituents in feces, and to gain empirical knowledge toward a mechanistic understanding of how they influence dewaterability. In this study, cellulose reduced capillary suction time, decreased supernatant turbidity, and increased cake solids. While hemicellulose decreased supernatant turbidity, lignin increased supernatant turbidity, capillary suction time, and cake solids. Extracellular polymeric substances (EPS) increased both capillary suction time and supernatant turbidity and decreased cake solids, whereas lipids increased turbidity. Cations had no significant effect on dewatering properties. Overall, fecal sludge stored in containments had better dewatering performance than ‘fresh’ fecal sludge, which was attributed to stabilization. Field fecal sludge had a higher relative abundance of Pseudomonas, which is associated with better aggregation, and fewer small particles (<10 μm) that clog filters to reduce dewatering performance. Further understanding of stabilization and developing an agreed-upon metrics of stabilization are essential for predicting fecal sludge dewatering performance, and developing smaller footprint dewatering treatment technologies.
