Water, sanitation and hygiene (WASH) in schools in Brazil pre-and peri-COVID-19 pandemic: Are schools making any progress?

The Status of Water and Sanitation Facilities in Public Primary Schools in Oyo State, Nigeria: Progress toward Achieving the SDG 6

Water and sanitation facilities in schools are directly linked to the attainment of Sustainable Development Goal (SDG) 6; however, these facilities are often grossly inadequate in both quality and quantity in public primary schools (PPS) in developing countries. This study examined the existing water and sanitation facilities in PPS in Oyo State, Nigeria, to identify disparities. Using ANOVA, variables extracted from the 2020 Oyo State Annual School Census report were analyzed and mapped to reveal spatial distribution at the local government level. Five water sources and 4 types of sanitation facilities were identified. Significant variations were observed across local government types (urban, semi-urban & rural, and rural) with respect to enrollment (P = .000), total number of toilets (P = .033), PPS with wells (P = .002), PPS with no water source (P = .001), PPS with flush toilets (P = .001), and PPS with other toilet types (P = .011). With sanitation facility availability below 20%, open defecation is likely to be prevalent in these schools. For the well-being of the pupils and the entire population of the state, the government needs to prioritize the provision of potable drinking water and improved sanitation facilities in PPS, while considering the need for facilities to be gender sensitive.

WASH-friendly schools for whom? Integrating the perception of different school stakeholders in Brazil

Ensuring that schools are water, sanitation and hygiene (WASH) friendly requires WASH to be visibly implemented, inclusive and sustainable, engaging the entire school community, including direct and indirect stakeholders (school staff, students and their families). However, students, staff, and parents are often overlooked in the design of WASH solutions. This study aims to contrast different school stakeholders' perspectives on WASH and evaluate the extent to which the Human Right to Water and Sanitation (HRtWS) and its normative contents are being realized in schools within the basic education system, covering students aged 0 to 18. For that purpose, a mixed-method study was conducted involving seven schools located in a small municipality in the southeast region of Brazil. Data collection methods included on-site observations in schools, in-depth interviews with school staff and parents/legal guardians of students, and a one-day art-based research workshop with students around drinking water, sanitation, solid waste management and COVID-19. Several inconsistencies were identified when comparing primary findings with the schools' information previously provided by the Brazilian Government, including differences in the number of schools and levels of education offered, water sources, absence of bathrooms, and waste burning instead of solid waste collection. A clear violation of all the normative contents of the HRtWS was observed, which, in turn, were triggering and exposing students to incidents of violence such as bullying and verbal abuse. There was a misalignment among stakeholders about which interventions implemented amidst the COVID-19 pandemic are still in place. Moreover, discrepancies among school stakeholders' perceptions of WASH suggest insufficient communication among actors. As a result of this research, a list of recommendations formulated by stakeholders and the involvement and alignment of all stakeholders are the first steps in successfully co-creating solutions.

Evaluation of the drinking water parameters in primary and secondary schools located in the Gaziantep Province Center

This cross-sectional study aimed to assess the drinking water parameters in primary and secondary schools. A questionnaire encompassing the schools' general characteristics and information about drinking water was administered to school administrators. Drinking water samples were taken from 60 schools to evaluate drinking water parameters. The data were analyzed using Chi-Square, Mann-Whitney U, and Kruskall-Wallis tests, T-test, and SPSS 22.0 software. Non-compliance with national legislation was observed in 16.7% of schools during drinking water analysis. The microbiological parameters exceeded the threshold values in 90% of the schools where the analysis results of the drinking water were deemed inadequate. The analysis yielded no discernible variations based on school district or type. Mains water was the primary drinking water source in 91.7% of schools. The rate was lower in rural schools compared to urban schools, with a difference of 85 and 95%, respectively. It was found that 41.7% of schools lacked canteens or the sale of packaged water. Consequently, the availability of tap water in schools falls short of the desired standard. It is imperative to investigate the factors leading to microbiological contamination in school drinking water and formulate short-, medium-, and long-term strategies to enhance its safety.

Preparing schools for future pandemics: Insights on water, sanitation and hygiene solutions from the Brazilian school reopening policies

Post-COVID-19, schools urgently need to enhance infection control and prevention (IPC) measures, including water, sanitation, and hygiene (WASH), to prepare for future outbreaks and pandemics. Particularly in Brazil, that is of particular concern, as students are still recovering from the 20th longest school closure in the world. Hence, the current study had two goals: (i) to describe WASH solutions outlined in policies released at the federal, state, and capital city levels in Brazil during the COVID-19 pandemic for the safe reopening of schools and (ii) to discuss their potential to enhance school's capacity to remain operational during a new pandemic or outbreak. With a qualitative exploratory approach, we performed content analysis to discuss the direction (what, where, how and for whom?) of 66 public policies by integrating four frameworks. Solutions were discussed in the light of the principles of human rights and the human rights to water and sanitation, international guidelines for WASH and IPC in schools and the Sphere minimum standards for humanitarian aid. One hundred and fifty-nine solutions, spanning five thematic areas and five population groups, including software and hardware interventions, were compiled for potential use in Brazil and beyond. While suggested solutions have the potential to provide a cleaner and safer learning environment, it is essential to exercise caution when implementing these measures and adapt them to the specific circumstances of each school.

Water, sanitation, and hygiene global research: evolution, trends, and knowledge structure

Water, sanitation, and hygiene (WASH) services play a crucial role in promoting public and environmental health as well as social and economic development. At the global level, particularly in the developing world, WASH issues continue to present significant challenges. These challenges have been further intensified by factors such as the COVID-19 pandemic, escalating conflicts, climate change, water scarcity, and rising inequality. The scientific community has actively engaged in constructive discussions on these issues, as evidenced by the notable research findings. Therefore, the aim of this study was to comprehensively examine and evaluate global knowledge on WASH. To search for relevant publications, the Scopus database was utilized using specific terms associated with WASH. VOSviewer 1.6.18 software was employed to generate network visualization maps, which assessed collaborative patterns and research trends in the field of WASH. The research output of countries was adjusted considering their gross domestic product (GDP) and population size. The total number of WASH-related publications, including all types of documents, was 1805. By narrowing the search to articles and reviews, the overall global productivity yielded 1589 documents: 1367 (86.0%) original articles and 222 (14.0%) review articles. The USA had the highest number of WASH publications (n = 668; 42.0%), followed by the UK (n = 396; 24.9%), Switzerland (n = 151; 9.5%), and Australia (n = 141; 8.9%). Ethiopia emerged as the leading country in terms of GDP per capita and the number of publications, followed by Uganda, Malawi, India, and Bangladesh. The USA, the UK, and Switzerland exhibited the most extensive collaboration among countries. The main research areas encompassed the role of WASH in sustainable development, the impacts of inadequate access to WASH services on gender equality, children, infants, and the outbreak of COVID-19 and other diseases, as well as the significance of hygiene practices and community and school-based WASH interventions in reducing infections. This study provides a novel analysis of global WASH-related research and highlights the distribution of outcomes across nations. Continued and increased collaboration between developed and developing nations will facilitate the sharing of responsibility for WASH research outcomes and the implementation of effective policies.

Toxicity of chemical-based hand sanitizers on children and the development of natural alternatives: a computational approach

The unintended exposure of children to hand sanitizers poses a high risk of potentially fatal complications. Skin irritation, dryness, cracking, peeling, hypoglycemia, apnea, and acidosis are examples of unintended consequences of hand sanitizer. The sanitizer reportedly kills normal microbial flora on hands, which usually promotes innate immunity among children under 12. Children are more susceptible to the toxicity associated with the chemical constituents of marketed chemical-based hand sanitizers; however, the studies to develop sanitizer formulations for children are rudimentary. The adverse events limit the use of hand sanitizers specifically in children because of their sensitive and delicate skin. Additionally, it is reported that many chemical-based hand sanitizer formulations, especially alcohol-based ones may also contain contaminants like methanol, acetaldehyde, benzene, isopropanol, and ethyl-acetate. These contaminants are found to be hazardous to human health exhibiting toxicity on ingestion, inhalation, or dermal exposure, especially in children. Therefore, it is important to design novel, innovative, safer sanitizer formulations for children. The study aims to discuss the toxic contaminants in chemical-based sanitizer formulations and propose a design for novel herbal formulations with minimal toxicity and adverse effects, especially for children. The review focuses on ADMET analysis of the common contaminants in hand sanitizers, molecular docking, Lipinski's rule of five analysis, and molecular simulation studies to analyze the efficacy of interaction with the receptor leading to anti-microbial activity and drug-likeness of the compound. The in silico methods can effectively validate the potential efficacy of novel formulations of hand sanitizers designed for children as an efficient alternative to chemical-based sanitizers with greater efficacy and the absence of toxic contaminants.
