The result of disinfection of pit latrine with “Gipon” ionized disinfectant solution / Монголын Анагаах Ухаан

Introduction@#Sanitation facility supply and service availability of Mongolia is essential due to the slow process of bacterial decomposition which is getting significant difficulties because of the cold and arid climate. Only 37 percent of Ulaanbaatar’s population is connected to the central sewerage system, and the majority of ger area residents, or 95 percent, use pit latrines in demand of sanitation facility. Numerous studies have shown that the main contaminant of the soil in ger area were pit latrines. It not only pollutes the environment but also affects human health. There is a lack of awareness about the transmission of infectious diseases and options of new sanitation facilities and poor knowledge and bad conditions to introduce new drainage systems. Most pit latrines in ger areas are of poor quality and do not meet relevant standards.@*Goal@#To determine the effect of ”Gipon” ionized disinfectant solution produced by Japanese technology for disinfecting pit latrines@*@#@*Material and Methods@#This study was conducted in December 2019 using a random sampling method. Five households in ger areas were selected and pit latrines were disinfected by ”Gipon” ionized disinfectant solution.@*Results@#The survey covered pit latrines of 5 households in the 21st khoroo of Bayanzurkh district. All owners allowed to participate in the survey. The pit latrines are located approximately 9.8 meters away from the households participated in survey. They have been utilized it for 7.6 years and used by an average of 6 people per day. For inner cover, 60.0 percent are lined with wood, and 40.0 percent are cleaned once a month. Before the use of the disinfectant solution, having taken the swab from door handles, floors and walls of the toilet and were detected Enterobacter spp, E.Coli, and Pseudomonas spp in all samples. </br> However, after one and 24 hours of spreading of the disinfectant solution, the amount of intestinal coliform bacteria and E. coli was reduced dramatically and in some places no bacterial were detected. 72% of the soil near the latrines in the study covered ger areas was contaminated with bacteria. In terms of E.Coli contamination in soil, 60% of them were contaminated in low degree and 32% were medium and 8% were high degree. Anaerobic microorganisms such as Cl.prefrings were accounted for 82% of the total sample, 19% moderate and 81% low contamination.@*Conclusion@#Intestinal coliform bacteria (Enterobacter spp, E.Coli, Pseudomonas spp) and pathogenic bacteria (Serratia spp, Staphylacoccus spp) were not detected and the number of fungi was sharply reduced after 1 and 24 hours using Hypon disinfectant. No intestinal pathogens (Salmonella spp, Citrobacter freundii) were found in the soil near the latrine. The amount of coli titers was reached to the acceptable limits. According to this study, the disinfection activity of “Gipon” solution was ranging from 105 to 104.

Effectiveness of community and school-based sanitation interventions in improving latrine coverage: a systematic review and meta-analysis of randomized controlled interventions

INTRODUCTION@#Approximately 1000 children die each year due to preventable water and sanitation-related diarrheal diseases. Six in 10 people lacked access to safely managed sanitation facilities in 2015. Numerous community- and school-based approaches have been implemented to eradicate open defecation practices, promote latrine ownership, improve situation sanitation, and reduce waterborne disease.@*OBJECTIVE@#Given that current evidence for sanitation interventions seem promising, the aim of this study was to systematically summarize existing research on the effectiveness of community- and school-based randomized controlled sanitation intervention in improving (1) free open defecation (safe feces disposal), (2) latrine usage, (3) latrine coverage or access, and (4) improved latrine coverage or access.@*METHODS@#Eight electronic databases were searched: PubMed, Scopus, WHO Global Health Library (GHL), Virtual Health Library (VHL), POPLINE, Web of Science, Cochrane, and Google Scholar up to 26 April 2019. Original randomized clinical trials addressing community-based or school-based intervention that reported feces disposal and latrine coverage were deemed eligible. More than two researchers independently contributed to screening of papers, data extraction, and bias assessment. We conducted a meta-analysis by random-effects model. The risk of bias was assessed by the Cochrane risk of bias tool.@*RESULTS@#Eighteen papers that matched all criteria and 16 studies were included in the final meta-analysis. Compared to the control, the sanitation intervention significantly increased safe feces disposal (OR 2.19, 95% CI 1.51-3.19, p < 0.05, I@*CONCLUSION@#Our study showed strong evidence for both community- and school-based sanitation interventions as effective for the safe disposal of human excreta. The finding suggests major implications for health policy and design of future intervention in developing countries.

Sanitation practices among internal migrant population: a cross sectional study

Background: Poor sanitation and hygiene are known to be associated with increased morbidity and mortality. Despite all the global efforts 68% population still lacks the basic sanitation facilities. The internal migrant population is a vulnerable group that even lags behind the general population in basic sanitation. This study was aimed to assess sanitation practices among the internal migrant population.Methods: This community based cross sectional study was conducted in a rural village of north-west Delhi from June 2019 to November 2019. People migrated from other parts of the country and residing in the study area for minimum last six months, were included in the study. Data were collected using pre-tested, semi-structured, interviewer-administered study tool, and analysed using SPSS 20.0 software.Results: Two hundred eleven respondents were included in the study. About 88% were using latrine for defecation, out of this 57% were using household sanitary latrines, rest were using community latrines. About 12% were still practicing open defecation. Among those who were using latrine, only about 60% were found regular users. Positive health associated with latrine usage, comfort, privacy, security, presence of latrine in the rented house, quality construction and availability of water were the major motivators and enablers to regular usage of latrine.Conclusions:The internal migrant population is a vulnerable group, with suboptimal sanitation practices. Along with information education communication and behaviour change communication activities, policymakers need to pay special attention to this group in order to achieve global and national sanitation targets.

So the knowledge and practices regarding use of sanitary latrine of primary school children is satisfactory.

A study on open air defecation practices among the population above 6 years in rural field practice area of Santhiram Medical College, Nandyal, Kurnool dist, Andhra Pradesh

Background: Open air defecation can be defined as the excretion of human excreta in open places such as park, roadside, vegetable patch, agricultural fields and railway track other than toilets. Open air defecation may leads to various health problems such as soil pollution, water pollution, contamination of foods and propagation of flies. Nearly 74% of India’s population live in rural areas and the majority of them “go to the fields” for defecation and thereby pollute the environment with human excreta. The aims and objectives of the study were to find the association between defecation practices and socio-demographic variables; to assess the prevalence of hook-worm infestation and anemia among them.Methods: A cross sectional study was conducted. Sample size was 550 and simple random sampling. Chi-square test was applied.Results: The prevalence of open air defecation was 441 (80.2%). 270 (61.2%), 171 (38.8%) were males and females; 23.3% were habit of hand washing with soap after toilet. 87 (19.7%), 63 (14.3%), 43 (9.7%) were found to be having hook worm, round worm, and pin worm infestation in the stool examination. 32 (35.5%), 21 (23.3%), 37 (41.1%) were having severe anemia, moderate anemia, and mild anemia.Conclusions: 335 (60.9%), 106 (19.3%) people were going for open air defecation and inspite of having toilet at home. 226 (51.2%) belong to lower socio economic class. The association between socio demographic profile and open air defecation was significant (?2=0.02, p<0.05).

Socio-cultural determinants of open defecation in rural households of Perambalur district, Tamil Nadu

Background: In many areas of the world, including India, open defecation still remains the predominant norm and poses one of the biggest threats to the health of the people particularly in rural areas.Objectives were to study the prevalence and socio-cultural determinants of open defecation in rural area of Perambalur district.Methods: The present cross-sectional was done in a three randomly selected villages falling under rural field practice area of Department of Community Medicine of Dhanalakshmi Srinivasan Medical College and Hospital in Perambalur district (Tamil Nadu).

Latrine Use And Associated Factors Among Rural Community In Indonesia

@#Indonesia is the second-most-populated country still practicing open defecation. The low utilization of latrines is a big problem that can affect human health and the environment. Several sub-districts in Tanggamus Regency have the lowest reported use of a latrine. This study aimed to determine associated factors of latrine usage in Tanggamus Regency in 2017.. A cross-sectional study was conducted among 399 households in Tanggamus Regency, Lampung. Sampling was proportional to the total number of household in 20 sub-districts. Respondents were interviewed by a structured questionnaire . Data were analyzed using SPSS version 18.0. The study observed that a majority (55.6%) of the respondents used a latrine; furthermore, more than half of all respondents indicated good knowledge (55.9%), positive attitude (57.4%), good economic status (56.1%), access to a proper latrine (57.6%), good support from health office (55.4%), and availability of clean water (53.4%). Multivariate analysis showed that attitude was the most dominant factor related to the utilization of latrine (P<0.05 and adj OR=3.2). Encouraging communities to translate their positive attitudes into the behavior was very important. Policies, community leaders, and heads of households should all be influenced to change community attitudes to drive consistent latrine use.

Discovery of Eurytrema Eggs in Sediment from a Colonial Period Latrine in Taiwan

In this study we take a closer look at the diseases that afflicted Japanese police officers who were stationed in a remote mountainous region of Taiwan from 1921 to 1944. Samples were taken from the latrine at the Huabanuo police outpost, and analyzed for the eggs of intestinal parasites, using microscopy and ELISA. The eggs of Eurytrema sp., (possibly E. pancreaticum), whipworm and roundworm were shown to be present. True infection with Eurytrema would indicate that the policemen ate uncooked grasshoppers and crickets infected with the parasite. However, false parasitism might also occur if the policemen ate the uncooked intestines of infected cattle, and the Eurytrema eggs passed through the human intestines. These findings provide an insight into the diet and health of the Japanese colonists in Taiwan nearly a century ago.

Saneamiento y relación con la salud de la niñez en el contexto mundial 2004 / Sanitation as related to children`s health in the world context 2004

Se determina el efecto mundial de los diferentes tipos de cobertura de disposición de excretas, DE, definidas en el marco del concepto "Instalaciones de Saneamiento Mejoradas", ISM, de OMS y UNICEF, sobre las tasas de mortalidad en niños menores de 5 años, TM menor 5 años. Para lograrlo se recolectaron datos de cobertura de DE en 161 países del "Programa Conjunto de Monitoreo" del 2004. Las TM menor 5 años se obtuvieron del informe "Progreso para la Infancia: un balance sobre agua y saneamiento". Los datos de ISM se clasificaron en totales, ISM-total, alcantarillado, DEA, tanques sépticos y letrinas, DET y L, y sin servicio, DESS. Se aplicaron 3 métodos estadísticos: distribución de frecuencias entre los intervalos de ambas variables, la correlación simple de Pearson entre los tipos de evacuación de excretas y las TM menor 5 años y la correlación Parcial al 95 por ciento de confianza pero controlando variables. Los resultados indican que a mayor cobertura mediante ISM-total menor es la TM menor 5 años, con una correlación de menos 0.782, mientras que las coberturas con DEA tienen mayor impacto sobre la disminución de la mortalidad que cuando se realiza por DET y L. Estos resultados se ratifican con las otras pruebas estadísticas y comprueban la hipótesis.

The worldwide effect on mortality in children under five years of age (MR < 5 years ) is determined for the different types of excreta disposal (ED) coverage, as defined in the framework of "Improved Sanitation Facilities (ISF)", established by the WHO and UNICEF. To accomplish this, ED coverage data was collected from 161 countries participating in the "Joint Monitoring Programme" in 2004. The mortality rates were obtained from "Progress for Children: A Balance on Water and Sanitation". ISF data were classified as: total (total-ISF), sewage (DEA), septic tanks and latrines (DET and L), and without services (DESS). Three statistical methods were applied: frequency distribution between the intervals of both variables, Pearson´s simple correlation between the types of excreta evacuation and the MR<5 years, and partial correlation at 95% confidence but controlling the variables. Results indicate that as total coverage (total-ISF) increases, there is a lower incidence of mortality (MR < 5 years), with a correlation of –0,782; while DEA coverage has a greater impact over mortality decrease as compared to DET and L. The results are ratified with the other statistical tests and prove the hypothesis.

Investigation of Decontamination of Feces in Household Latrine in Some Epidemic Areas of Schistosome in Hubei / 环境与健康杂志

Objective To evaluate the current sanitary situation of the rural household latrine and the effects of decontamination of the feces in some epidemic areas of schistosome in Hubei province.Methods Six villages(4 villages with the sanitary latrines,2 villages with the non-sanitary latrines) were chosen for the investigation and 30 latrines were selected randomly in each village in September of 2007.The structure of the latrine and the situation of the faecal treatment were investigated by questionnaires.At the same time,the feces samples were collected and detected according to the related sanitary standards.Results The rate of the sanitary latrines without maggots,pupas and flies was 95%,while the rate of the non-sanitary latrines with the same situation was 33.33%.After non-hazardous treatment in the three-case-cesspool and the firedamp latrines,the qualified rates of the roundworm eggs were 95.6% and 98.6% respectively;the qualified rates of fecal coliform were both 100%;no schistosome eggs,the alive schistosome eggs and the alive roundworm eggs were detected.The morbidity rate of schistosomiasis of the villages with the sanitary latrines was 43.7%,lower than those with the non-sanitary latrines.Conclusion The faecal treatment of the rural household latrine in epidemic areas of schistosome can improve the sanitation and kill the pathogens in faeces effectively,and also can decrease the morbidity rate of schistosomiasis obviously.
