Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route.SuSanA (2008)Towards more sustainable sanitation solutions Sustainable Sanitation Alliance (SuSanA) For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis (a type of intestinal worm infection or helminthiasis), cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few. A range of sanitation technologies and approaches exists. Some examples are community-led total sanitation, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polio
Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 70% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases.. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection. Polio occurs naturally only in humans. It is highly infectious, and is spread from person to person either through fecal-oral transmission (e.g. poor hygiene, or by ingestion of food or water contaminated by human feces), or via the oral-oral route. Those who are infected may spread the disease for up to six weeks even if no symptoms are present. The disease may be diagnosed ...

Improved Sanitation
Improved sanitation (related to but distinct from a " safely managed sanitation service") is a term used to categorize types of sanitation for monitoring purposes. It refers to the management of human feces at the household level. The term was coined by the Joint Monitoring Program (JMP) for Water Supply and Sanitation of UNICEF and WHO in 2002 to help monitor the progress towards Goal Number 7 of the Millennium Development Goals (MDGs). The opposite of "improved sanitation" has been termed "unimproved sanitation" in the JMP definitions. The same terms are used to monitor progress towards Sustainable Development Goal 6 (Target 6.2, Indicator 6.2.1) from 2015 onwards.WHO and UNICEF (2017Progress on Drinking Water, Sanitation and Hygiene: 2017 Update and SDG Baselines Geneva: World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF), 2017 Here, they are a component of the definition for "safely managed sanitation service".

Open Defecation
Open defecation is the human practice of defecating outdoors ("in the open") rather than into a toilet. People may choose fields, bushes, forests, ditches, streets, canals, or other open spaces for defecation. They do so either because they do not have a toilet readily accessible or due to traditional cultural practices. The practice is common where sanitation infrastructure and services are not available. Even if toilets are available, behavior change efforts may still be needed to promote the use of toilets. 'Open defecation free' (ODF) is a term used to describe communities that have shifted to using toilets instead of open defecation. This can happen, for example, after community-led total sanitation programs have been implemented. Open defecation can pollute the environment and cause health problems and diseases. High levels of open defecation are linked to high child mortality, poor nutrition, poverty, and large disparities between rich and poor. Ending open defecation ...

Joint Monitoring Programme For Water Supply And Sanitation
The Joint Monitoring Programme (JMP) for Water Supply and Sanitation by WHO and UNICEF is the official United Nations mechanism tasked with monitoring progress towards the Sustainable Development Goal Number 6 (SDG 6) since 2016. Previously, until 2015, JMP was tasked with monitoring the Millennium Development Goal (MDG) relating to drinking water and sanitation (MDG 7, Target 7c), which was to: "Halve, by 2015, the proportion of people without sustainable access to safe drinking-water and basic sanitation". The JMP is housed within the World Health Organization and UNICEF, and supported by a Strategic Advisory Group of independent technical and policy experts as well as various Technical Task Forces convened around important specific topics. Activities The JMP's four priority areas of activity for 2010-2015 were: * maintaining the integrity of the JMP database and ensuring accurate global estimates; * disseminating data to stakeholders; * fulfilling the JMP's normative role ...

Sanitation Worker
A sanitation worker (or sanitary worker) is a person responsible for cleaning, maintaining, operating, or emptying the equipment or technology at any step of the sanitation chain.World Bank, ILO, WaterAid, and WHO (2019)Health, Safety and Dignity of Sanitation Workers: An Initial Assessment World Bank, Washington, DC. This is the definition used in the narrower sense within the WASH sector. More broadly speaking, sanitation workers may also be involved in cleaning streets, parks, public spaces, sewers, stormwater drains, and public toilets. Another definition is: "The moment an individual’s waste is outsourced to another, it becomes sanitation work." Some organizations use the term specifically for municipal solid waste collectors, whereas others exclude the workers involved in management of solid waste (rubbish, trash) sector from its definition. Sanitation workers are essential in maintaining safe sanitation services in homes, schools, hospitals, and other settings and prote ...

Reuse Of Excreta
Reuse of human excreta is the safe, beneficial use of treated human excreta after applying suitable treatment steps and risk management approaches that are customized for the intended reuse application. Beneficial uses of the treated excreta may focus on using the plant-available nutrients (mainly nitrogen, phosphorus and potassium) that are contained in the treated excreta. They may also make use of the organic matter and energy contained in the excreta. To a lesser extent, reuse of the excreta's water content might also take place, although this is better known as water reclamation from municipal wastewater. The intended reuse applications for the nutrient content may include: soil conditioner or fertilizer in agriculture or horticultural activities. Other reuse applications, which focus more on the organic matter content of the excreta, include use as a fuel source or as an energy source in the form of biogas. There is a large and growing number of treatment options to mak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Sanitation
Sustainable sanitation is a sanitation system designed to meet certain criteria and to work well over the long-term. Sustainable sanitation systems consider the entire "sanitation value chain", from the experience of the user, Human excreta, excreta and wastewater collection methods, transportation or conveyance of waste, treatment, and reuse or disposal.Tilley, E., Ulrich, L., Lüthi, C., Reymond, Ph. and Zurbrügg, C. (2014)Compendium of Sanitation Systems and Technologies. 2nd Revised Edition Swiss Federal Institute of Aquatic Science and Technology (Eawag), Duebendorf, Switzerland The Sustainable Sanitation Alliance (SuSanA) includes five features (or criteria) in its definition of "sustainable sanitation": Systems need to be economically and socially acceptable, technically and institutionally appropriate and protect the environment and natural resources. The purpose of sustainable sanitation is the same as sanitation in general: to protect Public health, human health. How ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emergency Sanitation
Emergency sanitation is the management and technical processes required to provide sanitation in emergency situations. Emergency sanitation is required during humanitarian relief operations for refugees, people affected by natural disasters and internally displaced persons. There are three phases of emergency response: Immediate, short term and long term. In the immediate phase, the focus is on managing open defecation, and toilet technologies might include very basic latrines, pit latrines, bucket toilets, container-based toilets, chemical toilets. The short term phase might also involve technologies such as urine-diverting dry toilets, septic tanks, decentralized wastewater systems. Providing handwashing facilities and management of fecal sludge are also part of emergency sanitation. The immediate sanitation phase focuses on the provision of proper waste management resources. The main course of action during this stage is reducing open defecation. It is implemented as a course ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological Sanitation
Ecological sanitation, commonly abbreviated as ecosan (also spelled eco-san or EcoSan), is an approach to sanitation provision which aims to safely reuse excreta in agriculture. It is an approach, rather than a technology or a device which is characterized by a desire to "close the loop", mainly for the nutrients and organic matter between sanitation and agriculture in a safe manner. One of the aims is to minimise the use of non-renewable resources. When properly designed and operated, ecosan systems provide a hygienically safe system to convert human excreta into nutrients to be returned to the soil, and water to be returned to the land. Ecosan is also called resource-oriented sanitation. Definition The definition of ecosan has varied in the past. In 2012, a widely accepted definition of ecosan was formulated by Swedish experts: "Ecological sanitation systems are systems which allow for the safe recycling of nutrients to crop production in such a way that the use of non-ren ...

Container-based Sanitation
Container-based sanitation (abbreviated as CBS) refers to a sanitation system where toilets collect human excreta in sealable, removable containers (also called cartridges) that are transported to treatment facilities. This type of sanitation involves a commercial service which provides certain types of portable toilets, and delivers empty containers when picking up full ones. The service transports and safely disposes of or reuses collected excreta. The cost of collection of excreta is usually borne by the users. With suitable development, support and functioning partnerships, CBS can be used to provide low-income urban populations with safe collection, transport and treatment of excrement at a lower cost than installing and maintaining sewers. In most cases, CBS is based on the use of urine-diverting dry toilets. A key benefit of container-based sanitation systems is its relative low-cost. In addition, the process assures there is no human contact with excreta. Feces can be co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
