81-780: Missionaries visited Nias Island in the early 20th century, and Christianity was reported to have spread to Lahewa by 1915. Lahewa and Nias Island were struck hard by the Indian Ocean tsunami of 26 December 2004. 150 were reported dead and 3000 homeless in Lahewa, Sirombu and Mandrehe , the tsunami destroying most of the fishing boats. Due to the poverty-stricken conditions, the people of Lahewa have traditionally suffered from diarrhoea , malaria and dengue fever . The International Federation of Red Cross and Red Crescent Societies (IFRC), with support from Canadian Red Cross have worked together to improve water and sanitation conditions in

162-628: A commonly used indicator. With helminth egg analysis, eggs are extracted from the sample after which a viability test is done to distinguish between viable and non viable eggs. The viable fraction of the helminth eggs in the sample is then counted. In the year 2016, the Sustainable Development Goals replaced the Millennium Development Goals. Sanitation is a global development priority and included Sustainable Development Goal 6 (SDG 6). The target

243-657: A defense mechanism". The following types of diarrhea may indicate further investigation is needed: A severity score is used to aid diagnosis in children. When diarrhea lasts for more than four weeks a number of further tests may be recommended including: A 2019 guideline recommended that testing for ova and parasites was only needed in people who are at high risk though they recommend routine testing for giardia . Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were not recommended. Worldwide in 2004, approximately 2.5 billion cases of diarrhea occurred, which resulted in 1.5 million deaths among children under

324-470: A few cases such as those who have bloody diarrhea and a high fever, those with severe diarrhea following travelling , and those who grow specific bacteria or parasites in their stool. Loperamide may help decrease the number of bowel movements but is not recommended in those with severe disease. About 1.7 to 5 billion cases of diarrhea occur per year. It is most common in developing countries , where young children get diarrhea on average three times

405-427: A few. A range of sanitation technologies and approaches exists. Some examples are community-led total sanitation , container-based sanitation , ecological sanitation , emergency sanitation , environmental sanitation, onsite sanitation and sustainable sanitation . A sanitation system includes the capture, storage, transport, treatment and disposal or reuse of human excreta and wastewater . Reuse activities within

486-689: A frequent cause. In the elderly, particularly those who have been treated with antibiotics for unrelated infections, a toxin produced by Clostridioides difficile often causes severe diarrhea. Parasites, particularly protozoa e.g., Cryptosporidium spp., Giardia spp., Entamoeba histolytica , Blastocystis spp., Cyclospora cayetanensis , are frequently the cause of diarrhea that involves chronic infection. The broad-spectrum antiparasitic agent nitazoxanide has shown efficacy against many diarrhea-causing parasites. Other infectious agents, such as parasites or bacterial toxins, may exacerbate symptoms. In sanitary living conditions where there

567-514: A healthy living environment for everyone, to protect the natural resources (such as surface water , groundwater , soil ), and to provide safety, security and dignity for people when they defecate or urinate . The Human Right to Water and Sanitation was recognized by the United Nations (UN) General Assembly in 2010. It has been recognized in international law through human rights treaties , declarations and other standards. It

648-413: A high glucose content are more absorbable and less likely to cause diarrhea. Sugar alcohols such as sorbitol (often found in sugar-free foods) are difficult for the body to absorb and, in large amounts, may lead to osmotic diarrhea. In most of these cases, osmotic diarrhea stops when the offending agent (e.g., milk or sorbitol) is stopped. Exudative diarrhea occurs with the presence of blood and pus in

729-435: A liquid, or "loose", bowel movement. Acute diarrhea is most commonly due to viral gastroenteritis with rotavirus , which accounts for 40% of cases in children under five. In travelers , however, bacterial infections predominate. Various toxins such as mushroom poisoning and drugs can also cause acute diarrhea. Chronic diarrhea can be the part of the presentations of a number of chronic medical conditions affecting

810-435: A new term: "basic sanitation service". This is defined as the use of improved sanitation facilities that are not shared with other households. A lower level of service is now called "limited sanitation service" which refers to use of improved sanitation facilities that are shared between two or more households. Community-based sanitation is related to decentralized wastewater treatment (DEWATS). The term "dry sanitation"

891-464: A population, especially in the absence of water filtration or purification. Human feces contains a variety of potentially harmful human pathogens . Proper nutrition is important for health and functioning, including the prevention of infectious diarrhea. It is especially important to young children who do not have a fully developed immune system. Zinc deficiency , a condition often found in children in developing countries can, even in mild cases, have

972-414: A result, if it is stopped, there might be a delay in recovery. They cite in support of this argument research published in 1973 that found that treating Shigella with the anti-diarrhea drug (Co-phenotrope, Lomotil ) caused people to stay feverish twice as long as those not so treated. The researchers indeed themselves observed that: "Lomotil may be contraindicated in shigellosis. Diarrhea may represent

1053-435: A series of tests of intelligence. Diarrhea can cause electrolyte imbalances , kidney impairment , dehydration , and defective immune system responses. When oral drugs are administered, the efficiency of the drug is to produce a therapeutic effect and the lack of this effect may be due to the medication travelling too quickly through the digestive system, limiting the time that it can be absorbed. Clinicians try to treat

1134-438: A significant impact on the development and proper functioning of the human immune system. Indeed, this relationship between zinc deficiency and reduced immune functioning corresponds with an increased severity of infectious diarrhea. Children who have lowered levels of zinc have a greater number of instances of diarrhea, severe diarrhea, and diarrhea associated with fever. Similarly, vitamin A deficiency can cause an increase in

1215-806: A week over the previous three months. Symptoms of diarrhea-predominant IBS can be managed through a combination of dietary changes, soluble fiber supplements and medications such as loperamide or codeine . About 30% of patients with diarrhea-predominant IBS have bile acid malabsorption diagnosed with an abnormal SeHCAT test. Diarrhea can be caused by other diseases and conditions, namely: Over 700 medications, such as penicillin , are known to cause diarrhea. The classes of medications that are known to cause diarrhea are laxatives, antacids, heartburn medications, antibiotics, anti-neoplastic drugs, anti-inflammatories as well as many dietary supplements. According to two researchers, Nesse and Williams , diarrhea may function as an evolved expulsion defense mechanism. As

1296-484: A year. Total deaths from diarrhea are estimated at 1.53 million in 2019—down from 2.9 million in 1990. In 2012, it was the second most common cause of deaths in children younger than five (0.76 million or 11%). Frequent episodes of diarrhea are also a common cause of malnutrition and the most common cause in those younger than five years of age. Other long term problems that can result include stunted growth and poor intellectual development. The word diarrhea

1377-430: Is isotonic with plasma even during fasting. It continues even when there is no oral food intake. Osmotic diarrhea occurs when too much water is drawn into the bowels. If a person drinks solutions with excessive sugar or excessive salt, these can draw water from the body into the bowel and cause osmotic diarrhea. Osmotic diarrhea can also result from maldigestion (e.g., pancreatic disease or coeliac disease ) in which

1458-646: Is a symptom of, among others, Shigella , Entamoeba histolytica , and Salmonella . Diarrheal disease may have a negative impact on both physical fitness and mental development. "Early childhood malnutrition resulting from any cause reduces physical fitness and work productivity in adults", and diarrhea is a primary cause of childhood malnutrition. Further, evidence suggests that diarrheal disease has significant impacts on mental development and health; it has been shown that, even when controlling for helminth infection and early breastfeeding, children who had experienced severe diarrhea had significantly lower scores on

1539-498: Is about "clean water and sanitation for all" by 2030. It is estimated that 660 million people still lacked access to safe drinking water as of 2015. Since the COVID-19 pandemic in 2020, the fight for clean water and sanitation is more important than ever. Handwashing is one of the most common prevention methods for Coronavirus, yet two out of five people do not have access to a hand-washing station. The United Nations , during

1620-670: Is also referred to as water reclamation . Sanitation systems in urban areas of developed countries usually consist of the collection of wastewater in gravity driven sewers, its treatment in wastewater treatment plants for reuse or disposal in rivers, lakes or the sea. In developing countries most wastewater is still discharged untreated into the environment. Alternatives to centralized sewer systems include onsite sanitation , decentralized wastewater systems , dry toilets connected to fecal sludge management . Sewers are either combined with storm drains or separated from them as sanitary sewers . Combined sewers are usually found in

1701-479: Is ample food and a supply of clean water, an otherwise healthy person usually recovers from viral infections in a few days. However, for ill or malnourished individuals, diarrhea can lead to severe dehydration and can become life-threatening. Open defecation is a leading cause of infectious diarrhea leading to death. Poverty is a good indicator of the rate of infectious diarrhea in a population. This association does not stem from poverty itself, but rather from

1782-442: Is an increase in the active secretion, or there is an inhibition of absorption. There is little to no structural damage. The most common cause of this type of diarrhea is a cholera toxin that stimulates the secretion of anions , especially chloride ions (Cl ). Therefore, to maintain a charge balance in the gastrointestinal tract , sodium (Na ) is carried with it, along with water. In this type of diarrhea intestinal fluid secretion

1863-535: Is an infection of the intestines due to a virus , bacterium , or parasite —a condition also known as gastroenteritis . These infections are often acquired from food or water that has been contaminated by feces , or directly from another person who is infected. The three types of diarrhea are: short duration watery diarrhea, short duration bloody diarrhea, and persistent diarrhea (lasting more than two weeks, which can be either watery or bloody). The short duration watery diarrhea may be due to cholera , although this

1944-584: Is best known in humans, it affects many other species, notably among primates . The cecal appendix , when present, appears to afford some protection against diarrhea to young primates. Numerous studies have shown that improvements in drinking water and sanitation ( WASH ) lead to decreased risks of diarrhoea. Such improvements might include for example use of water filters, provision of high-quality piped water and sewer connections. In institutions, communities, and households, interventions that promote hand washing with soap lead to significant reductions in

2025-539: Is defined by the World Health Organization as having three or more loose or liquid stools per day, or as having more stools than is normal for that person. Acute diarrhea is defined as an abnormally frequent discharge of semisolid or fluid fecal matter from the bowel, lasting less than 14 days, by World Gastroenterology Organization . Acute diarrhea that is watery may be known as AWD (Acute Watery Diarrhoea.) Secretory diarrhea means that there

2106-929: Is derived from the human right to an adequate standard of living . Effective sanitation systems provide barriers between excreta and humans in such a way as to break the disease transmission cycle (for example in the case of fecal-borne diseases). This aspect is visualised with the F-diagram where all major routes of fecal-oral disease transmission begin with the letter F: feces, fingers, flies, fields, fluids, food. Sanitation infrastructure has to be adapted to several specific contexts including consumers' expectations and local resources available. Sanitation technologies may involve centralized civil engineering structures like sewer systems , sewage treatment , surface runoff treatment and solid waste landfills . These structures are designed to treat wastewater and municipal solid waste . Sanitation technologies may also take

2187-674: Is from the Ancient Greek διάρροια from διά dia "through" and ῥέω rheo "flow". Diarrhea is the spelling in American English , whereas diarrhoea is the spelling in British English . Slang terms for the condition include "the runs", "the squirts" (or "squits" in Britain ) and "the trots". The word is often pronounced as / ˌ d aɪ ə ˈ r iː ə / DY -ə- REE -ə . Diarrhea

2268-476: Is made from Stainless Steel 316L, (an alloy containing small amounts of molybdenum ). The surface is usually electropolished to an effective surface roughness of less than 0.5 micrometre to reduce the possibility of bacterial adhesion. In many settings, provision of sanitation facilities alone does not guarantee good health of the population. Studies have suggested that the impact of hygiene practices have as great an impact on sanitation related diseases as

2349-582: Is most commonly conducted in landfills , but incineration, recycling , composting and conversion to biofuels are also avenues. In the case of landfills, advanced countries typically have rigid protocols for daily cover with topsoil, where underdeveloped countries customarily rely upon less stringent protocols. The importance of daily cover lies in the reduction of vector contact and spreading of pathogens . Daily cover also minimizes odor emissions and reduces windblown litter. Likewise, developed countries typically have requirements for perimeter sealing of

2430-616: Is not in widespread use and is not very well defined. It usually refers to a system that uses a type of dry toilet and no sewers to transport excreta. Often when people speak of "dry sanitation" they mean a sanitation system that uses urine-diverting dry toilet (UDDTs). Environmental sanitation encompasses the control of environmental factors that are connected to disease transmission . Subsets of this category are solid waste management, water and wastewater treatment, industrial waste treatment and noise pollution control. According to World health organization (WHO) Environmental sanitation

2511-592: Is not shared with other households, and where the excreta produced is either treated and disposed in situ, stored temporarily and then emptied and transported to treatment off-site, or transported through a sewer with wastewater and then treated off-site. In other words, safely managed sanitation is a basic sanitation service where in addition excreta are safely disposed of in situ or transported and treated offsite. Wastewater management consists of collection, wastewater treatment (be it municipal or industrial wastewater ), disposal or reuse of treated wastewater. The latter

2592-629: 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 . 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

2673-437: Is rare in the developed world. If blood is present, it is also known as dysentery . A number of non-infectious causes can result in diarrhea. These include lactose intolerance , irritable bowel syndrome , non-celiac gluten sensitivity , celiac disease , inflammatory bowel disease such as ulcerative colitis , hyperthyroidism , bile acid diarrhea , and a number of medications. In most cases, stool cultures to confirm

2754-554: Is the condition of having at least three loose, liquid, or watery bowel movements in a day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination , loss of skin color , a fast heart rate , and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed , however, are normal. The most common cause

2835-536: Is the most common cause in children under five years old. Adenovirus types 40 and 41, and astroviruses cause a significant number of infections. Shiga-toxin producing Escherichia coli , such as E coli o157:h7 , are the most common cause of infectious bloody diarrhea in the United States. Campylobacter spp. are a common cause of bacterial diarrhea, but infections by Salmonella spp., Shigella spp. and some strains of Escherichia coli are also

2916-442: Is usually open defecation (and open urination but this is of less concern) with associated serious public health issues. It is estimated that 2.4 billion people still lacked improved sanitation facilities including 660 million people who lack access to safe drinking water as of 2015. Onsite sanitation (or on-site sanitation) is defined as "a sanitation system in which excreta and wastewater are collected and stored or treated on

2997-488: The Joint Monitoring Programme in 2016 starts at open defecation and moves upwards using the terms "unimproved", "limited", "basic", with the highest level being " safely managed ". This is particularly applicable to developing countries . The Human Right to Water and Sanitation was recognized by the United Nations (UN) General Assembly in 2010. Sanitation is a global development priority and

3078-753: The United Nations Development Programme (UNDP) Human Development Report in 2006 has shown, progress meeting the MDG sanitation target is slow, with a large gap between the target coverage and the current reality. In December 2006, the United Nations General Assembly declared 2008 "The International Year of Sanitation ", in recognition of the slow progress being made towards the MDGs sanitation target. The year aimed to develop awareness and more actions to meet

3159-562: The WASH sector only include excreta management in their definition of sanitation. Another example of what is included in sanitation is found in the handbook by Sphere on "Humanitarian Charter and Minimum Standards in Humanitarian Response" which describes minimum standards in four "key response sectors" in humanitarian response situations. One of them is "Water Supply, Sanitation and Hygiene Promotion" ( WASH ) and it includes

3240-503: The "mortality rate attributed to unsafe water, sanitation, and lack of hygiene". When analyzing environmental samples, various types of indicator organisms are used to check for fecal pollution of the sample. Commonly used indicators for bacteriological water analysis include the bacterium Escherichia coli (abbreviated as E. coli) and non-specific fecal coliforms . With regards to samples of soil , sewage sludge , biosolids or fecal matter from dry toilets , helminth eggs are

3321-477: The 'software' (regulation, hygiene promotion) needed to reduce faecal-oral disease transmission. It encompasses too the re-use and ultimate disposal of human excreta. The term environmental sanitation is used to cover the wider concept of controlling all the factors in the physical environment which may have deleterious impacts on human health and well-being. In developing countries, it normally includes drainage, solid waste management, and vector control, in addition to

3402-726: The Millennium Summit in New York in 2000 and the 2002 World Summit on Sustainable Development in Johannesburg, developed the Millennium Development Goals (MDGs) aimed at poverty eradication and sustainable development. The specific sanitation goal for the year 2015 was to reduce by half the number of people who had no access to potable water and sanitation in the baseline year of 1990. As the JMP and

3483-487: The Sustainable Development Goal 6.2, Indicator 6.2.1, as the "Proportion of population using (a) safely managed sanitation services and (b) a hand-washing facility with soap and water". The current value in the 2017 baseline estimate by JMP is that 4.5 billion people currently do not have safely managed sanitation. Safely managed sanitation is defined as an improved sanitation facility which

3564-656: The activities covered by the definition of sanitation." Sanitation can include personal sanitation and public hygiene. Personal sanitation work can include handling menstrual waste , cleaning household toilets , and managing household garbage . Public sanitation work can involve garbage collection, transfer and treatment ( municipal solid waste management ), cleaning drains, streets, schools, trains, public spaces , community toilets and public toilets , sewers , operating sewage treatment plants , etc. Workers who provide these services for other people are called sanitation workers . The overall purposes of sanitation are to provide

3645-620: The actual provision of sanitation facilities. Hygiene promotion is therefore an important part of sanitation and is usually key in maintaining good health. Hygiene promotion is a planned approach of enabling people to act and change their behavior in an order to reduce and/or prevent incidences of water, sanitation and hygiene ( WASH ) related diseases. It usually involves a participatory approach of engaging people to take responsibility of WASH services and infrastructure including its operation and maintenance. The three key elements of promoting hygiene are; mutual sharing of information and knowledge,

3726-610: The age of five. Greater than half of these were in Africa and South Asia. This is down from a death rate of 4.5 million in 1980 for gastroenteritis. Diarrhea remains the second leading cause of infant mortality (16%) after pneumonia (17%) in this age group. The majority of such cases occur in the developing world, with over half of the recorded cases of childhood diarrhea occurring in Africa and Asia , with 696 million and 1.2 billion cases, respectively, compared to only 480 million in

3807-418: The area. Cornelius Zalukhu has been the local governor of the kecamatan . Lahewa is approximately 80 kilometres (50 mi) by road from the regional capital of Gunung Sitoli . In 2001 the subdistrict had a population of 26,548 people, in an area covering 446.05 square kilometres (172.22 sq mi). It contains 21 desa / kelurahan (village communities). The third largest settlement on Nias Island,

3888-419: The bloodstream via the intestinal tract in the small intestine. Prior to defecation, the large intestine reabsorbs the water and other digestive solvents in the waste product in order to maintain proper hydration and overall equilibrium. Diarrhea occurs when the large intestine is prevented, for any number of reasons, from sufficiently absorbing the water or other digestive fluids from fecal matter, resulting in

3969-408: The central, older parts or urban areas. Heavy rainfall and inadequate maintenance can lead to combined sewer overflows or sanitary sewer overflows , i.e., more or less diluted raw sewage being discharged into the environment. Industries often discharge wastewater into municipal sewers, which can complicate wastewater treatment unless industries pre-treat their discharges. Disposal of solid waste

4050-455: The conditions under which impoverished people live. The absence of certain resources compromises the ability of the poor to defend themselves against infectious diarrhea. "Poverty is associated with poor housing, crowding, dirt floors, lack of access to clean water or to sanitary disposal of fecal waste ( sanitation ), cohabitation with domestic animals that may carry human pathogens, and a lack of refrigerated storage for food, all of which increase

4131-637: The diarrheas by reducing the dosage of medication, changing the dosing schedule, discontinuation of the drug, and rehydration. The interventions to control the diarrhea are not often effective. Diarrhea can have a profound effect on the quality of life because fecal incontinence is one of the leading factors for placing older adults in long term care facilities (nursing homes). In the latter stages of human digestion, ingested materials are inundated with water and digestive fluids such as gastric acid , bile , and digestive enzymes in order to break them down into their nutrient components, which are then absorbed into

4212-494: The economic costs of inadequate sanitation is a huge concern. For example, according to a World Bank study, economic losses due to inadequate sanitation to The Indian economy are equivalent to 6.4% of its GDP. Most of these are due to premature mortality, time lost in accessing, loss of productivity, additional costs for healthcare among others. Inadequate sanitation also leads to loss from potential tourism revenue. This study also found that impacts are disproportionately higher for

4293-469: The exact cause are not required. Diarrhea can be prevented by improved sanitation , clean drinking water , and hand washing with soap. Breastfeeding for at least six months and vaccination against rotavirus is also recommended. Oral rehydration solution (ORS)—clean water with modest amounts of salts and sugar —is the treatment of choice. Zinc tablets are also recommended. These treatments have been estimated to have saved 50 million children in

4374-412: The experience of the user, excreta and wastewater collection methods, transporting and treatment of waste, and reuse or disposal. All need to be thoroughly considered. The benefits to society of managing human excreta are considerable, for public health as well as for the environment. As a rough estimate: For every US$ 1 spent on sanitation, the return to society is US$ 5.50. For developing countries,

4455-490: The fact that sanitation includes wastewater treatment, the two terms are often used side by side as "sanitation and wastewater management". Another definition is in the DFID guidance manual on water supply and sanitation programmes from 1998: "For the purposes of this manual, the word 'sanitation' alone is taken to mean the safe management of human excreta. It therefore includes both the 'hardware' (e.g. latrines and sewers) and

4536-457: The fecal sludge that is generated onsite is treated at an offsite location. Wastewater ( sewage ) is only generated when piped water supply is available within the buildings or close to them. A related term is a decentralized wastewater system which refers in particular to the wastewater part of on-site sanitation. Similarly, an onsite sewage facility can treat the wastewater generated locally. The global methane emissions from NSSS in 2020

4617-493: The following areas: Hygiene promotion, water supply , excreta management, vector control , solid waste management and WASH in disease outbreaks and healthcare settings. Hygiene promotion is seen by many as an integral part of sanitation. The Water Supply and Sanitation Collaborative Council defines sanitation as "The collection, transport, treatment and disposal or reuse of human excreta , domestic wastewater and solid waste, and associated hygiene promotion." Despite

4698-454: The food and biopharmaceutical industries, the term "sanitary equipment" means equipment that is fully cleanable using clean-in-place (CIP) and sterilization-in-place (SIP) procedures: that is fully drainable from cleaning solutions and other liquids . The design should have a minimum amount of deadleg, or areas where the turbulence during cleaning is insufficient to remove product deposits. In general, to improve cleanability, this equipment

4779-415: The form of relatively simple onsite sanitation systems. This can in some cases consist of a simple pit latrine or other type of non-flush toilet for the excreta management part. Providing sanitation to people requires attention to the entire system, not just focusing on technical aspects such as the toilet , fecal sludge management or the wastewater treatment plant. The "sanitation chain" involves

4860-504: The frequency of diarrhea   ... Poverty also restricts the ability to provide age-appropriate, nutritionally balanced diets or to modify diets when diarrhea develops so as to mitigate and repair nutrient losses. The impact is exacerbated by the lack of adequate, available, and affordable medical care." One of the most common causes of infectious diarrhea is a lack of clean water. Often, improper fecal disposal leads to contamination of groundwater. This can lead to widespread infection among

4941-632: The incidence of diarrhea. The same applies to preventing open defecation at a community-wide level and providing access to improved sanitation . This includes use of toilets and implementation of the entire sanitation chain connected to the toilets (collection, transport, disposal or reuse of human excreta ). There is limited evidence that safe disposal of child or adult feces can prevent diarrheal disease. Sanitation 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

5022-429: The intestine. Common causes include ulcerative colitis , Crohn's disease , microscopic colitis , celiac disease , irritable bowel syndrome , and bile acid malabsorption . There are many causes of infectious diarrhea, which include viruses , bacteria and parasites. Infectious diarrhea is frequently referred to as gastroenteritis . Norovirus is the most common cause of viral diarrhea in adults, but rotavirus

5103-516: The landfill with clay-type soils to minimize migration of leachate that could contaminate groundwater (and hence jeopardize some drinking water supplies). For incineration options, the release of air pollutants , including certain toxic components is an attendant adverse outcome. Recycling and biofuel conversion are the sustainable options that generally have superior lifecycle costs, particularly when total ecological consequences are considered. Composting value will ultimately be limited by

5184-793: The market demand for compost product. Sanitation within the food industry means the adequate treatment of food-contact surfaces by a process that is effective in destroying vegetative cells of microorganisms of public health significance, and in substantially reducing numbers of other undesirable microorganisms, but without adversely affecting the food or its safety for the consumer ( U.S. Food and Drug Administration , Code of Federal Regulations , 21CFR110, USA). Sanitation Standard Operating Procedures are mandatory for food industries in United States . Similarly, in Japan, food hygiene has to be achieved through compliance with food sanitation law. In

5265-557: The mobilization of affected communities and the provision of essential material and facilities. The WHO has investigated which proportion of death and disease worldwide can be attributed to insufficient WASH services. In their analysis they focus on the following four health outcomes: diarrhea , acute respiratory infections , malnutrition , and soil-transmitted Helminthiasis (STHs). These health outcomes are also included as an indicator for achieving Sustainable Development Goal 3 ("Good Health and Well-being"): Indicator 3.9.2 reports on

5346-575: The nutrients are left in the lumen to pull in water. Or it can be caused by osmotic laxatives (which work to alleviate constipation by drawing water into the bowels). In healthy individuals, too much magnesium , vitamin C or undigested lactose can produce osmotic diarrhea and distention of the bowel. A person who has lactose intolerance can have difficulty absorbing lactose after an extraordinarily high intake of dairy products. In persons who have fructose malabsorption , excess fructose intake can also cause diarrhea. High-fructose foods that also have

5427-417: The other types of diarrhea can be found in this type of diarrhea. It can be caused by bacterial infections, viral infections, parasitic infections, or autoimmune problems such as inflammatory bowel diseases. It can also be caused by tuberculosis, colon cancer, and enteritis. If there is blood visible in the stools, it is also known as dysentery . The blood is a trace of an invasion of bowel tissue. Dysentery

5508-403: The past 25 years. When people have diarrhea it is recommended that they continue to eat healthy food, and babies continue to be breastfed. If commercial ORS is not available, homemade solutions may be used. In those with severe dehydration, intravenous fluids may be required. Most cases, however, can be managed well with fluids by mouth. Antibiotics , while rarely used, may be recommended in

5589-561: The plot where they are generated". Another term that is used for the same system is non-sewered sanitation systems (NSSS), which are prevalent in many countries. NSSS play a vital role in the safe management of fecal sludge, accounting for approximately half of all existing sanitation provisions. The degree of treatment may be variable, from none to advanced. Examples are pit latrines (no treatment) and septic tanks ( primary treatment of wastewater). On-site sanitation systems are often connected to fecal sludge management (FSM) systems where

5670-530: The poor, women and children. Availability of toilet at home on the other hand, positively contributes to economic well-being of women as it leads to an increase in literacy and participation in labor force. The term sanitation is connected with various descriptors or adjectives to signify certain types of sanitation systems (which may deal only with human excreta management or with the entire sanitation system, i.e. also greywater, stormwater and solid waste management) – in alphabetical order: In 2017, JMP defined

5751-512: The potential for increased risk of disease contraction. Malabsorption is the inability to absorb food fully, mostly from disorders in the small bowel, but also due to maldigestion from diseases of the pancreas . Causes include: The two overlapping types here are of unknown origin: Another possible cause of diarrhea is irritable bowel syndrome (IBS), which usually presents with abdominal discomfort relieved by defecation and unusual stool (diarrhea or constipation ) for at least three days

5832-751: The rest of the world. Infectious diarrhea resulted in about 0.7 million deaths in children under five years old in 2011 and 250 million lost school days.
