The prevalence of<unk><unk> s is the highest among children that are living in the poorest communities in developing nations. The most common causes of<unk><unk> s are through consumption of contaminated water, infected soil, inadequate sanitation and hygiene, and improper hygiene. Specifically, lack of access to facilities for safe disposal of human waste can result in<unk><unk> s and disease. Poor hygiene habits or lacking available hygiene resources, such as hand washing facilities, also negatively impact rates of disease.<unk> c contamination can also occur from eating raw produce, soil-eating behaviour, and low availability of safe drinking water.<unk> s can get into the intestines by going through the mouth from uncooked or unwashed food, contaminated water or hands, or by skin contact with larva infected soil; they can also be transferred by the sexual act of anilingus in some cases. When the organisms are swallowed, they move into the intestines, where they can reproduce and cause symptoms. Children are particularly susceptible if they are not thoroughly cleaned after coming into contact with infected soil that is present in environments that they may frequently visit such as sandboxes and school playgrounds. People in developing countries are also at particular risk due to drinking water from sources that may be contaminated with<unk> s that colonize the gastrointestinal tract.
