[3] Specifically, lack of access to facilities for safe disposal of human waste can result in intestinal parasites and disease.

[4] Parasitic contamination can also occur from eating raw produce,[5] soil-eating behaviour,[6] and low availability of safe drinking water.

[6] Parasites 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.

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 parasites that colonize the gastrointestinal tract.

[citation needed] Due to the wide variety of intestinal parasites, a description of the symptoms rarely is sufficient for diagnosis.

More education was needed to inform the people of the importance of wearing shoes, using latrines (better access to sanitation), and good hygiene.

[7] Intestinal parasite prevention methods are not isolated to specific geographical areas; however, many of the research-based interventions have primarily taken place in underdeveloped countries and regions, where sanitation is a large concern for spreading disease.
