Editing Ingestion (section)

==Pathogens==
Some [[pathogen]]s are [[transmission (medicine)|transmitted]] via ingestion, including [[virus]]es, [[bacteria]], and [[parasite]]s. Most commonly, this takes place via the [[faecal-oral route]]. An intermediate step is often involved, such as [[drinking water]] contaminated by [[faeces]] or [[food]] prepared by workers who fail to practice adequate [[hand-washing]], and is more common in regions where [[Sewage treatment|untreated]] [[sewage]] is common. [[Disease]]s transmitted via the fecal-oral route include [[hepatitis A]], [[polio]], and [[cholera]].

Some pathogenic organisms are typically ingested by other routes. 
* [[Larva]]e of the parasite ''[[Trichinella]]'' [[cyst|encyst]] within [[muscle]]s and are transmitted when a new [[Host (biology)|host]] eats the infected flesh of a former host animal.<ref>{{cite web | title = Trichinellosis | url = http://www.dpd.cdc.gov/dpdx/HTML/Trichinellosis.htm | publisher = Centers for Disease Control & Prevention | year = 2004 | access-date = 2007-04-17 | archive-date = 2013-12-09 | archive-url = https://web.archive.org/web/20131209005719/http://www.dpd.cdc.gov/dpdx/html/Trichinellosis.htm | url-status = dead }}</ref>
* The parasite ''[[Dracunculus (animal)|Dracunculus]]'' is ingested in [[drinking water]], which is contaminated with larvae released as the parasite emerges from the host's skin.<ref>{{cite web | url = http://www.dpd.cdc.gov/dpdx/HTML/Dracunculiasis.htm | title = Dracunculiasis | publisher = Centers for Disease Control & Prevention | year = 2005 | access-date = 2007-04-17 | archive-date = 2007-04-28 | archive-url = https://web.archive.org/web/20070428161820/http://www.dpd.cdc.gov/DPDx/HTML/Dracunculiasis.htm | url-status = dead }}</ref>
