2. Causes

The parasite that causes the giardiasis infection is found in various places but must be ingested to infect humans. Giardia is found in untreated water, such as ponds or lakes. If you accidentally swallow water while swimming in a lake that contains the parasite, you may contract giardiasis. The parasite can also enter the body following poor hygiene habits in an infected area, such as failing to wash the hands sufficiently after using the restroom or cleaning up after pets. Undercooked foods or those washed in infected water and not cooked may also transmit the bacteria. The parasite can spread to others through physical contact.
