Ascariasis commonly has higher infection rates compared to other parasite species and because of poor sanitation the parasite can be seen in 100آ % of the population. A. lumbricoides depending on the provocation by anesthetic agents or intestines becomes hostile, such as with inflammation and obstruction, may cause migration and varies complications such as coming up to the mouth or blocking some ducts.
