Ascaris infection occurs about 9-12 days after egg ingestion. The eggs are primarily transmitted from hand to mouth, but they may also be ingested in raw fruits and vegetables grown in soil contaminated with the eggs of ascaris.
Following ingestion, eggs hatch in the small intestine and the larvae penetrates the intestinal mucosa. The larvae then proceeds to the lungs via the venous circulation and migrates through the alveoli and the bronchial tree, resulting in pulmonary ascariasis.
The larvae are subsequently swallowed and return to the intestines where maturation into adult worms occur.
The fecund female worm produces a very high output of eggs (about 200,000 eggs/day). The eggs are passed in the feces
