context: Infection occurs by eating food or drink contaminated with Ascaris eggs from feces.[2] The eggs hatch in the intestines, burrow through the gut wall, and migrate to the lungs via the blood.[2] There they break into the alveoli and pass up the trachea, where they are coughed up and may be swallowed.[2] The larvae then pass through the stomach for a second time into the intestine, where they become adult worms.[2] It is a type of soil-transmitted helminthiasis and part of a group of diseases called helminthiases.[6]
