What happens is that when a person first gets infected, they ingest the microscopic eggs of these worms. These eggs hatch in the small intestine, and then releases larvae that migrate towards a person’s lungs through the bloodstream. When this happens, a person with an infection can also experience lung-related problems such as coughing, shortness of breath, and wheezing.
After about 10-14 days, the worm larvae migrate towards the throat, where an infected person coughs up the larvae and then swallows them.
When the larvae are swallowed, they start to mature into adult worms and develop in a person’s small intestine. Typically, the adult worms stay in the intestine until they die.
But before that happens, the worms will reproduce. Typically, females can lay about 200,000 eggs per day. Some of these eggs can remain in the intestine, where they hatch and start the cycle anew, while others get passed along with a person’s stool.
This infected stool is the main way that people get infected with bulate sa tiyan.
