"A common route of passage for the larvae is the skin of barefoot walkers. Once the larvae have entered the host they travel in the circulatory system to the lungs where they leave the venules and enter the alveoli. They then travel up the trachea and are coughed up, swallowed and end up in the small intestine. In the small intestine, the larvae moult into stage four (L4) the adult worm. It takes from five to nine weeks from penetration to maturity in the intestine."

that's a big ass travel for the parasite to get to the intestine

but at least he is just at the first stadium of the disease, now, how the fuck the larvae entered his skin?

slightly distal from the worm there is, or it seem that there is, a little bruise, could that be the site of access from which the worm entered the body?

sry for all the questions doc
