Infection of this parasite via skin penetration.

Explanation:
Infections that start through skin penetration are typical of certain nematodes whose infective larvae in soil can bore through the host’s skin. Strongyloides stercoralis does this: its infective larvae penetrate the skin, migrate via the bloodstream to the lungs, are coughed up and swallowed, and then mature in the intestines. This route is distinctive from other parasites listed, which are acquired by ingesting eggs or cysticerci in intermediate hosts or contaminated sources rather than through the skin.
