Some A. duodenale larvae, following penetration of the host skin, can become dormant (hypobiosis in the intestine or muscle). These larvae are capable of re-activating and establishing patent, intestinal infections.
The eggs are released into the feces and reside on soil; when deposited on warm, moist soil, a larva rapidly develops in the egg and hatches after 1 to 2 days. This rhabditiform larva moults twice in the soil and becomes a skin-penetrating third-stage infective larva within 5–10 days.

Oct 6, 2022 · Hookworm infection is mainly acquired by walking barefoot on contaminated soil through direct skin penetration by filariform larvae. Ancylostoma duodenale can also be transmitted through the ingestion of larvae.
Apr 10, 2023 · After the eggs of Ancylostoma pass from the stool of their host, the eggs hatch into larvae. In favorable conditions, this occurs in 1 to 2 days. The hatched rhabditiform (non-infective) larvae grow in the feces or soil for 5 to 10 days and mature into filariform (infective) larvae.

Hookworm larvae penetrate the skin when people walk barefoot on or otherwise come into direct contact with infested soil. In humans, larvae of the hookworms Ancylostoma duodenale or Necator americanus travel through the bloodstream to the lungs, penetrate the alveoli, ascend to the epiglottis, are swallowed, and then mature in the intestines.
