After ingestion, the larva bores through the stomach or intestinal wall of the cat and reaches the lungs via the bloodstream. The prepatency period - the time from infection to excretion of the first larvae - is about six weeks. Lungworm infestation rarely causes symptoms of disease in cats, it is considered self-healing.
Helminthiasis, also known as worm infection, is any macroparasitic disease of humans and other animals in which a part of the body is infected with parasitic worms, known as helminths.

[2] Humans are among the many "accidental" or paratenic hosts of these roundworms. [3]
A. lumbricoides is the largest intestinal roundworm and is the most common helminth infection of humans worldwide. Infestation can cause morbidity by compromising nutritional status, [ 3 ] affecting cognitive processes, [ 4 ] inducing tissue reactions such as granuloma to larval stages, and by causing intestinal obstruction , which can be fatal.
