Both forms of hookworm disease are transmitted to humans through direct skin penetration (usually in the foot) by hookworm larvae in soil contaminated with feces containing hookworm ova. These ova develop into infectious larvae in 1 to 3 days. Larvae travel through the lymphatics to the pulmonary capillaries, where they penetrate alveoli and move up the bronchial tree to the trachea and epiglottis, where they're swallowed and enter the GI tract. When they reach the small intestine, they mature, attach to the jejunal mucosa, and suck blood, oxygen, and glucose from the intestinal wall. These mature worms then deposit ova, which are excreted in the stool, starting the cycle anew. Hookworm larvae mature in approximately 5 to 6 weeks.
Hookworm disease, affecting billions of people worldwide, is most common in moist tropical and subtropical regions. There's little risk of aquiring hookworm disease in the United States because of advances in sanitization and waste control.

The cause of MF is unknown. Most persons with MF have it for years and it can lead to death, but this is unusual.
In the United States, MF strikes more than 1,000 people of all races annually; most are between ages 40 and 60.

Mites can live their entire life cycles in the skin of humans, causing chronic infection. (The adult mite can survive without a human host for only 2 or 3 days.) The female mite burrows into the skin to lay her eggs, from which larvae emerge to copulate and then reburrow under the skin. (See Scabies: Cause and effect, page 1242.)
Scabies occurs worldwide, primarily in environments marked by overcrowding and poor hygiene, and can be endemic.

The term 'prevalence' of Parasitic Conditions usually refers to the estimated population of people who are managing Parasitic Conditions at any given time. The term 'incidence' of Parasitic Conditions refers to the annual diagnosis rate, or the number of new cases of Parasitic Conditions diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
