What does uncinariasis mean?
Uncinariasis is a parasitic disease caused chiefly by the hookworm Ancylostoma duodenale, although the term has sometimes been used more broadly for hookworm illness. The parasites settle in the small intestine and attach themselves to its lining, where they can cause intestinal bleeding, iron-deficiency anemia, malnutrition, abdominal discomfort, and weakness. The condition is associated especially with inadequate sanitation and poor opportunities for footwear, because infection can occur when people walk on soil contaminated with hookworm larvae. In medical practice, it is closely related to the terms hookworm disease, ancylostomiasis, and necatoriasis. Uncinariasis is significant because it can cause prolonged ill health, particularly in children and pregnant people, even when individual symptoms are initially mild. It is preventable through sanitation, footwear, and appropriate health education, and it is treatable with antiparasitic medicines such as albendazole or mebendazole.
nounAn infectious parasitic disease caused by hookworms, especially Ancylostoma duodenale, that infects the small intestine and may cause iron-deficiency anemia and other nutritional problems.
- The disease caused by hookworm parasites, particularly Ancylostoma duodenale, involving the small intestine and potentially resulting in anemia and malnutrition.
"Uncinariasis is a major health concern in communities where sanitation is inadequate."
"Blood tests showed that the anemia had been aggravated by chronic uncinariasis."
"Health workers in the region screened residents because untreated uncinariasis was widespread."
Rare in ordinary usage; used when referring to multiple cases of the disease.
"The clinic reported several uncinariases among the agricultural workers."
Its name comes from a tiny but literal feature: the hookworms use hook-shaped mouths to grip the intestinal wall.

Where does uncinariasis come from?
The word comes from New Latin uncinariasis, formed from Uncinaria, a former taxonomic name for the relevant hookworms, together with the Greek-derived suffix -iasis, meaning a disease condition. Uncinaria was ultimately based on Latin uncinus, meaning “hook,” in reference to the hook-shaped mouth of the worms. The same Latin root also produced English words such as uncinate and uncinus.
How uncinariasis is actually used
This is specialist medical vocabulary rather than everyday language. It denotes the disease condition, not an individual worm, and is generally encountered in clinical or public-health contexts.
Easily confused with uncinariasis
Ancylostomiasis is a closely overlapping term for infection caused by Ancylostoma hookworms and is often used interchangeably with uncinariasis.
Necatoriasis specifically denotes hookworm infection caused by Necator americanus, whereas uncinariasis traditionally refers especially to infection caused by Ancylostoma duodenale.
