Hookworms are parasites. This means they live off other living things. Hookworms affect your lungs and small intestine. Humans contract hookworms through roundworm eggs and larvae found in dirt contaminated by feces.
Symtoms include abdominal pain, colic (cramping and excessive crying in infants), intestinal cramps, nausea, fever, blood in your stool, appetite loss, itchy rash.
Most cases of classic hookworm disease can be managed on an outpatient basis with anthelmintic and iron therapy, complemented by appropriate diet. Patients with anemia and malnutrition may require both iron supplements and nutritional support (including folate supplementation). Some patients with severe anemia and congestive heart failure may require hospitalization
"Hookworm is a common, chronic (long-term) parasitic infection that is caused by the worms Necator americanus (Ne-kay-tor a-mare-e-caan-us) and Ancylostoma duodenale (An-cy-clo-stoma duo-dean-al). Only A. duodenale occurs in Australia. Humans are the main reservoir (source) of N. americanus and A. duodenale, and it is estimated that around 20% of the world population carries this parasite. Hookworm is not a Nationally Notifiable Disease."
