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.
Symptoms 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.
Hookworms, bloodfeeding intestinal nematodes, infect nearly one billion people in resource limited countries and are a leading cause of anaemia and malnutrition. Like other nematodes, hookworms lack the capacity to synthesise essential fatty acids de novo and therefore must acquire those from exogenous sources. The cDNA corresponding to a putative Ancylostoma ceylanicum fatty acid and retinol binding protein-1 (AceFAR-1) was amplified from adult hookworm mRNA.
