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.
"Human infections with the helminth species Strongyloides stercoralis encompass a wide clinical spectrum, ranging from asymptomatic carriage to life-threatening disease. The diagnosis of S. stercoralis is cumbersome and the sensitivity of conventional stool microscopy is low. New molecular tools have been developed to increase sensitivity. We compared the diagnostic accuracy of real-time PCR with microscopy for the detection of S. stercoralis and hookworm in human stool samples.
