Hookworm Infection

Hookworm infection is a parasitic helminthic disease caused by Ancylostoma duodenale or Necator americanus. It is transmitted via soil contaminated with human feces. The larvae penetrate human skin, migrate through the bloodstream to the lungs, are swallowed, and mature in the small intestine, where they attach to the mucosa and feed on host blood, leading to iron-deficiency anemia and protein malnutrition.

Caused primarily by Necator americanus (predominant worldwide) and Ancylostoma duodenale. Infection occurs when infective filariform larvae in moist, warm soil penetrate intact skin.

Larvae enter the dermis, migrate via the venous/lymphatic system to the lungs, break into alveoli, ascend the bronchial tree, are coughed up, and swallowed. In the duodenum/jejunum, they attach via mouthparts, secreting anticoagulants and causing localized bleeding and mucosal inflammation.

Endemic in tropical and subtropical regions. Affects approximately 500 million people globally, predominantly in impoverished areas with poor sanitation.

Walking barefoot in contaminated soil, open defecation, agricultural labor, poor sanitation, and lack of potable water.

A. Early Symptoms

• Pruritic maculopapular rash (ground itch) at site of entry. B. Common Symptoms


• Abdominal pain, epigastric discomfort, nausea, diarrhea, and generalized fatigue. C. Advanced Symptoms


• Iron-deficiency anemia, pica (eating dirt), peripheral edema, pallor, and dyspnea. D. Emergency Symptoms


• Severe gastrointestinal hemorrhage, signs of high-output heart failure due to anemia.

Pallor (mucosa/nail beds), tachycardia, systolic murmurs, peripheral edema, and occasionally wheezing during the pulmonary migratory phase.

A. Clinical Assessment: History of travel to endemic areas and clinical signs of anemia.
B. Laboratory Testing: Fecal egg count via microscopy.
C. Imaging Studies: Generally not required; chest X-ray may show transient infiltrates.
D. Functional Tests: CBC to assess hemoglobin/hematocrit.
E. Biopsy Findings: Not indicated.
F. Genetic Testing: Not applicable.
G. Differential Diagnosis: Ascariasis, Trichuriasis, peptic ulcer disease, malaria.

Test Name: Stool O&P (Ova and Parasite)
Type: Stool Test
Purpose: Identify hookworm eggs.
Expected Findings: Presence of characteristic oval eggs.
Interpretation: Confirms active infection.

Chest X-ray: Used if pulmonary symptoms occur; may show transient Loeffler’s syndrome (pulmonary infiltrates).

Strongyloidiasis (larva currens), anemia of chronic disease, inflammatory bowel disease.

Severe anemia, heart failure, cognitive impairment in children, stunted growth, hypoalbuminemia.

A. Lifestyle Modifications: Wearing shoes in endemic areas.
B. Preventive Measures: Improved sanitation, mass drug administration.
C. Medical Treatment

• Benzimidazoles (Albendazole 400mg, Mebendazole 100mg) - Mechanism: Inhibition of tubulin polymerization in parasite cells.

Excellent with prompt diagnosis and anthelmintic therapy. Complications arise if chronic anemia is left untreated.

Public health measures including latrine construction, soil hygiene, and periodic deworming programs in schools.
