Hookworm Disease

Ancylostomiasis: Ancylostoma duodenale/Necator americanus in small intestine; skin-penetrating filariform larvae. Anemia, malnutrition, GI dysfunction; severe: growth retardation/cardiac insufficiency.

Common Symptoms

Abdominal discomfort; petechiae; dizziness; diarrhea; tinnitus; rhabditiform larvae in sputum; abdominal pain; fatigue; nausea; dyspepsia

Causes and Pathogenesis

Skin: larval dermatitis (vasodilation/hemorrhage/serum exudate; PMN/eosinophil/monocyte/fibroblast infiltrate). Small intestine: buccal capsule attachment → petechiae/3-5 mm erosions/submucosal hemorrhages; edema/infiltrate. Lung: petechiae/infiltrate; heavy migration = pneumonitis/lobar consolidation. Adult anti-coagulant secretion → chronic blood loss/protein loss.

Treatment

Drug therapy, supportive therapy

Preventive Measures

Mass winter treatment; fecal composting; no nightsoil; wear shoes/barrier cream (rosin/iodine/ethanol formula).
