Background

  • Morbidity is related to number of worms harbored in intestines

Clinical Features

  • Minor infections are often asymptomatic
  • More severe infections have variety of manifestations including GI symptoms (abdominal pain, diarrhea, blood in stool, rectal prolapse), malaise, weakness, impaired cognitive / physical development, malnutrition[1]

Löffler’s syndrome

  • Characterized by persistent non-productive cough, chest pain, wheezing, rales, pulmonary infiltrates on CXR and marked eosinophilia
  • Result of Ascaris or hookworm larval transit through the lungs

Differential Diagnosis

Helminth infections

Cestodes (Tapeworms)

Trematodes (Flukes)

Nematodes (Roundworms)
