Helminthic Infestation in Children –

Helminthic infestations are common in pediatric populations, especially in developing countries where poor sanitation and hygiene contribute to their spread. These infestations can cause malnutrition, anemia, growth retardation, and cognitive impairment in children.


Definition

Helminthic infestation refers to an infection caused by parasitic worms in the gastrointestinal tract, bloodstream, or tissues of the human body.


Classification of Helminths

Helminths are broadly classified into three major groups:

A. Nematodes (Roundworms)

  1. Ascaris lumbricoides (Roundworm)
  2. Ancylostoma duodenale, Necator americanus (Hookworm)
  3. Enterobius vermicularis (Pinworm)
  4. Trichuris trichiura (Whipworm)
  5. Strongyloides stercoralis (Threadworm)

B. Cestodes (Tapeworms)

  1. Taenia solium (Pork tapeworm)
  2. Taenia saginata (Beef tapeworm)
  3. Diphyllobothrium latum (Fish tapeworm)
  4. Hymenolepis nana (Dwarf tapeworm)

C. Trematodes (Flukes)

  1. Schistosoma species (Blood flukes)
  2. Fasciola hepatica (Liver fluke)
  3. Paragonimus westermani (Lung fluke)

Causes and Risk Factors

  • Ingestion of contaminated food or water
  • Walking barefoot in contaminated soil (hookworm)
  • Poor sanitation and hygiene
  • Consumption of undercooked meat or fish
  • Close contact with infected individuals
