How can helminthiasis be prevented?
Control is based on periodical deworming to eliminate infecting worms, health education to prevent re-infection, and improved sanitation to reduce soil contamination with infective eggs. Safe and effective medicines are available to control infection.
What kind of diseases do parasites cause?
Examples of parasitic diseases that can be bloodborne include African trypanosomiasis, babesiosis, Chagas disease, leishmaniasis, malaria, and toxoplasmosis. In nature, many bloodborne parasites are spread by insects (vectors), so they are also referred to as vector-borne diseases.
How are helminths classified?
Classification. Helminths are invertebrates characterised by elongated, flat or round bodies. Flatworms (platyhelminths) include flukes (trematodes), tapeworms (cestodes) and roundworms (nematodes).

How does helminthiasis affect the health of the host?
Helminthiasis may cause chronic illness through malnutrition including vitamin deficiencies, stunted growth, anemia, and protein-energy malnutrition. Worms compete directly with their hosts for nutrients, but the magnitude of this effect is likely minimal as the nutritional requirements of worms is relatively small.
