Soil-transmitted helminth and schistosomes are great public health problems in several tropical and subtropical developing countries with poor socio-economic status and personal hygiene.
Almost all of the fatal cases of helminthic infection in the United States are caused by an autoinfecting nematode.
Experiments conducted by Dr. David Elliott, et al at the University of Iowa using mice with experimental inflammatory bowel disease showed that helminthic worms protected the animals from this disease.
The Ethiopians recommend that ‘deworming is a low-cost and feasible treatment in the setting of developing countries, where helminthic infections are widespread, and TB and HIV are rampant’.
Humans and other animals have been living with helminths , or worms, since the dawn of time, and our intestinal tracts have adapted to their presence.
The most common helminths are tapeworms and roundworms.
Harmless worms called helminths can also be useful in helping to train the immune system.
Chronic inflammation, a common feature of helminthic infections, has been proposed to play a key role in carcinogenesis induced by parasites.
Large household size has been reported to increase the risk of helminthic infection, possibly due to increased contamination of the local environment, thereby increasing the chance of infection in the members of the household.
The cnidarians (hydra, jellyfish, and sea anemones) and helminths have a sac-like digestive system with a single opening.
