Three types of soil-transmitted helminthiasis can be distinguished: ascariasis, hookworm infection and whipworm infection. These three types of infection are therefore caused by the large roundworm A. lumbricoides, the hookworms Necator americanus or Ancylostoma duodenale and by the whipworm Trichuris trichiura. It has become the most common ...
In 2014–15, the WHO estimated that approximately 2 billion people were infected with soil-transmitted helminthiases, [6] 249 million with schistosomiasis, [60] 56 million people with food-borne trematodiasis, [61] 120 million with lymphatic filariasis, [62] 37 million people with onchocerciasis, [63] and 1 million people with echinococcosis.

Soil-transmitted helminthiasis is a collective name for the diseases caused by ascaris, whipworm and hookworms in humans. It includes species-specific diseases such as [citation needed] Ascariasis, which is caused by Ascaris lumbricoides; Hookworm diseases (ancylostomiasis and necatoriasis), which are caused by Necator americanus and ...
Helminth eggs can reach the soil when polluted wastewater, sewage sludge or human waste are used as fertilizer. Such soil is often characterized by moist and warm conditions. Therefore, the risk of using contaminated wastewater and sludge in agricultural fields is a real problem, especially in poor countries, where this practice is prevalent.
The cost of treating a child for infection of soil transmitted helminths and schistosomes costs different amounts in different countries when administered as part of mass school-based deworming, but Evidence Action states that their recent programmes cost $0.56 or less per child per dose. [6]
Unlimit Health’s area of focus is the elimination of schistosomiasis and soil-transmitted helminthiases (intestinal worms). [1] Parasitic worms can have a hugely detrimental effect on individuals, including reduced productivity, internal organ damage, impaired child development, reduced school attendance, increased risk of HIV in women and ...
Humans can avoid hookworm infections by avoiding skin-to-soil contact, especially by abstaining from walking barefoot in areas where people often defecate. As such, infection can be controlled through the use of outhouses. [citation needed] Hookworm infection is treatable and has been locally eradicated in many areas.
Soil-transmitted helminthiasis is a neglected tropical disease as a result of infection of intestinal parasites such as roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura), hookworms (Ancylostoma duodenale and Necator americanus), and pinworm/threadworm (Strongyloides stercoralis).
