Soil-transmitted helminths are essentially intestinal parasites and their eggs which are liberated along with the faeces of infected persons into the soil. Ascaris and hookworm eggs become infective as they develop into larvae in soil. Infection occurs when vegetables and fruits, contaminated with soil-infested eggs, are consumed; or when hands ...
The soil-transmitted helminths (also called geohelminths) are a group of intestinal parasites belonging to the phylum Nematoda that are transmitted primarily through contaminated soil. They are so called because they have a direct life cycle which requires no intermediate hosts or vectors , and the parasitic infection occurs through faecal ...
WHO have since 2001 had a strategy for control of soil-transmitted helminths, including whipworms. This strategy entails treating at-risk individuals in the endemic areas. Risk groups for whipworm infections are children at preschool and school-aged children, people with specific high-risk jobs, women in reproductive and pregnant and ...
The soil-transmitted helminths (A. lumbricoides, T. trichiura, N. americanus, A. duodenale), schistosomes, and filarial worms collectively infect more than a quarter of the human population worldwide at any one time, far surpassing HIV and malaria together. [35] [37] Schistosomiasis is the second most prevalent parasitic disease of humans after ...
Trichuriasis belongs to the group of soil-transmitted helminthiases. [9] Prevention is by properly cooking food and hand washing before cooking. [5] Other measures include improving access to sanitation such as ensuring use of functional and clean toilets [5] and access to clean water. [10]
This is a particularly serious problem in helminth parasites of small ruminant farm animals. [12] There are many factors that contribute to anthelmintic resistance, such as frequent, mass anthelmintic treatment, underdosing, treating repeatedly with only one anthelmintic, and resistance being transmitted during transfer of animals. [12]
Mass deworming campaigns of school children have been used both as a preventive as well as a treatment method for helminthiasis, which includes soil transmitted helminthiasis in children. Children can be treated by administering, for example, mebendazole and albendazole. The cost is relatively low.
Parasitic worms (helminths) are the cause of soil-transmitted helminthiases. They are classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa. Unlike the flatworms, nematodes have a tubular digestive system, with openings at both ends.
