Soil-transmitted helminth

This article is about the organisms. For the infection, see soil-transmitted helminthiasis.

The soil-transmitted helminths (also called geohelminths) are a group of

lungs and liver. Thus the disease manifestations can be both local and systemic. The geohelminths together present an enormous infection burden on humanity, amounting to 135,000 deaths every year, and persistent infection of more than two billion people.[1][2]

Species

Soil-transmitted helminths are typically from the following

families of nematodes, namely:[citation needed

Diseases

Soil-transmitted helminthiasis

Main article: Soil-transmitted helminthiasis

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]

Soil-transmitted helminthiasis is classified as one of the neglected tropical diseases projected to be controlled/eradicated by 2020 through the London Declaration on Neglected Tropical Diseases.[4]

Strongyloidiasis

Main article: Strongyloidiasis

This is caused by Strongyloides stercoralis. Even though the disease is principally a soil-transmitted helminthiasis, the infection being mediated through contaminated soil, it is however generally omitted in clinical practices and control programmes because of its (allegedly) relatively less significant influence on health and socio-economic conditions. Also it is not restricted to humans, as it is common in pets. But there is an emerging hyperinfection syndrome caused by S. stercoralis, which exhibits a high mortality rate (15% to 87%).[5][6]

General impact

Geohelminth infection is a major health problem particularly in

impaired intellectual performance.[2][7]

Control activities

The World Health Organization is promoting the control of  soil transmitted helminthiasis with large scale, regular distribution of anthelminthics (albendazole or mebendazole) to the population groups more at risk of morbidity (children and women of reproductive age). The number of school-age children treated with PC has progressed steadily from less than 120 million in 2008 to over 450 million in 2018 and is in contiuous espansion.[8]
