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 ...
The World Health Organization estimates that globally more than 1.5 billion people (24% of the total population) have a soil-transmitted helminth infection. [2] Over 270 million preschool-age children and over 600 million school-age children live in areas where these parasites are intensively transmitted, and need treatment and preventive ...
However, it does not quantify mixed infections, and in practice, is inaccurate for quantifying the eggs of schistosomes and soil-transmitted helminths. [36] Sophisticated tests such as serological assays , antigen tests , and molecular diagnosis are also available; [ 35 ] [ 37 ] however, they are time-consuming, expensive and not always reliable.
Routes of exposure and infection include ingestion of undercooked meat, drinking infected water, fecal–oral transmission and skin absorption. Some types of helminths and protozoa are classified as intestinal parasites that cause infection—those that reside in the intestines. These infections can damage or sicken the host (humans or other ...
Heavy infections can occur in both children and adults, but are less common in adults. [2] They are rarely fatal. [6] Hookworm infection is a soil-transmitted helminthiasis and classified as a neglected tropical disease. [7]
According to the Mayo Clinic, UTIs are commonly caused by bacteria entering the urethra due to sexual intercourse and sexually transmitted infections. The post This Is Why It's So Hard To Get Rid ...
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. Large training efforts funded by the Rockefeller Foundation showed state health departments how to eradicate the disease in the American South during the 1910s. [11] [14] [page needed]
Many of the worms referred to as helminths are intestinal parasites. An infection by a helminth is known as helminthiasis, helminth infection, or intestinal worm infection. There is a naming convention which applies to all helminths: the ending "-asis" (or in veterinary science: "-osis") is added at the end of the name of the worm to denote the ...
